Hello Chris, As of today I figured out that the jasper.jar in Tomcat's \lib takes care of the task out of the box. I've tweaked my pom a few times, but I started fresh today and realized it. So no pom updates were necessary. Still I'm getting this exception I mentioned in the earlier e-mail:
Caused by: java.lang.LinkageError: loader constraint violation: when resolving method "org.apache.jasper.runtime.InstanceManagerFactory.getInstanceManager(Ljavax/servlet/ServletConfig;)Lorg/apache/tomcat/InstanceManager;" the class loader (instance of org/apache/catalina/loader/WebappClassLoader) of the current class, jsp/WEB_002dINF/jsp/home_005fpage_jsp, and the class loader (instance of java/net/URLClassLoader) for the method's defining class, org/apache/jasper/runtime/InstanceManagerFactory, have different Class objects for the type org/apache/tomcat/InstanceManager used in the signature at jsp.WEB_002dINF.jsp.home_005fpage_jsp._jspInit(home_005fpage_jsp.java:128) at org.apache.jasper.runtime.HttpJspBase.init(HttpJspBase.java:49) at org.apache.catalina.core.StandardWrapper.initServlet(StandardWrapper.java:1231) It does not happen on my current Tomcat7 deploy though.
