Accessing Workspace Services 
As a first step in using the Enterprise Workspaces API, you need to obtain access to the module context and workspace services, which is illustrated in the following example:
Example
private IWorkspace getWorkspace(IPortalComponentRequest request)
{
// Gets module context
IModuleContext moduleContext = ModuleHelper.getModuleContext(request);
// Gets workspace factory for workspace operations
IWorkspaceFactory workspaceFactory = (IWorkspaceFactory)RuntimeFactory.getWorkspacesRuntime().getService(IWorkspaceFactory.class);
IIdentifier workspaceIdentifier = moduleContext.getModuleID().getWorkspaceID();
return workspaceFactory.getWorkspace(moduleContext.getUser(), workspaceIdentifier);
}
Package
The relevant APIs are contained in the com.sap.workspaces.workspace, com.sap.workspaces.module packages.
