All,

I have been working on a very simple EJB 3 sample setup for myself and am working on the persistence setup for testing simple data storage via an EntityManager. The problem is that I am unable to connect to the internal HSQL database using my configurations. I would appreciate if someone could help me out.

The following are the steps I took to attempt this database setup:

1. Install JBoss w/ the JEMS Installer (using all the defaults)
2. Start the server
3. Drop my Ejb3Example-ds.xml file into the deploy folde

<?xml version="1.0" encoding="UTF-8"?>

<datasources>

 <local-tx-datasource>
 <jndi-name>Ejb3ExampleDB</jndi-name>
 <connection-url>jdbc:hsqldb:${jboss.server.data.dir}${/}hypersonic${/}Ejb3ExampleDB</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>
 <track-statements />
 <security-domain>HsqlDbRealm</security-domain>

 <metadata>
 <type-mapping>Hypersonic SQL</type-mapping>
 </metadata>

 <depends>jboss:service=Hypersonic,database=Ejb3ExampleDB</depends>

 </local-tx-datasource>

 <!-- This mbean can be used when using in process persistent db -->
 <mbean code="org.jboss.jdbc.HypersonicDatabase"
 name="jboss:service=Hypersonic,database=Ejb3ExampleDB">
 <attribute name="Database">Ejb3ExampleDB</attribute>
 <attribute name="InProcessMode">true</attribute>
 </mbean>

</datasources>

4. Build my application source and package it into a Jar including my persistence.xml (sp?) file within the META-INF directory

<?xml version="1.0" encoding="UTF-8"?>

<persistence xmlns="http://java.sun.com/xml/ns/persistence"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"
 version="1.0">

 <persistence-unit name="Ejb3Example">

 <provider>org.hibernate.ejb.HibernatePersistence</provider>
 <jta-data-source>java:/Ejb3ExampleDB</jta-data-source>
 <properties>
 <property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect" />
 <property name="hibernate.hbm2ddl.auto" value="create-drop" />
 </properties>

 </persistence-unit>

</persistence>

5. Drop my Jar into the deploy folder with my DAO class set up as follows:

@Stateful
public class MyDaoBean implements MyDaoLocal, MyDaoRemote
{
 @PersistenceContext(unitName = "Ejb3Example")
 private EntityManager entityManager;

 private Logger logger;

 @PostConstruct
 public void init() {
 // attribute initialization
 logger = Logger.getLogger("Ejb3ExampleStorageManager");

 // core logging
 logger.info("EJB 3 Example storage initialized.");
 logger.info("Storage flush mode: " + entityManager.getFlushMode());
 }

 public void ping() {
 logger.debug("Object Storage Ping");
 }

 public void create(Serializable obj) {
 logger.info("Persis requested for " + obj.getClass().getName());
 entityManager.persist(obj);
 }

 public <T> T find(Class<T> objectType, UUID primaryKey) {
 logger.info("Lookup requested for " + objectType.getName() + "/" + primaryKey);
 return entityManager.find(objectType, primaryKey);
 }
}

The problems that I get are exceptions thrown apparently relating to authentication errors (larger stack trace available upon request):

...
org.jboss.resource.JBossResourceException: No matching credentials in Subject!
...
org.jboss.util.NestedSQLException: No matching credentials in Subject!; - nested throwable: (org.jboss.resource.JBossResourceException: No matching credentials in Subject!)
...
Caused by: org.jboss.resource.JBossResourceException: No matching credentials in Subject!
... etc.

What am I doing wrong?
