我在我的机器上运行了 eclipse juno 和 jboss AS 7.1 final 并通过它进行了配置（eclipse juno）。我有一个简单的无状态 bean 及其接口（实际上与 Enterprise Java Beans 3.1 6th Edition 书中的示例完全相同）。这是代码：
package beans;
public class CalculatorBeanBase implements CalculatorCommonBusiness{
public int add(int[] opers){
int sum = 0;
for(int c:opers){
sum+=c;
}
return sum;
}
}
package beans;
public interface CalculatorCommonBusiness {
public int add(int[] opers);
}
package beans;
public interface CalculatorRemoteBusiness extends CalculatorCommonBusiness {}
package beans;
import javax.ejb.LocalBean;
import javax.ejb.Stateless;
@Stateless
@LocalBean
public class SimpleCalculatorBean extends CalculatorBeanBase {}
我正在尝试进行以下 JUnit 测试，不幸的是，该示例提到“使用我们假设在类路径上呈现的标准 jndi.properties 文件”（这是我的第一个问题，我不知道这意味着什么，我事实上做了一些研究，但我不太明白它是如何工作的，让我感到困惑，最终似乎无法让它发挥作用）。
package beans;
import javax.naming.Context;
import javax.naming.InitialContext;
import junit.framework.TestCase;
import org.junit.BeforeClass;
import org.junit.Test;
public class CalculatorIntegrationTestCase {
private static Context namingContext;
private static SimpleCalculatorBean cal;
private static final String JNDI_NAME_CALC = "java:global/jndi.properties/SimpleCalculatorBean";
@BeforeClass
public static void obtainProxyReferences() throws Throwable {
namingContext = new InitialContext();
cal = (SimpleCalculatorBean)namingContext.lookup(JNDI_NAME_CALC);
}
private void assertAdditionSucceeds(SimpleCalculatorBean cal){
final int[] oper = {2,3,4};
final int expectedSum = 9;
final int actualSum = cal.add(oper);
TestCase.assertEquals("Assert Failed!!. The actual value is not the expected",expectedSum, actualSum);
}
@Test
public void testAdditionUsingBusinessReference() throws Throwable {
this.assertAdditionSucceeds(cal);
}
}
我需要知道那个jndi。属性文件的工作原理以及我必须如何设置它。（我阅读了最后一个问题，我得到了以下 .txt 文件并将其扩展名更改为 .jar，我不知道这是否正确）：
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.provider.url=jpn://localhost:1099
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
最后，我将该 .jar 文件放入类路径中（不知道我是否做得对：右击项目、构建路径、库、添加外部 jar）。
我做了以上所有的事情，但我不断得到以下内容：

当然，我发布了项目（尽管通过 eclipse，项目>运行>在服务器上运行）。帮助将不胜感激
