How to pre-populate an actionForm in the perform method?

[Hartmut Bernecker]

Hello,

when a URL (myUrl.do) is invoced, the ActionServlet instantiates a
myForm (according to the struts-config.xml), forwards control to a
myAction object; the perform() method of myAction calls the reset()
method of the myForm object and then forwards to a JSP page.

Would some of you give me a piece of code that shows me how myForm can
be prepopulated with some data before been displayed by the JSP page??
IMHO that code should be in the perfom() method.

TIA for ur help!
