500 Servlet Exception in Integrate Birt 3.7.2 runtime in Vaadin App

Xuechang

Hi there,

We have a Vaadin application in Eclipse running on Linux machine and is working (using Java 1.6).

I installed the Birt runtime 3.7.2 under /home and setup the BIRT_HOME in .bash_profile.
In Eclipse application, I add all jar files from ReportEngine/lib into Libraries tab in Build Path of this application. I added couple of lines in a Java file as follows:

I import several packages,

import org.eclipse.birt.core.framework.Platform;
import org.eclipse.birt.report.engine.api.EngineConfig;
import org.eclipse.birt.report.engine.api.EngineConstants;
import org.eclipse.birt.report.engine.api.EngineException;

in the program, I just add foloowing codes in the constructor:

//Add Testing BIRT Report Engine section
EngineConfig config = new EngineConfig();

try {
Platform.startup(config);

} catch (Exception e) {
e.printStackTrace();
}


When I run the application on Resin web server, I got 500 Servlet Exception as follows:

java.lang.ClassNotFoundException: org.eclipse.birt.core.framework.PlatformConfig
in EnvironmentClassLoader[web-app:production/webapp/default/Projex4]

I am not sure where can I find the package and should it in the runtime liberary?
Thanks!

Can you try removing this:
BIRT_HOME in .bash_profile.

Does the generated app have all the birt jars in the web-inf/lib?
