Check out the some of the Wddx samples at http://www.wddx.org. WDDX works great for passing complex data between JavaScript forms and servlets. WDDX is an XML markup that allows you to serialize complex data from one language (JavaScript for example) and then deserialize the XML into an Object in another language. Here's how you would write your app using WDDX: 1. Insert JavaScript form data into JavaScript WddxRecordSet object 2. Serialize record set into a WDDX packet using the JavaScript function WddxSerializer.serialize(recordSet) 3. Submit the WDDX packet in a post to a servlet 4. Deserialize the posted wddxPacket into a Java Wddx RecordSet object using RecordSet rs = (RecordSet)WddxDeserializer.deserialize(wddxPacket); 5. Use the servlet to process submitted data from the RecordSet object. -Spike > -----Original Message----- > From: Chris Gow [mailto:[EMAIL PROTECTED]] > Sent: Thursday, October 28, 1999 2:59 PM > To: [EMAIL PROTECTED] > Subject: Re: Best way to pass data between HTTP servlets > > > -----Original Message----- > From: Robert Martin [mailto:[EMAIL PROTECTED]] > Sent: Thursday, October 28, 1999 1:05 PM > To: [EMAIL PROTECTED] > Subject: Best way to pass data between HTTP servlets > Importance: Low > > > I am working on a servlet that generates an HTML table where > each table row > contains information about a row in the database along with a > checkbox.
