如何在Jboss 7中使用jndi数据源

Question

In Jboss 5 i used a datasource for a remote DB, something as:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<datasources>
    <local-tx-datasource>
         <jndi-name>dsName</jndi-name>
          ...
         <connection-url>jdbc:oracle:thin:@xxx:2074:xx</connection-url>
    </local-tx-datasource>
</datasources>

and i called from my applicationContext.xml in this way:

<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiName" value="java:dsName"/>
</bean>

it is possibile to do in Jboss7? In these posts JBoss 7.1 - declare datasource and access via JNDI https://developer.jboss.org/thread/196876

i have found that

Thanks

Answer 1

WildFly (and AS7) don't support remote datasource lookup, which I believe is a deliberate decision. If you used it on older versions where it worked, it was incredibly easy to create terrible performance problems, large server-side memory leaks, and more.

What was the use case for having one? The best option is usually to encapsulate the data logic in an EJB which does the DB work server-side, and then call it from the client.

That said I am not sure if you are actually trying to use "remote" datasource lookup. Check out the guides for datasource configuration basics.

Answer 2

i get

Error creating bean with name 'dataSource' defined in URL [file:... applicationContext.xml]: Invocation of init method failed; nested exception is javax.naming.CommunicationException: Failed to connect to any server. Servers tried: [remote://localhost:4447 (java.net.ConnectException: Connection refused: no further information)] at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1708)

it works only if i configure the datasource in this way:

        <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
           <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"/>
               <property name="url"  >
                  <value>...</value>
               </property>
               <property name="username"  >
                  <value>...</value>
               </property>
               <property name="password"  >
                  <value>...</value>
               </property>


         </bean>

without jndi, directly in applicationContext.xml

thanks
