    JBoss, Tomcat, EJBs and XML

    Mr Bo Newbie

      Hello,

      I am relatively new to web development using the Java Enterprise framework. I have used Java a lot, as well as a bit of XML. However, I am having some problems getting my web application up and running using JBoss and Tomcat.

      I have a session EJB that generates XML from an entity EJB. The idea is for the session bean to return a DOM document constructed from the data within the entity bean.

      The problem occurs when the session bean tries to return the DOM document to the calling JSP. I get an exception which I think is a result of the DOM object not being serializable. I have read that using the Xerces parser rather than Crimson fixes this problem. Is that true, is it a good idea to switch, and how do I go about it?

      I am using the JBoss/Tomcat bundle. (JBoss-2.4.4_Tomcat-4.0.1)

      Thanks,
      MrBo.

          Hi,

          I had a problem that sounds similar to that one you described. Which xerces version do you use ? There is a bug in xerces 2 (beta), that makes it impossible to serialize a DOM - object. Switching to an older xerces version (I used 1.4) worked fine for me.

          Bye Tom
