create package in a eclipse plugin [message #476646]

Hi,

I'm writing a eclipse plugin,which will create some uml models by using
UML2.

I wrote following code in the plugin and call it

public void run(IAction action)
{
...
// create uml package

org.eclipse.uml2.uml.Package
paket=org.eclipse.uml2.uml.UMLFactory.eINSTANCE.createPackag e();
paket.setName("package");

// export uml model
...
}

The plugin returned without giving any answers or error message to me. So
I set one breakpoints on each line and step into. On the first line, in
which the package should be created, it went to the EventTable and sent
some event to Workbench. Then it went to an exception in the runEventLoop
: "java.lang.NoClassDefFoundError: org/eclipse/uml2/uml/UMLFactory". I
step out and resumed. It stopped on the first line and returned.

The code works very well when I put them in a single main method.

Is there something I've missed? I am new to Plugin.

plugin dependencies?
