Error deploying Hibernate app on JBoss - No suitable driver found for jdbc

I have a Spring/Hibernate web application (currently working fine on Tomcat) that I am attempting to deploy to JBoss 7.1 AS.

The application all starts correctly, but if I set the Hibernate Persistence settings to create tables then I get an error on startup.

My persistence XML that was working on tomcat is as follows:

<persistence-unit name="persistenceUnit"
    transaction-type="RESOURCE_LOCAL">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <properties>
        <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" />
        <property name="hibernate.hbm2ddl.auto" value="create" />
        <property name="hibernate.ejb.naming_strategy" value="org.hibernate.cfg.ImprovedNamingStrategy" />
        <property name="hibernate.show_sql" value="false" />
    </properties>
</persistence-unit>

When I moved this PU to JBoss I started getting errors stating that it couldnt connect to the DB:

20:41:18,312 ERROR [org.hibernate.tool.hbm2ddl.SchemaExport] (MSC service thread 1-5) HHH000231: Schema export unsuccessful: java.lang.UnsupportedOperationException: The application must supply JDBC connections

I googled and found a suggestion that I update my PU as follows by adding the hibernate connection details in the persistence config:

<persistence-unit name="persistenceUnit"
    transaction-type="RESOURCE_LOCAL">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <properties>
        <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" />
        <property name="hibernate.hbm2ddl.auto" value="create" />
        <property name="hibernate.ejb.naming_strategy" value="org.hibernate.cfg.ImprovedNamingStrategy" />
        <property name="hibernate.show_sql" value="false" />
        <property name="hibernate.connection.url" value="jdbc\:mysql\://localhost\:3306/socialcv" />
        <property name="hibernate.connection.username" value="root" />
        <property name="hibernate.connection.password" value="root" />
        <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver" />
    </properties>
</persistence-unit>

I have done this, and no longer get the user errors, but now just get the following error on app startup:

20:35:41,791 ERROR [org.hibernate.tool.hbm2ddl.SchemaExport] (MSC service thread 1-8) HHH000231: Schema export unsuccessful: java.sql.SQLException: No suitable driver found for jdbc\:mysql\://localhost\:3306/socialcv

Has anyone come across this or know any solution?

First of all: your DB connection URL looks incorrect. It should probably be jdbc:mysql://localhost:3306/socialcv.

Then:

Best install the MySQL driver as a module, see here: https://community.jboss.org/wiki/DataSourceConfigurationinAS7#Installing_a_JDBC_driver_as_a_module

Then use standalone.xml to define a data source using that driver:

            <datasource jta="true" jndi-name="java:jboss/datasources/YourDatasourceName" pool-name="AnotherName" enabled="true" use-java-context="true" use-ccm="true">
                <connection-url>jdbc:mysql://localhost:3306/socialcv</connection-url>
                <driver>mysql</driver>
                <transaction-isolation>TRANSACTION_READ_COMMITTED</transaction-isolation>
                <pool>
                    <min-pool-size>10</min-pool-size>
                    <max-pool-size>100</max-pool-size>
                    <prefill>true</prefill>
                    <use-strict-min>false</use-strict-min>
                    <flush-strategy>FailingConnectionOnly</flush-strategy>
                </pool>
                <security>
                    <user-name>hehe</user-name>
                    <password>hehehe</password>
                </security>
            </datasource>
            <drivers>
                ...
                <driver name="mysql" module="com.mysql">
                    <xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class>
                </driver>
            </drivers>

In your persistence.xml don't use the hibernate.connection.* properties, instead use:

<non-jta-data-source>java:jboss/datasources/YourDatasourceName</non-jta-data-source>

This is the de facto way to init the whole thing. Note, when using

transaction-type="JTA"

instead of

transaction-type="RESOURCE_LOCAL"

you have to change to

<jta-data-source>java:jboss/datasources/YourDatasourceName</jta-data-source>

which gives you CMT (container-managed transactions).
