runtime error when creating a simple class in a java program [message #696778] Thu, 14 July 2011 16:00 Go to next message

I try to use java to create a simple class diagram. But I get some runtime error.
Here is the code:

Model myModel = UMLFactory.eINSTANCE.createModel();
//myModel.setName("MyFirstModel");
Class department = UMLFactory.eINSTANCE.createClass();
Property dept_name = UMLFactory.eINSTANCE.createProperty();

dept_name.setName("address");
dept_name.setType(department);

department.getOwnedAttributes().add(dept_name);

It seems the above setter methods dont work and neither does add. The error I got
is:

Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/uml2/common/util/CacheAdapter
at org.eclipse.uml2.uml.internal.impl.ElementImpl.getCacheAdapter(ElementImpl.java:714)
at org.eclipse.uml2.uml.internal.impl.ElementImpl.eNotificationRequired(ElementImpl.java:852)
at org.eclipse.uml2.uml.internal.impl.NamedElementImpl.setName(NamedElementImpl.java:263)
at MyUML.main(MyUML.java:17)


Thanks.

HI

Looks familiar. I suspect that you haven't replicated the Eclipse plugin
registrations for standalone usage.

You may find org.eclipse.ocl.uml.OCL.initialize(ResourceSet) helpful.

Hi, Ed,
I don't get your idea. Can you tell me what I should do in details. What I did
is to just create a Java Project and then add those jar files to the library since
I only want to play with the UML2's implemenation. Thanks.

In which jar is the CacheAdapter class and have you put it on your
classpath? I assume you've looked it
http://wiki.eclipse.org/MDT/UML2/FAQ too...

Ed,
Sorry, how do I know which jar has CacheAdapter? I tried to read the
FAQ but not quite understand it. I think Q. 6 might be relevant to my
problem but have no idea how to solve it. Thanks.

Ctrl-Shift-T can be very helpful for finding a class. You can use the
"Link with Editor" button in the project explorer to find out where that
file is located. I'll bet you can guess which jar it's in just from the
package name and looking at the bundle names...
