[ https://issues.jboss.org/browse/JBIDE-16096?page=com.atlassian.jira.plugi... ] Alexey Kazakov commented on JBIDE-16096: ---------------------------------------- The problem is that the corresponding tag libraries are not available for projects with WildFly runtime since WildFly classpath container includes a limited set of jars. To handle situations when the project does not have all needed tag libs in its classpath we bundle a few common libraries (<h:*>, <f:*>, etc) and register them via XMLCatalog. But we have a bug JBIDE-16859 with jst plugins packed in JARs so that is why the tests case from description works well in dev environment (plugins are not packed there) and fails in JBDS. So this issue is not about supporting new namespaces actually but about supporting XML Catalog with tag libs packed in JARs. This is not critical for Beta1, so I'm moving the issue to Beta2. -- This message is automatically generated by JIRA.
