Spring + Hibernate + Maven: jCannot create JDBC driver of class 'com.mysql.jdbc.Driver' for connect URL 'jdbc:mysql//localhost:3306/test'

Question

I have my mysql-connector jar in:

1.) Tomcat Server lib

2.) Build Path as an External JAR. * Removed from Maven dependency, although it remains with the same error.

jdbc.properties

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.dialect=org.hibernate.dialect.MySQLDialect
jdbc.databaseurl=jdbc:mysql//localhost:3306/test
jdbc.username=root
jdbc.password=****

web.xml adding it with a snippet:

<resource-ref>
    <description>DB Connection</description>
    <res-ref-name>jdbc/test</res-ref-name>
    <res-type>javax.sql.DataSource</res-type>
    <res-auth>Container</res-auth>
</resource-ref>

And my complete servlet-context.xml

<context:annotation-config />
<context:component-scan base-package="org.springsecudev.controller" />
<context:component-scan base-package="org.springsecudev.model" />
<context:component-scan base-package="org.springsecudev.service" />
<context:component-scan base-package="org.springsecudev.dao" />

        </beans:props>

        <beans:property name="cacheSeconds" value="0"/>
        <beans:property name="useExpiresHeader" value="true"/>
        <beans:property name="useCacheControlHeader" value="true"/>
        <beans:property name="useCacheControlNoStore" value="true"/>
    </beans:bean>
</interceptors>

<beans:bean id="encoder"  
class="org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder">
    <beans:constructor-arg value="12"></beans:constructor-arg>
</beans:bean>

I also added the context.xml in META-INF to be sure I tried this one as well with

<Context>
<WatchedResource>WEB-INF/web.xml</WatchedResource>
<Resource  name="jdbc/test" 
        username="root" 
        password="root" 
        driverClassName="com.mysql.jdbc.Driver"
        url="jdbc:mysql://localhost:3306/test"
        auth="Container" 
        type="javax.sql.DataSource"
        maxActive="100" 
        maxIdle="30" 
        maxWait="10000"
        initialSize="1"/>

But still no luck, it also has the same error being:

I've been trying to find out what could be the problem wherein I have copied the jar in build path and server lib.

Answer 1

seems like you're missing the colon in file jdbc.properties for the database URL.

jdbc:mysql//localhost:3306/test

I think it should be

jdbc:mysql://localhost:3306/test
