Listing the repository content

Hi there

I have a problem for listing the modules of a repository.  In fact I
need to list the repository content (for the user to choose a module
to import).  I've read several times the content of this newsgroup and
I have tried different ways, but I can't get to have the famous list
:-(, so I need a little help !

I first tried to use a CheckoutCommand with a ModuleListBuilder(), but
the result was empty. I've read that this command just lists the
content of the CVSROOT/Modules files.  In my case, that file is empty.
 I notice that Eclipse can list my repository even if that file is
empty so I must also be able to do it (?)

Then I tried with the hack (described in the bug track
http://www.netbeans.org/issues/show_bug.cgi?id=35239 ) to list the
directories in the repository.  Using the same way on a command line,
i get the same informations :
cache:/tmp/justATest# mkdir CVS
cache:/tmp/justATest# vi CVS/Entries
cache:/tmp/justATest# vi CVS/Repository
cache:/tmp/justATest# vi CVS/Root
cache:/tmp/justATest# cvs -n up -d
cvs update: Updating .
cvs update: New directory `CVSROOT' -- ignored
cvs update: New directory `demo' -- ignored
cvs update: New directory `nouveau' -- ignored

In fact, the "-- ignored" directories is the information I need ! But
how can i get those informations ? I can just have a String out of a
MessageEvent (for exemple : "cvs update: New directory `nouveau' --
ignored") but not the directory .... is there a way to do that ?
what's wrong in my code ?

Thanks for helping ! (excuse my poor english ... )

Here is a sample of my code :


/*
 * returns the modules list from the specified CVSRoot.
 */
public static Vector<String> getModulesList( CVSRoot cvsRoot )
throws AuthenticationException, CommandException {

    boolean debug = true;

    // Here there is a hack to get the modules list (more Precisely, the
    // repository content) with the javaCVS lib. It is discused in the
    // project newsGroup.
    // We will implement an algorithm described in the JavaCVS bugtrack
    // as #35239 .
    //
    // see bug track: http://www.netbeans.org/issues/show_bug.cgi?id=35239
    // see Newsgroups: gmane.comp.java.netbeans.modules.javacvs.devel
    //
    // TODO a better way to get the modules list....

    Vector<String> modulesNames = new Vector<String>();
    try {

        // Create an empty temporary folder
        File aTempFile = File.createTempFile("cvs-tempDir", "");
        String aTempFileName = aTempFile.getAbsolutePath();
        aTempFile.delete();
        File aTempDir = new File( aTempFileName );
        aTempDir.mkdir();
        if (!debug) aTempDir.deleteOnExit();

        // makes a CVS sub-folder
        File cvsDir = new File( aTempDir, "CVS" );
        cvsDir.mkdir();

        // Create CVS/Entries file with "D\n" content.
        File cvsEntries = new File( cvsDir, "Entries" );

ok and validated
