Interesting problem deploying a portlet

[Joe Sulewski <jo...@cobre.com>]

Hello,

I'm new to jetspeed so please bare with me. I created and successfully 
deployed the sample HelloPortlet example from the documentation. I added 
it to my classpath and everything worked fine. But when I try to change 
it by making it create a class in my classpath I get the following text 
in my portlet:

org.apache.turbine.util.TurbineException: Error rendering Velocity 
template: /controls/html/jetspeed.vm: Invocation of method 'getContent' 
in class mysite.com.portlets.MyPortlet threw exception class 
java.lang.NoClassDefFoundError

I'm running Tomcat 4.03 with Jdk1.3.1_03 on a Windows 2000 system. I 
didn't copy my class to jetspeeds web-inf/classes directory. Instead I 
jar'ed my classes into a jar file and put the jar file in:

c:\jakarta-tomcat-4.0.3\webapps\jetspeed\WEB-INF\lib

I looked at the jar file with winzip and I see my .class files. And if I 
take the code that creates an instance of my own class out it works just 
fine. But the moment I create my own class, whamo! I get the above 
message. So my question is as follows, how do I make Jetspeed see my own 
classes.

Thanks for any help in this matter,
Joe

ps I did try copying my class directory structure to 
c:\jakarta-tomcat-4.0.3\webapps\jetspeed\WEB-INF\classes and removed my 
jar file from the lib and the same problem happened.

If it helps here is my code:
package mysite.com.portlets;

import org.apache.jetspeed.portal.portlets.AbstractPortlet;
import org.apache.turbine.util.RunData;
import org.apache.ecs.ConcreteElement;
import org.apache.ecs.StringElement;

/**

 * @author  administrator
 */
public class F1LivePortlet extends AbstractPortlet{
   
    public ConcreteElement getContent (RunData runData)
    {
        mysite.com.portlets.MyPortlet 
myPortlet=mysite.com.portlets.MyPortlet();
        //return (new StringElement(myPortlet.getContent());
        return (new StringElement ("Hello World"));
    }
}

<?xml version="1.0" encoding="UTF-8"?>
<registry>
    <portlet-entry name="MyPortlet" hidden="false" type="instance" 
application="false">
        <meta-info>
            <title>My Portlet</title>
            <description>Sample of my Portlet</description>
        </meta-info>
        <classname>mysite.com.portlets.MyPortlet</classname>
        <media-type ref="html"/>
    </portlet-entry>
</registry>

I figured out my problem. I was compiling with jdk1.4 and running with 
jdk1.3
