    JTA vs. Non-JTA

      I'm referring to this bug on JBoss AS7: https://hibernate.onjira.com/browse/HHH-6522

       

      The problem is I can't use JTA as I always get a NullPointerException trying to create an EntityManager object. But without JTA nothing is written to my database table using Object.persist()

       

      How do I change this context to Non-JTA correctly? As this is only a development and no productive instance my server runs locally.

       

      Here's my datasource conf:

      <datasource jndi-name="HttpTestDS" pool-name="OracleDS" enabled="true" jta="false" use-java-context="true" use-ccm="true">
                    <connection-url>
                        jdbc:oracle:thin:@localhost:1521:xe
                    </connection-url>
                    <driver>
                        oracle
                    </driver>
                    <pool>
                        <prefill>
                            true
                        </prefill>
                        <use-strict-min>
                            false
                        </use-strict-min>
                        <flush-strategy>
                            FailingConnectionOnly
                        </flush-strategy>
                    </pool>
                    <security>
                        <user-name>
                            XYZuser
                        </user-name>
                        <password>
                            XYZpassword
                        </password>
                    </security>
                </datasource>

       

      ...and my persistence.xml...

      <persistence version="2.0" 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_2_0.xsd">
    <persistence-unit name="Interfaces_HTTP_ESP_Test_PersistencePU" transaction-type="RESOURCE_LOCAL">
        <non-jta-data-source>java:/HttpTestDS</non-jta-data-source>
        <mapping-file>META-INF/orm.xml</mapping-file>
            
                   
        <properties>            
            <property name="openjpa.DataCache"                value="true"/>         
            <property name="openjpa.RemoteCommitProvider"     value="sjvm"/>
            <property name="openjpa.DynamicEnhancementAgent"  value="false"/>
            <property name="openjpa.RuntimeUnenhancedClasses" value="unsupported"/>

            <property name="openjpa.jdbc.SynchronizeMappings" value="buildSchema(ForeignKeys=true)"/>
            <property name="openjpa.jdbc.QuerySQLCache"       value="true(EnableStatistics=true)"/>
        </properties>
    </persistence-unit>
</persistence>

      .

       

      and just in case if you need that too: orm.xml

       

      <?xml version="1.0" encoding="UTF-8"?>
<entity-mappings version="2.0" 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 http://java.sun.com/xml/ns/persistence/orm_2_0.xsd">
    <entity class="com.wn.csq.interfaces.httpesptest.persistence.dbentities.Debriefing">
    </entity>
    <entity class="com.wn.csq.interfaces.httpesptest.persistence.dbentities.Dbeta">

    <entity class="com.wn.csq.interfaces.httpesptest.persistence.dbentities.Dbline">

    <entity class="com.wn.csq.interfaces.httpesptest.persistence.dbentities.Dbnote">

    <entity class="com.wn.csq.interfaces.httpesptest.persistence.dbentities.Task">
    </entity>
    <entity class="com.wn.csq.interfaces.httpesptest.persistence.dbentities.Tasklogging">

    <entity class="com.wn.csq.interfaces.httpesptest.persistence.dbentities.Extservprov">

    <entity class="com.wn.csq.interfaces.httpesptest.persistence.dbentities.Tooluser">
    </entity>
    <entity class="com.wn.csq.interfaces.httpesptest.persistence.dbentities.Role">
    </entity>
</entity-mappings>

       

      Hope that you understand my problem and thanks in forward for your answer!
