OK thismay look long do to code but put simply -- I created a Jframe to act as a navigation box. Upon slecting a product I want to open a new Jframe that is pretty much another class in the same package

Package: package my.SDP; (confusing name convetnions I know)
Selection class: SDQ.java
Selected Product: SDP.java

I want to select the product in simple SDQ pulldown (as I have) and then open SDP jframe (also works). Where the ??????????? marks are below is my problem! In SDP I renamed the main to aa but my call says it doesnt know aa or Im a putz! and its public. DO to the length of this code I am giving max points.

SDQ: simple pull down to choose product:

Ok, here is *a* solution:

Change the if in the SDQ to:

        if (selectProduct == "Archive Appliance")
        {
            SDP.aa();
            this.setVisible(false);
            this.dispose();
        }

and in SDP.java change the signature of the aa(..) to:

public static void aa()

It will close the current frame and open up the other frame.

Good luck,
Mark
