Error invoking 'set_xslt_locale':'java.lang.IllegalAccessError

Question

I am running seeded sourcing pages. I am getting following exception when i try to print an RFQ from JDeveloper:
Error invoking 'set_xslt_locale':'java.lang.IllegalAccessError: tried to access class oracle.apps.fnd.i18n.common.text.DigitList from class oracle.apps.fnd.i18n.common.text.ExcelNumberFormat'
Re: XML Publisher common user interface document viewer
In the above thread, i found below steps to resolve this:
Cause:
Essentially the problem is caused by incompatible versions of classes in the oracle.apps.fnd.i18n.* package held in the file jdevbin\jdev\appslibrt\aolj.jar versus the classes used by the BI Publisher libraries. The 'set_xslt_locale' method was introduced in BI publisher version 5.6.3 so if you have upgraded to this version on the server it is likely that you will get this error in JDeveloper.
Solution:
1) You will first need to copy the following file to your local JDev install and add it as a library via Project Settings --> Libraries :
$FND_TOP/java/3rdparty/stdalone/xdoparser.zip
2) Next fetch the latest version of the oracle.apps.fnd.i18n.* classes from $OA_JAVA. Create a zip file of these files (i.e. i18n.jar), copy to your local JDev install and add it as a library as you did with the xdoparser.zip.
3) Copying these files alone will not solve the problem because JDeveloper will use the oracle.apps.fnd.i18n.* classes located in the jdevbin\jdev\appslibrt\aolj.jar file before using the ones located in the file added in step 2 (i18n.jar). To get round this, ensure that the the library you have added for the i1n8.jar file is higher in the list (under Project Settings  Libraries) than the libraries “FND Libraries” & “OA Developer Libraries” (if selected). This will ensure that the files in i18n.jar are used prior to those in jdevbin\jdev\appslibrt\aolj.jar. If this does not work (some users have found this approach not to work), make a backup of the file jdevbin\jdev\appslibrt\aolj.jar and then manully remove all files in the oracle.apps.fnd.i18n package from the file.
4) In addition to the above copy the file $OA_HTML/xdo_doc_display.jsp to your local OA_HTML directory (usually jdevhome\jdev\myhtml). You should also set the temporary directory of the XML Publisher (under Admin) to a directory that exists on your PC (eg. /var/tmp on your PC will be c:\var\tmp).
I am new to Java/JDeveloper/OAF.
Can someone please help me with the above steps?
I am unable to post anything in OA Framework forum.

Answer 1

Yes, the OA Framework forum is "broken"
However, that is the best place to get help for this question.
