Struts 1 - NullPointerException for saveError

[Felipe Brancaleone]

Hi,

i'm using a Method to save my errors and return they in screen, in saveError(the method) i pass the parameters, mapping, request and a reference to the message that i want show(this reference is to a .properties file). When the line "return mapping.getInputForward();" is called, i receive a "Servlet.service() for servlet action threw exception java.lang.NullPointerException".

Thank's

>> PROBLEM SOLVED <<
In my struts-config.xml, the tag input was not there, i just put this tag and play.
