Debugger Source Lookup

Question

Hi,
I'm developing a simple application service in NW 7.0 SP12. This service should use an imported webservice created from a RFC. But in debug mode when it try to call the operation and I try to step into the method, an error window occure with the message:
The sore of the type
'com.sap.wspermt.extsrv.z__bapi__bupa__search.Z__BAPI_BUPA__SE
could not be shown as the type was not found.
Know anyone what is here the problem?
Thanks in advance,
Daniel

Answer 1

for point 2.:
the debugging process has shown that the localhome cannot be resolved when I try to inspect this variable. And when chosen as watch there's <error(s) during the evaluation>.
The error occures within this automatically generated method: Any clue about the localHome?
private Z__BAPI__BUPA__SEARCHLocal getZ__BAPI__BUPA__SEARCH() throws com.sap.caf.rt.exception.ServiceException {
        java.lang.String method = BuPaSearchServiceBean.JARM_REQUEST + ":" + "getZ__BAPI__BUPA__SEARCH()";
        java.lang.String jndiName = "localejbs/sap.com/wspermit/Z__BAPI__BUPA__SEARCH";
        java.lang.String user = sessionContext.getCallerPrincipal().getName();
         Z__BAPI__BUPA__SEARCHLocal local = null;
        com.sap.caf.rt.util.CAFPublicLogger.entering(user, JARM_REQUEST, method, location, com.sap.caf.rt.util.CAFPublicLogger.LEVEL_MEDIUM);
        try {
//Here the return value from getLocalHome is correct but is not committed to the localhome variable
            Z__BAPI__BUPA__SEARCHLocalHome localHome = (Z__BAPI__BUPA__SEARCHLocalHome) HomeFactory.getInstance().getLocalHome(jndiName);
            local = localHome.create();
        } catch (com.sap.caf.rt.exception.ServiceException se) {
             BuPaSearchServiceBean.location.catching(method, se);
            Object[] args = {jndiName};
            com.sap.caf.rt.util.CAFPublicLogger.categoryCAF.logThrowableT(com.sap.tc.logging.Severity.ERROR, location, method, "APPSRV_JNDI_LOOKUP_ERROR", args, se);
            BuPaSearchServiceBean.location.throwing(method, se);
            throw se;
        } catch (javax.ejb.CreateException e) {
             BuPaSearchServiceBean.location.catching(method, e);
            Object[] args = {method};
            com.sap.caf.rt.util.CAFPublicLogger.traceThrowableT(com.sap.tc.logging.Severity.DEBUG, location, method, "APPSRV_SIMPLE_ERROR", args, e);
            com.sap.caf.rt.exception.ServiceException se = new com.sap.caf.rt.exception.ServiceException(e);
            BuPaSearchServiceBean.location.throwing(method, se);
            throw se;
        } finally {
            com.sap.caf.rt.util.CAFPublicLogger.exiting(user, JARM_REQUEST, method, location, com.sap.caf.rt.util.CAFPublicLogger.LEVEL_MEDIUM);
        return local;
