We have a application running on Weblogic. We have developed a Java class which gets a connection from the connection pool and have methods to get Statemet Objects on the connection. from the client code example: JSP we instansiate this class to get the Connection object and the Statement object and execute queries.
There seems to be a potential problem in the sense that there is Statment Contention. Exampele : 2 Statement Objects A & B are getting executed Statment B completes its operations but A is still open when we call the closeStatement method on Statement object B it seems to be closing Statemnt A which causes a lot of problems.

Could you please advice

Sounds like the handling of your Connection object isn't thread safe. Are you getting hold of the connection object in a servlet or JSP and holding onto it as a an instance variable? That would be the most obvious cause for your woes.
Did you want to give some more detail on your setup if this is not the case?
Don't get me started about those stupid light bulbs.
