使用JNDI将Bean插入JBoss [英] Plug Bean to JBoss with JNDI

问题描述

我想知道如何使用JNDI将对象（如果需要EJB）可以插入到JBoss（5.0）中？

我的Spring中有以下bean定义 applicationContext.xml ：

 < bean id =transactionManagerclass =org.springframework.orm .jpa.JpaTransactionManager> 
< property name =entityManagerFactoryref =entityManagerFactory/> 
< / bean> 
 
< tx：注释驱动的transaction-manager =transactionManager/> 
 
< context：annotation-config /> 
 
< bean id =myServiceFacadeclass =org.springframework.jndi.JndiObjectFactoryBean> 
< property name =jndiNamevalue =MyServiceFacadeBean / remote/> 
< property name =cachevalue =true/> 
< property name =lookupOnStartupvalue =true/> 
< property name =jndiEnvironment> 
<道具> 
< prop key =java.naming.factory.initial> org.jnp.interfaces.NamingContextFactory 
< / prop> 
< prop key =java.naming.provider.url> localhost：1099< / prop> 
< prop key =java.naming.factory.url.pkgs> org.jboss.naming：org.jnp.interfaces 
< / prop> 
< / props> 
< / property> 
< property name =proxyInterfacevalue =my.company.service.facade.MyServiceFacade/> 
< / bean> 
  

当我尝试运行JBoss时，我得到：

导致：javax.naming.NameNotFoundException：MyServiceFacadeBean / remote
在org.jboss.ha.jndi.HAJNDI.lookup远程（HAJNDI.java:264）
在org.jboss.ha.jndi.HAJNDI.lookup（HAJNDI.java:205）

at sun.reflect.NativeMethodAccessorImpl.invoke（NativeMethodAccessorImpl .java：39）
at sun.reflect.DelegatingMethodAccessorImpl.invoke（DelegatingMethodAccessorImpl.java:25）
在java.lang.reflect.Method.invoke（Method.java:597）
at $ org
$ / $ $ $ $ $ >

也许应该使用JBoss / JNDI注册对象的其他步骤？注意，我已经尝试将ejb特定的文件放到JBoss（jboss.xml，ejb-jar.xml）中，但这并不有用。

解决方案

如何在DataSource中循环远程？但是我确信你不能从你的MyServiceFacadeBean获取它。

在applicationContext.xml中：

 < property name =jndiNamevalue =remote/> 
  

尽管放开，

  Context ctx = new InitialContext（）; 
 DataSource ds =（DataSource）ctx.lookup（java：comp / env / remote）; 
 DataSource ds =（DataSource）envCtx.lookup（remote）; 
  

或者你可以做一个中间步骤，所以你不必指定java：comp / env 对于您检索的每个资源：

 上下文ctx = new InitialContext（）; 
上下文envCtx =（Context）ctx.lookup（java：comp / remote）; 
 DataSource ds =（DataSource）envCtx.lookup（remote）; 
  

希望有帮助。

I wonder how object (if it matter I need EJB) can be plugged to JBoss (5.0) with JNDI?

I have following bean definition in my Spring applicationContext.xml:

<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>

<tx:annotation-driven transaction-manager="transactionManager" />

<context:annotation-config/>

<bean id="myServiceFacade" class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiName" value="MyServiceFacadeBean/remote"/>
    <property name="cache" value="true"/>
    <property name="lookupOnStartup" value="true"/>
    <property name="jndiEnvironment">
        <props>
            <prop key="java.naming.factory.initial">org.jnp.interfaces.NamingContextFactory
            </prop>
            <prop key="java.naming.provider.url">localhost:1099</prop>
            <prop key="java.naming.factory.url.pkgs">org.jboss.naming:org.jnp.interfaces
            </prop>
        </props>
    </property>
    <property name="proxyInterface" value="my.company.service.facade.MyServiceFacade"/>
</bean>

when I try to run JBoss I get:

Caused by: javax.naming.NameNotFoundException: MyServiceFacadeBean/remote
at org.jboss.ha.jndi.HAJNDI.lookupRemotely(HAJNDI.java:264)
at org.jboss.ha.jndi.HAJNDI.lookup(HAJNDI.java:205)

at $Proxy165.lookup(Unknown Source)

Maybe some additional steps should be made for registering objects with JBoss/JNDI?

Note, I've tried already to put ejb specific files to JBoss (jboss.xml, ejb-jar.xml) but that doesn't help.

解决方案

How do you loop-up remote in your DataSource? But I am sure you can't get it from your MyServiceFacadeBean.

in applicationContext.xml:

<property name="jndiName" value="remote"/>

While loooping up,

Context ctx = new InitialContext();
DataSource ds = (DataSource)ctx.lookup("java:comp/env/remote");
DataSource ds = (DataSource)envCtx.lookup("remote");

or you could make an intermediate step so you don't have to specify "java:comp/env" for every resource you retrieve:

Context ctx = new InitialContext();
Context envCtx = (Context)ctx.lookup("java:comp/remote");
DataSource ds = (DataSource)envCtx.lookup("remote");

Hope it helps.
