AS/400 connectivity using java by jt400 api

Question

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

Hi,
You could try posting with the code tags (http://forum.java.sun.com/faq.jsp#format). Few people are prepared to read that much code without pretty formatting.
Check out this forum aswell, it is dedicated to JT400: http://www-912.ibm.com/j_dir/JTOpen.nsf/By+Date?OpenView
