I am a beginner to web application. I created a web application and the root folder is OBMS within which i had subfolders JSP, SRC, WEB-INF. In WEB-INF i had CLASSES,LIB folder and WEB.XML file. I placed a mysqlconnector jar file in the LIB folder since i am using mysql database with jsp. Then i created the war file OBMS.WAR with this contents. When i extracted this war file in another system, things are working except the jar file in the LIB folder is not identified. Should that jar file be mentioned in WEB.XML or any other procedure. Pls,Let me know.
Actually, I recommend placing database driver jars in the Tomcat/common/lib directory and not in the webapp. Firstly because it makes things a little more portable and second because it makes the driver available to any other webapps as well. However, to make classes in a jar usable by a webapp (assuming you don't place them in a shared lib directory), the place to put them is WEB-INF/lib. Capitalization is critical. It's not WEB-INF/Lib or WEB-INF/LIB or even Web-Inf/lib. Windows lets you be sloppy with filename capitalization, but Java doesn't. So the full path would be something like: C:\Tomcat4\webapps\mywebapp\WEB-INF\lib\mysql-connector.jar
