Most ftp connections time out, so you would have to have an auto-reconnect feature
right? This sounds like a kewl idea.

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
javax.naming.NamingException: Could not create resource factory instance,

org.apache.naming.factory.ResourceFactory.getObjectInstance(ResourceFactory.
