How to show content from jsp in Window?

[maxkliver]

I have a jsp with ExtJs application. I click a button and new window appers . In this window i want to show forms from another jsp. Its mean that i want:
1 Send parametrs to jsp.
2 Fill a forms according to these parameters.
3 Show froms in window.

Another way its send a parameters in second jsp and create window and forms in this jsp and show it.

Which way is more correct and how to realize it?

You are opening an Ext.Window why not put an Ext.form.FormPanel in it and load the form returning JSON to file the value of the fields.
