First of all I’d like to thank myloon for this guide, all I did was translating it to English and included a direct link to the files needed.
Files Needed
After downloading the above file, extract it and copy the contents of the debugger folder to BEA_WORKSHOP_HOMEworkshop_10.3workshop4WPeclipsepluginscom.m7.nitrox.debugger_3.5.100.200807251738 and the contents of the serverdef folder to BEA_WORKSHOP_HOMEworkshop_10.3workshop4WPeclipsepluginscom.m7.nitrox.serverdef_3.5.100.200807251738
Make sure to backup any file before replacement.
Now open the cmd and change to the directory BEA_WORKSHOP_HOMEworkshop_10.3 and run the following command
workshop.exe -clean
Now you can create dynamic web projects and add JSF 1.2 support to it with Apache Tomcat 6 as the run time server.
