You shouldn't have Java source in a JSP page.

Perhaps you are aware that 'exception' is a predefined variable in an error 
JSP that has value only when there actually is an exception? Or perhaps you 
mean something different by "compiled" than I do? You send us these code 
fragments that yield no context. On the face of it I don't know how your code 
fragment was able to compile successfully.

I trust that you are not, indeed, doing that from a JSP page. That would be 
ghastly.

Also, don't throw 'Exception', throw a suitable subtype.

Also, I trust that you are both including relevant information in the message 
of the exception, and logging it.

Who knows? We can't unless you tell us. But based on what you post, it sounds 
like your code needs an awful lot of work.
