SAP Java Connectivity Builder -NoClassDefFoundError com.sap.aii...Reference

Question

Hi there,
I'm trying to generate Java Proxies for SAPJCO using the SAP Java Connectivity Builder (JCB). I got it from the NetWeaver 6.20 Release. The tool installs and runs properly but after putting in the connection properties and klicking "next", the application hangs. When activating System output, I get the error shown below.
I already tried to put all jar files contained in the C:\JBuilder5\lib\ext directiry into the classpath (but none of them contains the class mentioned).
Which is the right (standalone) tool for generating Java Proxies for a standalone Java application?
If it is JCB, is there a bug on the version I use (NetWeaver Release 6.20)?
Any help would be apreciated.

Hi,
>> Error :- java.lang.NoClassDefFoundError: com/sap/aii/security/proxy/KeystoreHelp
1) Can you check the class path  you have mentioned  is correctly
2) Setting of the Java in your system ( Desk top /Lap top ) check the Proxy settings
3) Re start the J2EE engine in the server
