I tried storing templates in the database and it worked out well. I abandoned it for business reasons.
Basically in the init of each servlet I pulled the templates and compiled them. The only down side was that I did not have any means to update the compiled template. I was playing with a trigger sending a message to the application and setting a application variable. When the servlet is called it checks this variable to see if the template has changed. I never got the listener part working, but it should work. -Aaron ----- Original Message ----- From: "Mike Orr" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, April 25, 2002 7:46 PM Subject: Re: Re: [Webware-discuss] MVC and Servlets > On Fri, Apr 26, 2002 at 12:59:17AM +0200, Ernesto Revilla wrote: > > > That's > > > t = Template(templateDef, searchList=[orderData]) > > > to you, buddy. :) > > > > > > It's prob'ly possible with some work to store the precompiled > > > template module in the database and then exec it into a private > > > dictionary when you need it, but it's prob'ly easier to just > > > store the template definition in the databse and let it be > > > recompiled each time. > > How much does this cost?
