ClassNotFoundException：组织。jboss。命名。遥远的客户InitialContextFactory

Question

使用环境：

• WildFly 9.0.2。期末考试
• EJB 3.0
• 蚂蚁
• 日蚀

测验jsp正在调用测试方法。java类。

测验jsp

<%@page import="com.testmodule.pojo.Test"%>
<%
    try{
        System.out.println(" Going to call getDbConnection method of 'Test' class. This 'Test' class shall be "
            + " part of testclient.jar. testclient.jar shall be deployed as a module --- module add --name=testclient --resources=/Downloads/lib/test/testclient.jar");
        System.out.println(" test.jsp shall be present in test.ear...'jboss-deployment-structure.xml' shall be present in "
            + " in META-INF directory of test.ear with entry as -- <dependencies><module name=\"testclient\" export=\"true\" /> </dependencies>");
        System.out.println(" Dont want to put 'jboss-client.jar' in Test.ear-->Test.war-->WEB-INF/lib , As there are multiple ear's which are accessing Test.java class");

        new Test().getDbConnection();
    } catch(Exception e) {
        e.printStackTrace();
    }
%>

Test.java

package com.testmodule.pojo;

import java.util.Properties;
import javax.naming.Context;
import javax.naming.InitialContext;

public class Test { 
    public void getDbConnection(){
        try {
            Properties jndiProps = new Properties();

            jndiProps.put(Context.INITIAL_CONTEXT_FACTORY, 
                "org.jboss.naming.remote.client.InitialContextFactory");
            jndiProps.put(Context.PROVIDER_URL,"remote://29.86.30.73:4447");
            jndiProps.put(Context.SECURITY_PRINCIPAL, "testuser");
            jndiProps.put(Context.SECURITY_CREDENTIALS, "testpassword");
            jndiProps.put("jboss.naming.client.ejb.context", true);

            Context context = new InitialContext(jndiProps);
        } catch(Exception e) {
            e.printStackTrace();
        }
    }
}

访问测试时发生以下错误。jsp。

我不想让jboss-client.jarest.ear

您的JNDI代码用于在尝试加载某些本地数据源时进行远程调用。您可以使用jboss部署结构在jboss客户端模块上添加依赖项。xml文件。
