Display exception information in struts in the JSP page __js

It is quite handy to handle exceptions in struts, whether it's struts1 or struts2, and configuring global exceptions is OK ~

To print out the exception information in the page:

The processing method in Struts1:

<c:out value= "${requestscope[' Org.apache.struts.action.EXCEPTION '].message}"/>

Direct use of tags in struts2:

<s:property value= "Exception"/>: Output The exception information itself, throw to write their own information.

<s:property value= "Exceptionstack"/>: output exception stack information, a lot of detailed information.
