Oracle Forms Java HTML Editor Bean Integration manual

1. How can I integrate the HTML Editor in Oracle Forms?

As any other java bean is integrated in Oracle Forms designer. Place the jar file in the designer's classpath and it will be automatically detected by the Oracle Forms Designer. You can add it after that easily as a bean area.
Please note that the delimiter between the jars in the classpath is "," and not ";" - if you put the ";" it will not work properly.

• copy the HTMLEditorPro.jar file in the <ORACLE_HOME>/forms/java directory
• edit your <ORACLE_HOME>/forms/server/formsweb.cfg file (for Oracle Forms 11g it is usually located into the folder <ORACLE_HOME>/Middleware/user_projects/domains/yourdomain/config/fmwconfig/servers/AdminServer/ applications/formsapp_11.1.2/config) to add everywhere the HTMLEditorPro.jar as follows:
  # Forms applet archive setting for JInitiator
  archive_jini=f90all_jinit.jar,HTMLEditorPro.jar
  # Forms applet archive setting for Microsoft Internet Explorer native JVM
  archive_ie=f90all.cab,HTMLEditorPro.jar
  # Forms applet archive setting for other clients (Sun Java Plugin, Appletviewer, etc)
  archive=f90all.jar,HTMLEditorPro.jar
• open the HTMLEditorSampleForm.fmb module (Oracle Forms module)
• if you don't see the editor into the Forms Builder you may need to add the  <ORACLE_HOME>/forms/java/HTMLEditorPro.jar to the system variable classpath
• compile all and run the module
• Into the Oracle Forms Visual designer insert a Bean area and set the implementation property to sferyx.administration.editors.HTMLEditorOracleBean

You can note on the screenshot  below the bean implementation property of the Bean Area is set to sferyx.administration.editors.HTMLEditorOracleBean:

2. How to get the content of the HTML Editor in Oracle Forms?

Invoking a function from PL/SQL:
Declare
vString VarChar2(2000);
Begin
vString := FBean.Invoke_Char('HTMLEDITOR_AREA',1,'getBodyContent');
:block3.TEXT_AREA := vString;
End;

If you want to retrieve the editor content including all document images embedded inside the document  encoded as strings you should use the following method:

public void setEmbedAllImagesInsideTheDocument(boolean embed)

public boolean isEmbedAllImagesInsideTheDocument()

like this:

hArgs:=FBEAN.CREATE_ARGLIST;
FBEAN.ADD_ARG(hArgs,true);
FBean.Invoke('HTMLEDITOR_AREA',1,'setEmbedAllImagesInsideTheDocument',hArgs);

After that by simply retrieving the document content using getContent() or getBodyContent() you will get also all images embedded inside the document as strings and you can save them easily into a CLOB field. See below how to save/retrieve the HTMLEditor content from a CLOB field.

If the content is larger than 4K you will need to use the content buffer methods of the editor because of limitation in the Oracle Forms transfer length. Here is an example on how to retrieve the HTMLEditor content into portions using the methods getBodyContentLength() and getBodyContentPortion()

FUNCTION Get_HTMLEditor_Content RETURN varchar2 IS
l_text varchar2(4000);
l_buffer varchar2(32000);
l_index pls_integer;
l_len pls_integer;
l_length number;
l_done boolean;
hArgs FBEAN.ARGLIST;

BEGIN

l_buffer := null;
l_len := FBean.Invoke_Num('HTMLEDITOR_AREA',1,'getBodyContentLength');

if l_len > 0 then
l_done := FALSE;
hArgs:=FBEAN.CREATE_ARGLIST;
l_index := 1;
else
l_done := TRUE;
end if;

while not l_done loop
FBEAN.ADD_ARG(hArgs,l_index);
FBEAN.ADD_ARG(hArgs,4000);
l_text := FBean.Invoke_char('HTMLEDITOR_AREA',1,'getBodyContentPortion',hArgs);
l_buffer := l_buffer || l_text;
l_index := l_index + 4000;
if l_index > l_len then
l_done := TRUE;
end if;
FBEAN.CLEAR_ARGLIST(hArgs);
end loop;
return(l_buffer);
END;
 

 

3. How to set the content of the HTML Editor in Oracle Forms?

Declare
hArgs FBEAN.ARGLIST;
Begin
hArgs:=FBEAN.CREATE_ARGLIST;
FBEAN.ADD_ARG(hArgs,'some, text');
FBean.Invoke('HTML_EDITOR',1,'setContent',hArgs);

