Forms12c Frm-42431 Unable to Initialize Debugger Debugger Error

Question

Version Information Weblogic 12.2.1.3, Forms [64 Bit] Version 12.2.1.3.0

I have installed Forms Builder only on my machine. I follow the proper configuration steps to configure the forms. Full installation of WebLogic on a separate server.

When I am trying to run a module through the form developer's debug push button it shows the below message

"Frm-42431 Unable to Initialize Debugger"

I made the change in formsweb.cfg allow_debug=true, and also debugger.jar is included in class path in default.env.

Help is also not working. When I try to open the help system. The below message is open. FRM-18105: Failed to start the help system.

Please help me find out the solution for this problem.

You need to make sure your local environment variable(FORMS_BUILDER_CLASSPATH) is the same as what is in the registry editor(check under KEY_OracleHome1). If not the same or you don't find it in the local environment variables just do this:

Open Registry Editor -> computer -> HKEY_LOCAL_MACHINES -> Software -> Oracle -> KEY_OracleHome1

Look for FORMS_BUILDER_CLASSPATH right-click -> modify -> Copy all under value data Paste it into the notepad and look for ORACLE HOME under FORMS_BUILDER_CLASSPATH do the same copy all under value data textbox that the path of your files.

Then go back to your note pad replace all '%ORACLE_HOME%' with the path you copied on oracle home.

It should look like this after replacing all :

C:\Oracle\Middleware\Oracle_Home\jlib\frmbld.jar;C:\Oracle\Middleware\Oracle_Home\jlib\importer.jar;C:\Oracle\Middleware\Oracle_Home\jlib\debugger.jar;C:\Oracle\Middleware\Oracle_Home\jlib\utj.jar;C:\Oracle\Middleware\Oracle_Home\oracle_common\jlib\ewt3.jar;C:\Oracle\Middleware\Oracle_Home\oracle_common\modules\oracle.bali.share\share.jar;C:\Oracle\Middleware\Oracle_Home\jlib\dfc.jar;C:\Oracle\Middleware\Oracle_Home\oracle_common\modules\oracle.help\ohj.jar;C:\Oracle\Middleware\Oracle_Home\oracle_common\modules\oracle.help\help-share.jar;C:\Oracle\Middleware\Oracle_Home\oracle_common\modules\oracle.help\oracle_ice.jar;C:\Oracle\Middleware\Oracle_Home\oracle_common\modules\oracle.bali.jewt\jewt4.jar;C:\Oracle\Middleware\Oracle_Home\forms\java\frmwebutil.jar;C:\Oracle\Middleware\Oracle_Home\forms\java\frmall.jar;C:\Oracle\Middleware\Oracle_Home\forms\java\frmwebsocketjsi.jar

Then go to environments variable under system variable click new then variable name add FORMS_BUILDER_CLASSPATH on value add all text you copied on note pad after replace.

Close and Open forms again it should work now.
