Hello everyone. I'm a newbie in Spring. I am Using Spring 2.5, Hibernate 3.2 and MySQL 5.1.32 (included in wamp 2.0)
This is my allpicationContext.xml
Users.java, UsersDAO.java, Location.java and LocationDAO.java... etc. are generated with MyEclipse 7.0 Hibernate Reverse-Engineering ToolsCode:<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>
I tried a simple delete with this code in LocationDAO.java
System.out.println returns the location name but I get this error: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)); }
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?
