Question

我正在使用Open JPA获得Exception。

我创建了WAS数据源。这是My Persistence XML

http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd“＆GT;

<persistence-unit name="App11" transaction-type="JTA">
<provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
<jta-data-source>java:comp/env/jdbc/mydatasource</jta-data-source>  
     <class>vo.Entity</class>
     <properties>
        <property name="openjpa.TransactionMode" value="managed"/>
                <property name="openjpa.ConnectionFactoryMode" value="managed"/>
    </properties>
    </persistence-unit>

我在执行时遇到此异常。

aused by：org.apache.commons.lang.exception.NestableRuntimeException：在JNDI查找名称“java：comp / env / jdbc / mydatasource”时出错。在org.apache.openjpa.lib.conf.Configurations.lookup（Configurations.java:592）在org.apache.openjpa.conf.OpenJPAConfigurationImpl.lookupConnectionFactory（OpenJPAConfigurationImpl.java:966）在org.apache.openjpa.conf.OpenJPAConfigurationImpl.getConnectionFactory（OpenJPAConfigurationImpl.java:954） at org.apache.openjpa.jdbc.conf.JDBCConfigurationImpl.createConnectionFactory（JDBCConfigurationImpl.java:801）在org.apache.openjpa.jdbc.conf.JDBCConfigurationImpl.getDBDictionaryInstance(JDBCConfigurationImpl.java:568）在org.apache.openjpa.jdbc.meta.MappingRepository.endConfiguration（MappingRepository.java:1221）在org.apache.openjpa.lib.conf.Configurations.configureInstance（Configurations.java:476）在org.apache.openjpa.lib.conf.Configurations.configureInstance（Configurations.java:401）在org.apache.openjpa.lib.conf.PluginValue.instantiate（PluginValue.java:102）在org.apache.openjpa.lib.conf.ObjectValue.instantiate（ObjectValue.java:82）在org.apache.openjpa.conf.OpenJPAConfigurationImpl.newMetaDataRepositoryInstance（OpenJPAConfigurationImpl.java:861）在org.apache.openjpa.conf.OpenJPAConfigurationImpl.getMetaDataRepositoryInstance（OpenJPAConfigurationImpl.java:852）在org.apache.openjpa.kernel.AbstractBrokerFactory.makeReadOnly（AbstractBrokerFactory.java:640）在org.apache.openjpa.kernel.AbstractBrokerFactory.newBroker（AbstractBrokerFactory.java:171）

任何帮助赞赏。

Answer 1

这是我的问题的解决方案......

我在web.xml中错过了这个

jdbc / Mysource javax.sql.DataSource Container Unshareable

Answer 2

尝试按Websphere Datasource with a given JNDI name?

中的建议在resource-ref中添加web.xml运行时描述符文件ibm-web-bnd.xml}

使用WAS 7.0 Java中的数据源打开JPA异常
