Re: java.lang.NoClassDefFoundError is plaguing me

I've also had similar problems with compiling JSPs under TOMCAT. I think what's happening is that, since a JSP has to be compiled, TOMCAT runs javac. But javac obviously doesn't use the same custom class loader that Axis uses, so in order to make those jars visible to the compiler, they have to be in the classpath, or in a directory like common/lib where Tomcat can find them and add them to the classpath.

While its not a permanent or architecurally satisfactory solution ... have you tried copying jdom.jar to the Tomcat/common/lib directory ?

I fixed a similar problem this way.

Subject: java.lang.NoClassDefFoundError is plaguing me

I have been struggling w/ this for a few days, and have been to the
archives and back, and haven't found a solution.  Perhaps someone here has
run into this problem and can point out to me where I went wrong.

I am using tomcat 4.1.12 as my server, and i have placed axis 1.0 under the
webapps folder, like so...

webapps
    axis
        WEB-INF
              classes
              lib

In the lib directory I placed all the jar files that my service is reliant
upon.  However...when I execute a service from a jsp, I find errors telling
me that objects that I placed in the lib directory can't be found.

The only way I have solved it is to place the specific jars in the
classpath, but that defeats the purpose of this architecture.


The specific jar that I'm struggling w/ at the moment is the jdom.jar.  I
created a simple jsp page where I create a jdom Document, just as a sanity
check that the webapp can see it, and that goes fine....  Then I execute
the soap service, and I get an error telling me that org/jdom/Document
cannot be found.

Here is a copy of the test code I am using, in case it helps solve the
problem, and I will aslo provide a snippet of the error.


<%        Object ret=null;
         try {
            try{
                     org.jdom.Document doc = new Document();
                     System.out.println( "**************  " + doc.getClass
().getName() + "  **************" );
              }
              catch(Exception e){System.out.println("Can't print the
document " + e.toString());}
             //String endpoint
="http://localhost:8080/axis/services/CTPortal";;
             String endpoint
="http://localhost:8080/axis/services/CTPortal";;

            Service  service = new Service();
            Call     call    = (Call) service.createCall();

            call.setTargetEndpointAddress( new java.net.URL(endpoint) );
            call.setOperationName( "login" );

            ret = call.invoke( new Object[] { "0", "ctrd", new Integer(92)
} );
            System.out.println(ret.getClass().getName());
            System.out.println("Sent 'Hello!', got '" + ret + "'");
        } catch (Exception e) {
            //e.printStackTrace();
            System.out.println("Damn Dirty Error");
        }
%>



The error:
