Java Database Connectivity (JDBC)

I am making a project on Java Swing. I am having an AS/400 machine i am saving the spool files on AS/400 Machine as .txt and accessing it from a remote Windows Machine. I have made an UI to connect it to the AS/400 machine using JT400 API's. I am having 300 spool files(.txt) in the library on AS/400 machine. I m accessing this library to get the list of spool files basically .txt files. Now I am using JT400 OpenAsynchronously method but the program gets hanged over there and displays on 25 files. I don't know what to do please help
