How to add a throw exception to a servlet
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
The doPost method of a servlet looks like this :
public class selectdetail extends HttpServlet {
public void doPost(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
What if in my doPost method I am using Object methods that throw other
exceptions, like SQLException. The Java compiler would not let me write :
public void doPost(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException,SQLException
But I want the exception to be caught in the error.jsp page, not do a try
{...} catch{...} inside the doPost body.
I don't know if I explained it correctly but is there a simple solution to
this problem ?

Hi,
There's no way to add new exception types to the doPost method. However,
you could do something like:
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
{
try
{
/*
your code
*/
}
catch (SQLException exc)
{
throw new ServletException(exc);
}
}
This way, the real exception goes nested within a ServletException and you
don't have to change the method signature.
Hope it helps,
Ion

Hi Raphel,
Can you let me know why you have this peculiar requirement of
changing the signature of the doPost method ?
Rgds,
Chetan
