Table not found error in h2 using hibernate3

Question

I am newbie to h2 database.i created the sessionfactory like below.

<bean id="dataSource"
        class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="org.h2.Driver" />
        <property name="url" value="jdbc:h2:~/selva;DB_CLOSE_DELAY=-1" />
        <property name="username" value="" />
        <property name="password" value="" />
    </bean>

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

        <property name="annotatedClasses">
        <list>
            <value>com.selva.meetinghall.domain.My</value>  
            </list>
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">${hibernate.dialect}</prop>
                <prop key="hibernate.show_sql">${hibernate.show_sql}</prop>




            </props>
        </property>
    </bean>

My.java

@Entity
@Table(name="my")
@Repository
public class My implements java.io.Serializable {
    private static final long serialVersionUID = -1798070786993154670L;
     @Id
     @Column(name ="Id")
     private int id;
     @Column(name ="Name")
     private String name;
    //getter and setter
}

Dao :

Session session=sessionfactory.openSession();
    Transaction tx=session.beginTransaction();
    My my=new My();
    my.setId(1);
    my.setName("selva");
    session.save(my);
    tx.commit();

I got the error like below.

Hibernate: insert into my (Name, Id) values (?, ?)
2015-01-20 18:41:02,911 WARN  org.hibernate.util.JDBCExceptionReporter.logExceptions:77 - SQL Error: 42102, SQLState: 42S02
2015-01-20 18:41:02,911 ERROR org.hibernate.util.JDBCExceptionReporter.logExceptions:78 - Table "MY" not found; SQL statement:

org.hibernate.exception.SQLGrammarException: could not insert: [com.selva.meetinghall.domain.My]

The above code works for mssql persistent database.But does not work in h2 database.What's wrong with my approach? Is Querying is different for inmemory and persistent databse? Any help will be greatly appreciated!!
