我有一个问题，ejb部署上去了
可是客户端（调试用的）运行有问题

源码：
import javax.naming.InitialContext;
import javax.rmi.PortableRemoteObject;
import java.util.*;
import javax.naming.*;

import org.jboss.docs.interest.Interest;
import org.jboss.docs.interest.InterestHome;

/** This simple application tests the 'Interest' Enterprise JavaBean which is
implemented in the package 'org.jboss.docs.interest'. For this to work, the
Bean must be deployed on an EJB server.
*/
class InterestClient
{
/** This method does all the work. It creates an instance of the Interest EJB on
the EJB server, and calls its `calculateCompoundInterest()' method, then prints
the result of the calculation.
*/
public static void main(String[] args)
{
// Enclosing the whole process in a single `try' block is not an ideal way
// to do exception handling, but I don't want to clutter the program up
// with catch blocks
try
{
// Get a naming context
     Properties properties = new Properties();
     properties.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
     properties.put(Context.PROVIDER_URL,"jnp://localhost:1099");
     //properties.put(Context.PROVIDER_URL_PKGS,"org.jboss.naming:org.jnp.interfaces");

InitialContext jndiContext = new InitialContext(properties);
System.out.println("Got context");

// Get a reference to the Interest Bean
Object ref = jndiContext.lookup("java:comp/env/ejb/Interest");
System.out.println("Got reference");

// Get a reference from this to the Bean's Home interface
InterestHome home = (InterestHome)
PortableRemoteObject.narrow(ref, InterestHome.class);

// Create an Interest object from the Home interface
Interest interest = home.create();

// call the calculateCompoundInterest() method to do the calculation
System.out.println("Interest on 1000 units, at 10% per period, compounded over 2 periods is:");
System.out.println(interest.calculateCompoundInterest(1000, 0.10, 2));
}
catch(Exception e)
{
System.out.println(e.toString());
}
}
}

运行结果:D:\Temp\jboss\testejb>java InterestClient
javax.naming.NoInitialContextException: Cannot instantiate class: org.jnp.interf
aces.NamingContextFactory [Root exception is java.lang.ClassNotFoundException: o
rg.jnp.interfaces.NamingContextFactory]

who can tell me why? thanks~

classpath 中包含 %jboss_home%/client/jbossall-client.jar

怎么还用到了 javax 下的 net 包

把 client 目录下的 jnet.jar 也加到 classpath 中

你的 classpath 还是有问题吧

D:\jboss-3.0.6;\server\default\lib\javax.servlet.jar
                --- 这个地方怎么多了个 ';'，其他很多地方都多了个 ';'

好像不是classpath的问题吧？

错误信息就是 jnp 的工厂类没有找到，它应该属于 jnp-client.jar 或者 jbossall-client.jar 这两个包里，你的 classpath 太复杂了，其实只留下

jbossall-client.jar,log4j.jar,jnet.jar,a.jar 这几个包就应该可以了

你试着用 javap org.jnp.interfaces.NamingContextFactory 看一看着各类再不在当前的 classpath 中，如果不在说明你的 classpath 还是有问题

hehe谢谢，已经没有这个问题了，但是又有了一个问题
D:\Temp\jboss\testejb\client>java InterestClient
Got context
javax.naming.NameNotFoundException: comp not bound

09:09:48,799 INFO [MainDeployer] Deployed package: file:/D:/jboss-3.0.6/server/
default/deploy/testejb.jar

看，我得ejb么已经部署上去了

这是我得jboss.xml
<?xml version="1.0" encoding="UTF-8"?>
<jboss>
<enterprise-beans>
<session>
<ejb-name>Interest</ejb-name>
<jndi-name>interest/Interest</jndi-name>
</session>
</enterprise-beans>
</jboss>

这是ejb-jar.xml
<?xml version="1.0" encoding="UTF-8"?>

<ejb-jar>
<description>JBoss Interest Sample Application</description>
<display-name>Interest EJB</display-name>
<enterprise-beans>
<session>
<ejb-name>Interest</ejb-name>
<home>org.jboss.docs.interest.InterestHome</home>
<remote>org.jboss.docs.interest.Interest</remote>
<ejb-class>org.jboss.docs.interest.InterestBean</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Bean</transaction-type>
</session>
</enterprise-beans>
</ejb-jar>

comp是什么意思，请教～～

当你的程序运行在 container 环境中的时候 java:comp 才需要

当你的程序运行在客户端的时候，直接使用

lookup("interest/Interest") 就可以了

在运行之前你可以访问

http://localhost:端口/jmx-console/

然后使用 service=JNDIView

点击最后的 list 下面的 invoke 看一看现在 jboss3 的 jndi 里面都有哪些对象

直接看最下面的 global 部分就可以了，看看有没 有 interest/Interest

如果有，那就说明部署成功了，调用应该就没有问题了

java:comp namespace of the Interest bean:
+- UserTransaction (class: javax.transaction.UserTransaction)
+- env (class: org.jnp.interfaces.NamingContext)

我的是testejb.jar
不在下面，在上面，请教为什么

+- interest (class: org.jnp.interfaces.NamingContext)
| +- Interest (proxy: $Proxy22 implements interface org.jboss.docs.interest.InterestHome,interface javax.ejb.Handle)

这不是有吗，你已经部署成功了，可以用

lookup("interest/Interest"); 找到了

但是运行客户端还是不行
