Hi Helen:

Due to Java security, applets may only open connections to URLs that are
on the server from which the applet was loaded.  In this case,
therefore, you would have to either load the applet's class files or the
HTML that starts the applet from the server.

If you create a signed applet, you can also overcome this.

And yet another possibility is to have the applet talk to a VisAD
application on your server, and have the application do the actual
loading of the image...or whatever data you're going after.

Hi,

I am trying to use Java Applet from the web browser to query the remote
image objects from the remote ADDE  server.
But  I got the following error message:

Error openning connection: java.net.MalformedURLException: unknown
protocol: adde

I have added a static block to load protocol for ADDE URL at the
beginning of my Applet code.

Thanks for your help.

Helen
