Getting java.lang.NoClassDefFoundError

[jamz2010]

Hi all,

I am currently getting the java.lang.NoClassDefFoundError when I try
and run my Google Wave Robot. I have checked and I have defiantly
copied the jar to /war/WEBINF/lib and included this in my build path:

package srp;

import java.io.IOException;
import javax.servlet.http.*;
import com.google.wave.api.*;
import srpProject.GoogleWaveWSServiceLocator;
import srpProject.GoogleWaveWSPortBindingStub;

public class SRPProjectServlet extends AbstractRobotServlet {
private int theState = 0;

@Override
public void processEvents(RobotMessageBundle bundle) {
Wavelet wavelet = bundle.getWavelet();

if (bundle.wasSelfAdded()) {
Blip blip = wavelet.appendBlip();
TextView textView = blip.getDocument();
textView.append("I'm alive!");
}

for (Event e: bundle.getEvents()) {
if (e.getType() == EventType.WAVELET_PARTICIPANTS_CHANGED) {
Blip blip = wavelet.appendBlip();
TextView textView = blip.getDocument();
textView.append("Hi, everybody!");
} else if (e.getType() == EventType.BLIP_SUBMITTED) {
String sResponse = "";
String sXML = "";
String sLastBlip = e.getBlip().getDocument().getText();

Blip blip = wavelet.appendBlip();
TextView textView = blip.getDocument();

try {
GoogleWaveWSPortBindingStub stub = new
GoogleWaveWSPortBindingStub();
textView.append("HI");
} catch (Exception ex) {
textView.append(ex.getMessage());
}
}
}
}
}

The import works ok but the error comes when it tries to create a new
instance of the GoogleWaveWSPortBindingStub. Does anyone have any
ideas on what I have dont wrong? I'm pretty sure I haven't included
the jar correctly but I cant see what I have done wrong.

Thanks

James

Hi James,

I came across the same problem but the solution was simple:
Check, if you are currentliy running the newest version of your app.

At the top left of your app engine account/dashboard there is
"Application: <yourApplicationName>" and next to it there is a
dropdown menu with your versions (or under Administration > Versions).
If you uploaded a new version, your engine did not start using the
newest. You have to tell your engine what version you want to be
online.

Hope this helps ... did I read the tutorial too fast or didn't anyone
tell me that new versions are not automatically set? (still, good
feature NOT using the lastest as greatest)
