Question

我有查询我的ejb的问题。在servlet中一切正常，但我需要从远程klient连接到ejb。

来自部署控制台日志：

 java:global/easymenu-webappEAR/EasyMenu/CounterBean!sk.jbase.projects.easymenu.CounterBeanRemote
 java:app/EasyMenu/CounterBean!sk.jbase.projects.easymenu.CounterBeanRemote
 java:module/CounterBean!sk.jbase.projects.easymenu.CounterBeanRemote
 java:jboss/exported/easymenu-webappEAR/EasyMenu/CounterBean!sk.jbase.projects.easymenu.CounterBeanRemote
 java:global/easymenu-webappEAR/EasyMenu/CounterBean
 java:app/EasyMenu/CounterBean
 java:module/CounterBean

我在webapp中有ejbmodule（我不知道它是如何分开的）

geting context：

public static InitialContext getInitialContext(String url) throws NamingException {
    Properties properties = new Properties();

    properties.setProperty(Context.URL_PKG_PREFIXES,
            "org.jboss.ejb.client.naming");
    properties.setProperty(Context.PROVIDER_URL, url);
    properties.setProperty(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
    properties.setProperty(Context.SECURITY_PRINCIPAL, "pch");
    properties.setProperty(Context.SECURITY_CREDENTIALS, "peterch");

    return new InitialContext(properties);
}

查询：

            CounterBeanRemote cbr = (CounterBeanRemote) ServiceLocator
                    .getInitialContext("remote://localhost:8080").lookup("java:app/EasyMenu/CounterBean!"
        + CounterBeanRemote.class.getName());

            System.out.println("Result: " + cbr.getMessage());

异常

你使用哪个JBoss版本？在JBoss 7.1中，默认远程端口是4447，您应该使用java：jboss / exported /之后的URL。如果您使用“org.jboss.ejb.client.naming”，则需要URL的“ejb：”前缀以及通常位于文件jboss-ejb-client.properties中的属性。

我在JBOSS AS 7.2的最后一夜构建中遇到了同样的问题。当我刚刚将类路径中的jboss-client.jar恢复为旧版本时，它开始像魅力一样工作。

修复上面的URL和查找以及jboss-client.jar后，应该这样做。

EJB查找 - 无法创建远程连接
