Jasper option for "whitespace-optimized" HTML output

           Summary: Jasper option for "whitespace-optimized" HTML output
           Product: Tomcat 4
           Version: 4.1.27
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Enhancement
          Priority: Other
         Component: Jasper 2
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: bernd.steinert@gmx.net


Jasper generates servlet code, which doesn´t trim any whitespaces from the
original JSP sourcefile. This causes the HTML output to have lots of empty lines
and tabs and blanks. In Tomcat 4.1.27 I simply changed 
org.apache.jasper.compiler.Parser.parseTemplateText(Node parent)
to trim whitespaces (see Attachment).

good effects
------------
In a sample application this reduced the generated HTML code by approx. 30%
without any negative side-effects. 
The jasper-generated Java source has no more 'out.write("\n\r");' so we save
some complete method calls.

bad effects
-----------
Generated HTML is unreadable (which may be OK for productive installations)
(any others???)


I think of this enhancement as an optimization parameter, most useful for
productive installations. So this should be made configurable via CLI and in
$CATALINA_BASE/conf/web.xml.

What do you think about this???
