HI Gopal,

This thing should not be happend. As it is giving null pointer exception for standerd libraries..

service:jmsconnector

library:jsse

library:servlet

common:library:IAIKSecurity;library:activation;library:mail;library:tc_secssl

library:ejb20

library:j2eeca

library:jms

library:opensql..

solution is add them into library refrences.

1. check all these libraries are available on server.

2. note their locations.

if they are available then

3. right click on project.

4. in prefernces. add there library refrences as.

sap.com/ejb20.

sap.com/IAIKSecurity..
