That is not a good practice that executing the code in catch block.

How ever if you want to show an error page for user,you can specify that in web.xml

 <error-page>
    <exception-type>java.lang.Exception</exception-type>
    <location>/error.jsp</location>
  </error-page>

If you want to show error pages by error codes (e.g 404,500 etc..or for custom exception handling) please refer this .

And a mini tutorial on this by @BalusC

EDIT:

You need not to do anything with code now.You can simply write

try
{
 //some code..
}
catch(Exception e)
{
System.out.println("error==>"+e);//better to write e.printStacktrace() here.
}

When error occurs the error page automatically shows in browser.
