Websphere（和Weblogic / JBoss）中的远程EJB查找(Remote EJB lookup in Websphere (and Weblogic/JBoss))

 我有一个用于搜索的EJB类， 
 
@Local(ILuceneEmployeeSearchManagerLocal.class)
@Remote(ILuceneEmployeeSearchManagerRemote.class)
public class LuceneEmployeeSearchManager implements ILuceneEmployeeSearchManagerLocal, ILuceneEmployeeSearchManagerRemote{
....
}
 
 同一个EAR中的WAR项目中还有另一个类，可以访问它， 
 
public class EmployeeAccessor {

    private ILuceneEmployeeSearchManagerRemote searcher;

    public EmployeeMstAccessor() {

        Context ic = null;
        try {
            Properties props = new Properties();
            props.put(Context.INITIAL_CONTEXT_FACTORY, "<WHAT_TO_PUT_HERE>");
            props.put(Context.PROVIDER_URL, "iiop://127.0.0.1:9083");
            ic = new InitialContext(props);
            this.searcher = (ILuceneEmployeeSearchManagerRemote) ic
                .lookup("<WHAT_TO_PUT_HERE?>");
        } catch (Exception e) {
            e.printStackTrace();
            throw new RuntimeException(e);
        }
    }

    ....

}
 
 当我使用JNDI执行本地查找时，这非常有效。 由于某些要求，现在需要在多个AP中部署EAR（在群集和非群集环境中）。 此外，所使用的应用程序服务器在AP之间是相同的，但不一定是Websphere，即所有AP都可能使用JBoss / Websphere / Weblogic。 
 
 我的问题是有一种独立于实现的查找和调用远程EJB的方法吗？ 适用于Websphere，Weblogic或JBoss环境（同构环境）的东西。 
 
 我的第二个问题是假设AP服务器正在运行Websphere（在集群或非集群环境中），比如说我希望所有AP服务器中的EmployeeAccessor都使用部署在AP01中的LuceneEmployeeSearchManager EJB（ip：xxxx，port：yy），我该如何配置？ 是否有必要提供完整的JNDI名称（包括websphere的单元名称和节点名称）？ INITIAL_CONTEXT_FACTORY的正确值是什么？ 什么是正确的JNDI查找语法？ 
 
 感谢您的任何帮助 ：） 

I have a EJB class that is used for searching,
 
@Local(ILuceneEmployeeSearchManagerLocal.class)
@Remote(ILuceneEmployeeSearchManagerRemote.class)
public class LuceneEmployeeSearchManager implements ILuceneEmployeeSearchManagerLocal, ILuceneEmployeeSearchManagerRemote{
....
}
 
There is another class in a WAR project in the same EAR, which accesses this,
 
public class EmployeeAccessor {

    private ILuceneEmployeeSearchManagerRemote searcher;

    public EmployeeMstAccessor() {

        Context ic = null;
        try {
            Properties props = new Properties();
            props.put(Context.INITIAL_CONTEXT_FACTORY, "<WHAT_TO_PUT_HERE>");
            props.put(Context.PROVIDER_URL, "iiop://127.0.0.1:9083");
            ic = new InitialContext(props);
            this.searcher = (ILuceneEmployeeSearchManagerRemote) ic
                .lookup("<WHAT_TO_PUT_HERE?>");
        } catch (Exception e) {
            e.printStackTrace();
            throw new RuntimeException(e);
        }
    }

    ....

}
 
This is working perfectly, when I was performing local lookups using JNDI. Due to some requirements, it is now necessary to deploy the EAR in multiple APs, (both in clustered and non-clustered environments). Also, the application server used will be same across APs, but not necessarily Websphere, i.e all of the APs may be using JBoss/Websphere/Weblogic. 
 
My question is there an implementation independent way of looking up and invoking remote EJBs ? Something that will work for Websphere, Weblogic or JBoss environments (homogeneous environments).
 
My second question is assuming the AP servers are running Websphere (in clustered or non-clustered environment), say I want EmployeeAccessor in all of the AP servers to be using the LuceneEmployeeSearchManager EJB deployed in AP01 (ip:x.x.x.x, port:yy), how do I configure it ? Is it necessary to give the full JNDI name (including cell name and node name for websphere) ? What are the proper values for INITIAL_CONTEXT_FACTORY ? and what is the correct JNDI lookup syntax ?
 
Thank you for any help :)
