Read cache content from database issue

[laocui]

Hi All,

I deployed Modeshape3.8+infinispan5.3  in jboss EAP 6.3. 
I can store cache contents into database, but couldn't read it from another java application.

The follow is stack trace.

Caused by: java.lang.ClassCastException: java.lang.String cannot be cast to org.jboss.marshalling.Externalizer

Is there someone can help me?. thanks

Regarding the exception how do you get/put the entries, could you show examples?

If you use EAP6 (in production ) with a subscription you need to have JDG to be supported.

@Wolf-Dieter Fink  Thanks for your reply. What's the JDG ?

I used EAP6.3 alpha version.

I can upload a jar(which contains xml, properties and jbpm files) to Modeshape engine.
Infinispan is modeshape's cache store, will store contents to database.

Then I wrote following method to read content from database, but throw above exception when initialize repository

          public static void main(String[] args) {

                Properties props = new Properties();

                props.put(JcrRepository.MODE_SHAPE_CONFIG_URL, "classpath:modeshape-repository-config.json");

                Repository repository = new JcrRepository(props);               

               assert repository != null;

                Resource resources = repository.listFirstResource("jcr:routes.xml");

               assert resources != null;

          }

The attached standalone.xml is my configuration with JBOSS EAP 6.3.

Both modehspae-repository-config.json and infinispan-config.xml are used in java application.
