> After some investigations it seems related to the updated velocity lib from
> velocity-1.7 to velocity-engine-core-2.3
> The first problem found is that the old velocity version libs and their
> dependencies are still present in the MCF build for the MCF Agent AND the
> mcf-crawler-ui.
> The concerned libs are:
> - commons-collections-3.2.2.jar
> - commons-lang-2.6.jar
> - velocity-1.7.jar
>
> The second problem is that with the new velocity version, the way to set
> properties to the engine has changed. So the code in the
> org.apache.manifoldcf.core.i18n.Messages.createVelocityEngine method is no
> longer valid and needs to be updated to fit with the new way which is:
> {code:java}
> VelocityEngine engine = new VelocityEngine();
> Properties configuration = new Properties();
> configuration.setProperty(VelocityEngine.RESOURCE_LOADER,"mcf");
> ....
> engine.setProperties(configuration); {code}
