JSP页面无法通过JBoss连接到MySQL数据源

我使用Eclipse来创建一个使用JSP页面的简单项目，该页面通过JBoss 6 AS从MySQL数据库中提取数据。看起来我已将MySQL数据库正确绑定到JBoss，因为它启动时没有错误，甚至显示以下消息。JSP页面无法通过JBoss连接到MySQL数据源

17:09:43,782 INFO [org.jboss.as.connector.subsystems.datasources] (MSC service thread 1-6) JBAS010400: Bound data source [java:jboss/datasources/MyDatabase]

然而，当我尝试推出我的index.jsp页面，我得到以下错误：

exception 


javax.servlet.ServletException: javax.servlet.jsp.JspException: Unable to get 
connection, DataSource invalid: "java.sql.SQLException: No suitable driver found for 
jdbc/MyDatabase"

org.apache.jasper.servlet.JspServlet.service(JspServlet.java:253) 
javax.servlet.http.HttpServlet.service(HttpServlet.java:847) 


root cause 

javax.servlet.jsp.JspException: Unable to get connection, DataSource invalid: "java.sql.SQLException: No suitable driver found for jdbc/MyDatabase" 
    org.apache.taglibs.standard.tag.common.sql.QueryTagSupport.getConnection(QueryTagSupport.java:318)

javax.servlet.http.HttpServlet.service(HttpServlet.java:847)

我似乎无法找出为什么这件事的最后一步，让我的JSP页面能够从数据库读取不起作用。

文件供参考：

的JBoss Standalone.xml

<subsystem xmlns="urn:jboss:domain:datasources:1.1"> 
     <datasources> 
      <datasource jndi-name="java:jboss/datasources/ExampleDS" pool-name="ExampleDS" enabled="true" use-java-context="true">

       <driver>h2</driver> 
       <security> 
        <user-name>sa</user-name> 
        <password>sa</password> 
       </security> 
      </datasource> 
      <datasource jta="true" jndi-name="java:jboss/datasources/MyDatabase" pool-name="MyDatabase" enabled="true" use-java-context="true">

       <driver>mysql</driver> 
       <security> 
        <user-name>root</user-name>

      </datasource> 
      <drivers> 
       <driver name="h2" module="com.h2database.h2"> 
        <xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class> 
       </driver> 
       <driver name="mysql" module="com.mysql"> 
        <driver-class>com.mysql.jdbc.Driver</driver-class> 
        <xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class> 
       </driver> 
      </drivers> 
     </datasources>

位于JBOSS_HOME /模块/ COM/MySQL的/主的Module.xml文件

<?xml version="1.0" encoding="UTF-8"?> 

<module xmlns="urn:jboss:module:1.1" name="com.mysql"> 
<resources> 
    <resource-root path="mysql-connector-java-5.1.25-bin.jar"/> 
</resources> 
<dependencies> 
    <module name="javax.api"/> 
    <module name="javax.transaction.api"/> 
    <module name="javax.servlet.api" optional="true"/> 
</dependencies> 
</module>

在JBOSS_HOME/modules/com/mysql/main里面我有mysql-connector-java-5.1.25-bin.jar

项

的web.xml内容

<display-name>TicketApp</display-name> 

<welcome-file-list> 
    <welcome-file>index.jsp</welcome-file> 
    <welcome-file>response.jsp</welcome-file> 
</welcome-file-list>

的jboss-web.xml中内容

Blank for now

还可以看出，当我在资源引用标签都该web插件。 xml和jboss-web.xml文件，一切都炸了，我从JBoss得到以下错误：

“<资源引用> JDBC/MyDatabase的 javax.sql.Datasource取得的java：JBoss的/数据源/ MYDATABASE ' 这是我试图添加到jboss-web.xml和web.xml中导致最后一个jboss错误的原因。 – thirdcoastx

ClassNotFoundException向我暗示JBOSS没有找到您的MySQL JDBC驱动程序类。

将JAR放入JBOSS服务器/ lib文件夹中，看看是否有帮助。

更新：这是在堆栈跟踪相关线路：

java.lang.ClassNotFoundException: javax.sql.Datasource

findjar.com说它应该是NI这些罐子之一。找到它。

我把MySQL连接器Jar放在lib文件夹中，我得到了相同的响应 – thirdcoastx
