HSQL org.hsqldb.HsqlException: invalid schema name

Question

I am using HSQL to run a number of unit tests on my java application. I am using Spring + Hibernate. I am having a problem when switching from MySQL to HSQL. The tests run perfectly on MySQL but whenever I change to HSQL I get the following exception:

Caused by: org.hsqldb.HsqlException: invalid schema name: LMS

My Spring configuration is the following:

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="org.hsqldb.jdbc.JDBCDriver" />
    <property name="url" value="jdbc:hsqldb:file:lms" />
    <property name="username" value="SA"/>
    <property name="password" value=""/>
</bean>


<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />

    <property name="packagesToScan">
        <list>
            <value>com.dreamteam.lms.**.*</value>
        </list>
    </property>

    <property name="hibernateProperties">
        <props>
            <!--<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>-->
            <prop key="hibernate.dialect">org.hibernate.dialect.HSQLDialect</prop>
            <prop key="hibernate.generate_statistics">true</prop>
            <prop key="hibernate.show_sql">false</prop>
            <prop key="hibernate.cache.use_second_level_cache">true</prop>
            <prop key="hibernate.cache.use_query_cache">true</prop>
            <prop key="hibernate.cache.provider_class">net.sf.ehcache.hibernate.SingletonEhCacheProvider</prop>
        </props>
    </property>
</bean>

Sample Annotation on one of my classes:

@Entity
@Table(name = "answer", catalog = "lms")
public class Answer implements Cloneable, Serializable, IPojoGenEntity, IAnswer {
.
.

Any insight would be appreciated.

make "create-schema.sql" file

CREATE SCHEMA lms;

add "dataSourceInitializer" bean

<bean id="dataSourceInitializer" class="org.springframework.jdbc.datasource.init.DataSourceInitializer">
    <property name="dataSource" ref="dataSource" />
    <property name="databasePopulator">
        <bean class="org.springframework.jdbc.datasource.init.ResourceDatabasePopulator">
            <property name="continueOnError" value="true" />
            <property name="scripts">
                <list>
                    <value>classpath:SQL/create-schema.sql</value>
                </list>
            </property>
        </bean>
    </property>
</bean> 

set "depends-on" attribute to "sessionFactory" bean

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean" depends-on="dataSourceInitializer">
