    JTA vs. Non-JTA

    Patrick Schmitz Newbie

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

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

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