解決方式:
在classpath內,加上%JBoss Home%\client\jbossall-client.jar

我用google找了很久,發現大多初次接觸開發EJB的人,都有遇到這個錯誤訊息,終於在今天我找到了真正可以解決的方法.希望能幫得上忙.

常见问题处理

当运行ConverterClient 时发现下面错误：

1. java.lang.ClassCastException
可能无法找到ConverterAppClient.jar文件。

2. java.lang.NoClassDefFoundError: ConverterClient
无法定位ConverterClient.class 文件。

3. java.lang.NoClassDefFoundError: javax/naming/Context
无法找到所需的j2ee.jar 文件，确认CLASSPATH设置。

4. javax.naming.NameNotFoundException: Lookup of name MyConverter failed.
J2EE服务器无法定位JNDI名字MyConverter所绑定的组件。

5. javax.naming.NamingException: Error accessing repository: Cannot connect to ORB at . . . .
J2EE服务器没有运行。
