Problem using Resource given a emf model [message #397996] Mon, 23 January 2006 06:25 Go to next message

Hello all,
I have generated a emf model giving a XML schema as input. Then i
generated classes for the model. Now i want to create a XML instance given
an xml file.

To do this, i used Resource api as follows:

Resource.Factory.Registry reg = Resource.Factory.Registry.INSTANCE;
Map m = reg.getExtensionToFactoryMap();
m.put("*", new XMIResourceFactoryImpl());
ResourceSet resSet=new ResourceSetImpl();
URI uriobj =
URI.createURI("file:/D:/projects/DAME_java/wspace/library/Lines.xml ");
Resource res = resSet.getResource(uriobj,true);
Object forum = res.getContents().get(0);

This code generates a "Package with uri 'null' not found." exception when
i execute the getResource method. I have checked up the net where the same
kind of code is used. I dont know whats happening. Could anybody help me
please.

Shruthi,

Have a look at the generated XyzExample.java in the *.tests plugin.
That will illustrate how to do this correctly.

Hello Mr Ed Merks,

I didnt find that xyzExample.java anywhere. Could you please paste lines
of that xyzExample.java in to the mail. Please dont attach the file
because last time when i had posted, the security system did not allow me
to open the file.
This code would be of very great help to me. I have still not found the
correct code.

Thank you very much for your reply.
Best Regards
Shruthi
