我无法设置我的jndi.properties来访问Jboss 5上的远程EJB

Question

我正在尝试设置Jboss服务器"客户端"(版本5.1.0)以使用来自另一个Jboss服务器(10.90.0.91)的远程EJB,但我不能使用Jboss客户端上的jndi.properties文件来执行此操作.

我可以在客户端上使用这个简单的代码获取远程EJB:

        InitialContext ctx = null;
        try {
            Hashtable<String, String> jndiProps = new Hashtable<String, String>();
            jndiProps.put(InitialContext.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
            jndiProps.put(InitialContext.PROVIDER_URL, "jnp://10.90.0.91:1099");
            ctx = new InitialContext(jndiProps);
            return ctx.lookup(jndiName);
        } catch (NamingException e) {
            throw new RuntimeException(e);
        }

这很好用.

现在我想用这个属性设置Jboss客户端.但是,如果我编辑本地化的现有jndi.properties文件server/{application}/conf/:

# DO NOT EDIT THIS FILE UNLESS YOU KNOW WHAT YOU ARE DOING
#
java.naming.factory.initial=org.jboss.iiop.naming.ORBInitialContextFactory
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces

至:

# DO NOT EDIT THIS FILE UNLESS YOU KNOW WHAT YOU ARE DOING
#
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.provider.url=jnp://10.90.0.91:1099

当我启动Jboss客户端时,我收到一些错误(显然,我不知道我在做什么:)):

2016-08-19 10:17:41,645 ERROR [org.jboss.kernel.plugins.dependency.AbstractKernelController] (main) Error installing to Start: name=HASessionStateService state=Create

在决赛中:

2016-08-19 10:17:51,993 ERROR [org.jboss.system.server.profileservice.ProfileServiceBootstrap] (main) Failed to load profile: Summary of incomplete deployments (SEE PREVIOUS ERRORS FOR DETAILS):

DEPLOYMENTS MISSING DEPENDENCIES:
  Deployment "ProfileServiceInvocationHandler" is missing the following dependencies:
    Dependency "ProfileServiceProxyFactory" (should be in state "Configured", but is actually in state "**ERROR**")
    Dependency "ProfileServiceProxyFactory" (should be in state "Configured", but is actually in state "**ERROR**")

DEPLOYMENTS IN ERROR:
  Deployment "jboss:service=ClientUserTransaction" is in error due to the following reason(s): javax.naming.NameAlreadyBoundException: UserTransaction

  Deployment "ProfileServiceProxyFactory" is in error due to the following reason(s): javax.naming.NameAlreadyBoundException: ProfileService, **ERROR**

所以,我想我无法触及该文件中已存在的JNDI属性.

如果jndi.properties文件由于JBoss本身使用而无法更改,那么在哪个位置将我的JNDI查找设置放到Jboss 5中的远程EJB中？如何在应用程序类路径中配置jndi.properties文件,而不将jndi.properties文件放在WAR文件中？

谢谢!

org.jboss.naming.ExternalContext另一种方法是在 jboss-service.xml 文件中配置 MBean ：

<mbean code="org.jboss.naming.ExternalContext" 
       name="jboss.jndi:service=ExternalContext,jndiName=external/server2">
    <attribute name="JndiName">external/server2</attribute>
    <attribute name="Properties">
        java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
        java.naming.provider.url=jnp://10.90.0.91:1099
        <!-- other properties as needed -->
    </attribute>
    <attribute name="InitialContext"> javax.naming.IntialContext </attribute>
    <attribute name="RemoteAccess">false</attribute>
</mbean>

执行查找的 java 代码将变为：

 Context initialContext = new InitialContext();
 return initialContext.lookup("external/server2/" + jndiName);

设置后，您甚至可以使用本地管理控制台中的 JNDIView 导航远程 JNDI 树。

更多信息可以在org.jboss.naming.ExternalContext MBean中找到。