If the content is larger than 4K you will need to use the content buffer methods of the editor because of limitation in the Oracle Forms transfer length. Here is an example on how to use this:

Declare
hArgs FBEAN.ARGLIST;
Begin
hArgs:=FBEAN.CREATE_ARGLIST;

FBEAN.INVOKE('HTML_EDITOR', 1, 'openContentBuffer');
FBEAN.ADD_ARG(hArgs, 'some text here');
FBEAN.INVOKE('HTML_EDITOR', 1, 'appendContentToContentBuffer', hArgs);
FBEAN.CLEAR_ARGLIST(hArgs);
FBEAN.ADD_ARG(hArgs, 'some other text here');
FBEAN.INVOKE('HTML_EDITOR', 1, 'appendContentToContentBuffer', hArgs);
FBEAN.CLEAR_ARGLIST(hArgs);
FBEAN.ADD_ARG(hArgs, 'some other text here');
FBEAN.INVOKE('bHTML_EDITOR', 1, 'appendContentToContentBuffer', hArgs);
FBEAN.CLEAR_ARGLIST(hArgs);
FBEAN.ADD_ARG(hArgs, 'some other text here');
FBEAN.INVOKE('HTML_EDITOR', 1, 'appendContentToContentBuffer', hArgs);
FBEAN.CLEAR_ARGLIST(hArgs);
FBEAN.ADD_ARG(hArgs, 'some other text here');
FBEAN.INVOKE('HTML_EDITOR', 1, 'appendContentToContentBuffer', hArgs);
FBEAN.CLEAR_ARGLIST(hArgs);

FBEAN.INVOKE('HTML_EDITOR', 1, 'closeBufferAndInsert', hArgs);
FBEAN.CLEAR_ARGLIST(hArgs);

 

4. How to set / get the content of the HTML Editor in Oracle Forms from a CLOB field

NOTE: If you want to retrieve the editor content including all document images embedded inside the document  encoded as strings you should use the following method:

public void setEmbedAllImagesInsideTheDocument(boolean embed)

public boolean isEmbedAllImagesInsideTheDocument()

like this:

hArgs:=FBEAN.CREATE_ARGLIST;
FBEAN.ADD_ARG(hArgs,true);
FBean.Invoke('HTMLEDITOR_AREA',1,'setEmbedAllImagesInsideTheDocument',hArgs);

After that by simply retrieving the document content using getContent() or getBodyContent() you will get also all images embedded inside the document as strings and you can save them easily into a CLOB field. See below how to save/retrieve the HTMLEditor content from a CLOB field.

In the downloadable demo in the folder "examples/oracle forms" there is an example which contains the whole code and illustrates how this works.

INSERT INTO EDITOR FROM CLOB
 

For this example the database contains the table EPM_CONTRACT_CONS
and the structure of this table is as follows:

EPM_CONTRACT_CONS
==============================
EMP_NO                                  NUMBER
ASSUMPTION_DESC                 CLOB
 

insert some text into ASSUMPTION_DESC, and set EMP_NO to 1. Here below is the code for inserting the CLOB field content inside the HTMLEditor.

DECLARE
  bean varchar2(200):='HTMLEDITOR_AREA';
  t_id number(20):=1;
  hArgs FBEAN.ARGLIST;
  parts number(20);
  part varchar2(32500);
  part_size number(20) := 4000;
  body_length number(20);
BEGIN

  hArgs := FBEAN.CREATE_ARGLIST;

       -- Init Editor Buffer
      FBean.Invoke(bean,1,'openContentBuffer');
    
      -- Get CLOB content lenghtG(hArgs,part);
          FBean.Invoke(bean,1,'appendContentToContentBuffer',hArgs);
        end loop;   
      select nvl(dbms_lob.getlength(ASSUMPTION_DESC),0) into body_length from EPM_CONTRACT_CONS where EMP_NO = t_id;
    
        
     if body_length > 0 then
        -- Get Length and number of the parts
        select trunc(dbms_lob.getlength(ASSUMPTION_DESC)/ part_size) +1 into parts from EPM_CONTRACT_CONS where EMP_NO = t_id;
      
        for i in 1..parts loop
            select dbms_lob.substr(ASSUMPTION_DESC,part_size,((i-1)*part_size)+1) into part from EPM_CONTRACT_CONS where EMP_NO = t_id;
          
          hArgs := FBEAN.CREATE_ARGLIST;
             FBEAN.ADD_AR
     
      end if;

      -- Populate Editor
      FBean.Invoke(bean,1,'closeBufferAndInsert');

 
END;
 

SAVE INTO CLOB FROM EDITOR

This code is used to illustrate how to transfer the editor content to a CLOB field in the database. See the database table structure described above.

