XML Schema Problem j2ee/schema jbxb_1_0.xsd line 19 src-resolve.4.2: Error resolving component 'jbxb:package'. It was detected that 'jbxb:package' is in namespace 'http://www.jboss.org/xml/ns/jbxb', but components from this namespace are not referenceable from schema document 'file:///C:/eclipse-workspace/SITData/j2ee/schema/jbxb_1_0.xsd'. If this is the incorrect namespace, perhaps the prefix of 'jbxb:package' needs to be changed. If this is the correct namespace, then an appropriate 'import' tag should be added to 'file:///C:/eclipse-workspace/SITData/j2ee/schema/jbxb_1_0.xsd'.
