You may need to do:

catch(Exception e)
{
    out.println( "<pre>" ) ;
    e.printStackTrace( out ) ;    
    out.println( "</pre>" ) ;
}

>> e.printStackTrace( out ) ;
this won't always work. because out is JspWriter by spec. use this:

e.printStackTrace( new java.io.PrintWriter( out ) );

To trap errors, you can specify errorpage entries in the web.xml file. Specify the error page you want to forward the error to . Javabean should throw an exception . Automatically the error page will be called.
You have an implicit object exception in the error page alone. Use that to print exceptions.

If you need more details let me know.
