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

标签 java tomcat jdbc jndi jboss5.x

有人可以指点我或发布一个为 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 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>

我已配置/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>

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>

        <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:

最佳答案

该错误具有误导性，至少在我看来，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你的网络应用程序)

<?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">

虽然这是一些老问题，但我提到我如何使用 JBoss 5.1.0 GA 解决相同的问题，以便有人可能会发现它有用
