+1 Netbeans is a great environment to work in and very easy to config BUT when adding any library it is important to know which classloader you will be using http://tomcat.apache.org/tomcat-5.5-doc/class-loader-howto.html System - generally for libraries utilised during Tomcat bootup Catalina - generally for libraries utilised by the Catalina container (you can configure in other webapp containers) Common - generally for libaries which will be commonly used for ALL webapps WEB-INF/lib - generally for libraries used for just the web application
When your app is looking for a class the search order is a.. Bootstrap classes of your JVM b.. System class loader classses (described above) c.. /WEB-INF/classes of your web application d.. /WEB-INF/lib/*.jar of your web application e.. $CATALINA_HOME/common/classes f.. $CATALINA_HOME/common/endorsed/*.jar g.. $CATALINA_HOME/common/i18n/*.jar h.. $CATALINA_HOME/common/lib/*.jar i.. $CATALINA_BASE/shared/classes j.. $CATALINA_BASE/shared/lib/*.jar if you experience difficulty loading a class its because the class is being used by either Tomcat or a webapp or both (its important to not load the same jar in more than one classloader path) HTH, Martin-- --------------------------------------------------------------------------- This e-mail message (including attachments, if any) is intended for the use of the individual or entity to which it is addressed and may contain information that is privileged, proprietary , confidential and exempt from disclosure.

In netbeans you can drop in your libs, make your JSP, debug it and deploy it. Good luck ----- Original Message ----- From: Evrim Agha To: Tomcat User Sent: Sunday, March 25, 2007 9:09 AM Subject: Question about lib folder of Webapps Hi everyone I'd like to build a JSP to use and show results of using Sparql + Jena + Pellet libraries. I have set up a directory called MyFirstTestDir in [TomcatDir]\webapps. Inside MyFirstTestDir, I have created a folder called WEB-INF which has a folder called lib; So I have: [TomcatDir]\webapss\MyFirstTestDir\WEB-INF\lib inside lib, I have copied all the files in lib folder of jena download + pellet download. Extremely appreciate your help with these questions: Some of the Jena jar files and Sparql jar files share the same name; therefore I can not copy them directly to lib. Could you please advise what should I do? I am using winxp and tomcat 6. Thank you in advance. ------------------------------------------------------------------------------ --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
