["Suriyanarayanan, Senthil Kumar" <se...@capitalone.com>]

Hello,

struts-config_1_0.dtd says, action tag takes
parameter attribute as..

     parameter       General purpose configuration parameter that can be
used
                     to pass extra information to the Action selected by
this
                     mapping.

	I would like to how to mention in struts-config.xml and refer it in
the perform method of the action.

	Any help would be appreciated.

Thanks
Senthil Kumar.S

The mapping is passed to perform(), so you can access the parameter like
this:

String parameter = mapping.getParameter();

To pass multiple parameters, you could set it up like a query string
(p1=this&p2=that), and then use 

Hashtable parameters =
HttpUtils.parseQueryString(mapping.getParameter());

to get them out.
