Hi, I am an long-time JBoss AS 4 user and I having a bit of trouble deciphering my deployment issues on JBoss AS 5. What I am finding is that the JBoss specific deployment descriptors are causing the deployers to reject the deployments. The error that they are exhibiting is: Caused by: org.jboss.xb.binding.JBossXBRuntimeException: -1:-1 94:3 The markup in the document preceding the root element must be well-formed. | at org.jboss.xb.binding.sunday.unmarshalling.XsdBinderTerminatingErrorHandler.handleError(XsdBinderTerminatingErrorHandler.java:40) | at org.apache.xerces.impl.xs.XMLSchemaLoader.reportDOMFatalError(Unknown Source) | at org.apache.xerces.impl.xs.XSLoaderImpl.load(Unknown Source) | at org.jboss.xb.binding.Util.loadSchema(Util.java:395) | at org.jboss.xb.binding.sunday.unmarshalling.XsdBinder.bind(XsdBinder.java:175) | at org.jboss.xb.binding.sunday.unmarshalling.XsdBinder.bind(XsdBinder.java:146) | at org.jboss.xb.binding.sunday.unmarshalling.DefaultSchemaResolver.resolve(DefaultSchemaResolver.java:332) | ... 51 more I searched google and the JBoss community resources wiki/documentation/forums and the only reference I found to this indicates issues with poorly formed documents. However, I have checked the structure and validated the document with the specified DTD. An example document: <?xml version="1.0" encoding="UTF-8"?> | <!DOCTYPE jboss PUBLIC "-//JBoss//DTD JBOSS 2.4//EN" "http://www.jboss.org/j2ee/dtd/jboss_2_4.dtd"> | <jboss> | <enterprise-beans> | <session> | <ejb-name>MyBean</ejb-name> | <jndi-name>ejb/MyBean</jndi-name> | <resource-ref> | <res-ref-name>jdbc/EntityDB</res-ref-name> | <jndi-name>java:jdbc/EntityDB</jndi-name> | </resource-ref> | </session> | </enterprise-beans> | <resource-managers> | </resource-managers> | </jboss> Does anyone know why is JBoss 5 kicking this out? I have successfully deployed the application components by removing the DTD declarations altogether, but I'd really like to get to the root cause of the issue. Does JBoss 5 not support the legacy DTDs? If not, then why are they included in the docs/dtds directory of the installation? Any help will be greatly appreciated.
