RE: Using Jasper for template processing?
How about using stock Jasper, and then applying an XSL transformation to the HTML output to clean out the HTML specific code. Seems like extra work, but would you would not need to modify the Jasper code itself.

Re: Using Jasper for template processing?
Hi Jaroslav,
I already make use of user-defined JSP templates on my site
http://www.zzpost.com/. The
webapp runs a user-defined JSP then uploads the output to the users own
website.
The question you need to ask is, for what reason would you take the time and
trouble to "decouple" servlets from http? That is a lot of work for nothing
IMHO.
Just create your system so that it is web-based and you'll be fine.

Subject: Using Jasper for template processing?
Hello Tomcat developers and advanced users!
I have following question:
I would like to use Jasper engine for template processing. I use
Tomcat with JSPs and its good, but I would like to alter Jasper usage
this way:
An JSP page is compiled into a Java source where the user's JSP
page extends the class HttpJspBase and overrides several methods
notably _jspService().
I want to use Jasper for more generic task. Template processing
independent on Servlets and HTTP. Imagine following interface:
public interface Template {
void renderTemplate(Writer out) throws java.io.IOException;
}
I want to alter Jasper to process files with JSP-like syntax (of
course with other intrinsic variables accessible inside the
renderTemplate() method) and generate Java source code implementing
the Template interface and than compile the source code using Java
compiler into executable classes. Then load and run generated classes
as they have been written manually.
So I ask:
1) is is possible or is Jasper tightly coupled with HTTP and Servlet
API?
2) if it is possible, how to do that? (which classes can be re-used,
which interfaces and classes have to be re-implemented
3) how much time it can take (1 day, 3 days, a week, two weeks, ...)
Thanks for any comments and suggestions.

RE: Using Jasper for template processing?
Remember, Servlets are not necessarily HTTP beasts. The servlet spec (from
my perusal) specifically leaves open what kind of environment the servlet
will live in. This is why there are specific HTTP extentions of the base
servlet classes. Now, that being said, I don't know of any other way to use
the servlets except in a web environment. But, being able to do what JG
wants can be useful - for instance, to periodically dump a formatted report
to a static file, so that daily reports are available and can be processed
during system off peak hours.
