Program hang when opening vimplugin editor

[kristi]

I can't open the vimplugin editor.  Eclipse freezes when I try to open a file using the vimplugin editor. 

The installation seemed to go fine.  I used the eclipse update helper thing with http://vimplugin.sf.net/update.  I restarted eclipse and I see the vimplugin settings in the preferences.  The plugin seems to be registered in the PDE plugin registry.  I get two errors, "Category org.eeedit.view.category not found for view org.vimplugin.views.CommandView.  This view added to 'Other' category.", though these don't seem to be fatal, as I can open the VIM Command View from the "Snow View=>Other" menu.

I am using Fedora core 8 and the Fedora eclipse-platform package (installed via yum, ver 3.3.0). 

Errors when running eclipse from command line:

Trying to start vim
Server started and listening
Started vim

[kristi]

So, I've fixed this.  The WidHandler needs to return the parent.embeddedHandler in the getWid() function.  I also made the wid a long so it works with 64 bit systems, and added a sleep while the VimConnection is waiting to connect to the vim server.  Without the sleep, eclipse gets stuck waiting for the connection and hangs.  I will submit a patch to the devel list.

Code:
src/org.vimplugin.utils/WidHandler.java snippet
    public static long getWID(Composite parent) {
        Class<?> c = parent.getClass();
        Field f = null;
       
        try {
            if( Platform.getOS().equals(Platform.OS_LINUX) ) {           
                //f = c.getField(linuxWID);
                // the class reflection doesn't work on linux
                // return the embeddedHandle
                return parent.embeddedHandle;
            }
...

src/org.vimplugin/VimServer.java snippet
    public void start(String... args) {
        if (vc != null && vc.isServerRunning())
            return;

        //setup VimConnection and start server thread
        vc = new VimConnection(ID);
        t = new Thread(vc);
        t.setDaemon(true);
        t.start();

        // starting gvim with Netbeans interface
        try {
            System.out.println("Trying to start vim");
            p = new ProcessBuilder(args).start();
            System.out.println("Started vim");
        } catch (IOException e) {
            e.printStackTrace();
        }

        // Waits until server starts.. vim should return startupDone
        while (!vc.isServerRunning()) {
            // sleep so that we don't have a messy cpu-hogging infinite loop here
            Long stoptime = 2000L; //2 Seconds
            System.out.println("Waiting to connect to vim server…");
            try {
            Thread.sleep(stoptime);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }
