Oracle 10g reports migration to Oracle 11g migration

Question

I have migrated oracle 10g reports to Oracle 11g reports and generated REP file. But when we execute REP file using RWRUN.EXE I am getting below error.
ERR REP-50125: rwbuilder.conf:java.lang.NullPointerException
ERR java.lang.NullPointerException
to avoid this I tried below work arround which was posted in "https://forums.oracle.com/forums/thread.jspa?threadID=2365028" URL. but not success.
1. Go to C:\Oracle\Middleware\asinst_1\config\FRComponent\frcommon\tools\admin
2. Make a backup of the file 'cauprefs.ora'
3. Open up the file in a text editor:
--In the file, look for:
Reports.PluggableDataSourceFactories =
("oracle.reports.plugin.datasource.xmlpds.XMLDataSourceFactory",
"oracle.reports.plugin.datasource.jdbcpds.JDBCDataSourceFactory",
"oracle.reports.plugin.datasource.textpds.TextDataSourceFactory")
--Replace the value to: Reports.PluggableDataSourceFactories = ()
4. Save the file and try running Reports Builder again. Data Model should open up without crashing.
Could you please help me to resolve this issue.

When I use rwrun.bat report is not invoking i use below command line. I am executing rwrun.bat from C:\Oracle\Middleware\asinst_1\config\reports\bin path.
rwrun.bat report="C:\Program Files\prnsrv\advices\01\bcacuchq.rep" userid=dbuserid/[email protected] desformat=pdf DESTYPE=file DESNAME="c:\temp\test.pdf" TRACEFILE="C:\TEMP\test.LOG" PRM_BRCH_CODE=781 PRM_PROD_CODE=BC PRM_PROD_REF_ID=BC11100142 PRM_ORDER_COL=DELIVERY_MODE PRM_CHQ_RPT=Y
