Copy the registry.dat file from oracle 10g (registry.dat located in where you installed your developer suite like C:\DevSuite\forms\java\oracle\forms\registry\registry.dat ) and replace it in 11g developer suite where you installed.
Hope this will help
Thanks for responding
I copied that file but it did not work.
In the formsweb.cfg the parameter imageBase=codebase.
In the old registry.dat file the default.icons.iconpath is blank and this did not work. I added the path where the icons jar file is kept to this parameter - still the same errors.
Worth noting our old forms version was 9.0.4 not 10g.
Have you restarted the instance after replacing registry.dat file?
If no means then do it.
If problem persists let me know...
I put the path of our jar files into the parameter in registry.dat and restarted the application on the app server. Parameter specified as follows:
A jar file called images.jar contains the gif files.
Unfortunately still get the same issue.
