$CATALINA_HOME/lib Filip

Hello, I've setup my tomcat 6.0.13 with the CATALINA_HOME=/opt/tomcat and CATALINA_BASE=/opt/webBaseDir on a FC6 system. I read in http://tomcat.apache.org/tomcat-6.0-doc/class-loader-howto.html "Common - This class loader contains additional classes that are made visible to both Tomcat internal classes and to all web applications. Normally, application classes should NOT be placed here. All unpacked classes and resources in $CATALINA_HOME/lib, as well as classes and resources in JAR files are made visible through this class loader." and in http://tomcat.apache.org/tomcat-6.0-doc/config/loader.html "The description below uses the variable name $CATALINA_HOME to refer to the directory into which you have installed Tomcat 6, and is the base directory against which most relative paths are resolved. However, if you have configured Tomcat 6 for multiple instances by setting a CATALINA_BASE directory, you should use $CATALINA_BASE instead of $CATALINA_HOME for each of these references." and in conf/catalina.properties "# List of comma-separated paths defining the contents of the "common" # classloader. Prefixes should be used to define what is the repository type. # Path may be relative to the CATALINA_HOME or CATALINA_BASE path or absolute. # If left as blank,the JVM system loader will be used as Catalina's "common" # loader. # Examples: # "foo": Add this folder as a class repository # "foo/*.jar": Add all the JARs of the specified folder as class # repositories # "foo/bar.jar": Add bar.jar as a class repository common.loader=${catalina.home}/lib,${catalina.home}/lib/*.jar" and also in org/apache/catalina/startup/Bootstrap.java " while ((i=repository.indexOf(CATALINA_HOME_TOKEN))>=0) { replace=true; if (i>0) { repository = repository.substring(0,i) + getCatalinaHome() + repository.substring(i+CATALINA_HOME_TOKEN.length()); } else { repository = getCatalinaHome() + repository.substring(CATALINA_HOME_TOKEN.length()); } } while ((i=repository.indexOf(CATALINA_BASE_TOKEN))>=0) { replace=true; if (i>0) { repository = repository.substring(0,i) + getCatalinaBase() + repository.substring(i+CATALINA_BASE_TOKEN.length()); } else { repository = getCatalinaBase() + repository.substring(CATALINA_BASE_TOKEN.length()); } }" And finally in the RUNNING.txt file "In many circumstances, it is desirable to have a single copy of a Tomcat binary distribution shared among multiple users on the same server. To make this possible, you can pass a "-Dcatalina.base=$CATALINA_BASE" argument when executing the startup command (see (2)). In this "-Dcatalina.base=$CATALINA_BASE" argument, replace $CATALINA_BASE with the directory that contains the files for your 'personal' Tomcat instance." The behavior I've seen is that on startup, the jar files in CATALINA_HOME/lib are loaded before CATALINA_BASE/lib. Is that correct? I've seen that I must have the distributed jar files in CATALINA_HOME/lib, but for my "personal" tomcat, I have to put the jar files in CATALINA_BASE/lib. Are the documentation pages for all of the class loading inconsistant? Do I need to add to the catalina.properties file "common.loader=${catalina.home}/lib,${catalina.home}/lib/*.jar,${catalina.base}/lib,${catalina.base}/lib/*.jar" ? What is the correct place for the "Common" jars to get loaded with a multiple tomcat instances? I'm a little confused. Thanks.
