Problem with ORM by Weblogic

[Thomas Chang]

Hi all,

I create an EJB-Project which runs quite well in JBoss. Now I am going to deploy it by Weblogic Express 10g. But I have problem by deploying. I got Exception as follow:

    
Error processing persitence unit dwSpring2Jpa of module TestBEAEJB3Beans.jar: Error looking up a DataSource for PersistenceUnit dwSpring2Jpa: javax.naming.NameNotFoundException: Unable to resolve 'OracleDS'. Resolved ''; remaining name 'OracleDS'

My "persistence.xml" looks as follow:

    
<?xml version="1.0"?>
<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
    <a href="http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"" target="_blank" rel="nofollow">http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"</a>
version="1.0">
<persistence-unit name="dwSpring2Jpa">
<jta-data-source>OracleDS</jta-data-source>
<properties>
<property name="hibernate.hbm2ddl.auto" value="create-drop" />
</properties>
</persistence-unit>
</persistence>

My question: where should I locate the datasource descriptor which contains the OracleDS and the username and password?

Basically you need to create a Datasource in Weblogic. Since, how you do that is Weblogic specific, I am going to move this thread to the Weblogic forum

Thanks

Mark is correct. You need to create a weblogic DataSource and then you may check in JNDI tree if the DS is correct available.
You will find information on how to create a DS at:

You may also find the following links usefull:

Hi,

I did create a DataSource via AdminConsole in Weblogic. I gave the DataSource a Name "dwSpring2Jpa". Then I gave the "JNDI Name" a value of "OracleDS". My database name is XE.

In the "persistence.xml" I have:

  
...
<persistence-unit name="dwSpring2Jpa">
<jta-data-source>OracleDS</jta-data-source>
...

I am somewhat confused if I set the values correct or not.

The problem of connection to the database is solved.
