finally with no try/catch?

[kaeli]

Hey all,

At the moment, I have a web application that has an error page that catches
all my errors. This works great. When any of my classes throws an error, the
app forwards on to error.jsp so users can see the error message.
The thing is, classes that throw errors when DB connections, files, and
whatnot are open would get messed up if I didn't close things. So what I did
was to use a try/catch/finally block so that I could close things in the
finally block and just re-threw the exception.

Is there a more elegant way to do this?
I mean, catching errors just to throw them again is rather silly.
But if it's the only way I get a finally, it'll have to do.

The classes in question are beans that are used in a JSP intranet app if it
matters or helps. No struts, I'm afraid, nor Tomcat.

Why do you catch the Exception in the first place? You _can_ use

try {
// ...
} finally {
// ...
}

just as well. No need to catch anything. In fact, AFAIK this is the main
use for finally.

I thought I HAD to catch it if I was using try.

This was exactly what I was asking if I could do.
Thanks!

Hi kaeli,

as mentioned by Stefan Schulz
the try-finally block should work.


try{
}finally{
}
