一步一步jboss 7.1最终jndi属性文件的创建

我已经在我的机器上运行了juno和jboss AS 7.1,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(事实上,它与Enterprise Java Beans 3.1第6版中的完全相同)。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,该示例提到了“使用我们假设在类路径上提供的标准jndi.properties文件”(这是我的第一个问题,我不知道这是什么意思是,我实际上做了一些研究,但我不太明白它是如何工作的,让我困惑,最终似乎无法使它发挥作用。)

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。属性文件工作以及如何设置它。 (我读到了最后一期的问题,我得到了下面的.txt文件并将其扩展名更改为.jar,我不知道这是不对的):

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.jar文件放入类路径中(不知道我是否做得对:严格点击项目,构建路径,库,添加外部jar)。

我做了以上所有事情,但我一直得到以下内容:

javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file:  java.naming.factory.initial

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

AS7有一个全新的远程ejb / jndi实现,这意味着你不能再使用jnp了。

看看https://docs.jboss.org/author/display/AS71/EJB+invocations+from+a+remote+client+using+JNDI

https://docs.jboss.org/author/display/AS71/Remote+EJB+invocations+via+JNDI+-+EJB+client+API+or+remote-naming+project

您可以在那里找到如何操作的说明。

检查jndi.properties文件中的命名提供程序URL。 它应该是jnp://localhost:1099
