Since we should be using jaxb for metadata that is annotated with it, and I see that you can use jaxb even when its not annotated, I'm looking at that instead. For metadata like the datasource which does have jaxb annotations: | public void testJaxbMCFXml() | throws Exception | { | ManagedConnectionFactoryDeploymentGroup mcfs = initMCFDG(); | | JAXBContext ctx = JAXBContext.newInstance(ManagedConnectionFactoryDeploymentGroup.class); | Marshaller marshaller = ctx.createMarshaller(); | marshaller.setProperty("jaxb.formatted.output", Boolean.TRUE); | QName mcfsName = new QName("datasources"); | JAXBElement<ManagedConnectionFactoryDeploymentGroup> root = new | JAXBElement<ManagedConnectionFactoryDeploymentGroup>(mcfsName, | ManagedConnectionFactoryDeploymentGroup.class, mcfs); | marshaller.marshal(root, System.out); | } | with initMCFDG() populating the mcfs similar to that shown above, jaxb output produces: | <?xml version="1.0" encoding="UTF-8" standalone="yes"?> | <datasources> | <local-tx-datasource> | <rar-name>jboss-local-jdbc.rar</rar-name> | <use-java-context>true</use-java-context> | <connection-definition>conn def</connection-definition> | <jmx-invoker-name>jboss:service=invoker,type=jrmp</jmx-invoker-name> | <min-pool-size>1</min-pool-size> | <max-pool-size>100</max-pool-size> | <blocking-timeout-millis>5000</blocking-timeout-millis> | <idle-timeout-minutes>15</idle-timeout-minutes> | <prefill>true</prefill> | <background-validation>true</background-validation> | <background-validation-millis>5000</background-validation-millis> | <validate-on-match>true</validate-on-match> | <statistics-formatter>org.jboss.resource.statistic.pool.JBossDefaultSubPoolStatisticFormatter</statistics-formatter> | <isSameRM-override-value>false</isSameRM-override-value> | <depends>jboss:service=Naming</depends> | <depends>jboss:service=Hypersonic,database=localDB</depends> | <metadata> | <type-mapping>Hypersonic SQL</type-mapping> | </metadata> | <local-transaction/> | <user-name>user</user-name> | <password>password</password> | <new-connection-sql>run this on a new conn</new-connection-sql> | <check-valid-connection-sql>select something from somewhere</check-valid-connection-sql> | <exception-sorter-class-name>org.jboss.jdbc.SomeExceptionSorter</exception-sorter-class-name> | <prepared-statement-cache-size>50</prepared-statement-cache-size> | <share-prepared-statements>false</share-prepared-statements> | <set-tx-query-timeout>false</set-tx-query-timeout> | <query-timeout>30000</query-timeout> | <use-try-lock>0</use-try-lock> | <driver-class>org.jboss.jdbc.SomeDriver</driver-class> | <connection-url>jdbc:xyz:a=b</connection-url> | <connection-property name="cp1-name">cp1-value</connection-property> | <connection-property name="cp2-name">cp2-value</connection-property> | </local-tx-datasource> | </datasources> | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4181724#...
