[jira] [Commented] (CONNECTORS-1243) Several NoClassDefFoundError
error if web apps are deployed to tomcat
[ https://issues.apache.org/jira/browse/CONNECTORS-1243?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14841451#comment-14841451 ]
Karl Wright commented on CONNECTORS-1243:
-----------------------------------------
Hi [~jan0sch], have you followed instructions about pointing tomcat at the proper properties.xml file using the proper -D switch?
The concern I have based on your description is that you are attempting to run a mixed 2.x and 1.x version. fuzzyml is found in mcf-connector-common.jar in 2.x, and in mcf-core.jar in 1.x. It's deployed in connector-common-lib in 2.x, and is loaded via a class loader.

> Hi,
> I've just compiled the current 2.2 release using {{ant make-core-deps make-deps build}} and deployed the 3 WAR files into a tomcat server. After running {{org.apache.manifoldcf.crawler.InitializeAndRegister}} the database seemed to be populated and the web ui seemed workable.
> However, on certain occasions a {{java.lang.NoClassDefFoundError}} is thrown.
> I've looked into {{WEB-INF/lib}} and didn't find the needed classes in any of the jar files there. On the other hand copying the jars into tomcats {{lib}}, {{common}} or {{shared}} directories didn't help either. :-(
