Error with JSF application on SAP NetWeaver App Server 7.3

Question

Hello Gurus,
                         I have a JSF web application which I have deployed on the SAP NetWeaver Server 7.3 , but when trying to access the same I get the error
Cannot process an HTTP request to servlet [Faces Servlet] in [SecurePro] web application. [EXCEPTION] javax.servlet.ServletException: com.sap.engine.services.servlets_jsp.server.jsp.exceptions.CompilingException: Error in executing the compilation process: [ Compilation Failed! Exit Code=1
Has anybody else also got the same error earlier?, I am using Mojarra  implementation for JSF.
I had earlier deployed the same application in an earlier JSF version and it worked on NWAS7.0 but Now I need to upgrade that, Please help
Thanks

Hi Ingo,
Yes - Ive tried every possible combination and here is my findings...
I don't think the 32-bit version of the SAP Java Connector (2.1.8) works on a Windows 2003 x64 SAP J2EE 7.0, i.e. the sapjco.jar file. I created a directory and added it to the CLASSPATH of the J2EE server (server and instance) and I also added it to the Java classpath using: java -jar <path+sapjco.jar> -classpath. Executing this command brings up a SAP Java connector window where it displays information of the version, location of the sapjcorfc.dll file etc. This windows opens, but is not able to display the information. If I do exactly the same with the x64 bit version of the SAP Java connector (2.1.8) it displays the information correctly in the SAP Java connector popup. I've tried copying the sapjcorfc.dll and the librfc32.dll to both the /system32 and the SYSWOW64 directory on the server.
HOWEVER, in CMC the Role Import tab still does not work - I just get the text null (in red). Before adding the sapjco.jar to the java classpath I got another error on the Role import tab - something like /com/sap/mw/jco/$JCOFunction. So it seems like it is now able to find the sapjco.jar file, but can not use it properly.
The big question is now: Should the sapjco.jar file actually be on the Application server or on the BOE Server? I know it says on the application server in all documentation, but that generally assumes Tomcat and all installed on one server.
BOE uses the sapjco.jar file to connect to the BW system to import the roles and that must be the BOE server doing that job and not the Application server???
Just my thoughts - maybe we can discuss this at Teched in Phoenix? :o)
Best regards,
Jacob
