Atomikos Forum

Hi,

I'm new to this forum.  I'm working on a project that is trying to integrate Atomikos with Tomcat 8. So, my first question is, can I use Atomikos with Tomcat 8? 

This is the exception I'm seeing:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

SEVERE: Servlet.service() for servlet jsp threw exception
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/jasper/servlet/JasperLoader) of the current class, org/apache/jsp/WEB_002dINF/jsp/base/sitemesh_005fbase_005ftemplate_jsp, and the class loader (instance of java/net/URLClassLoader) for resolved class, org/apache/jasper/runtime/InstanceManagerFactory, have different Class objects for the type he.jasper.runtime.InstanceManagerFactory.getInstanceManager(Ljavax/servlet/ServletConfig;)Lorg/apache/tomcat/InstanceManager; used in the signature

While searching the forum I only saw references to Tomcat 7 and below. If this is already answered somewhere on the site, I apologize for re-posting.

Thanks in advance,

Hi,

AFAIK our built-in Tomcat integration (commercial feature for subscribers) works with Tomcat 8 too. I am not sure what you are trying but I recommend trying to find budget for a commercial subscription. Besides integrating Tomcat, that will also ensure proper startup and shutdown ordering so recovery is seamless.
