无法激活SimpleNamingContextBuilder:已经有一个JNDI提供程序注册了

Question

通过ant脚本运行单元测试用例报告时出现以下错误:

Cannot activate SimpleNamingContextBuilder: there is already a JNDI provider registered. Note that JNDI is a JVM-wide service, shared at the JVM system class loader level, with no reset option. As a consequence, a JNDI provider must only be registered once per JVM.
java.lang.IllegalStateException: Cannot activate SimpleNamingContextBuilder: there is already a JNDI provider registered. Note that JNDI is a JVM-wide service, shared at the JVM system class loader level, with no reset option. As a consequence, a JNDI provider must only be registered once per JVM.

代码:

 this.callerContext = (CallerContext) getApplicationContext().getBean("CallerContext");
 assertNotNull(this.callerContext);
 SimpleNamingContextBuilder builder =    
 SimpleNamingContextBuilder.emptyActivatedContextBuilder();

Junit目标:

<junit printsummary="on" fork="yes" forkmode="perBatch" haltonfailure="false" failureproperty="junit.failure" showoutput="false">
    <classpath>
        <path refid="CLASSPATH_JUNIT"/>         
    </classpath>
    <batchtest fork="no"  todir="${TEST_BUILD_DIR}">
       <fileset dir="${APP_DIR_CORE}srctest">
          <include name="**/*Test.java" />
          <include name="**/Test*.java" />
       </fileset>
    </batchtest>
</junit>

Answer 1

我在Hibernate配置文件中启用了JNDI数据源，这会导致2个JNDI引用和如何JNDI/JVM绑定异常。
