java.lang.Thread.run(Thread.java:536) >From this exception, can anybody tell me what kind of error im getting? it just says in which page the error is.. but can i know about the line number from which the excpetion comes.. and also.. the type of error... I am really unable to make out what the problem is.. please help.. Thanks in advance.. vidya > it just says in which page the error is.. but can i know about the line > number from which the excpetion comes.. There are some basic bugging techniques that might help here. The one that springs to mind is as follows. Keep trimming Java code out of the page (as 10 statements at a time) until the problem stops. Then put the last ten lines you removed back in, and take out 5 of those to narrow it down further. While your posting 197 lines of stacktrace was very ..complete, I doubt it will be of much use unless people here can see - The original .JSP - The URL at which it is failing, so they can see it in a browser As an aside vidya, you are posting from groups-beta and your posts are not 'threading properly' in my news client. Are you doing *anything* at all to the subject lines of replies to your original posts that might be causing that? Are you 'replying' to your first post or simply making a separate post with the same 'subject'?  SignatureAndrew Thompson physci.org 1point1c.org javasaver.com lensescapes.com athompson.info Beats A Hard Kick In The Face here, the subject is different, know? its about exceptions.. and my earlier qns was about javascript and all.... this one is completely different.. thatz y i post this as a seperate one. its true that im working on the same project when i post these topics. but i can have different kinda doubts even if i work on same project. rt? :) and about ur replies, im thanking u once again for ur valuable guidance. im reading the replies carefully and doing as its given.. > its true that im working on the same project when i post these topics. > but i can have different kinda doubts even if i work on same project. > rt? Please drop the cutesy 'im', 'kinda' 'tr' references in general, also use Capital Letters where appropriate. From sentences you wrote, such as this.. "While running my JSP page, I am getting an exception." ..it is obvious that your choice to use abbreviations and lower case is exactly that, a choice (rather than lack of knowledge, or experience). Such use loose of language can be difficult to understand and is generally frowned upon (around these comp.lang.java.* groups). [ I was about to add 40-50 more lines of explanation, about what I asked, and other aspects of debugging/posting, but.. ] In fact, now that I look into your posts more carefully, my advice is to read the entire PhyScy Java FAQ - from start to finish, since it mentions so many debugging and posting techniques that might be of use to you.
