based on your suggestion i updated my code
my
Code:
Manager.java
insertuser()
{
private static ApplicationContext springCtx;
if (springCtx == null) {
springCtx = (ApplicationContext) FacesContextUtils
.getRequiredWebApplicationContext(FacesContext
.getCurrentInstance());
}
return springCtx.getBean("Manager");
here our transcation will start
business.insertuser();
}
Code:
business.java we are using one method insertuser()
insertuser()
{
Tauser taUser=new Tauser();
taUser.setUsername("Maya");
taUser.setPassword("*****")
Dao.insertDetails(taUser);
throw new NullPointerException("checking transcation management"); // because of this exception throwing,it should rollback right,but its not happening.The property's are commiting in to the table.
}
and our dao.java class we are using one method insertuser(Object entity)
Code:
mport javax.persistence.EntityManager;
import org.hibernate.Criteria;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.ejb.HibernateEntityManager;
import org.springframework.orm.jpa.support.JpaDaoSupport;
import org.springframework.util.Assert;
public class dao extends JpaDaoSupport
{
void insertDetails(Object entity)
{
this.getJpaTemplate().persist(entity);
}
}
and our
Code:
orm.xml
<entity class="TaUser" name="TaUser">
<table name="ta_user" />
<attributes>
<id name="userId">
<column name="USER_ID" />
<generated-value strategy="AUTO" />
</id>
<basic name="userName">
<column name="USER_NAME" length="50" />
</basic>
</attributes>
</entity>
and my pojo class is
TaUser.java (here we are not using annotations so we mapping with orm.xml file )
Code:
public class TaUser implements java.io.Serializable
{
private int userId;
private String userName;
public int getUserId() {
return this.userId;
}
public void setUserId(int userId) {
this.userId = userId;
}
public String getUserName() {
return this.userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
}
and my persistence.xml file is
Code:
<persistence-unit name="webhub" transaction-type="JTA">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>java:comp/env/jdbc/shobWeb</jta-data-source>
<mapping-file>META-INF/orm.xml</mapping-file>
<class>TaUser</class>
---------
---------
---------
<properties>
<property name="hibernate.transaction.manager_lookup_class"
value="com.atomikos.icatch.jta.hibernate3.TransactionManagerLookup"/>
</properties>
</persistence-unit>
</persistence>
and i configured my jndi in
Code:
application/meta_inf/context.xml
<Resource name="jdbc/shobWeb" auth="Container"
driverClassName="com.mysql.jdbc.Driver"
user="root"
password="root"
type="com.mysql.jdbc.jdbc2.optional.MysqlXADataSource"
factory="com.mysql.jdbc.jdbc2.optional.MysqlDataSourceFactory"
url="jdbc:mysql://localhost:ebSample"
explicitUrl="true"
pinGlobalTxToPhysicalConnection="true"
></Resource>
and my config file i am configuring trancaction management
Code:
my config.xml is
<beans:bean id="Manager"
class="Manager">
<beans:property name="Business" ref="Business" />
</beans:bean>
<beans:bean id="Business" class="Business">
<beans:property name="Dao" ref="Dao" />
</beans:bean>
<beans:bean id="Dao"
class="Dao">
<beans:property name="jpaTemplate">
<beans:ref bean="jpaTemplate" />
</beans:property>
</beans:bean>
<beans:bean id="jpaTemplate" class="org.springframework.orm.jpa.JpaTemplate">
<beans:property name="entityManagerFactory">
<beans:ref bean="entityManagerFactory"/>
</beans:property>
</beans:bean>
<beans:bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<beans:property name="persistenceUnitName" value="webhub" />
<beans:property name="jpaVendorAdapter">
<beans:bean
class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<beans:property name="generateDdl" value="false" />
<beans:property name="showSql" value="true" />
<beans:property name="databasePlatform" value="org.hibernate.dialect.MySQLDialect" />
</beans:bean>
</beans:property>
<beans:property name="persistenceXmlLocation">
<beans:value>classpath:META-INF/persistence.xml</beans:value>
</beans:property>
<beans:property name="persistenceUnitManager">
<beans:ref bean="persistenceUnitManager"/>
</beans:property>
</beans:bean>
<beans:bean id="persistenceUnitManager" class="org.springframework.orm.jpa.persistenceunit.DefaultPersistenceUnitManager">
</beans:bean>
here i Configuread AOP Like this
<aop:config>
<aop:pointcut id="fooServiceOperation" expression="execution(* com.live.webAppl.*.*.*(..))"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="fooServiceOperation"/>
</aop:config>
<tx:advice id="txAdvice">
<tx:attributes>
<tx:method name="save*" rollback-for="UserExistsException"/>
<tx:method name="remove*"/>
<tx:method name="*" read-only="true"/>
</tx:attributes>
</tx:advice>
