Hii

can anyone Please help me how to add resources to a resource set programatically in sirius.My resource set is already having rootobject.How I need to add resources to that existing resource set.

Iam having the following code snippet which works fine
final ResourceSet local_rs = new ResourceSetImpl();
final Resource local_resource = local_rs.
createResource(local_semanticModelURI);
global_domain.getCommandStack().execute(new RecordingCommand(global_domain) {

@Override
protected void doExecute() {
/* adding the contents of arEobject to resource */
local_res.getContents().add(global_autosarobj);
try {

//local_createdSession.save(local_monitor);
local_res.save(Collections.EMPTY_MAP);

} /*End of try*/
catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}/*End of catch*/

}/* End of doExecute() */
});
this works fine for some cases for some cases it is showing error I feel iam doing something wrong

Iam thinking that I was not supposed to create a newResource set.
how to add resources to that existing resource set.:
Iam tried the below code by using session to get existing resource set.iam getting the resource set but if I try to add resources to thet throws an exception

Session local_createdSession = SessionManager.INSTANCE.
getSession(sessionResourceURI, local_monitor);

Iterator<Resource>local_it =local_createdSession.getSemanticResources().iterator();
//URI gt =URI.createPlatformResourceURI(local_descriptionFile.getFullPath().toOSString(),true);
while (local_res==null && local_it.hasNext()) {
Resource local_r = local_it.next();
if(local_semanticModelURI.equals(local_r.getURI()))
{
local_res=local_r;
}

}
global_domain.getCommandStack().execute(new RecordingCommand(global_domain) {

@Override
protected void doExecute() {
/* adding the contents of arEobject to resource */
local_res.getContents().add(global_autosarobj);
try {

//local_createdSession.save(local_monitor);
local_res.save(Collections.EMPTY_MAP);

} /*End of try*/
catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}/*End of catch*/

}/* End of doExecute() */
});

it is throwing the exception if I go through session

Hi,

If your question is about adding new resources in the Sirius Session, you can take a look on org.eclipse.sirius.tools.api.command.semantic.AddSemanticResourceCommand.
But more generally, add a new Resource to a ResourceSet is not specific to Sirius. Don't hesitate to ask EMF related questions on the EMF forum.
