info.studio52.dao.ContentsDAO.getContentsById(ContentsDAO.java:73)
info.studio52.controller.HomeAction.home(HomeAction.java:42)

Is info.studio52 your package, Also paste your code (especially the code at the lines mentioned above).

Also you obviously(as the exception shows) are having some problem tracking your Array indexes,
We need your code to go on to diagnose the issue here apart from just the stack trace.

Also preferably when you post your code highlight the lines mentioned above. Cause chances are the lines nos in your code after pasting here may not be the same.

Please also remember to paste you code inside [code=java] and [/code] tags.

EDIT:
The stacktrace, however is better put in [code]

[/code].

Try asking this as a new question, with specific details of what your problem actually is (the more information the better) and in the appropriate forum as I'm guessing it's got nothing to do with either web development or JSP, and you might find that we can help you.

Hijacking a five year old thread in an unrelated forum, with a very vague and detail-light series of shouting (uppercase is never a good idea) posts/rants is not likely to get you much in the way of targeted help, let alone quick help. Just saying...

WHAT SHOULD I DO NOW THAT I NEED TO OPEN THE SOFRWARE THAT I'VE DOWNLOADA BUT IT CANNOT BE DONE SO.

HappyGeek told you what to do:
start a NEW THREAD in the CORRECT FORUM.
provide detailed information, and turn off the CAPS-LOCK.
