Java EE (Java Enterprise Edition) General Discussion

I am evaluating two JMS APIs: The free one comes with J2sdkee 1.3.1 and the iPlanet Message Queue for Java 2.0 (free for development and evaluation, not free on Production environment).

I created two JSP pages running under Tomcat 3.3. One JSP page is calling a Java class 1 which uses j2sdkee1.3.1 JMS API: it creates InitialContext() and lookups for QueueConnectionFactory & Queue, then sends a text message to the Queue.
I did a little performance improvement by putting this process into a static method init(), so it will be called only once. The latter request will only send message.

The second JSP page is calling a Java class 2 which doesn't use JNDI, instead, it calls the new QueueConnectionFactory/QueueConnection classes provided by iPlanet MQ API.

I found out that InitialContext() call and lookup process is taking quite a long time in the first case. After that, sending message is quite fast. However, if "j2ee" is shutdown in the middle, the JSP page can't recover unless I restarted Tomcat server.

The performance of iPlanet MQ API is pretty good even if the QueueConnectionFactory/QueueConnection classes are created for each request. And it can recover after the Broker is restarted.

Anybody experienced in using J2sdkee1.3.1 JMS API? If you know a better way to improve performance other than the static method init() which can't recover, please share your information. Appreciate it.

Thanks,
Ye
