Question

我有一个用于测试的嵌入式ejb容器。在客户端（测试）我想使用查找机制获取DataSource。问题是查找方法总是返回错误：

javax.naming.NamingException：查找失败 'java：app / jdbc / templatedb'中 SerialContext [myEnv = {java.naming.factory.initial的= com.sun.enterprise.naming.impl.SerialInitContextFactory， java.naming.factory.state = com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl， java.naming.factory.url.pkgs = com.sun.enterprise.naming} [Root 异常是javax.naming.NamingException：调用异常：得到 null ComponentInvocation] at com.sun.enterprise.naming.impl.SerialContext.lookup（SerialContext.java:491）

的persistence.xml：

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

MyTest.java：

public class MyTest {

    @Test
    public void testAddNumbers() throws NamingException, EJBeanException{

        EJBContainer container = javax.ejb.embeddable.EJBContainer.createEJBContainer();

        DataSource ds = (DataSource)container.getContext().lookup("java:global/jdbc/templatedb");
        //DataSource ds = (DataSource)container.getContext().lookup("java:app/jdbc/templatedb");
        //DataSource ds = (DataSource)container.getContext().lookup("jdbc/templatedb");

    }
}

我尝试了不同的查找属性，但没有一个工作。有人有什么想法吗？
