Re: how does the tomcat log generated? log4j?
2010/12/25 André Warnier a...@ice-sa.com The logging page which I pointed you to, does not say that Tomcat uses log4j. It says that you /can/ configure Tomcat to use log4j, instead of the default juli logging. It even provides instructions to do so. The AccessLogValve documentation page does not say either that it uses log4j. But what it does say at the very beginning, is that the output file is changed every day at midnight. So if you only read the files up to last night at midnight, you will never encounter the problem that something is still writing to it. Also, I do not know what your ultimate purpose is, but there exist already several open-source programs which read a logfile in the format produced by the Tomcat AccessLogValve, parse it, and produce nice graphical statistics out of it (like webalizer or awstats). Maybe you are re-inventing something which already exists ? Unfortunately yes,our boss want our own analyzer system based on java. :( Web access statistics are not usually something which needs to be accurate in real-time. Having Tomcat writing them directly to a database may have a noticeable impact on your applications performance. That's why this is something usually done off-line.

I'd like to have some auto-generated JSP code used in our system without writing it to disk in a directory in my webapp's real path. Is this possible? Thanks for any ideas... Yes.

processing of tlds failed -- application still works -- why?
Hi All, I am seeing the error below while deploying a web application on Tomcat 6.0.16. Note that the parser used for processing tlds is Crimson -- I expect Tomcat to use the default Xerces parser to process tlds, but it using Crimson parser that is in a jar in WEB-INF/lib. It seems this issue is related to bug 29936 fixed in 6.0.17: https://issues.apache.org/bugzilla/show_bug.cgi?id=29936 . I don't see this error on Tomcat 6.0.18. Question: My application works fine. The custom tags defined in the tld the parsing failed on still work. Why do the custom tags work when tld parsing failed? Can this error be ignored? What is the purpose of method processTlds?