DECLARE

  bean varchar2(200):='HTMLEDITOR_AREA';
  t_id number(20):=1;
  hArgs FBEAN.ARGLIST;
  parts number(20);
  part varchar2(32500);
  body_length number(20);
  r_hd clob := null;
  res_hd clob;
  part_size binary_integer := 4000;
  pos number(20);
  old_length number(20);
  last_part_size binary_integer;
BEGIN

  hArgs := FBEAN.CREATE_ARGLIST;
 
 
  
      body_length := FBean.Invoke_num(bean,1,'getBodyContentLenght');
      parts := trunc(body_length / part_size);
      DBMS_LOB.CREATETEMPORARY(r_hd,TRUE);

      -- Complete Parts
      if parts > 0 then
    
          for i in 1..parts loop
          hArgs := FBEAN.CREATE_ARGLIST;
          pos := ((i-1)*part_size);
            fbean.add_arg(hargs,pos);
            fbean.add_arg(hargs,part_size);
          part := fbean.invoke_char(bean,1,'getBodyContentPortion',hargs);
          dbms_lob.write(r_hd,part_size,pos+1,part);
          end loop;
        
        -- last Part
        hArgs := FBEAN.CREATE_ARGLIST;
        pos := pos + part_size;
        last_part_size := body_length - (parts) * part_size - 1;
          fbean.add_arg(hargs,pos);
          fbean.add_arg(hargs,last_part_size);
        part := fbean.invoke_char(bean,1,'getBodyContentPortion',hargs);
        dbms_lob.write(r_hd,last_part_size,pos+1,part);
      else
        hArgs := FBEAN.CREATE_ARGLIST;
          fbean.add_arg(hargs,0);
          fbean.add_arg(hargs,body_length-1);
        part := fbean.invoke_char(bean,1,'getBodyContentPortion',hargs);
        dbms_lob.write(r_hd,length(part),1,part);
      end if;

      update EPM_CONTRACT_CONS set ASSUMPTION_DESC = r_hd where EMP_NO = t_id;
      DBMS_LOB.FREETEMPORARY(r_hd);

 
END;

 

5. How to enable copy/paste from/to the HTML Editor in Oracle Forms?

You will need to sign the component jar file with your security certificate. In case you may need help with this do not hesitate to contact our customer support at support@sferyx.com

6. How to remove toolbar/menu items in Oracle Forms?

Declare
hArgs2 FBEAN.ARGLIST;
--Here we remove the unwanted toolbar items using arglist
hArgs2:=FBEAN.CREATE_ARGLIST;
FBEAN.ADD_ARG(hArgs2,'newFileButton,openFileButton,saveFileButton');
FBean.Invoke('HTML_EDITOR',1,'setRemovedToolbarItems',hArgs2);
End;

All the names of the toolbar and menu items can be found in the main users manual.

7. Available methods accessible directly from the sferyx.administration.editors.HTMLEditorOracleBean - you should use the same rules for accessing those methods as described above in the OracleForms PL/SQL script examples:

 

public void setEnableCustomEventDispatching(boolean customEventsDispatchingEnabled) - this method allows to enable/disable dispatching of the events from the editor to the underlying form

public boolean isEnableCustomEventDispatching()  - this method returns whether is enabled/disabled dispatching of the events from the editor to the underlying form

public void dispatchOracleFormsEvent(String name, Object event) - this method allows to dispatch events from the editor to the underlying form which will captured into the WHEN-CUSTOM-ITEM-EVENT trigger of the form.

public void setCustomEventDispatchingMask(String eventMask) -This method allows only specified events to be dispatched once they have been enabled through the setEnableCustomEventDispatching. As argument can be specified a comma separated list of event names which are allowed to be dispatched to the  WHEN-CUSTOM-ITEM-EVENT. Example list of event names is as follows: "mouseReleased,insertUpdate,keyTyped" etc. By default all events are enabled through setEnableCustomEventDispatching.
 
