使用net.sourceforge.jtds.jdbc.Driver将SpringMVC与JDBC连接时出错

Question

I'm trying to do SpringMVC with JDBC Template.(SQL SERVER 2008 Database is used)

I inculded all jars needed to connect database.

Here is my DB connection bean coding

<!-- declare datasource bean -->
<bean id="dataSource"
    class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="net.sourceforge.jtds.jdbc.Driver" />
    <property name="url" value="jdbc:jtds:sqlserver://127.0.0.1:1098/userdb" />
    <property name="username" value="root" />
    <property name="password" value="root" />
</bean>

When i try to connect the Database, i got this error.

SEVERE: Servlet.service() for servlet [spring] in context with path [/SpringJDBCTemplate] threw exception [Request processing failed; nested exception is org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is java.sql.SQLException: Network error IOException: Connection refused: connect] with root cause

Answer 1

It looks like that your DB connection URL is not right or DB server is not available. Could you please verify that by logging using some client tool?
