Can someone explain when tags are executed? Namely, custom tags and the <sql> tag.
The problem is we currently have a web app that has a jsp's JavaScript communicating with an applet that can query a database. It allows us to do real-time validation against database values. We know it is bad design. It's an older system and already have vowed not to use it in future projects. However, testing with XP service pack 2 is freezing the applet. So we are trying to come up with some alternatives without having to redesign and rewrite portions of existing apps. Someone came up with the idea of using the <sql> tag, but I thought that ran on the server before the response was sent to the browser, thus it wouldn't work for real-time validation. Would a custom tag work? Or are those run on the server as well?
Thanks, Karl

As I understand it, a tag generates code which shows up in the generated .java file and that generated code can call/use code which is in a .jar file referenced by the tag library. It all executes on the server
The generated HTML that gets sent to the browser is the only thing that executes in the browser.
