java.lang.NoClassDefFoundError: org/apache/xerces/framework/XMLParser

I have a problem with my application. When I build the ear file everything seems to be ok. Deploying to JBOSS 3.0.7 run fine too. But when I call a method which creates a PCML object the program crashes.

Here's the source:

     // Create and instantiate an AS/400 Object
       // If you do not enter a user id or password, you will be prompted for each
       AS400 sys = new  AS400("10.0.0.XXX", "USER", "PASSWORD");
       System.out.println("\n\nConnecting to iSeries..."+"\nConnected to system: "+sys.getSystemName()+"\nRunning version: "+sys.getVersion()+"\nSigned on as user: "+sys.getUserId());

       // Create Data Objects
       ProgramCallDocument pcml;                // com.ibm.as400.data.ProgramCallDocument
       String parm1;                            // RPG program variable
       String comment;                          // RPG program variable
       boolean rc = false;                      // Return code for program call
       String msgId, msgText;                   // Messages returned from AS/400

       System.out.println("\n\nData objects created...");
       
       try
       {

            // Instantiate the Objects (assign the variables)
            pcml = new ProgramCallDocument(sys, "com.dcs.lims.central_order_management.ejb.testpgm"); /* CRASHES on this line */
           
            System.out.println("\n\nPCML object created...");
           
            pcml.setValue("program.parameter1", new String("5"));
           
            System.out.println("\n\nPCML values are set...");

etc.......

This is the error output generated:

I just don't get the problem, I have a JAR file in my classpath containing this class. I'm really running out of options here, so your help would be appreciated. I really need to fix this PCML problem.

Thanks in advance!

The xerces.jar needs to be in your classpath.  Try putting it in WEB-INF/lib directory for your app.

hackwarAuthor Commented:
I've tried that but still no luck. Jboss tells me the xerces.jar file is deployed but when I start the JSP which calls the bean that should call the PCML program, it gives the exact same error.

DaveyEssCommented:
Have you put a reference to xerces.jar in the manifest file in your jar?

I'm at a loss.  Is the PCML program running in the same VM as JBoss?  You are using Tomcat right?

hackwarAuthor Commented:
I have added it to the manifest still no luck.

Yes I use TomCat and Jboss. I develop and test on the same machine, so jBoss is on the same machine as my compiler.

TimYatesCommented:
Where EXACTLY are you putting the xerces.jar?

If JBoss says it is deploying it, it sounds like it is in the wrong place :-(

For webapps, you need to put it in WEB-INF/lib

For JBoss, you need to put it in jboss/server/default/lib

Adding xerces.jar to jboss/server/default/lib seemed to solve the NoClassDef error, but now a new one arose:

check you don't have multiple versions of xerces.jar in your project, WEB-INF/lib, or the jboss lib directories...

hackwarAuthor Commented:
nope only in the jBoss directories there is only 1 xerces.jar, I not quite sure what to do next.

TimYatesCommented:
Ahhhhh...right, you are using a library which has the class:

   com.ibm.as400.data.PcmlSAXParser

in it.

This class uses a different version of Xerces to what you have put into the lib directory :-/

According to this: http://www-912.ibm.com/s_dir/slkbase.NSF/0/4f33cee6f1cca16e86256e550080118f?OpenDocument

You need "xerces321.jar or later"

This seems to be the same error, and *may* shed some light on things if that first thing fails...

If I use any other (new version) xerces jar file the NoClassDef error re-appears. Maybe I should rebuild the new version into a xerces.jar file instead of a xercesImpl.jar

Ok, try putting the new version into WEB-INF/lib

and the other one into default/lib

and cross your fingers ;-)

TimYatesCommented:
Sorry, I mean...put the one which gets rid of the class cast exception into

jboss/server/default/lib

and the new version for Pcml in WEB-INF/lib for your webapp...

THEN, cross your fingers ;-)

Nope the verify error comes up again. Anymore suggestions? (thanks for your help so far!)

Ahhhh....the Pcml stuff is in your EJB layer?

I'm confused! ;-)  Too many jars in too many places :-(

What happens if you swap the jars round?

classcastexception fixing jar -> WEB-INF/lib
newxerces -> default/lib

?

Sorry...a bit hit and miss this answer...  But I'm running out of ideas :-(

Which I hope can shed some light on things :-(

After moving and deleting jars around I now finally get a 'normal' error from java.

org.apache.jasper.JasperException: RuntimeException; nested exception is:
      java.util.MissingResourceException: PCML document source 'com.dcs.lims.central_order_management.ejb.testpgm.pcml' cannot be found.

That's something I can work with!

Many thanks for all your help!
