[Webwork-devel] Re: Re[2]: Jasper Reports

[Maurice P. <Ma...@Vi...>]

Peter,

Let's move this back to webwork-dev since we're beginning to discuss the 
implementation. I've left the full history tacked on so others can catch 
up.

We should all have such jobs.  :-)

It's interesting.  I'll think more about it tomorrow.

Take a look at what I just put into CVS and see what you think.  It's 
rough still, but at least you can see where my thought process is heading.

One thing that will be a high priority soon will be caching the compiled 
JasperReports for performance reasons.  (or we force people to precompile 
before deploying which isn't convenient).

It's late here and I'm going out for a night cap.  Have fun at work.  If I 
code while you sleep and you code while I sleep this will get done in no 
time.

P.S.  Mike, I'll take the beer instead of that man-love you offered me.  :
