RE: can tomcat give me page loadtime stats?
Good. Thanks. Now, a little help is requested in how to use AccessLogValue. (and now that I read the first answer, I realize that I might not have phrased my question as unambiguously as possible). I'd like to have the following information logged: page x took y milliseconds to create (or something like that) According to http://jakarta.apache.org/tomcat/tomcat-4.1-doc/catalina/docs/api/org/ap ache/catalina/valves/AccessLogValve.html, I would use %U for x (the page's URL), but what would I use for y (the amount of time it took to create the page)? %t only gives me the date and time it was requested, not how long it took Tomcat to calculate the page's contents.

RE: can tomcat give me page loadtime stats?
I have a feeling that these variables (%D and %T) are not available in 4.1.12 as they don't actually resolve to anything in the access log. I can determine that they were added in AccessLogValue (ver 1.3), but I don't know what the CVS tag is for version 4.1.12 (ver 1.3 has these tags: s1ap8_i3, s1ap8_i2, s1ap8_i1, jwsdp_12__02, jwsdp_12__01, TOMCAT_5_0_2, TOMCAT_5_0_1) Thanks for you help.

RE: [OFF-TOPIC] Ant
You have things in the wrong order: ant doesn't over-ride in a later format. The first time a variable is defined, that's when it's set. For example: ... Will print out john. Therefore, in your example, all three will be read. When a variable is defined, it stays that way and usually (note: exceptions are and , see documentation) can't be changed.

RE: What version of tomcat am I using?
Thanks. However, isn't this only useful from _within_ the web application? I mean, I can only execute this method from within an executing web app (It's not a static method, therefore, the ServletContext needs to be instantiated by a running instance of Tomcat.) I need the tomcat version from a script _outside_ of tomcat. My script is an upgrade script, and thus probably isn't going to be executed from within the web application. Thanks for the attempt though.

Problems running pre-compiled JSP classes when in subdirectories
I originally posted this question back in mid-December, but without any responses. In the hopes that someone will have a hit or a solution, I'm reposting the question again. I'm having a problem when I try to use my pre-compiled JSP files: I receive a NoClassDefFoundError exception. Here's what I'm doing ... I have pre-compiled my JSP classes using the JspC plugin from ant. My files compile without complaint. However, when I try to access the files through tomcat, I receive some NoClassDefFoundError exceptions. But these exceptions only occur when I'm accessing JSPs in the subdirectories off of the web root. Here's my application's background. I have two files: /index.jsp /dir/index.jsp The contents of the two files are just simple HTML. I precompiled the JSP using the JspC ant target, then compiled using javac. Finally, I created a context pointing the work directory to the location of my java and class files. When I tried to access the first file (http://localhost/context/index.jsp) everything went fine. However, when I tried to access the second file (http://localhost/context/dir/index.jsp), I received the NoClassDefFoundError. The log file looks like this: 2003-12-15 20:11:25 StandardWrapperValve[jsp]: Servlet.service() for servlet jsp threw exception javax.servlet.ServletException: org/apache/jsp/index_jsp (wrong name: org/apache/jsp/dir/index_jsp) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:249) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) [deleted ...] - Root Cause - java.lang.NoClassDefFoundError: org/apache/jsp/index_jsp (wrong name: org/apache/jsp/dir/index_jsp) at java.lang.ClassLoader.defineClass0(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:537) at java.lang.ClassLoader.defineClass(ClassLoader.java:448) at org.apache.jasper.servlet.JasperLoader.loadClass(JasperLoader.java:215) [deleted] Now, according to my research on this mailing list, the most frequent reason for a NoClassDef error is capitalization. However, this isn't the case in my situation as the two package names are completely different: org/apache/jsp/index_jsp vs. org/apache/jsp/dir/index_jsp. I'm using Tomcat 4.1.29. Any suggestions on how to alleviate this situation would be greatly appreciated. Thanks JDG PS: I should also point out that I have tried the recommended way of precompiling my JSP by converting to servlets (http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jasper-howto.html#Web%2 0Application%20Compilation). However, I have a problem with this method: it makes it that much harder to patch my application. With the non-servlet approach, I just simply deliver the modified JSP files. With the servlet approach, I need to deliver the classes, plus ensure that the web.xml is correct (add new entries, remove old ones, modify where needed), plus restart the context. -- Jay Glanville - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Thanks Yoav.
In my defense, I did perform a search. However, NOT in my defense, my

searching the archives for 'docbase'? Not a good word to limit by. ;-)
