What can also be done is to package your applet within a JAR, and sign it. In most cases (including the JRE default install), signed applets are granted "all permissions", as long as you grant the certificate. The JDK tools provide a way to generate the necessary keystores and certificates (including self-signed):
keytool docs: http://java.sun.com/j2se/1.4.1/docs/tooldocs/windows/keytool.html jarsigner docs: http://java.sun.com/j2se/1.4.1/docs/tooldocs/windows/jarsigner.html One additional note: these questions are Java-specific, and there's a much more useful places to get help with these, such as http://developer.java.sun.com/ or the new http://java.net/. I would suggest you try any further questions there first, unless your questions deal specifically and directly with Jabber. You'll get much more prompt responses there than here (-: - LW On Fri, 2003-07-11 at 06:03, Dov B Katz wrote: > The jabber server needs to run on the same hostname that the webserver is running > on.
