How do I configure a JDBC data source in JBoss AS 5.1.0.GA?

Question

Could somebody point me at or post an example of configuring a data source for JBoss 5.1.0.GA?

I am getting the following error when I try to hook up a data source to my web application in JBoss 5.1.0.GA using JNDI.

startup failed due to previous errors java.lang.RuntimeException: mapped-name is required for jdbc/jos of deployment jos-services-1.0.0-SNAPSHOT.war

My /WEB-INF/web.xml contains the following resource reference: 

<resource-ref>
    <res-ref-name>jdbc/jos</res-ref-name>
    <res-type>javax.sql.DataSource</res-type>
    <res-auth>Container</res-auth>
</resource-ref>

I have configured /META-INF/jboss-web.xml as follows: 

<?xml version="1.0" encoding="UTF-8"?>
<jboss-web
    xmlns="http://www.jboss.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
        http://www.jboss.com/xml/ns/javaee
        http://www.jboss.org/j2ee/schema/jboss-web_5_1.xsd"
    version="5.1">
    <context-root>/services</context-root>
    <resource-ref>
        <res-ref-name>jdbc/jos</res-ref-name>
        <res-type>javax.sql.DataSource</res-type>
        <jndi-name>java:jos</jndi-name>
    </resource-ref>
</jboss-web>

And the jos-ds.xml file that defines the data source is as follows: 

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE datasources
    PUBLIC "-//JBoss//DTD JBOSS JCA Config 5.0//EN"
    "http://www.jboss.org/j2ee/dtd/jboss-ds_5_0.dtd">

        <xa-datasource-property name="URL">${ie.courts.jos.datasource.url}</xa-datasource-property>

        <valid-connection-checker-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLValidConnectionChecker</valid-connection-checker-class-name>
        <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter</exception-sorter-class-name>
        <!--new-connection-sql></new-connection-sql-->
        <!--check-valid-connection-sql></check-valid-connection-sql-->
        <metadata>
            <type-mapping>mySQL</type-mapping>
        </metadata>
    </xa-datasource>
</datasources>

The stack trace that I get is:

That error is misleading, at least in my case, and the actual culprit being the XSD version. Change the XSD 5.1 to DTD 5.0 and it no more complain about the mapped-name .

Below is the WEB-INF/jboss-web.xml I m using now: (jboss-web.xml needs to be WEB-INF of your webapp) 

<?xml version="1.0"?>                                                                                                                             
<!DOCTYPE jboss-web PUBLIC
        "-//JBoss//DTD Web Application 5.0//EN"
        "http://www.jboss.org/j2ee/dtd/jboss-web_5_0.dtd">
<jboss-web>
<context-root>/context_name</context-root>
    <resource-ref>
        <res-ref-name>jdbc/jndi_name</res-ref-name>
        <res-type>javax.sql.DataSource</res-type>
        <jndi-name>java:jndi_name</jndi-name>
    </resource-ref>
</jboss-web>

Though this is some what old question, I m mentioning how I solved the same issue with JBoss 5.1.0 GA, so that someone may find it useful

您是否不使用这样的JNDI名称（在jboss-web.xml文件中）： 

<jndi-name>java:/jos</jndi-name>

Your jboss-web should look like: 

<jboss-web>
    <!-- ... -->
    <resource-ref>
        <res-ref-name>jdbc/jos</res-ref-name>
        <res-type>javax.sql.DataSource</res-type>
        <jndi-name>java:/jos</jndi-name>
    </resource-ref>
</jboss-web>