public void resetCustomEventDispatchingMask() - will reset the dispatching event mask.

public void setEnableActionEventMaskForUIItems(String uiItemNames,boolean discardDefaultActions)- this method allows to be captured only specific action events from all UI elements such as toolbars and menus. discardDefaultActions specifies whether the default action for the UI element to be suppressed or not. This way you can implement easily your own handlers for all UI items of the editor by disabling the default functionality and implementing a new one.

public void addKeyToKeyEventMask(int keyCode, boolean shiftDown, boolean altDown, boolean ctrlDown, boolean metaDown, boolean altGraphDown) - If key is added to the key event mask only events generated from this key will be dispatched as custom events, others will be ignored . To reset the event mask use resetKeyEventMask method. keyCode is the code of the key on the keyboard. Example Enter is 13, Space bar is 32 etc.

public void resetKeyEventMask() -To reset the event mask use resetKeyEventMask method

So if you want to set key event mask for the F9, Shift+F9 and F10 you will need to do like this:

public void setLTROrientation()- this allows easy reversal of the document depending on the writing system used.


public void setRTLOrientation()


public void setEmbedAllImagesInsideTheDocument(boolean embed) - this new method enables the editor to embed all document images inside the HTML code which is retrieved using getContent(), getBodyContent() methods. This way is possible to create fully self contained documents to be saved as simple strings inside database fields (for example CLOB or similar) or even simple text files.

public boolean isEmbedAllImagesInsideTheDocument()

This methods are very useful in environments where long content strings cannot be inserted at once due to some limitations as happens for example in Oracle Forms. See supplied examples in the users manual.


public int getPlainTextContentLenght() this method returns the length of the plain text content of the editor.


public String getPlainTextContentPortion(int offset, int length) this method returns portion of the plain text content - this should be used in environments where is impossible the whole content at once due to some limitations such as the case of Oracle Forms. This should be used in conjunction with getPlainTextContentLength() and make cycle for retrieving all pieces through getPlainTextContentPortion(int start, in length)


 

8. How to enable capturing the events from the HTML Editor to the form?

This will enable the generation of the events from the editor to the form:

Declare
hArgs FBEAN.ARGLIST;
Begin
hArgs:=FBEAN.CREATE_ARGLIST;
FBEAN.ADD_ARG(hArgs,true);
FBean.Invoke('HTMLEDITOR_AREA',1,'setEnableCustomEventDispatching',hArgs);
End;

This code will capture the events using the WHEN-CUSTOM-ITEM-EVENT trigger of the form:

Declare
EventName VarChar2(32000);
Begin
EventName := :SYSTEM.Custom_Item_Event;
-- the event name contains all the event data starting with the event type like
-- keyPressed==>all the event data - for this make sure the variable used is long enough
-- you can later parse the data and use it accordingly:
-- here we put all in a text area to display it easily:
:block3.TEXT_AREA :=:block3.TEXT_AREA|| 'Event name: ' || EventName;
End;

Current event names start with the following names:

mouseReleased
mousePressed
mouseExited
mouseEntered
mouseClicked
mouseMoved
mouseDragged
focusGained
focusLost
insertUpdate
changedUpdate
keyTyped
keyPressed
keyReleased

If you want only specific events to be delivered you can set an event mask using the following method:

public void setCustomEventDispatchingMask(String eventMask) -This method allows only specified events to be dispatched once they have been enabled through the setEnableCustomEventDispatching. As argument can be specified a comma separated list of event names which are allowed to be dispatched to the  WHEN-CUSTOM-ITEM-EVENT. Example list of event names is as follows: "mouseReleased,insertUpdate,keyTyped" etc. By default all events are enabled through setEnableCustomEventDispatching.

hArgs:=FBEAN.CREATE_ARGLIST;
FBEAN.ADD_ARG(hArgs,'mouseReleased,insertUpdate,keyTyped');
FBean.Invoke('HTMLEDITOR_AREA',1,'setCustomEventDispatchingMask',hArgs);

The related methods for configuring the event dispatching are as follows:

public void setEnableCustomEventDispatching(boolean customEventsDispatchingEnabled) - this method allows to enable/disable dispatching of the events from the editor to the underlying form

public boolean isEnableCustomEventDispatching()  - this method returns whether is enabled/disabled dispatching of the events from the editor to the underlying form

public void dispatchOracleFormsEvent(String name, Object event) - this method allows to dispatch events from the editor to the underlying form which will captured into the WHEN-CUSTOM-ITEM-EVENT trigger of the form.

