GZIP is described here: http://www.gzip.org/ Since you are using Tomcat you dont need to do anything in your code to turn on GZIP compression. Tomcat's Coyote connectors support GZIP natively and are *extreemly* configurable when it comes to turning it on and off as well as when/if compression occurs. Please check out the Tomcat admin guide at http://tomcat.apache.org/tomcat-5.5-doc/config/http.html See the "compression" attribute of the <Connector> tag in server.xml. NetBeans. Well, that has nothing to do with this. An IDE is an IDE. As for using say the <mx:WebService> tag, please simply refer to the Flex documentation. -- Dave Wolf Cynergy Systems, Inc.
