forward problem with frames

[Stefan Faist]

Hi all,
why have a frameset and open a link without this framset. Then I want to go
back to the frameset with this forward.
<forward name="start_mitarbeiter" path="/main.jsp"/> the main.jsp is the
page with the frameset.

But this forward opens a new window? Why does it do that and how can I open
this in the same Window? This forward called with a html:submit tag in the
action class. With a link I have the target parameter but with the button I
havn't nothing or ...?

Can somebody help me?

Stefan
