PB12.6 compatiblity with Oracle JRE 1.3.1_02

Question

Hello
I am currently using PB12.6 .
we need to call the Java bean through OLE connection. Java bean is built in JRE_1.3.1_02 version. Here is code
ctisActiveXName = 'Java Bean Class'
ioleServer = CREATE OLEObject
llResult = ioleServer.ConnectToNewObject (ctisActiveXName)
However PB12.6 get crashed at above line.
This code works fine in PB12.0 . Note that we cant change the Java component built in JRE_1.3.1_02.
How can I make it work in PB12.6?
Any help is highly appreciated.
Thanks

Hello Amol,
To simulate your problem, I used this excellent sample Wrap a Java bean in a COM object - Real's Java How-to to bundle a JavaBeans as an ActiveX object using the ActiveX Bridge technology
I had to install very old JDK 1.3.1_02 and Java Plugin 1.3.1 into my Windows 7 box
Here are my observations after coding below script (I also used excellent document http://scn.sap.com/community/developer-center/powerbuilder/blog/2014/09/24/how-to-capture-error-messages-from-an-activex-control from Roland Smith to create n_oleobject OLE object)
+ PowerBuilder 12.1 and 12.5.2 are working without any crashes
+ PowerBuilder 12.6 is crashing directly at line ConnectToNewObject
My real concern is that
* the COM object (which is in fact a Java object) is using an EOL JDK and EOL technology
* PB 12.6 is not compatible with this JDK
I'm not sure if we can support COM objects developped with obsolete technologies.
n_oleobject   objJava
string    strFromjava
integer   li_rc
objJava = CREATE n_oleobject
li_rc = objJava.ConnectToNewObject("JavaBeanSays.Bean")
If li_rc = 0 Then
   try     
  strFromJava = objJava.getHello()
  MessageBox("From PB via JavaCom", strFromJava)
  objJava.setHello("Bonjour le monde")
  strFromJava = objJava.getHello()
  MessageBox("From PB via JavaCom", strFromJava)
   catch ( RuntimeError rte )
      PopulateError(objJava.ErrorCode, objJava.ErrorText)
      MessageBox("OLE Runtime Error #" + &
            String(Error.Number), Error.Text, StopSign!)
      objJava.DisconnectObject()
      Return
   end try
   objJava.DisconnectObject()
Else
   MessageBox("OLE Connect Error #" + String(li_rc), &
         "Connect To Object Failed!", StopSign!)
End If
DESTROY objjava
Thanks
