    Custom classpath and custom jar entry in R12

    L S P..
      Hi all,

      I have created the custom classpath and custom jar file for isrore process. I had put custom jar and custom class entry in orien_application.xml file. But it was working on R12 at doveloper mode. It will creates the classes for custom jsp file using custom import class or custom jar. But once i revert back the devloper mode means it won't work.
      Could you please help..

          Oracle apps R12 - Compiling JSP with custom classpath
          We all know that to compile JSP manually on the Oracle Application R12 instance, we need to run the file $FND_TOP/patch/115/bin/ojspCompile.pl.

          Its help is as follows:

          syntax: ./ojspCompile.pl COMMAND {ARGS}
          COMMAND --compile               update dependency, compile delta
          --create                rebuild entire dependency file
          -delta.out update dependency, list delta to file
          -dep.out update dependency, output heirarchy to file

          ARGS -s matching condition for JSPs filenames
          -p number of parallel compilations
          -log to override logfile from ojspCompile.conf
          You are
          recommended to set the log file location
          outside of any network file system shared (NFS) area/drive.
          -conf to override ojspCompile.conf
          --retry         retry previously failed compilation attempts
          --flush         forces recompilation of all parent JSPs
          --quiet         do not provide an actively running progress meter
          --fast          instantly fail jsps that are possibly invalid

          example1: ojspCompile.pl compile -s 'jtf%' -p 20 retry
          example2: ojspCompile.pl compile -s 'jtflogin.jsp,jtfavald.jsp' flush
          example3: ojspCompile.pl compile fast --quiet

          If your JSP uses custom classes, then compiling jsp manually can fail if proper classpath is not set. Yes, even though if you have setup the classpath correctly in orion-application.xml, it will fail because this jsp compile utility does not read orion-application.xml classpath.

          So, the problem is to identify where to set the classpath so that above utility can pick it up. After several search and looking into code, I found following:

          By default, the jsp compiler script uses following configuration file
          $INST_TOP/appl/admin/ojspCompile.conf
          This conf file has a classpath field in it which is usually pointed to file
          $INST_TOP/appl/admin/ojspCompile.properties
          This property file lists the classpath used for JSP compilation.

          So if your classes are not listed in this file, your jsps will not compile by ojspCompile.

          Ofcourse, you can always set the "main_mode" to "recompile" in orion-web.xml, but that for production you do not want to change it and compile the JSP on file deployment.
