NoClassDefFoundError after upgrading to Weblogic 8.1 sp2 to sp4

Question

Hi ,
I have stuck in a problem where my application is using jco.jar file for SAP integration to my java application.
I have a java class "BAPI_IncentiveReport" in which it calls "addClientPool" that is in JCO class in jco.jar file but it is giving NoClassDefFoundError after i upgraded my Weblogic server 8.1 sp2 to sp4.
I have jco.jar under /opt/mspd/domains/mspdapps/lib as well as  libjRFC11.jco,libjRFC12.jco and librfccm.so files there. I also tried by keeping them under my application WEB-INF/lib folder but it is giving me same error.
package com.mindspeed.incentiverpt;
import com.sap.mw.jco.*;
import java.util.*;
import java.io.*;
import com.mindspeed.Configuration;
public class BAPI_IncentiveReport
    private String rptId;
    private String aecode;
    private boolean submit= false;
    private static final String POOL_NAME=
        com.mindspeed.Configuration.get("sap_inckey");

public BAPI_IncentiveReport(String rptId, String aecode)
    super();
    this.aecode = aecode;
    this.rptId = rptId;
public EmployeeAttr[] getAeCodeNames()
    boolean retval= false;
    JCO.Client client= null;
    EmployeeAttr[] empnames= null;
    Hashtable empallData= new Hashtable();
    Hashtable aecodeData= new Hashtable();
    try
           /* This is the point where it is giving NoClassDefFoundError.Till here every thing is executing------>*/
             JCO.addClientPool(
            com.mindspeed.Configuration.get("sap_inckey"),
            Integer.parseInt(Configuration.get("sap_maxcon")),
            Configuration.get("sap_client"),
            Configuration.get("sap_incuser"),
            Configuration.get("sap_incpassword"),
            Configuration.get("sap_language"),
            Configuration.get("sap_host"),
            Configuration.get("sap_incsystemnumber"));
        String timeinterval= "99991231";
        IRepository repos=
            JCO.createRepository("ESSRepos", Configuration.get("sap_inckey"));
        client= JCO.getClient(Configuration.get("sap_inckey"));
        System.out.println("Sagar");
        System.out.println(rptId);
        System.out.println(aecode);
        IFunctionTemplate ftemplate= repos.getFunctionTemplate("ZRFC_GET_PID");
        JCO.Function function= new JCO.Function(ftemplate);
        JCO.ParameterList input= function.getImportParameterList();
        input.setValue(rptId, "RPT_ID");
        input.setValue(aecode, "AECODE");
        client.execute(function);
        JCO.ParameterList output= function.getExportParameterList();
        System.out.println(output);
        JCO.Table dirrpt= function.getTableParameterList().getTable("DIRRPT");
. and more code

I have the same problem - my data had better not be gone!  Why won't Apple address this problem?
