The wiki for Identity Manager 12.6 SP6 contains a lot of the same content as previous versions of IDM, even though JBoss 5.1.0 is no longer a supported application server. This is especially obvious as you descend into less-frequented corners of the documentation, such as the User Console branding guide.
The instructions for how to recompile the JSP files (a necessary step under JBoss) indicate that you should run the script compile_jsp.bat / compile_jsp.sh, which is in the JBoss bin directory (https://wiki.ca.com/display/CIM12606/Compile+the+CA+Identity+Manager+JSPs). However, that directory does not contain either of the mentioned scripts.
Is recompiling still necessary? If so, where are the scripts installed now?
