this.transportBinding.call(this.stubConfiguration,this.globalProtocols,_getOperationProtocols("filterCompany"));

Did you check the defaultStackTrace.trc file for the error stack trace?

[Former Member · Accepted solution]

No, but there the file defaultStackTrace.trc is ?

Check the following path in your server:

If you are using NW04s: :\usr\sap\<InstanceName>\JC00\j2ee\cluster\server0\log\

If you are using CE: :\usr\sap\<InstanceName>\J00\j2ee\cluster\server0\log.

If you are using CE: [Log Viewing with the SAP MC|http://help.sap.com/saphelp_nwce10/helpdata/en/44/f71b59e38e2462e10000000a1553f7/content.htm]

Thank you for assistance. All works now. Problem was in classpath issues. I used one version of webservices_lib.jar for development but another version was running on the server.
