我在Linux上運行帶有JDK 1.6的JBoss 5.1 GA並嘗試調用會話bean（包含此會話bean的jar部署在jboss服務器上），現在我想從客戶端調用這個會話bean，但沒有工作。從客戶端調用部署在jboss 5.x上的Bean
Java代碼的在客戶端
public class CallingJbossSessionBeanFromClient {
/**
* @param args
* @throws Exception
*/
public static void main(String[] args) throws Exception
{
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
p.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
p.put(Context.PROVIDER_URL, "jnp://182.158.93.41:8080");
Context context = new InitialContext(p);
System.out.println("Successfully Lookup and going to call SessionBean Function deployed on JBoss-5.1.0 Server");
SlsSessiongRemote remote=(SlsSessionRemote) context.lookup("SlsSessionBean/remote");
//SlsSessionBean/remote is RemoteBinding of session Bean
System.out.println("Called");
}
}
其中 'SlsSessionBean /遠程' 是遠程綁定部署JBoss服務器會話bean的。 @Stateless @RemoteBinding（jndiBinding = 「SlsSessionBean /遠程」）
但具有以下錯誤

最終看到上述錯誤i的 'CallingJbossSessionBeanFromClient' 的類路徑添加jbossjmx-的ant.jar後類和得到以下錯誤

上述錯誤看到i之後加入的「CallingJbossSessionBeanFromClient」類類路徑的jboss-測井spi.jar，並得到下面的錯誤

PLZ告訴我，我是從正確的方式調用客戶端Java類的sesion bean嗎？ 我花了數小時在Google上尋找解決方案。然而，我似乎無法找到任何握住手的東西..更清楚，我對這個問題缺乏創意，即使它聽起來像是一個經典的 PLZ建議解決方案
