Bonjour, My apologies if you receive this message a second time. Even after I read the class loader documentation ( <http://jakarta.apache.org/tomcat/tomcat-4.0-doc/class-loader-howto.html> http://jakarta.apache.org/tomcat/tomcat-4.0-doc/class-loader-howto.html), the startup documentation ( <http://jakarta.apache.org/tomcat/tomcat-4.0-doc/RUNNING.txt> http://jakarta.apache.org/tomcat/tomcat-4.0-doc/RUNNING.txt - chapter 4 Advanced Configuration - Multiple Tomcat 4 Instances ) and mailing list archive, I am still stuck with the following problem : I choose to run Tomcat 4.0.4 like a WIN2K service with a specific base folder ($CATALINA_BASE different than $CATALINA_HOME) to have one tomact binary install an many tomcat running instances to deploy different versions of my WebApps (I set the different ports for the the connectors in each "CATALINA_BASE\conf\server.xml." configuration file) . But no specialized folder like "$CATALINA_BASE/lib" is used by the "Shared Class loader" to share classes across ALL the web applications running in ONE Tomcat instance. Is the unique solution is to copy my shared jar archive in each "<webapp>/WEB-INF/lib folder" ? How must I do to test several versions of the couple "xerces/xalan" ? If I replace the xerces.jar archive in the folder "$CATALINA_HOME\common\lib", all the Tomcat instances use the same parser ! I read also the doc "Class Loader HOW-TO" of Tomcat 4.1 and the same limitation exists, no ? The capability offered by the specialized folder "$CATALINA_HOME\common\endorsed" does not solve the problem ! Will it be possible that the class loader "Common" and "Shared" look if the folders "$CATALINA_BASE\common\lib", "$CATALINA_BASE\common\endorsed" or "$CATALINA_BASE\lib" exist ? If these folders exist, than the present jar files are loaded BEFORE those stored in the folder "$CATALINA_HOME\common\lib", "$CATALINA_HOME\common\endorsed" or "$CATALINA_HOME\lib" Thanks in advance for all your responses.

The context used to defined one WIN2K service corresponding to one Tomcat instance: set CATALINA_HOME=C:\Program Files\Apache Tomcat 4.0 set CATALINA_BASE=D:\+X3WebGarp\Adonix\X3Web\SERVERS_BASE set JAVA_HOME=C:\jdk1.3.1_03 set JAVA_OPTS=-Dadonix.x3web.install.approot="D:\+X3WebGarp\data" set JAVA_OPTS=%JAVA_OPTS% -Dadonix.x3web.install.progroot="D:\+X3WebGarp\Adonix\X3Web" set JAVA_OPTS=%JAVA_OPTS% -Dadonix.x3web.install.serverbase="%CATALINA_BASE%" set JAVA_OPTS=%JAVA_OPTS% -Djava.library.path="D:\+X3WebGarp\Adonix\X3Web\JNI\X3IMPDLL" Olivier Gattaz Adonix - Les Essarts - Z.A.
