I am doing a very simple test and this is not working for me. I am using spring and hibernate facets, my DB is only a single table but I cannot reverse engineer it. I get the following error in the log

!ENTRY org.eclipse.core.jobs 4 2 2014-05-16 13:56:21.690

I am using the latest mysql driver – mysql-connector-java-5.1.30-bin
I am able to connect to the database fine using the DB explorer.

Below is my simple schema as well as my db conection info that I configure via spring

CREATE TABLE `system_settings` (
    `id` INTEGER NOT NULL,
    `name` VARCHAR(40) NOT NULL,
    `value` VARCHAR(40) NOT NULL,
    `comments` VARCHAR(40),
    CONSTRAINT `PK_system_settings` PRIMARY KEY (`id`)
)
ENGINE=INNODB;

<bean id="mainDataSource" 
        class="org.apache.commons.dbcp.BasicDataSource"
        destroy-method="close">

        <property name="driverClassName"><value>com.mysql.jdbc.Driver</value></property>
        <property name="url"><value>jdbc:mysql://localhost/apc</value></property>
        <property name="username"><value>apc</value></property>
        <property name="password"><value>apc</value></property>
        <property name="defaultAutoCommit"><value>false</value></property>

        <property name="maxActive"><value>50</value></property>

    </bean>

    <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="dataSource">
            <ref bean="mainDataSource" />
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQLInnoDBDialect</prop>
                <prop key="hibernate.show_sql">false</prop>
                <prop key="hibernate.jdbc.batch_size">50</prop>
            </props>
        </property>
        <property name="mappingLocations">
            <list>
                <value>/mappings/*.hbm.xml</value>
            </list>
        </property>
    </bean>

Though I have noticed that it doesn’t matter what I put in my spring config, i get the same error. I tried putting bad connection info to see if that changed the error but it didn’t. So it seems to ignore what is in that file. When i reverse engineer I select my spring file for generated DAO files.

Hi, I ended up deleting the project and starting over and that fixed it somehow.
