predeploy for PersistenceUnit failed in JBOSS with toplink essentials

Question

When i am trying to deploy the product in jboss 5. I am using toplink-essentials for the JPA 1.0.

This product is running successfully on tomcat 6.

But in jboss it is showing errors.

I am trying to deploy the product through Eclipse IDE.

Error output :

Here is my persistence.xml file...

    </properties>

</persistence-unit>

I am using Struts 2.1.x, spring 1.2.x, jpa 1.0, toplink-essentials 2.0

Please help me to solve the problem...

Edited on 29/04/2013:

Hello Please any body can help me...

I can understand one thing, that there is some thing wrong in persistence.xml and it's data.

After so much googled, i had found some solutions.... like....

1) Remove the "private static final long serialVersionUID = 1L;" from all pojos.

2) There should not be white space in persistence.xml inside tag.

3) Change the JTA datasource from NON-JTA datasoucre.

I had changed all things as per the above mentioned points.

But still i am getting the same error.

My updated peresistence.xml is..

<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="Entity" transaction-type="JTA">

    <provider>oracle.toplink.essentials.PersistenceProvider</provider>

    <jta-data-source>java:/iport</jta-data-source>

    <class>env.model.masters.IptNotifications</class>
            <class>env.model.masters.IptNotificationslines</class>

            <properties>
                <property name="toplink.jdbc.driver"
                     value="com.microsoft.sqlserver.jdbc.SQLServerDriver" />
                <property name="toplink.jdbc.url"
                     value="jdbc:sqlserver://x.x.x.x:1433;databaseName=MyDatabase" />
                <property name="toplink.jdbc.user" value="xx" />
                <property name="toplink.jdbc.password" value="xx" />
            </properties>
    </persistence-unit>

</persistence>

Please verify the problem. and suggest me a possible solution.

I also have the orm.xml file.

The code is like below..

<?xml version="1.0" encoding="UTF-8"?>
<entity-mappings
xmlns="http://java.sun.com/xml/ns/persistence/orm"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/orm orm_2_0.xsd"
version="1.0">
<persistence-unit-metadata>

    <persistence-unit-defaults>

        <schema>MySchema</schema>

        <catalog>MyDatabase</catalog>

    </persistence-unit-defaults>

</persistence-unit-metadata>
</entity-mappings>

Please verify it

Answer 1

The error is occurring when TopLink Essentials is trying to load the default orm.xml file. Do you have one? Check that your file is valid and its namespace etc. are correct. If you don't have one, you could trying adding one.

Also try to upgrade to the latest TopLink Essentials patch release, or upgrade to EclipseLink, which replaced TopLink Essentials since 2008.

Answer 2

The exception doesn't explain much, but at least in Glassfish, transaction-type must be set to JTA instead of RESOURCE_LOCAL in the persistence.xml file, because as a full blown Java EE Application Server, it wants to have JTA transactions ready to use for EJB's and to inject container managed EntityManagers.

If that's also the problem with JBoss and you are using Spring, there are workarounds like changing the name of persistence.xml file to something else, so JBoss doesn't try to load the persistence unit that is already being handled by Spring.
