unable to fetch data from app engine datastore(using JDO Queries)

Question

I am trying to fetch data from app engine with no success. The Async call is a success but there are no data printed. There are no errors either. It worked fine when I was using backend database. Now I am trying to get the same project to work with app engine datastore. I am using JDO queries. Below is the 'get' method:

public Projects getProjects(String projectname) throws NotFoundException,
        NotLoggedInException {
    checkLoggedIn();
    PersistenceManager pm = getPersistenceManager();
    Projects proj = null;
    try{
        Query q = pm.newQuery(Projects.class);
            q.setFilter("projectname == projname" );
            q.declareParameters("String projname");
        List<Projects> result = (List<Projects>) q.execute(projectname);
        for(Projects et : result){
            proj = new Projects(et.getPID(), et.getProjectName());
        }
    } finally {
        pm.close();
    }
    return proj;
}

I am not sure where it is going wrong. Any suggestion would be greatly appreciated.

Thanks

The source code looks fine, so there may be something wrong with the data or the JDO configuration. — Martin Berends, Feb 25 '14 at 22:16
Martin Thanks. Somehow it is working now, It is getting the project name and ID, though I did not make any changes! — suprasad, Feb 27 '14 at 05:17
I would log the cause of the error as "Pointy haired boss was signed in for a long time when it happened". True, no? — Martin Berends, Feb 27 '14 at 06:47
