what happened to http://java.sun.com/xml/ns/j2ee/ ? Looks broken.
application.xml containing the above name space (Java 2 Platform, Enterprise Edition (J2EE) : XML Schemas for J2EE Deployment Descriptors) has not worked since this AM. The XML comes back invalid. However, Java EE: XML Schemas for Java EE Deployment Descriptors seem fine. application.xml referring to the second one is fine.
Any idea why? The first link seem partially broken.
This is a pretty serious concern. Weblogic server may not start. "appc" processes are broken and so on.
