WebSphere and WebLogic both provide application servers that comply to the J2EE standard. Just like Toyota and Ford create cars that comply to Highway Safety standards. You can deploy J2EE applications to both servers.
But they compete on scalability, robustness, ease of integration, extra features, price, reliability, and any other point you want to compete on. And there are many vendors in the J2EE space, not just WebSphere and WebLogic, although I do believe they are the two biggest players.
