The thing is, I already have the EJB working and a number of different apps already connect and use them. I would also like to be able to use them through my servlets running in a tomcat cluster (then I could move most of my stuff to tomcat), but I really do not have the time to rewrite everything.

The j2ee.jar contains a servlet.class that conflicts with the servlet.jar. I have tried "cutting" out portions of the j2ee.jar that interferes with the servlet.class but then I get exceptions from other parts tring to access servlet.class. I have also tired (suggested by Mark Thomas) removing the servlet-api.jar and jsp-api.jar from tomcat and using the j2ee.jar but that did not work either. The other apps are running on Sun's Application Server (the same kind of server as the EJB's use but not the same server) or Swing/console based apps. I just wanted to use a cluster of Tomcat servers for this project. If Sun wants to really push the J2EE standard, it would seem they should have some standard way to access the services (like EJB's) so we do not have these imcompatibilities.

Sure, EJBs are designed to be used from servlets, but they can't really leave their containers (as you have found). Since you need j2ee.jar available to support the EJBs, there are all kinds of problems because of the incompatibilities between libraries (servlet.jar and j2ee.jar, for example). > This way you only have to set up the logic once (in an EJB) and then > any application (servlet, swing, jsp....) should be able to access it. True. Although the remote application doesn't "host" the actual bean (i.e. the real data lives on the EJB server), you still need the endpoint portion of the bean to be supported by the EJB framework. Perhaps I'm confusing the issues; of course EJBs should be able to be used by, say, a client-side application that is not running within a formal container (JBoss, websphere, etc.) I think the problem is the incompatibilities between j2ee.jar and servlet.jar. It may be possible to lobotomize Tomcat in order to get it to do this, but perhaps it's not worth the trouble. What about using another app server? > That is the theory anyway, but it does not seem to be working with > tomcat because I can access the EJB through console, swing, and most > web based apps except for the ones on my Tomcat cluster :O(. Those other webapps are running on something: what is it? -chris --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
