Hello, I have a question related to class loading in tomcat.
http://tomcat.apache.org/tomcat-5.5-doc/class-loader-howto.html Tomcat documentation says this: *** Therefore, from the perspective of a web application, class or resource loading looks in the following repositories, in this order: Bootstrap classes of your JVM System class loader classses (described above) /WEB-INF/classes of your web application /WEB-INF/lib/*.jar of your web application $CATALINA_HOME/common/classes $CATALINA_HOME/common/endorsed/*.jar $CATALINA_HOME/common/i18n/*.jar $CATALINA_HOME/common/lib/*.jar $CATALINA_BASE/shared/classes $CATALINA_BASE/shared/lib/*.jar *** But while installing Jira (a popular web application for issue tracking), we seem to have observed different behaviour. We have set up a Tomcat instance for Jira (in some directory, lets call it CATALINA_BASE). Jira has a set of jar files that contain dependencies, that are not included in Jira's /WEB-INF/lib directory. Jira manual states that these jars should be copied to CATALINA_HOME/common/lib directory. When those files are copied to CATALINA_HOME/common/lib, Jira works fine. However, when we move those Jira dependencies from $CATALINA_HOME/common/lib/ to $CATALINA_BASE/shared/lib/ Jira starup fails - it throws several ClassDefNotFoundException (for org.postgresql.Driver and other classes) All this happened while the Jira instance was the only Tomcat instance on the server, and while $CATALINA_HOME/conf xml config files did not contain any entries specific for Jira or any other aplication other than those that come with Tomcat ba default. Accoring to what Tomcat help stated this should not be happening, because jar were only moved to another directory which is also included in the search path of the class loader. Does anyone know why is this happening? redhat 4.1 Java jdk1.5.0_07 Tomcat 5.5.x, probably 5.5.17 atlassian-jira-standard-3.6.3 -- Why? Because YES! --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
