Test.jsp 正在调用 Test.java 类的 getDbConnection 方法。

测试.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

Test.java

package com.testmodule.pojo;

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");

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

访问测试时发生以下错误.jsp。

Following error occurred while accessing test.jsp.

我不想放em> jboss-client.jar 在Test.ear - > Test.war - > WEB-INF / lib中，因为有多个EAR可以访问Test.java 类。

I don't want to put jboss-client.jar in Test.ear --> Test.war --> WEB-INF/lib, as there are multiple EARs which will access Test.java class.

推荐答案

您尝试加载一些本地数据源时，您的JNDI代码用于远程调用。
您可以使用jboss-deployment-structure.xml文件在jboss客户端模块上添加依赖关系。

Your JNDI code is for remote call while you are trying to load some local datasource. You may add a dependency on the jboss client module with a jboss-deployment-structure.xml file.
