please advise why i get this error, and how to fix it, thanks.
Try using the org.springframework.orm.hibernate4.HibernateTransactionManager
<bean id="transactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="dataSource" ref="dataSource" />
<property name="sessionFactory" ref="sessionFactory" />

My Requirement is I need to have two datasource connected to Spring Batch Application.
1) One for Spring Batch Jobs and Executions storing
2) One for Business Data Stroing, Processing and Retreiving.
I know that there are lot of solutions for achieving this. But I have achieved by setting the second datasource as primary. The problem is the second datasource is not coming under transaction scope instead it is committing for each sql statement executing expecially through jdbctemplate.
As I can't able to edit my question. I am writing another Post in detail

I have the custom Batch configurer set. Now the problem is when I try to execute queries with jdbctemplate for update and insert it is not under transaction which means #Transactional is not working.
Rather commit is happening for each method call. The example is
#Transactional
public void checkInsertion() throws Exception{
try{
jdbcTemplate.update("INSERT INTO TABLE_NAME(COLUMN1, COLUMN2) VALUES( 'A','AF' );
throw new PddaException("custom error");
}catch(Exception ex){
int count=jdbcTemplate.update("ROLLBACK");
log.info("DATA HAS BEEN ROLLBACKED SUCCESSFULLY... "+count);
throw ex;
}
}
In the above code I am trying to insert data and immediately I am also throwing a exception which means the insert should happen but commit will not. So we will not be able to see any data but unfortunately the commit is happening. Please some one help

I am developing a web application and I need two DataSource to connect two difference database according to my requirement.One DataSource will use Spring + JPA framework and another DataSource is use Spring + MyBatis framework.
Yes you can I suggest manage both from spring and obtained from the applicationContext.
<bean class="org.apache.tomcat.jdbc.pool.DataSource" id="dataSource" >
<property name="driverClassName" value="${database.driverClassName}"/>
<property name="url" value="${database.url}"/>
<property name="username" value="${database.username}"/>
<property name="password" value="${database.password}"/>
<bean class="org.apache.tomcat.jdbc.pool.DataSource" id="dataSourceOrderDetail" >
<property name="driverClassName" value="${database.driverClassName}"/>
<property name="url" value="${database.url.orderdetail}"/>
<property name="username" value="${database.username}"/>
<property name="password" value="${database.password}"/>
</bean>
Just need to have different name of id, to be properly injected
Check this to review how you can integrate spring with ibatis then configure beans using the datasource beans
Or if you want to use datasource-ds.xml just put the two datasource xml files in the lib folder within your application context, if you are using something like jboss or tomcat.

