Hello,
Thanks for your reply. I have a little problem when i try to open the view of my plugin. I have the following view class. The intention is to create a view with a label and i set the text of the view to just the name of a SimpleName element. This is the class:
public class TableView extends ViewPart{
public TableView(){
}
public void createPartControl(Composite parent){
GridLayout gridLayout = new GridLayout();
parent.setLayout(gridLayout);
Label label = new Label(parent, SWT.CENTER);
ICompilationUnit icomp = this.findProject();
CompilationUnit comp = this.parse(icomp);
SimpleName sn = ((TypeDeclaration)comp.types().get(0)).getName();
label.setText(sn.getFullyQualifiedName());
}
public void setFocus(){
}
protected CompilationUnit parse(ICompilationUnit unit) {
ASTParser parser = ASTParser.newParser(AST. JLS3);
parser.setKind(ASTParser. K_COMPILATION_UNIT);
parser.setSource(unit); // set source
parser.setResolveBindings( true); // we need bindings later on
return (CompilationUnit)parser.createAST(null /* IProgressMonitor */); // parse
}
public ICompilationUnit findProject(){
IWorkspaceRoot root = ResourcesPlugin.getWorkspace().getRoot();
// "org.integrated.project.soul" is the project name
IProject project = root.getProject( "org.integrated.project.soul");
if (project.exists() && !project.isOpen())
try {
project.open( null /* IProgressMonitor */);
} catch (CoreException e1) {
e1.printStackTrace();
}
IJavaProject javaProject = JavaCore.create(project);
IType lwType = null;
try {
// "Menu" is a class in the "org.integrated.project.soul.gui" package
lwType = javaProject.findType( "org.integrated.project.soul.gui.Menu");
} catch (JavaModelException e) {
e.printStackTrace();
}
ICompilationUnit lwCompilationUnit = lwType.getCompilationUnit();
return lwCompilationUnit;
}
}
After i execute the project as "Eclipse Application", i get a new workspace and when i try to open the view, i get the following errors and exception:
Error creating the view

In the newsgroup I see two questions from you, both of which were answered
on the same day. That's a pretty good result, I'd say.
If these answers didn't provide the help you were seeking, maybe you should
try to state more precisely, what it is you are stuck with.
best,
Stephan
