Java to submit forms on a web page

I have never used Java before, but may do so for a project I am working on at the moment. Can anybody tell me if you can use Java to submit a form to another target page (i.e. Java applet [a menu system] is in another frame).

Also, would there be any compatibility issues with various browsers that I should be aware of?

Hope you can help.

Cheers.

I'm not sure if I understand your questions, but this should help you out.

You can use the JSObject to communicate from Java to Javascript.  You can then write a javascript function to do the submit.  for example:

JAVA
-------

// Netscape imports
import netscape.javascript.*;
import netscape.plugin.*;

class MyClass extends Applet {
 
 ...

    public void submitForm()
   {
        try
          {
            m_window = JSObject.getWindow(this);
          }
      catch(Exception e)
          {
            e.printStackTrace();
                    }

      try
          {
            // submit form
            m_window.call("submitMyForm",null);
          }
        catch(Exception e)
          {
            e.printStackTrace();
          }

   }
}



Javascript
-------------

funtion submitMyForm()
{
      document.formname.submit();
}

You can find documentation on JSObject at http://developer.netscape.com.  This solution works for all 4.0 browsers and above.  Good Luck.

Using "javac form.java" at the command prompt I get the following errors:

form.java:2: Package netscape.javascript not found in import"

form.java:3: Package netscape.javascript not found in import"

form.java:5: "Superclass Applet of class MyClass not found. class MyClass extends Applet {"

form.java:7: Type expected.

Also - will this work in IE browsers?

Do I need to include the following:

import java.applet.Applet;
import java.applet.AppletContext;
import java.awt.*;
import java.awt.event.*;

aswell?

Cheers,

Ben.