You can configure as many databases as you like in Spring context by declaring datasource beans with different id's and
injecting appropriate properties from properties file. if the two databases are different then you are in territory of distributed transactions and you must configure a Spring transaction manager which can operate with JTA. Also worth noting is that Spring transaction manager is merely an abstraction and it needs to have external JTA transaction
manager configured (like Bitrionix / Atomikos) or if deploying under EE application server then transaction manager can be looked up in JNDI registry. Then when you mark the transaction boundary (perhaps using Spring Transactional annotation) then Spring would automatically co-ordinate the transactions.
I want to dynamically change Datasource properties in Spring+MyBatis project.
Problem is in Spring + MyBatis integration, we cannot set the datasource properties dynamically during runtime.
Currently I'm using the following code to set the credentials:
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close" p:driverClassName="${jdbc.driverClassName}"
p:url="${jdbc.url}" p:username="${jdbc.username}"
p:password="${jdbc.password}" />
I tried options with UserCredentialsDataSourceAdapter to change the password during runtime but I cannot return back the dataSource object to use for the connection as MyBatis
ApplicationContext context = ApplicationContextUtils.getApplicationContext();
UserCredentialsDataSourceAdapter ds = (UserCredentialsDataSourceAdapter) context.getBean("dataSource");
ds.setCredentialsForCurrentThread("test", "test");
I'm stuck here, I cannot use the dataSource element ds to use for making connection for MyBatis. Please help me in resolving this issue.
I suppose that you use mybatis-spring.
Your approach with UserCredentialsDataSourceAdapter is not working because you are using connection pool, so connection is not closed after usage but are returned to the pool and reused later even that you've changed username and password.
To fix this just get rid of pool:
<bean id="targetDataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${jdbc.driverClassName}"/>
<property name="url" value="${jdbc.url}"/>
</bean>
<bean id="dataSource" class="org.springframework.jdbc.datasource.UserCredentialsDataSourceAdapter">
<property name="targetDataSource" ref="targetDataSource"/>
<property name="username" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
</bean>
and use the later bean in SqlSessionFactoryBean configuration:
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
</bean>
If you do not use mybatis-spring and use mybatis directly then the problem is to make mybatis use configured DataSource. This can be done by registering dataSource in JNDI and configure mybatis to get DataSource from JNDI.
<bean id="targetDataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${app.jdbc.driverClassName}" />
<property name="url" value="${app.jdbc.url}" />
</bean>
<bean id="dataSource"
class="org.springframework.jdbc.datasource.UserCredentialsDataSourceAdapter">
<property name="targetDataSource" ref="targetDataSource" />
<property name="username" value="#{app.jdbc.username}" />
<property name="password" value="#{app.jdbc.password}" />
</bean>

I using Mule Studio version: 1.3.1 .
buildDate: 201209061215
I am not able to get JPA end point. I also downloaded jpa-connector-1.0-20120925-2201.jar
But I dont know to to integrate with mule studio.
So I decided to use a simple Java transformer and write my processing logic which will be internally using JPA/Hibernate.
I came to know that i have to use a JPA vendor adapter for spring, else none of my service, DAO classes will be instantiated.
I have declared a datasource and entityManager as beans of spring inside mule flow xml as shown.
<spring:bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<spring:property name="driverClassName" value="com.mysql.jdbc.Driver" />
<spring:property name="url" value="jdbc:mysql://localhost:3306/eigDB" />
<spring:property name="username" value="root" />
<spring:property name="password" value="tiger" />
</spring:bean>
<spring:bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<spring:property name="dataSource" ref="dataSource" />
<spring:property name="persistenceUnitName" value="autoRebateSystem" />
<spring:property name="jpaVendorAdapter">
<spring:bean
class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<spring:property name="databasePlatform" value="org.hibernate.dialect.Oracle10gDialect" />
<spring:property name="showSql" value="true" />
</spring:bean>
But mule flow xml is not able to recognize any class of spring framework.
Finding very difficult to replace those class names.
Plez provide the solution for my problem,
By letting me know the PROPER replacements for mule studio.
1) org.springframework.jdbc.datasource.DriverManagerDataSource
2) org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean
3) org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter
Are you missing to use HibernateJpaDialect and JpaTransactionManager;
I hope the following configuration will be useful.
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver"/>
<property name="url" value="jdbc:mysql://localhost:3306/yourdatabase"/>
<property name="username" value="your- username"/>
<property name="password" value="your- password"/>
</bean>
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory"/>
</bean>
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<!--<property name="dataSource" ref="dataSource"/>-->
<property name="persistenceUnitName" value="<your-persistunit-name>"/>
<property name="jpaVendorAdapter" ref="jpaVendorAdapter"/>
<property name="jpaDialect">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaDialect/>
</property>
<property name="loadTimeWeaver">
<bean class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver">
</bean>
</property>
</bean>
<bean id="jpaVendorAdapter" class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="databasePlatform" value="org.eclipse.persistence.platform.database.MySQLPlatform"/>
<!-- <property name="databasePlatform" value="org.eclipse.persistence.platform.database.OraclePlatform" />-->
<property name="generateDdl" value="false"/>
<property name="showSql" value="false"/>
</bean>
To integrate it within MuleStudio, please add this update site within MuleStudio:
