Infrastructure Software

Hi,
I am not able to coonect to a server using the using the below code.

If i try the same code on the server to connect it self, it is working fine. But when i try to connect from other server it give the below error. And i am using the IBM Jdk while getting this error. Is there some setting to avoid this error.

Error:
