java - 我如何在 JBoss AS 5.1.0.GA 中配置 JDBC 数据源？

Question

有人可以指出或发布为 JBoss 5.1.0.GA 配置数据源的示例吗？

当我尝试使用 JNDI 将数据源连接到我在 JBoss 5.1.0.GA 中的 Web 应用程序时出现以下错误。

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

我的 /WEB-INF/web.xml 包含以下资源引用:

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

我已经配置了 /META-INF/jboss-web.xml 如下:

<?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>

而定义数据源的jos-ds.xml文件如下:

<?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">${ie.courts.jos.datasource.url}</xa-datasource-property>
        <user-name>${ie.courts.jos.datasource.username}</user-name>
        <password>${ie.courts.jos.datasource.password}</password>

        <idle-timeout-minutes>2</idle-timeout-minutes>
        <track-connection-by-tx />
        <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>

我得到的堆栈跟踪是:

该错误具有误导性，至少对我而言是这样，真正的罪魁祸首是 XSD 版本。将 XSD 5.1 更改为 DTD 5.0，它不再提示 mapped-name。

下面是我现在使用的 WEB-INF/jboss-web.xml:(jboss-web.xml 需要是 WEB-INF你的网络应用)

<?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>

虽然这是个老问题，但我想提一下我是如何用 JBoss 5.1.0 GA 解决同样问题的，这样有人可能会觉得它有用
