Are you referring to Swing or Eclipse SWT? either case, post some sample test case so it will be more clear.

SWT!

getSite().getPage().addSelectionListener(new ISelectionListener() {
public void selectionChanged(final IWorkbenchPart workbenchPart,
final ISelection selection) {
IStructuredSelection structuredSelection = (IStructuredSelection) selection;
final TreeEntity treeEntity = (TreeEntity) structuredSelection
.getFirstElement();
setPartName(treeEntity.getName());
text.setText(treeEntity.getName());
try {
getSite().getPage().showView(CorporationView.ID,treeEntity.getName(),IWorkbenchPage.VIEW_CREATE);

//this,I will refresh another viewpart .How to do?
