Since this works in conf/bootstrap-beans.xml | <bean name="ClassLoadingDefaultDeployer" class="org.jboss.deployers.plugins.classloading.ClassLoadingDefaultDeployer"> | <property name="defaultMetaData"> | | <!-- HERE --> | | <classloading xmlns="urn:jboss:classloading:1.0" export-all="NON_EMPTY" import-all="true"/> | </property> | </bean> | you need to explain what you are doing (or more likely not doing). This works in bootstrap-beans.xml because JBossXB knows not just where the schema is, but what to do with it. Where/how do you tell JBossXB what to do with that a schema called urn:jboss:security-config:5.0 e.g. look at deployers/metadata-beans.xml for where we tell it how to do javaee metadata parsing. NOTE: The error message is misleading urn:jboss:bean-deployer:2.0:property will take any element as a child what it is really telling you is that it doesn't know what to do with We know it found the schema (assuming that file exists in the classpath and is reachable from the bean parsing deployer's classloader): | TRACE [org.jboss.xb.binding.sunday.unmarshalling.DefaultSchemaResolver] (main) found schema InputSou | rce, nsURI=urn:jboss:security-config:5.0, baseURI=null, schemaLocation=resource:security-config_5_0. | xsd | OFF TOPIC Also, by tradition schemas are put in schema subfolders. i.e. it should be resource:schema/security-config_5_0.xsd The JBossEntityResolver will even look for this resource if you specify a proper schema location, e.g. http://www.jboss.org/schemas/security-config_5_0.xsd It strips the file name and tries to do getResource("schema/filename.xsd"); View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4138889#...
