Please find the below code snippet where Iam adding the contents to the model file .I having two ways to add the contents:
1st way:

final ResourceSet resSet = new ResourceSetImpl();

resSet.getPackageRegistry().put(ePackage.getNsURI(), ePackage);
Resource resourcee = resSet.createResource(local_semanticModelURI);
resourcee.getContents().add(au);

// now save the content.
try {
resourcee.save(Collections.EMPTY_MAP);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
while adding the elements it doest give an error.If we close and open project then Iam getting the below error
!MESSAGE An internal error occurred during: "Loading models".

2nd way:

final ResourceSet resSet = new ResourceSetImpl();
Resource resourcee = resSet.createResource(local_semanticModelURI);
// Resource resourcee = resSet.getResource(local_semanticModelURI, true);
resourcee.getContents().add(au);
try {
resourcee.save(Collections.EMPTY_MAP);
// resourcee.load(Collections.EMPTY_MAP);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
It is working correct while closing and opening the project also it is working fine but the way it will write in text editor is XML format if (when we do open with text editor on modelFile) .I dont want to write in that format. If I follow first process it will write in the format I want so that I can export easily but while opening and closing of project Iam getting resource malformed URL exception.

can some please help me where Iam going wrong

Hi

"ar" and "de" are presumably related in some way to the value of local_semanticModelURI that you don't share with us.

When I get a MalformedURLException, I use a debugger and usually find out quite rapidly how stupid I have been.
