Hello list, I'm doing my first experiments with Tomcat and servlets. Here's my setup:
* Tomcat 5.5 runs on a Debian GNU/Linux 4.0 stable box and is installed via the packaging system (apt-get). * The following tomcat and sun-java related packages are installed: r...@clydet:~# dpkg --list | grep tomcat ii libtomcat5.5-java 5.5.20-2etch3 Java Servlet engine -- core libraries ii tomcat5.5 5.5.20-2etch3 Java Servlet 2.4 engine with JSP 2.0 support ii tomcat5.5-admin 5.5.20-2etch3 Java Servlet engine -- admin & manager web i ii tomcat5.5-webapps 5.5.20-2etch3 Java Servlet engine -- documentation and exa r...@clydet:~# dpkg --list | grep sun-java ii sun-java5-bin 1.5.0-14-1etch1 Sun Java(TM) Runtime Environment (JRE) 5.0 ( ii sun-java5-demo 1.5.0-14-1etch1 Sun Java(TM) Development Kit (JDK) 5.0 demos ii sun-java5-jdk 1.5.0-14-1etch1 Sun Java(TM) Development Kit (JDK) 5.0 ii sun-java5-jre 1.5.0-14-1etch1 Sun Java(TM) Runtime Environment (JRE) 5.0 ( ii sun-java5-source 1.5.0-14-1etch1 Sun Java(TM) Development Kit (JDK) 5.0 sourc * Apparently, with this install, i have the following .jar files available under /usr/share/java: r...@clydet:/usr/share/java# ls *servlet* servlet-2.3.jar servlet-api-2.4.jar servlet-api.jar These files contain for example the HttpServlet class: r...@clydet:/usr/share/java# jar tf servlet-api.jar | grep HttpServlet\.class javax/servlet/http/HttpServlet.class * I have a webapp running under http://host:8180/testbart/ * My webapp currently has the following files: r...@clydet:/webapps/testbart# find . ./WEB-INF ./WEB-INF/classes ./WEB-INF/classes/HelloServlet.class ./WEB-INF/lib ./WEB-INF/web.xml ./index.html The class file was compiled using javac 1.5.0_16. Notice also that there is no file in the lib directory. When i trie to access the servlet using the URL http://clydet:8180/testbart/helloworld I get java.lang.NoClassDefFoundError: javax/servlet/http/HttpServlet I can solve this problem by copying /usr/share/java/servlet-api.jar to the ./WEB-INF/lib directory and restarting my tomcat... but somehow this seems not the clean solution to me. I expected tomcat to have servlet-api.jar available in its classpath somehow, so that I don't need to copy this file for every webapp I have. My 2 questions are: 1) Is it necessary to copy servlet-api.jar to the WEB-INF/lib directory of every web application that i have? Or can i somehow tell tomcat that this file is located in /usr/share/java? 2) Is there a way to find out which classpath tomcat is using? And how does the classpath for tomcat gets setup?
