Question

我在为EJB3和wildfly运行远程客户端时遇到错误。我的ejb看起来像波纹管。

    package com.tst.ejb;

    import javax.ejb.LocalBean;
    import javax.ejb.Stateless;

    /**
     * Session Bean implementation class TestWLDFly
     */
    @Stateless
    @LocalBean
    public class TestWLDFly implements TestWLDFlyRemote {

        /**
         * Default constructor. 
         */
        public TestWLDFly() {
            // TODO Auto-generated constructor stub
        }

        @Override
        public void TestPrint() {
            // TODO Auto-generated method stub

        }
  }

远程接口如下

package com.tst.ejb;

import javax.ejb.Remote;

@Remote
public interface TestWLDFlyRemote {

    public void TestPrint();
}

远程客户端如下......

package com.tst.ejb;

import java.util.Hashtable;
import java.util.Properties;

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;

import org.jboss.ejb.client.ContextSelector;
import org.jboss.ejb.client.EJBClientConfiguration;
import org.jboss.ejb.client.EJBClientContext;
import org.jboss.ejb.client.PropertiesBasedEJBClientConfiguration;
import org.jboss.ejb.client.remoting.ConfigBasedEJBClientContextSelector;

public class EJBClient {

    public static void main(String[] args) throws NamingException {

            final Hashtable<String, Object> jndiProperties = new Hashtable<>();

            Properties p = new Properties();
            p.put("remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED", "false");
            p.put("remote.connections", "one");
            p.put("remote.connection.one.port", "8080");
            p.put("remote.connection.one.host", "localhost");

            EJBClientConfiguration cc = new PropertiesBasedEJBClientConfiguration(p);
            ContextSelector<EJBClientContext> selector = new ConfigBasedEJBClientContextSelector(cc);
            EJBClientContext.setSelector(selector);

            Properties props = new Properties();
            props.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
            InitialContext context = new InitialContext(props);


            final String rcal = "ejb:/TSTWLDFLY/TestWLDFly!com.tst.ejb.TestWLDFlyRemote";
            final TestWLDFlyRemote remote = (TestWLDFlyRemote) context.lookup(rcal);

            remote.TestPrint();


    }

}

Wildfly日志显示JNDI名称如下所示

java:global/TSTWLDFLY/TestWLDFly!com.tst.ejb.TestWLDFlyRemote
java:app/TSTWLDFLY/TestWLDFly!com.tst.ejb.TestWLDFlyRemote
java:module/TestWLDFly!com.tst.ejb.TestWLDFlyRemote
java:jboss/exported/TSTWLDFLY/TestWLDFly!com.tst.ejb.TestWLDFlyRemote

java:app/TSTWLDFLY/TestWLDFly!com.tst.ejb.TestWLDFly
java:module/TestWLDFly!com.tst.ejb.TestWLDFly

我运行客户端时遇到异常。

我尝试了所有JNDI名称。可能是我做错了什么。任何帮助表示赞赏。

您不应使用@LocalBean注释。它使得无法远程访问此EJB。只需删除它。

给出EJBCLIENT000025的ejb远程客户端：没有可用于处理错误的EJB接收器
