Could not create a new Tx

[rory8000]

Hi,

I'm trying to do some stuff with the JCR like create namespaces but I get this error:

javax.jcr.RepositoryException: Could not create a new Tx: BaseTransaction.checkTransactionState - [com.arjuna.ats.internal.jta.transaction.arjunacore.alreadyassociated] [com.arjuna.ats.internal.jta.transaction.arjunacore.alreadyassociated] thread is already associated with a transaction!: BaseTransaction.checkTransactionState - [com.arjuna.ats.internal.jta.transaction.arjunacore.alreadyassociated] [com.arjuna.ats.internal.jta.transaction.arjunacore.alreadyassociated] thread is already associated with a transaction!

Please help

Please describe more your issue. What is your code? What is your data source configuration?...

My gatein-ds.xml for jcr:

<local-tx-datasource>

      <jndi-name>gatein-jcr_portal</jndi-name>

      <connection-url>jdbc:hsqldb:${jboss.server.data.dir}${/}gatein${/}hypersonic${/}gatein-jcr_portal-localDB</connection-url>

      <driver-class>org.hsqldb.jdbcDriver</driver-class>

      <user-name>sa</user-name>

      <password></password>

      <min-pool-size>5</min-pool-size>

      <max-pool-size>20</max-pool-size>

      <idle-timeout-minutes>0</idle-timeout-minutes>

      <prepared-statement-cache-size>32</prepared-statement-cache-size>

   </local-tx-datasource>

My code:

     PortalContainer container = RootContainer.getInstance().getPortalContainer("ecmdemo");

     PortalContainer.setInstance(container);

     RepositoryService repositoryService = (RepositoryService) container.getComponentInstanceOfType(RepositoryService.class);

     repositoryService.setCurrentRepositoryName("repository");

     Repository repository = repositoryService.getCurrentRepository();

     Credentials cred = new SimpleCredentials("root","gtn".toCharArray());

     Session session = repository.login(cred, "collaboration");

     Workspace workspace = session.getWorkspace();

     //JCR Stuff

     workspace.getNamespaceRegistry().registerNamespace("myn", "mynamespace");

     session.logout();

Thanks

This is weird, anyway your code even if it worked would only register the namespace at Runtime so it is not enough. If you want to register a namespace and persist it, you will need to add it in your configuration file. In the next example, I register 2 namespaces with their corresponding prefixes.

What abou if I need to remove node types that I registered within the content manager.  Anyway, any operation for create, update or delete gave the previous error

I believe that your issue is not related to this, it is probably a consequence of a more general issue. Which product do you use? What is the exact version of it? Please provide the log file of your application server.
