[Java 7 SE+MySQL+NetBeans 7.2.1+jooq 2.4.2]NoClassDefFound error

[KernelPanic]

Dear Sirs and Madams!

I have included jooq 2.4.2 sql query builder into my project and in this project I have CDatabaseManager singleton class, which is responsible for all data operations. Now, I try to execute query with jooq with code:

    public static ArrayList<String> getMultimediaExtensions(final String category) throws SQLException
    {
        ArrayList<String> results=new ArrayList<>();
        Factory create=null;

        try
        {
            if(CDatabaseManager.openConnection(CDatabaseManager.host(),
                    CDatabaseManager.dbName(),
                    CDatabaseManager.username(),
                    CDatabaseManager.password(),
                    CDatabaseManager.port(),
                    CDatabaseManager.sslEnabled()))
            {
                create=new Factory(CDatabaseManager.dbConnection(),
                        SQLDialect.MYSQL);
                Result<Record> r=(Result<Record>)create.select().from("testMultimediaTable").fetch();
            }
        }
        catch(SQLException | DataAccessException ex)
        {
            System.out.println(ex.getMessage());
        }
        finally
        {
            if(!CDatabaseManager.closeConnection())
            {
                results=null;
            }
        }

        return results;
    }   // getMultimediaExtensions

Once I try to execute this method, I get:

Now, is it mandatory to create xml database map for jooq or not? I've included both mysql connectior jar and jooq jar's into my project, why do I get this error? And db connection is established succesfully, since I can see it in MySQL Workbench!

Sincerely,
Marko

You have the jooq.jar on your runtime classpath?
That's where I would be checking.

I've set jooq.jar in Netbeans in Compile time:

[Tolls]

Not sure.
Does Netbeans include all the jars contained in the folder, or is it treating the folder as if it was a directory containing classes?
I would include the jars individually and see if that works.

I got rid of the error, I had some "stealth" exception and then the class coud not be found. I've fixed it!
