I have an applet in the browser (IE only) that when an item is selected from a JComboBox, I would like to call the javascript function of window.showModalDialog(url, window); to create a modal browser on top of the current browser. I don't want the user to return to the initial browser until they have finished with the modal browser. How do I have the applet signal javascript to call the modal dialog function when the item is selected from the JComboBox?
Also, I need to pass some data to this new page, such as file id, service name, etc. Is there anyway I can do this besides putting this data in the query string?
Thanks in advance for your help!!

Hi,
Yes you can, you have to use netscape.javascript.JSObject class to do that. Please see other postings which are similar to your query.

Will this JSObject work in IE? My application needs to work in IE only. Are there any issues with this?
Also, please address this question:
"I need to pass some data to this new page, such as file id, service name, etc. Is there anyway I can do this besides putting this data in the query string of the URL?"
Thanks for your response.

Verduka,
Yes it works in IE as well. But the catch is that this class has to present on the client side. Thats not a big deal as you can bundle JSObject class along with your applet and send it over.
As far as your other question goes, u could have hidden fields, or if there is a session associated with this application, then the values can be passed via the session object.
Hope this helps !!

Where do I get the class file from? How do I use JSObject to have the applet communicate with javascript?

As far as your other question goes, u could have hidden fields, or if there is a session associated with this application, then the values can be passed via the session object.


How would I use hidden fields? The values are set in the applet. How would I set the value in the applet to a hidden HTML element?
How do I get the applet to set values in the session object? Can you give me some sample code please?
Thanks so much for your help!

verduka,
JSObject class comes with the netscape browser, it will be in a file called java40.jar. Extract only JSObject.class from the jar file, i think that will be the only class file which would be useful.
To see the api for JSObject follow this link
I think i got your other question wrong, i thought u wanted to pass the values from one jsp/servlet to another.
Well you can call javascript functions from an applet using JSObject, well thats abt it.

The location the the file "java40.jar" would be
c:\Program Files\Netscape\Communicator\Program\java\classes\java40.jar.

Ok, I am now using the JSObject to call methods in javascript from my applet. Now my problem is that when I try to open a modal dialog using the server cannot load the page. The jsp is instantiating a bean to dynamically determine the text it should display. I tried using a static html page as the target of showModalDialog, and that worked with no problems. Is there a problem opening a jsp on the modal dialog? Or is there a problem instantiating a bean?
Here is the error text from the server when I load the jsp:
SERVER ERROR
This server has encountered an internal error which prevents it from fulfilling your request. The most likely cause is a misconfiguration. Please ask the administrator to look for messages in the server's error log.
Your help is greatly appreciated!!
