Re: Jasper 2 Question
Hm The original question was about line numbers on JSPs, when they are compiled, and when they are executed and throw exceptions, right? Yes, it was... I said use some tea because Tea, developed by Disney, goes exactly in that direction, not having middle layer .java files over which the line number get messed up, they simply compile a template straight into .class having both the advantage of compiled templates, and the advatage that line numbers, both at compilation and runtime, are preserved... I am simply pointing out an alternative solution to your problem of line numbers, if that's ridiculous, well, that's _your_ problem...

I would also like to see the comments in jasper1 ported over to jasper2.

No, the original question was about the debugging capabilities that have been removed from jasper2. Jasper used to mark the begin and end points in the original source in the java translation as comments in the form: // HTML // begin [file=/index.jsp;from=(0,0);to=(4,0)] Restoring that ability would be somewhat difficult as the parser doesn't track the endpoints of the nodes, just the starts. Jasper2 is able to output data that might be compatible with JSR-45.

RE: Jasper 2 Question
Lenny, disclaimer: I don't use JSP's myself so I might be totally off here... but there is the following comment in Tomcat 4.1 Release Notes: -- Using Jasper 1 with Tomcat 4.1: -- It is possible to use Jasper 1 (included in Tomcat 4.0.x) with Tomcat 4.1, as it has the same API and supports the same JSP API. To use Jasper 1 instead of Jasper 2, copy the two following JARs to $CATALINA_HOME/common/lib (overwriting the two existing JARs): * $TOMCAT40_HOME/lib/jasper-runtime.jar * $TOMCAT40_HOME/lib/jasper-compiler.jar However, users are urged to use the version of Jasper included with Tomcat 4.1 (Jasper 2), as it has much higher performance and scalability than Jasper 1. would switching back to Jasper 1 help?
