[jira] [Issue Comment Edited] (CONNECTORS-388) Upgrade the Crawler
UI framework with Apache Velocity
[ https://issues.apache.org/jira/browse/CONNECTORS-388?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13188743#comment-13188743 ]

------------------------------------------------------------------
I'm refactoring the root build.xml to build up the manifest classpath a line at a time, so we'll have to merge that when the time comes. Other than that, good work!
The reason that VelocityEngine doesn't find the resources is because they can only be accessed by the current classloader, which is defined in ManifoldCF core as a ordered list of classloaders. You can get a new classloader based on the current list by using the method ManifoldCF.createResourceLoader().
But preferably, if you use the local connector's Messages.class.getClassLoader(), you'll get the class loader used to load the local connector's Messages class. This is typically the right classloader. That's why I created these classes, so there'd be an easy way to do it.

The reason that VelocityEngine doesn't find the resources is because they can only be accessed by the current classloader, which is defined in ManifoldCF core as a nested set of classloaders. But you can get the correct classloader using the method ManifoldCF.createResourceLoader().
