问题描述

Enviornment- wildfly-9.0.2.Final，EJB 3.0

Enviornment- wildfly-9.0.2.Final, EJB 3.0

尝试连接Test.java类时（以wildfly-9.0部署为模块）发生以下错误。 2.Final@machine-A）到机器B（291.861.301.732）上的EJB部署在EJB上。

Test.java类中存在Test.java类testclient.jar已经被deplyed作为模块使用命令

Test.java class is present in testclient.jar & testclient.jar has been deplyed as a module using command

module add --name=testclient --resources=/Downloads/lib/test/client/testclient.jar --dependencies=javax.api

Test.java类



Test.java class

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://291.861.301.732:4447");
        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();}
}}

为什么这个错误已经发生了，为了可见性的org.jboss.naming.remote.client.InitialContextFactory到testclient.jar，我必须要添加更多的依赖项（目前只有javax。 api），同时将testclient.jar部署为模块？或任何其他导致错误的问题？ $ wilDFLY_HOME / bin / client / jboss-client.jar中的org.jboss.naming.remote.client.InitialContextFactory类也存在

why this error has been occurred, For visiblity of 'org.jboss.naming.remote.client.InitialContextFactory' to testclient.jar, should i have to add more dependencies(currently only javax.api) while deploying testclient.jar as a module? or any other issue which is causing error? Class 'org.jboss.naming.remote.client.InitialContextFactory' is also present in $WILDFLY_HOME/bin/client/jboss-client.jar

注 - 291.861.301.732是远程系统ip，其中ejb部署在jboss上。 ，这个ejb是使用JNDI从Test.java（远程客户端）调用的。

Note - 291.861.301.732 is the remote system ip, on which ejb is deployed at jboss. ,This ejb is invoking from Test.java(remote client) using JNDI.

在wildfly-9.0.2.Final中没有jnp（在JBOSS 5中） x），所以我将属性org.jnp.interfaces.NamingContextFactory替换为值org.jboss.naming.remote.client.InitialContextFactory，为什么还会出现错误？

There is no jnp in wildfly-9.0.2.Final(which was in JBOSS 5.x), so i replaced property "org.jnp.interfaces.NamingContextFactory" to value org.jboss.naming.remote.client.InitialContextFactory". why still error is occurred?

接收到评论后添加以下内容尝试将jboss-client.jar放在运行时路径中，作为WEB-INF / lib的一部分，或许可以通过Sampada Wagde

我无法理解，在这个场景中，test.jsp（在test.ear - > test.war - > test.jsp中）文件正在调用Test.java的函数getDbConnection文件Test.java文件存在于testclient.jar中，此testclient.jar已经被部署为一个模块
根据你的建议，当我将'jboss-client.jar'放在test.ear - > test.war - > WEB-INF - > lib，问题解决了，现在正在访问
应用程序'org.jboss.naming.remote.client.InitialContextFactory'ClassNotF ound异常没有发生... 但我的问题是有多个war的文件（Eg..test.war，test1.war，test2.war），每个war文件正在访问Test.java文件（存在于testclient.jar），所以我必须将'jboss-client.jar'文件放在每个war档案的WEB-INF / lib文件中。这对我来说非常复杂，有没有其他方法可用？其次，将'jboss-client.jar'放入WEB-INF / lib目录中，这个问题是通过'org.jboss.naming'来解决的。 remote.client.InitialContextFactory'存在于testclient.jar（不在test.ear - > test.war中）

I am not able to understand, In this scenarion test.jsp (present in test.ear-->test.war-->test.jsp) file is calling function getDbConnection of Test.java file. Test.java file is present in testclient.jar and this testclient.jar has been deployed as a module. As per your suggestion, when i put 'jboss-client.jar' in test.ear-->test.war-->WEB-INF-->lib, problem was solved, now while accessing application 'org.jboss.naming.remote.client.InitialContextFactory' ClassNotFound exception was not occurred...But my problem is that there are multiple war's files(Eg..test.war,test1.war,test2.war) and each war file is accessing Test.java file(present in testclient.jar), so i have to put 'jboss-client.jar' file in WEB-INF/lib of each war archive. which will be very complex for me, is there any other approach available? and secondly how this problem is solved by putting 'jboss-client.jar' into WEB-INF/lib direcory as 'org.jboss.naming.remote.client.InitialContextFactory' is present in testclient.jar(Not in test.ear-->test.war).

接收后添加以下内容在运行时，服务器需要回复'jboss-client.jar''''Sampada Wagde'

我还尝试了以下步骤
1.将'jboss-deployment-structure.xml'放在test.ear中 - > META-INF - > jboss-deployment-structure.xml

I also tried following steps 1. By putting 'jboss-deployment-structure.xml' in test.ear-->META-INF-->jboss-deployment-structure.xml

<?xml version="1.0"?>
<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.1">
<deployment>
    <dependencies>
        <module name="testclient" export="true" />
        <module name="jboss-client" export="true" />
    </dependencies>
</deployment>


  1. 将模块名称部署为

  1. Deploying module name as

module add --name=jboss-client --resources=/Downloads/wildfly-9.0.2.Final/bin/client/jboss-client.jar


但仍然出现以下错误。

推荐答案

您需要使自己的模块依赖于不仅包含jboss-client jar的模块，还包含jboss-client的所有依赖关系可能只是其他的模块，也可能是其他罐子。关于丢失的第一个类是javax / naming / spi / InitialContextFactory，因此编辑jboss-client模块的module.xml以依赖于javax.api

You need to make your own module depend on a module that contains not only the jboss-client jar, but also all the dependencies of jboss-client, this might just be other modules or possibly other jars too. The first class it's moaning about being missing is javax/naming/spi/InitialContextFactory so edit the module.xml for the jboss-client module to depend on javax.api
