Tomcat 7 - mysql driver cannot be found

Question

I want to setup MySql as a data source for Tomcat so it can be used with Spring. I have defined the data source in Tomcat's context.xml and added MySQl connector jar to Tomcat's libs

ls /opt/tomcat/tomcat/lib/ | grep mysql
mysql-connector-java-5.1.35-bin.jar

Here is $TOMCAT/conf/context.xml :

<Context>

    <WatchedResource>WEB-INF/web.xml</WatchedResource>

 <Resource name="jdbc/mysqldb"
     auth="Container"
     type="javax.sql.DataSource"
     username="my-user"
     password="my-password"
     driverClassName="com.mysql.jdbc.Driver"
     url="jdbc:mysql:/localhost:3306/organizer"
     maxActive="8"
     maxIdle="4"/>

</Context>

and here is the relevant part of springContext.xml although I doubt it matters in this case.

<jee:jndi-lookup id="dataSource" jndi-name="/jdbc/mysqldb"
    resource-ref="true" />

But still I get this exception:

What am I missing?

Answer 1

Changes your $TOMCAT/conf/context.xml: to

<Context>

<WatchedResource>WEB-INF/web.xml</WatchedResource>

<Resource name="jdbc/mysqldb"
   auth="Container"
   type="javax.sql.DataSource"
   username="my-user"
   password="my-password"
   driverClassName="com.mysql.jdbc.Driver"
   url="jdbc:mysql://localhost:3306/organizer"
   maxActive="8"
   maxIdle="4"/>

</Context>

You have missed to add "/" in url.
