I am Using Spring 2.5, Hibernate 3.2 and MySQL 5.1.32 (included in wamp 2.0)
applicationContext.xml
Code:
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="configLocation"
value="classpath:hibernate.cfg.xml">
</property>
</bean>
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory">
<ref bean="sessionFactory"/>
</property>
</bean>
<bean id="UsersDAO" class="com.smsapp.hibernate.UsersDAO">
<property name="sessionFactory">
<ref bean="sessionFactory" />
</property>
</bean>
<bean id="LocationDAO" class="com.smsapp.hibernate.LocationDAO">
<property name="sessionFactory">
<ref bean="sessionFactory" />
</property>
</bean>
Users.java, UsersDAO.java, Location.java and LocationDAO.java are generated with MyEclipse 7.0
I tried a simple delete with this code in LocationDAO.java
Code:
public static void main(String[] args) {
ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
LocationDAO loc = LocationDAO.getFromApplicationContext(ctx);
System.out.println(loc.findById(3).getLocationName());
loc.delete(loc.findById(3));
}
System.out.println returns the location name but I get this error:
Exception in thread "main" org.springframework.jdbc.UncategorizedSQLException: Hibernate operation: Could not execute JDBC batch update; uncategorized SQLException for SQL [delete from oms.location where id=?]; SQL state [41000]; error code [1205]; Lock wait timeout exceeded; try restarting transaction; nested exception is java.sql.BatchUpdateException: Lock wait timeout exceeded; try restarting transaction

Only save(), delete(), and update(), doesn't work. It's very annoying, everyone just keeps telling me to restart the transaction, but that doesn't seems to be the problem. Anyone experienced the same problem?
