Your application does not care - at least at this stage - whether it is accessed via IE or any other browser.
When your servlet is accessed, either through the init method or through post/get methods, you want your database to be connected to ; consequently you provide the servlet a driver class, in the present case a driver that implements xmldb with Xindice. If you want your servlet to be able to load this driver, it must first find it. Depending on the java dev kit you use, several locations are possible. In tomcat, a standard location can be webapps/your_application/WEB_INF/lib But other places are possible, for instance for tomcat-4.1.12 : $TOMCAT_HOME/shared/lib. You can also start tomcat with a script that provides a class path containing this driver class.
