I need to convert some BPEL-models using the BPELReader [message #10823]

Hello,

I have to convert some BPEL-models that are not based on EMF!
The Designer is able to open them, so I thought that I were able to use
the org.eclipse.bpel.model.resource.BPELReader to read them from my
bpel-model file and convert them to the emf-based bpel model.

But everytime I tried to access the BPELReader via a simple program
there is a NoClassDefFoundError.
Below I´ve attached my source and the error-message.

I need to convert the models very soon for my thesis.

Thanks

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import javax.xml.parsers.DocumentBuilderFactory;
import bin.org.eclipse.bpel.model.resource.BPELReader;

public class Main {
public static void main(String[] args) {
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
File file = new File("D:/SampleProcess.bpel");
FileInputStream stream = null;
try {
stream = new FileInputStream(file);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

System.out.println("test");
BPELReader reader = new BPELReader();
System.out.println(reader);
}
}

Are u running this code as part of an Eclipse plugin ? I think you do not.
I am not sure if that works if you are trying to access the bpel model
outside of eclipse - you'd have to export the bpel model plugin (and all
its dependencies and dependencies of dependencies) as jar files and put
them onto the classpath of your program - not sure this is feasible ?!

I suggest to create a eclipse plugin, add a dependency to bpel.model and
put that code inside of the plugin.
