Hello Everyone

I am new field of Java and eclipse. Unfortunately I can not figure out a possible way of overwriting an existing resource file using Java. I want to override because I need to make some changes in the namespace of of transformed resource file (xml file) manually in the file and then perform the transformation again. Overwriting enables the transformed file to recognize correct namespace and I get a valid output.

I am using the following code

ExecutionDiagnostic result = executor.execute(context, input, output);

if(result.getSeverity() == Diagnostic.OK)
{
List<EObject> outObjects = output.getContents();

URI outputURI = URI.createURI("platform:/resource/artop-autosar".concat(inputmodel.replace(".uml", ".xml")));

Resource outResource = new ResourceSetImpl().getResource(outputURI,false);

outResource.getContents().addAll(outObjects);
try {
outResource.save(Collections.emptyMap());
System.out.println(inResource);
System.out.println(outResource);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();

}
but I get an exception of null pointer at "outResource.getContents().addAll(outObjects);"

If I am on a wrong forum please guide me. Ill appreciate your help.

Regards

For my output one possible solution is

Resource outResource = new ResourceSetImpl().createResource(outputURI);


but I dont want to create a resource. I want to add contents to an already existing resource.

Thanks

You're right. This is a Java question. My suggestions would be a)
javaranch.com or b) stackoverflow.com.

Actually, this was an Eclipse Platform related question. Ahsan, try
posting in the Platform forum group, found on the Forums Home page under
the heading "Eclipse Projects."

Thanks both

I managed to get the problem solved by referring to some already existing thread.
