Re: Does jBoss work on iSeries?

    Hi Ivan,

    As a followup, while no one can give really meaningful advice without
understanding your application, it begins to sound as if Tomcat or Jetty
with/without an HTTP server might meet your needs.  You still should
consider future usage; if you see a need in the future for the integrated
services I pointed out in my previous message, you might still opt for J2EE.

    Incidentally, most JDBC drivers now include a connection pooling
facility.  You are not going to get away from thread safety issues in
webapps whether under J2EE or not.  If your transaction management
requirements are purely for database operations, JDBC has it.  If your
transactions include non-DB operations, then you will need an overall
transaction manager, which is included in J2EE.  HTH,
