JCO Error with CMC on SAP NetWeaver WebAS Java 7.0 Server

Question

Hi, all
We just installed our BO Enterprise XI 3.1 system, when we attempt to import SAP roles in the Central Management Console (CMC), the result is the following error: "An error occurred: com/sap/mw/jco/JCO$Function".
I have checked note 1274700 and 1292144, but in these two notes it use tomcat as the Java web application server to hold BO web applications like CMC. In our case, we use the SAP WebAS Java 7.0 Server.
Below is our system info:
Server 1: Windows 2003 SP2 32bit, Install BO Enterprise XI3.1, Crystal Reports 2008 and Business Objects Integration Kit for SAP. We did't choose install tomcat option.
Server 2: Windows 2003 SP2 x64, SAP NetWeaver WebAS Java 7.0 to run BO Web Applications.
Below is our whole installation process:
On Server1, Install BO Enterprise XI3.1, Crystal Reports 2008 and Business Objects Integration Kit for SAP. We choose "I will delpoy the web components after installation" option when install the BO Enterprise XI3.1 and Business Objects Integration Kit for SAP. We didn't choose the install tomcat option.
After the BOE XI3.1 and Business Objects Integration Kit for SAP installation, we user wdeploy tool to generate the ear files, copy the 19 web components ear files to Server2, manually deploy all the total 19 web components packages on our SAP NetWeaver WebAS Java 7.0 System on Server 2.
All the instalation processes above finished successfully.The web componnets are also successfully deployed on SAP NetWeaver WebAS Java 7.0 system.
When we start to configure the Business Objects Integration Kit for SAP, We logon to CMC, choose Authentication, double click SAP, fill info on tab "Entitled System" when we click tab "Role Import", we get the error info "com/sap/mw/jco/JCO$Function".
Then we download the SAPJCO 2.18 package 32bit for Server1, x64 version for Server2, and did following task on both Server1 and Server2:
1. Put the librfc.dll and jcorfc.dll file to C:\Windows:\System32
2. Add CLASSPATH, point to sapjco.jar file.
But still don't work.
Does anyone use the SAP NetWeaver WebAS as the web application server for BO?
Also I want to know does SAP officially support tomcat for production use now? I mean if some web error occurs about tomcat, will SAP support it?
Please advise.
Thanks,
Daniel

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,
