passing a Vector from JSP to an applet

[Scott Williams]

Is it possible to pass a Vector from JSP to an applet? If so how? Thanks in advance.

Hi, you can pass Vector thru the applet tag using scriplet to iterate through the Vector elements as applet parameters. Or you can send the Vector as a stream and open a URLConnection in applet. But this only works for elements that are String.
Maybe someone can help.

You can pass it as a serialized object from JSP to applet. Use ObjectOutputStream from the response object and send the vector. The applet should use the ObjectInputStream from the response object and retrieve the vector. Very simple.

JavaRanch Common package has classes to send objects between an Applet/ Application and a Servlet.

Thanks for your replies. I am encountering this exception (java.lang.IllegalStateException) now when the following line of code is being executed in my JSP.
ObjectOutputStream outputToApplet = new ObjectOutputStream(response.getOutputStream());
Any ideas???
Thank you.

I think the problem here is that the default output stream for JSP is of type JSPWriter and I am trying to change it to ObjectOutputStream. What do you guys think? Any experience with this??

I think you can only call getOutputStream once and the JSP engine has already done that to create the JSPWriter object out. You may find that you'll have to use a Servlet to do Object communication.