public void setCustomEventDispatchingMask(String eventMask) -This method allows only specified events to be dispatched once they have been enabled through the setEnableCustomEventDispatching. As argument can be specified a comma separated list of event names which are allowed to be dispatched to the  WHEN-CUSTOM-ITEM-EVENT. Example list of event names is as follows: "mouseReleased,insertUpdate,keyTyped" etc. By default all events are enabled through setEnableCustomEventDispatching.
 
public void resetCustomEventDispatchingMask() - will reset the dispatching event mask.

public void setEnableActionEventMaskForUIItems(String uiItemNames,boolean discardDefaultActions)- this method allows to be captured only specific action events from all UI elements such as toolbars and menus. discardDefaultActions specifies whether the default action for the UI element to be suppressed or not. This way you can implement easily your own handlers for all UI items of the editor by disabling the default functionality and implementing a new one.

public void addKeyToKeyEventMask(int keyCode, boolean shiftDown, boolean altDown, boolean ctrlDown, boolean metaDown, boolean altGraphDown) - If key is added to the key event mask only events generated from this key will be dispatched as custom events, others will be ignored . To reset the event mask use resetKeyEventMask method. keyCode is the code of the key on the keyboard. Example Enter is 13, Space bar is 32 etc.

public void resetKeyEventMask() -To reset the event mask use resetKeyEventMask method

So if you want to set key event mask for the F9, Shift+F9 and F10 you will need to do like this:

htmlEditor.addKeyToKeyEventMask(120,false,false,false,false,false);
htmlEditor.addKeyToKeyEventMask(120,true,false,false,false,false);
htmlEditor.addKeyToKeyEventMask(121,false,false,false,false,false);

 

9. General tips for integration with Oracle Forms?

Keep in mind that the mapping of String objects in Oracle Forms is to Varchar2 - it does not allow transfers with beans greater than 4096 chars. That's why we have provided to our Oracle customers the following methods as a workaround in order to retrieve or set the content in smaller chunks. You may use this approach for handling of content with unlimited length and adapt the following java code for use in OracleForms as demonstrated with the examples for invoking methods above.

Insert operations

public void openContentBuffer()

public void appendContentToContentBuffer(String content)

public void closeBufferAndInsert()

Retrieve operations

public int getBodyContentLenght() or public int getBodyContentLength() for bodyContent only

public int getContentLenght() or public int getContentLength() for entire content

public String getBodyContentPortion(int offset, int length) for bodyContent only

public String getContentPortion(int offset, int length) for entire content


Sample code:

Here we insert some content:
--------------------------------------
htmlEditor.openContentBuffer();
htmlEditor.appendContentToContentBuffer("This is ");
htmlEditor.appendContentToContentBuffer("some sample content");
htmlEditor.appendContentToContentBuffer(" long engouh to be tested...");

Close the buffer and insert it in the editor
--------------------------------------
htmlEditor.closeBufferAndInsert();


Retrieve the content in small pieces
---------------------------------------
int length=htmlEditor.getBodyContentLenght();
int portionLength=5;
int i=0;
while(i+portionLength<length)
{
System.out.println(htmlEditor.getBodyContentPortion(i,portionLength<length-i?portionLength:length-i));
i=i+portionLength;
}
 

10.Various customization features for Oracle Forms integration for loading translation files, dictionaries, single line spacing etc.

For the limited headings  use the following new methods:

Declare
hArgs FBEAN.ARGLIST;
Begin
hArgs:=FBEAN.CREATE_ARGLIST;
FBEAN.ADD_ARG(hArgs,'Normal,Heading 1,Heading 2');
FBean.Invoke('HTMLEDITOR_AREA',1,'setRestrictedHeadingList',hArgs);

-------------------------
For the limited fonts use the following new methods:

Declare
hArgs FBEAN.ARGLIST;
Begin
hArgs:=FBEAN.CREATE_ARGLIST;
FBEAN.ADD_ARG(hArgs,'arial,sans-serif,verdana,sans-serif');
FBean.Invoke('HTMLEDITOR_AREA',1,'setRestrictedFontList',hArgs);

-------------------------
For the limited font sizes use the following new methods:

Declare
hArgs FBEAN.ARGLIST;
Begin
