    While deploying war I got an error message during compiling:

    Error: java.lang.NullPointerException

    I'm using JDeveloper 9.1 with Java 1.3.
    Anyone has a solve?
    Thanks in advance

      yawebmail will not compile with Java 1.3 (see\).

      If you post Exceptions, please post a stacktrace, too.

      ok, I've moved yawebmail to Jdev10 and it worked fine. But today I got an error messages for each jsp which uses cuic.tld:
      Error(109): Internal error, ClassNotFound creating tag parser for cuic:outputPerFolderLevel, class: null

      Where I have to copy those tld files to make yawebmail to work again.

      I tried to deploy .war under the Tomcat 5.5 and found exception that solved by adding the following line into web.xml:

      it may be useful for someone.

      I've translated yawebmail into Serbian and will send you a copy.

      Thanks a lot,
