plain java snippet work item

in plain java ,snippet5. java creates a work item.But

I don't want to create a new project area in jazz platform , it is not important the code is java or egl. the code is first create a project area ,then create work item. i wanna create work item in existing project areas in Jazz platform.

The code like this ;

public static IWorkItemHandle createWorkItem(ITeamRepository repo, IProgressMonitor monitor) throws TeamRepositoryException {
ITeamAreaHandle teamAreaHandle = Snippet3.createProject(repo, "Snippet 5");
ITeamArea teamArea = (ITeamArea) repo.itemManager().fetchCompleteItem(teamAreaHandle, IItemManager.DEFAULT, monitor);
IProjectAreaHandle projectArea = teamArea.getProjectArea();
IWorkItemClient service = (IWorkItemClient) repo.getClientLibrary(IWorkItemClient.class);
IWorkItemType workItemType = service.findWorkItemType(projectArea, "defect", monitor);
IWorkItemHandle handle = service.getWorkItemWorkingCopyManager().connectNew(workItemType, monitor);
WorkItemWorkingCopy wc = service.getWorkItemWorkingCopyManager().getWorkingCopy(handle);
IWorkItem workItem = wc.getWorkItem();
try {
List<ICategory> findCategories= service.findCategories(projectArea, ICategory.FULL_PROFILE, monitor);
ICategory category = findCategories.get(0);
workItem.setCategory(category);
workItem.setCreator(repo.loggedInContributor());
workItem.setOwner(repo.loggedInContributor());
workItem.setHTMLSummary(XMLString.createFromPlainText("Example work item"));
IDetailedStatus s = wc.save(null);
if(! s.isOK()) {
throw new TeamRepositoryException("Error saving work item", s.getException());
}
} finally {
service.getWorkItemWorkingCopyManager().disconnect(workItem);
}
workItem = (IWorkItem) repo.itemManager().fetchCompleteItem(workItem, IItemManager.DEFAULT, monitor);
monitor.subTask("Created a work item " + workItem.getId());
return workItem;
}
