Spring, configure the DataSource through JNDI having remote JBoss Server
提问by Talha Ahmed Khan
I want to make DataSourcein Springthrough JNDI. All the configuration are given.
我想要DataSource在Spring通过JNDI。所有的配置都给出了。
Can someone tell me what is wrong with the configuration.
有人能告诉我配置有什么问题吗？
One thing I would like to mention here is that JNDI DS is hosted on JBoss server which does not host the Springapplication.
我想在这里提到的一件事是 JNDI DS 托管在不托管Spring应用程序的JBoss 服务器上。
Configuration
配置

I have made few changes and Its now working fine.
我做了一些更改，现在工作正常。
A JNDI Template must be initialized with the JNP properties. And URL to JBoss server has to be in that properties.
JNDI 模板必须使用 JNP 属性进行初始化。JBoss 服务器的 URL 必须在该属性中。
configContext.xml
配置上下文.xml
<bean id="wcJndiTemplate" class="org.springframework.jndi.JndiTemplate">
<property name="environment">
<props>
<prop key="java.naming.factory.initial">org.jnp.interfaces.NamingContextFactory</prop>
<prop key="java.naming.provider.url">jnp://jndi.myURL.me:1099</prop>
<prop key="java.naming.factory.url.pkgs">org.jboss.naming:org.jnp.interfaces</prop>
<prop key="jnp.disableDiscovery">true</prop>
</props>
</property>
</bean>
<bean id="wcDataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="jdbc/wc-mysql"/>
<property name="resourceRef" value="false"/>
<property name="jndiTemplate" ref="wcJndiTemplate" />
</bean>
But after doing that changes I was facing an exception
但是在做了这些改变之后，我遇到了一个例外
java.lang.ClassNotFoundException: org.jnp.interfaces.NamingContextFactory
So I found a link mentioning to include a dependency of jbossall-client.jarin the POM to resolve the issue. So the pom changes are
所以我发现一个链接提到jbossall-client.jar在 POM 中包含一个依赖项来解决这个问题。所以 pom 的变化是
<dependency>
<groupId>jboss</groupId>
<artifactId>jbossall-client</artifactId>
<version>4.2.2.GA</version>
</dependency>
Every thing seems to be working fine.
一切似乎都运转良好。
Thanks.
谢谢。

There is no problem with your remote JNDIas this line
你的遥控器没有问题，JNDI因为这条线
<use-java-context>false</use-java-context>
will take care of it.
会照顾它。
You have problem with your JNDI name value:
您的 JNDI 名称值有问题：
javax.naming.NameNotFoundException: Name jdbc is not bound in this Context
Change this in your applicationConfig.xml
在你的 applicationConfig.xml
<property name="jndiName" value="jdbc/wc-mysql" />
to
到
<property name="jndiName" value="java:/jdbc/wc-mysql"></property>
It should work
它应该工作
