After that restarting the tomcat everthing works fine again.
How should i resolve this problem.
Please help me.
What connection times out? What are you using your connection for?

If you're using a pool, sometimes the connections in it expire due to long periods of incativity. One workaround is to always fetch some metadata from connection prior to doing any serious work. If metadata retrieval fails, get another connection from the pool, and so on. Make a resonable number of retries, depending on the pool size, before notifying the user that something is wrong. Please come back and tell us what solved the issue.
