Question

Below is the plugin code that i have tried to reuse from an old code that i got my hands on.
The plugin just wont run properly.
I have copied the plugin part of the code.

Please help me trouble shoot the issue.

1. on running in Eclipse Helios
   
   UPDATED new error image
   
   
   but i am using JDK 1.6
   UPDATED new error image
2. Once i was able to run the plugin in RAD in debug mode, but was not able to install it in rad as a plugin. Since the plugin jar that was created, was not detected in Eclipse or RAD on start up.

the idea trying to achieve here is to get the <project folder location> when user tries to call the plugin. and pass that as a parameter to a stand alone code.

Activator.java

public class Activator extends AbstractUIPlugin {

    // The plug-in ID
    public static final String PLUGIN_ID = "PluginName";

    // The shared instance
    private static Activator plugin;


    public Activator() {
        plugin = this;
    }


    public void start(BundleContext context) throws Exception {
        System.out.println("Loading the PluginName");
        super.start(context);
    }


    public void stop(BundleContext context) throws Exception {
        plugin = null;
        System.out.println("Exiting the PluginName");
        super.stop(context);
    }

    public static Activator getDefault() {
        return plugin;
    }


    public static ImageDescriptor getImageDescriptor(String path) {
        return imageDescriptorFromPlugin(PLUGIN_ID, path);
    }
}

FindUnwantedJarAction.java

import org.eclipse.core.resources.IProject;
import org.eclipse.jface.action.IAction;
import org.eclipse.jface.dialogs.MessageDialog;
import org.eclipse.jface.viewers.ISelection;
import org.eclipse.jface.viewers.IStructuredSelection;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.ui.IObjectActionDelegate;
import org.eclipse.ui.IWorkbenchPart;


public class FindUnwantedJarAction implements IObjectActionDelegate {
    private IStructuredSelection selection;

    public void setActivePart(IAction arg0, IWorkbenchPart arg1) {
        // TODO Auto-generated method stub

    }

    public void run(IAction arg0) {
        IProject project = (IProject) selection.getFirstElement();
        String projName = project.getName();
        String projectLocation = project.getLocation().toString();

        //call another class with this parameter
    }

    public void selectionChanged(IAction arg0, ISelection paramSelection) {
        this.selection = (IStructuredSelection) paramSelection;
    }

}

</plugin>

Answer 1

You should also give your MANIFEST.MF for the full diagnosis, but the most probable cause is that you are running your RAD using a different JDK than the one your development Eclipse instance is running with (and it is earlier than your bundle target environment which is set to JavaSE-1.6 in your MANIFEST.MF).

That might be the reason you could successfully run the RAD in the Debug mode but not as a standalone application. Please look at the log of your RAD instance and see the “java.version=” value. It should be 1.6… or later.
