RE: How to find Tomcat config and log path?
Setup your environment variable CATALINA_HOME (if you are using Windows, make sure it is a system environment rather than a user environment variable), and then use System.getenv(CATALINA_HOME); to get the tomcat path.

How to add -Djava.library.path to tomcat
Hi, I would like to load a library (.dll in windows and .so in linux) in a Java application, so I have to add the path of the library to LD_LIBRARY_PATH (Linux) or PATH (Windows). In addition, I also need to add -Djava.library.path=. However this is only for a standalone java application. But I'd like to deploy these applications as Axis web services, so how can I do the similar thing in Tomcat? i.e. how can I add -Djava.library.path in tomcat (in both Windows and Linux). Thanks Eric
Java Axis and R
Hi all, I've been asked to develop a Java Axis web service to call R program (http://www.r-project.org/). There is a Java/R interface (http://www.rforge.net/rJava/) has been developed and allows to call methods and access R object from Java. So my application is running fine as a normal Java application. However, it fails to run the R program when it is running as web service. Well from my experience, I guess the only reason to cause it was because Tomcat doesn't allow its own web applications to consume other programs that are not inside Tomcat. Similar situation happen before when I was trying to use System.getenv(CATALINA_HOME). It was running fine as a normal Java application, but doesn't work when it is running inside Tomcat. So does anyone know how to configure Tomcat to use other programs that are not inside Tomcat? By the way, the version of my tomcat is 5.5.23. Thanks in advance Kind Regards Eric Jiang

RE: mod_jk problem
Hi Rainer, Thanks for all your helps. I know that is a very outdated version of httpd, But since it is in a production server, and the server for the authentication of the whole university, so it is unlikely, or it is impossible for me to do any big change on it. And it is weird, because it is running completely fine in the test server which is the replication for the production server. So we are trying to reproduce the same error/bug that occurred in the production server, but unfortunately we still can't reproduce it. Any idea why?

RE: mod_jk problem
Hi Rainer, Yeah, I've look at the link that you sent to me in the last post. But again, it is in a production server; I don't really have the authority to make this change. According to your email, I've realized it is a very bad idea to this kind of log rotating, so I will suggest the system administrator to make some changes. But thanks again for all your helps. However we maybe end up to buying another server to host it. Thank you very much. Sincerely Eric -Original Message- From: Rainer Jung [mailto:[EMAIL PROTECTED] Sent: Tuesday, 22 May 2007 9:48 a.m. To: Tomcat Users List Subject: Re: mod_jk problem You really should totally drop the idea of rotating an open logfile from the outside. The file descriptor is open in the writing process and it will proceed to use the file descriptor, which will point to the rotated file and after compression will be deleted. Really a very bad idea. Usually if you need to rotate a log file from the outside, you need to take down the process during the rotation. If a process implements a signal or restart procedure, you can also send a signal or restart command after rotatting and before further manipulation on the file. Why aren't you simply using apache httpd rotatelogs, as suggested in my last post? http://httpd.apache.org/docs/2.0/programs/rotatelogs.html Regards, Rainer Yifan (Eric) Jiang wrote: Hi Rainer, Thanks for all your helps.
