I like to try and keep my exception handling code separate from my other code so I usually create a helper method that does the actual logic and the outer method just deals with exception handling. I've always thought this gives the code a clean look and makes it more readable.

{
    try
    {
        tryStuff();
    }
    catch (SomeLibraryException e)
    {
        logger.log("Some message happened", e);
        throw new MyException(e);
    }
}

public void tryStuff() throws SomeLibraryException
{
   // Do things in here that could throw exceptions
}
