Hello,

I just wrote a hello world bundle project and published to the virgo tomcat web server. But when I browse http://localhost:8080/hello-world/remoting/helloService, I got a HTTP Status 500 with a exception report which indicate the server encountered a Class not found error. Then I call clexport main.HelloWorldImpl in Server Console, the console prints a report saying "class not found, package only".

I am a beginner, please help! The attachment is my project file.

The MANIFEST.MF contains:

Manifest-Version: 1.0
Class-Path: 
Bundle-Version: 1.0.0

Can you please change the Class-Path to "Bundle-ClassPath: ." or simply remove this header?

Can you try to switch the property "WABHeaders" to "defaulted".
It is located in <Virgo-Home>/repository/ext/org.eclipse.virgo.web.properties file.
Restart Virgo and redeploy the application.
Let me know whether this helps.

I just tried to change to property value to "defaulted", but this time, the other class not found exception threw:

Do you have in your Web-inf/lib folder, a jar file that provides "com.caucho.hessian.io"?

You have to have such jar file locally (in Web-inf/lib), or you have to have such bundle installed on the system and also an import package in the web application's manifest for the necessary package.

I have downloaded a hession-4.0.7.jar and placed it to the WEB-INF/lib folder in my project, redeploy it and restart virgo, but the problem still exists.

Can you tell us what is the output of the "clload" command - more information for command usage you can find here: http://wiki.eclipse.org/Virgo/FAQ#How_can_I_diagnose_class_loading_problems.3F

According to your opinions, I have added an hessian jar into the WEB-INF/lib folder in the project, the project has been re-exported as the following attachment for future investigation.

I have tried with recent virgo 3.5.0 release, but the problem still exists.
