Question

我在Tomcat上的grails应用程序尝试调用GlassFish上的远程EJB

RemoteService.groovy

class RemoteService {

    static transactional = false

    static Bin bin;

    public ICallCenter getAction() throws NamingException {

        if (bin == null) {
            bin = new Bin("127.0.0.1","3700") // local!
        }

        try{
            return (IMyInterface)((bin.getInitialContext()).lookup("java:global/My-ear/My-ejb-1.0/MyBean"))
        } catch (java.rmi.MarshalException e){
            ...
        }
    }

}

Bin.java

public class Bin {

    private Properties props = new Properties();

    public Bin(String host, String port) {
        props.setProperty("java.naming.factory.initial", "com.sun.enterprise.naming.SerialInitContextFactory");
        props.setProperty("java.naming.factory.url.pkgs", "com.sun.enterprise.naming");
        props.setProperty("java.naming.factory.state", "com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl");
        props.setProperty("org.omg.CORBA.ORBInitialHost", host);
        props.setProperty("org.omg.CORBA.ORBInitialPort", port);

    }

    public InitialContext getInitialContext() throws NamingException {
        return new InitialContext(props);
    }

}

但它失败，但例外：

根据问题Error while using jersey-client in osgi - No generator was provided，我复制了 hk2-api.jar ， hk2-locator.jar ， hk2-utils.jar < / strong>， javax-inject.jar ， jersey-guava-2.6.jar 到tomcat / lib。但它没有帮助。 出了什么问题？

UPD： 在glassfish（位于同一主机上），我们有

@Remote public interface IMyInterface { ... } @Remote(IMyInterface .class) @TransactionManagement(TransactionManagementType.BEAN) @Stateless(mappedName = "MyBean") public class MyBean implements IMyInterface { .... }

缺少IntialContext课程，您应该在使用Bin初始化host, port时在 Bin.java 中尝试此操作。

  props.setProperty("org.omg.CORBA.ORBInitialHost", "127.0.0.1");
  props.setProperty("org.omg.CORBA.ORBInitialPort", "3700");
  InitialContext ctx = new InitialContext(props);
  SimpleBean bean = (SimpleBean) ctx.lookup(SimpleBean.class.getName());
  String result = bean.sayHello("Daniel Suarez Jabonete");
  oPrintWriter.println(result);

无法调用远程EJB：不提供生成器
