jsp - Catch custom exception in web.xml -


how create custom exception , handle in web.xml error-page tag direct specific page.

i have tried create exception extends servlet exception this.

public class myexception extends servletexception {      private static final long serialversionuid = 1l;      private string[] errarray;      public myexception (string[] errarray){     this.errarray = errarray;     }      public string[] geterrors(){         return errarray;     } }

then put inside web.xml

<error-page>     <exception-type>my pach exception.myexception </exception-type>     <location>/web_service_errorr.jsp</location> </error-page>

and tried throw in project. exception still catch 

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

at beginning of error message javax.servlet.servletexception, has root cause myexception in message.

if not doing right, how should catch custom exception , redirect jsp page?
