I'm not sure what is wrong with my applet. Originally I had an applet that accessed a file and outputted it to a servlet. I then wanted to add a progress bar but the file access and transfer process were to intensive to make the progress workable. I moved the progress bar to a thread and the file access and transfer also. Now the progress bar works but there seems to be a problem with connecting to the servlet. A case of fix one thing brake another. Has anyone any ideas as to why this may be the case. The code is the same as I just pass datainputstream and a dataoutputstream to the thread and reuse the same codefrom there. The file inputs correctly and I have tried the older version of the code and it still works. Thanks for any help and ideas you can give.

Hi while progg with threads,
plz take care of the following things
1)Starting point of each thread
2) Is these threds use a shared resource. If yes, then check any possiblilty of concurrent access.
3)Whether All threads stopped properly.

It's not one of the ususal thread problems, it is something a little more subtile than that. I believe the problem to be with my DataOutputStream not being initialised in the thread despite being passed references to the streams. Anyone think that sounds familiar?
 
Don't get me started about those stupid light bulbs.
