JNDI / pooling

[Viorel Dragomir]

Hi,

I can't describe exactly the problem because I'm not familiar with all the terms... 
But the big picture is that I want to create a pool of ftp connections to work like a 
database connection and I want to get the connection from JNDI.


So far I extended BaseKeyedPoolableObjectFactory and StackKeyedObjectPool and it works 
fine like this:

        FTPConnectionPool pool = new FTPConnectionPool();
        String key = "key";
        try{
        FTPClient ftp = pool.borrowClient(key);
        if( ftp.sendNoOp() ){
            System.out.println("OK");
        }else{
            System.out.println("NOPE");
        }
        
        pool.returnClient( key, ftp );
        }catch(Exception ex){
            ex.printStackTrace();
        }

But I want to make it work from "JNDI" almost like a datasource
            InitialContext ctx = new InitialContext();
            DataSource ds = (DataSource) ctx.lookup("java:comp/env/jdbc/backup");

Anyway I am completely lost if it can be done or not.
So far I get an exception when I try to start Tomcat:

GlobalResourcesLifecycleListener: Exception processing Global JNDI Resources
