what is the difference between
Hi guys i am having problem with the Web Application:
I wrote a program in Jsp+JavaBean, Microsoft Access Database, this program runs smoothly in Windows 98/Me+Apache+JRun developer version, but when I put it on the ISP's Server, it always (not every time) cause "Jrun Closed Connection" , i can run the program only when i restart the JRUn Server again. the ISP's environment is: NT server 5.0 + IIS + Jrun 3.02.
here are the code:
when the first jsp page(user.jsp) display, click on the "Add" link should make the second jsp page(adduser.jsp) display. but generally after you click on the link , "Jrun Closed Connection" message come out.
