>From the format of the error message, this is some version of Tomcat 3.3.x. To get more information, add the attribute debug="99" to the <JspInterceptor /> element in server.xml (and, of course, restart Tomcat :).
<[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] Hi Tomcatters, we run two Tomcats on two separate hosts which are assumed to be configured exactly the same (at least as far as Tomcat, Java env, and this webapp are concerned). I have no knwoledge of Tomcat webapps like JSPs and Jasper whatsoever (only administrating the server). While when the same query path of the URI is called from a client's browser against both hosts, and the same piece of JSP should get executed there, it works fine on one host whereas on the other Tomcat host we get a Jasper exception. Because of my lack of knowledge of Jasper I cannot find the source of the error where both Tomcat hosts could possibly deviate from one another. If it was a legacy CGI program or script I would know how to help myself. Here is the exception pass stack trace through the Jasper classes from the host where this particular request crashes, taken from its Tomcat log. Maybe any Java/Jasper knwoledgeable person can detect something from it? Maybe I could even raise the verbosity level (by somehow enabling debug mode) of Tomcat? Can this be done on a running Tomcat? How could I raise the logging level to Debug, maybe by passing the Java master thread some -D switch definition? But this would then require a Tomcat restart I suppose? Since I even lack the most basics of JSP (thought it was only some sort of templating/embedding of Java code in ordinary XHTML) I am not even familiar with when and how the Java source gets compiled and thus could produce the below Jasper exception (it simply suggests a wrong invocation of the Java compiler, as it looks) Wasn't it that servlets or JSP got only compiled the first time they were executed by the servlet engine, and thereafter remain resident in memory?
