Having problem loading resource file in WAR

Question

Forgive me to post it here, I'm not sure where I should post this question.
          I'm using weblogic 5.1 with sp 9. In an WAR file, I put an resource file
          myapp.dtd as the follwoing:
          WEB-INF/classes/myapp.dtd
          WEB-INF/classes/mypackage/MyHello.class
          In MyHello.java, I'm loading myapp.dtd using an absolute path:
          getClass().getResourceAsStream("/myapp.dtd")
          This fails and returns null.
          However, if I put myapp.dtd in the same directory as MyHello.class
          WEB-INF/classes/mypackage/myapp.dtd
          WEB-INF/classes/mypackage/MyHello.class
          and use a relative path:
          getClass().getResourceAsStream("myapp.dtd")
          This sucessfully load the resource file.
          Does anyone know the problem with the first approach? Thanks.

Answer 1

A correction, both approaches seem to fail if I deploy it in a WAR file.
          However, both of them succeeded if I deploy it as an exploded WAR file. So
          the problem is not absolute path v.s. relative path. It is a problem in
          weblogic class loader's handling of WAR file. I think this is clearly a bug
          in weblogic.
