[jboss-user] [Installation, Configuration & DEPLOYMENT] - Re: Maven + Embedded EJB + JPA +EJB 3.0 getting Null name
Took me a while to get this but here it is:
The persistence.xml should look almost exactly like below:
<persistence>
| <persistence-unit name="myPU">
| <jta-data-source>java:/MyDB</jta-data-source>
| <properties>
| <property name="hibernate.dialect"
value="org.hibernate.dialect.MySQLInnoDBDialect" />
| <property name="hibernate.hbm2ddl.auto" value="update"
/>
| </properties>
| </persistence-unit>
| </persistence>
Each tag should be in one single line with no line breaks. The Null name I was getting is
most likely a bug in parsing this persistence.xml file with line breaks.
Also, since I was coming from a toplink background I found that the data source has to be
name "java:/MyDB" as opposed to "jdbc/MyDB"
Then make sure you have the corresponding data source defined in embedded-jboss-beans.xml
as below
<bean name="MyDB"
class="org.jboss.resource.adapter.jdbc.local.LocalTxDataSource">
| <property
name="driverClass">com.mysql.jdbc.Driver</property>
| <property
name="connectionURL">jdbc:mysql://dev1:3306/mydb?user=root&password=hello</property>
| <property name="jndiName">java:/MyDB</property>
| <property name="transactionManager"><inject
bean="TransactionManager"/></property>
| <property name="cachedConnectionManager"><inject
bean="CachedConnectionManager"/></property>
| <property name="initialContextProperties"><inject
bean="InitialContextProperties"/></property>
| </bean>
|
Finally here is a method that will test your code:
| public void create() throws Exception {
| Owner owner = new Owner();
| OwnerData ownerData = new OwnerData();
| ownerData.setName("Test Company");
| ownerData.setContact("Richard");
| ownerData.setPhone("979-777-7777");
| owner.setOwnerData(ownerData);
|
| EJB3StandaloneBootstrap.boot(null);
| EJB3StandaloneBootstrap.scanClasspath();
|
| InitialContext ctx = getInitialContext();
|
| OwnerDAO dao = (OwnerDAO) ctx.lookup("OwnerDAOBean/local");
| dao.create(owner);
| EJB3StandaloneBootstrap.shutdown();
| }
I was having problems trying to get the lookup to work when the container was being
started by a BeforeGroups method. But I've save that for another post. Once you get it
all working it's pretty cool :)
