Without showing us what's on line 7 of main.jsp there's not much to be said.

I'd suspect a problem in the TLD definition of the tag.

And, please enclose any posted code in UBB code tags to preserve the formatting, and use the 'disable smilies' checkbox when posting. In fact, I'd strongly encourage you to go back and edit your post to fix these formatting issues if you want people to be able to read your posted code.

Clicking the icon that looks like paper and pencil will allow you to edit your post.

Could you check your server logs to see if you get a more specific error?

All classes used in a web app should be in a package other than the default. Place your tag handler class in a non-default package.
