[jdom-interest] JDOM & WebSphere???

Sun Jan 28 06:12:03 PST 2001

Guy,

Thanks again for your time.

Here is a better explanation of where we are at.  I wrote this up on Friday.

Mike

*Explanation*
We are trying to install JDOM and Xerces in VAJ 3.5.2.

Try 1
-----

1.We create a project for Xerces and import the Xerces source and let
VAJ take care of the compiling.

2.During this process we hava a problem with the org.w3.dom,
javax.xml.sax, javax.xml.sax.helpers since IBM XML4J already has these
classes.  The version of the XML4J is 2.0.1.5.  so, we go ahead and
create a 'version' for these three packages.  And then, we are fine
loading Xerces.

3.Next, we load the JDOM source code into a JDOM project and let VAJ do
all the compiling.  No problems here.

4.When we go run WTE, we find that JDOM does not work properly while the
same source code works fine using JBuilder test environment.

5. The JDOM code is executed within a session ejb.

5.When we return a org.jdom.Document object from the session ejb, we
notice that nothing is in the object and a java.lang.InternalError
exception gets thrown.

Try 2
-----

1.We delete the packages org.w3.dom, javax.xml.sax,
javax.xml.sax.helpers and 'version' them.  Then we load the source code
for Xerces into the IBM XML project.  This works fine.

2. We follow steps 3,4,5 from above and have the same results.

Questions
---------
1.  Can we use Xerces with WebSphere?
2.  Can we use JDOM with WebSphere?
3.  Could this be a bug with the WTE only?
4.  What are the recommended XML parsing API's for WebSphere?  Which ones 
are supported?
