Hallo,

schau mal hier:

package de.tutorials.jdt.extension.popup.actions;

import org.eclipse.jdt.core.ICompilationUnit;
import org.eclipse.jdt.core.IMethod;
import org.eclipse.jdt.core.IType;
import org.eclipse.jdt.core.JavaModelException;
import org.eclipse.jface.action.IAction;
import org.eclipse.jface.dialogs.MessageDialog;
import org.eclipse.jface.viewers.ISelection;
import org.eclipse.jface.viewers.StructuredSelection;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.ui.IActionDelegate;
import org.eclipse.ui.IObjectActionDelegate;
import org.eclipse.ui.IWorkbenchPart;

public class NewAction implements IObjectActionDelegate {

  StructuredSelection structuredSelection;


  /**
   * Constructor for Action1.
   */
  public NewAction() {
    super();
  }


  /**
   * @see IObjectActionDelegate#setActivePart(IAction, IWorkbenchPart)
   */
  public void setActivePart(IAction action, IWorkbenchPart targetPart) {
  }


  /**
   * @see IActionDelegate#run(IAction)
   */
  public void run(IAction action) {
    if (null != structuredSelection) {
      Object element = structuredSelection.getFirstElement();
      if (null != element && element instanceof ICompilationUnit) {
        ICompilationUnit compilationUnit = (ICompilationUnit) element;
        try {
          IType[] types = compilationUnit.getTypes();
          IMethod[] methods = types[0].getMethods();
          StringBuilder stringBuilder = new StringBuilder("Type: ");
          stringBuilder.append(types[0].getFullyQualifiedName());
          stringBuilder.append("has Methods: ");
          for (IMethod method : methods) {
            stringBuilder.append("\n" + method.getElementName());
          }

          Shell shell = new Shell();
          MessageDialog.openInformation(shell, "Extension Plug-in", stringBuilder.toString());

        } catch (JavaModelException e) {
          e.printStackTrace();
        }

      }
    }
  }


  /**
   * @see IActionDelegate#selectionChanged(IAction, ISelection)
   */
  public void selectionChanged(IAction action, ISelection selection) {
    if (selection instanceof StructuredSelection) {
      structuredSelection = (StructuredSelection) selection;
    }
  }

}
