Konnte keine verwaltete Verbindung erhalten EJB, Hibernate, JBOSS, Postgr.

Question

Was kann ein Grund für diesen Fehler sein?

Meine Datenquelle als Modul enthalten und fällt in Ordnung, wenn ich nicht versuche, von dort nachzusehen. Das ist mein Fehler:

2016-11-04 15:57:55,389 ERROR [org.hibernate.engine.jdbc.spi.SqlExceptionHelper] (ServerService Thread Pool -- 74) javax.resource.ResourceException: IJ000453: Unable to get managed connection for java:jboss/datasources/PostgresDS 

Dieser mu standalone.xml ist:

    <datasource jta="true" jndi-name="java:jboss/datasources/PostgresDS" pool-name="PostgresDS" enabled="true" use-java-context="true"> 
       <connection-url>jdbc:postgresql://localhost:5433/cats</connection-url> 
       <connection-property name="cats"> 
        dictionary 
       </connection-property> 
       <driver>postgres</driver> 
       <pool> 
        <min-pool-size>1</min-pool-size> 
        <max-pool-size>20</max-pool-size> 
       </pool> 
       <security>

       </security> 
      </datasource> 
      <drivers> 
       <driver name="postgres" module="org.postgres"> 
        <xa-datasource-class>org.postgresql.xa.PGXADataSource</xa-datasource-class> 
        <datasource-class>org.postgresql.Driver</datasource-class> 
      </drivers> 

Das ist mein persistence.xml ist:

<?xml version="1.0" encoding="UTF-8"?> 

    <persistence version="2.1" 
     xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

     <property name="hibernate.flushMode" value="FLUSH_AUTO" /> 
     <property name="hibernate.hbm2ddl.auto" value="update" /> 
    </properties> 
</persistence-unit>

Answer 1

Wieder war es eine falsche XML-Konfigurationen. Ich habe meine Hibernate Einstellungen in persistance.xml geändert:

 <persistence version="2.1" 
    xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation=" 
http://xmlns.jcp.org/xml/ns/persistence 
http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd"> 
<persistence-unit name="postgres"> 
    <jta-data-source>java:jboss/datasources/PostgresDS</jta-data-source> 
    <!--Next (provider and dialect) are for version 9.4 and higher --> 
    <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider> 
    <properties> 
    <property name="hibernate.dialect"value="org.hibernate.dialect.PostgreSQL94Dialect" /> 
    <!-- this I comment because I already have my connection registered as a module 
    <property name="hibernate.connection.driver_class" value="org.postgresql.Driver" /> 
    <property name="hibernate.connection.url" value="jdbc:postgresql://localhost:5433/cats" /> 
    <property name="hibernate.connection.username" value="postgres" /> 
    <property name="hibernate.connection.password" value="mei" /> 
    Next I setup value of show_sql for false and hb2ddl.auto for "create-drop"--> 
    <property name="hibernate.show_sql" value="false"/> 
    <property name="hibernate.flushMode" value="FLUSH_AUTO" /> 
    <property name="hibernate.hbm2ddl.auto" value="create-drop" /> 
</properties>
