Hi, Here is how one can reproduce the scenario:
1. Start Tomcat 2. Put attached war in webapps folder 3. In the console the following error message is printed: INFO: Deploying web application archive C:\apache-tomcat-7.0.25\webapps\test-web-app.war Feb 4, 2012 10:41:44 PM org.apache.catalina.util.ExtensionValidator validateManifestResources INFO: ExtensionValidator[/test-web-app][Web Application Manifest]: Required extension [test-jar] not found. Feb 4, 2012 10:41:44 PM org.apache.catalina.util.ExtensionValidator validateManifestResources INFO: ExtensionValidator[/test-web-app]: Failure to find [1] required extension(s). Feb 4, 2012 10:41:44 PM org.apache.catalina.core.StandardContext startInternal SEVERE: Error getConfigured Feb 4, 2012 10:41:44 PM org.apache.catalina.core.StandardContext startInternal SEVERE: Context [/test-web-app] startup failed due to previous errors 4. Stop Tomcat 5. Create folder - C:\apache-tomcat-7.0.25\ext 6. Put the attached jar file in the folder created on step 5 7. Start Tomcat with additional VM argument -Dcatalina.ext.dirs=C:/apache-tomcat-7.0.25/ext 8. This time the application is deployed successfully. 9. Request http://localhost:8080/test-web-app/TestServlet 10. Internal Server Error is returned with the following Exception: java.lang.ClassNotFoundException: test.TestExtension org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1701) org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1546) test.TestServlet.doGet(TestServlet.java:28) javax.servlet.http.HttpServlet.service(HttpServlet.java:621) javax.servlet.http.HttpServlet.service(HttpServlet.java:722) I did not change any other Tomcat configuration so it is running with defaults. The scenario is that TestServlet (in war file) instantiates TestExtension (in jar file, placed in the ext directory).
