Question

I am trying to run a springexample. I have configured my .xml file as follows. I am using mysql as my DB, but I’m getting the error mentioned below

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

    <bean id="dataSource" destroy-method="close" 
        class="org.apache.commons.dbcp.BasicDataSource">
        <property name="driverClassName" value="org.hsqldb.jdbcDriver"/>
        <property name="url" value="jdbc:hsqldb:hsql://127.0.0.1:3306"/>
        <property name="username" value="root"/>
        <property name="password" value="root"/>
    </bean>

    <bean id="forumDAO" class="com.vaannila.dao.ForumDAOImpl">
         <property name="dataSource" ref="dataSource"/>
    </bean>
</beans>

error

EDIT

now changed to

<property name="driverClassName" value="com.mysql.jdbc.Driver"/>
<property name="url" value="jdbc:mysql://127.0.0.1:3306/test"/>
<property name="username" value="root"/>
<property name="password" value="root"/>

Exception in thread “main”

Answer 1

Your configuration file is setup for a HSQL database instead of a MySQL database.
Use:

<property name="driverClassName" value="com.mysql.jdbc.Driver"/>
<property name="url" value="jdbc:mysql://localhost/DATABASE_NAME"/>

You should also check, that you have the correct JDBC driver in your classpath.
