i have the following declared in spring.xml:
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
...
</bean>
<bean id="sessionFactory"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="configLocation" value="classpath:hibernate.cfg.xml" />
</bean>
<bean id="transactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
<!-- Adapters -->
<bean id="ADBAdapter" class="model.adapter.ADBAdapter">
<constructor-arg>
<ref bean="sessionFactory" />
</constructor-arg>
</bean>
So after i created the context. I can Access my ADBAdapter and do stuff.
The Problem is, that i want to use ADBAdapter in another Thread.
But then i get sometimes a SessionClosed Exception, because the session gets closed in the parent thread.
How can I handle this ?
Thank you for your help
In hibernate you can use
hibernate.current_session_context_class=thread

When I using JndiObjectFactoryBean as dataSource in applicationContext.xml, it seems that sqlSessionFactory's property could not refer to this dataSource...What should I do to solve it?
enter image description here
My codes are show below:

I'm using Camel-Mybatis version 2.12.0.redhat-610379, when we trying to start the bundle thru karaf container the following exception throws. Please advice.

Connections and configurations are created properly, the bug I have made was in bean.xml i have used myBatis bean id, and camel route i have type as mybatis, due to case-sensitive, no environment was created, sorry for that.

Now I have existing form based login UI. I want to use same instead of using jasig web login screen. I found this link "Using CAS from external link or custom external form" using which I can use my login UI. Can anybody help me to integrate same with spring security in my application ?
After you integrate your application.you can change and edit casviewpage.jsp.You can change all UI.You use default casview.jsp and edit it.Why dont want to edit casview.jsp?
I am having an issue creating xa datasources in spring 4.0.
I have setup my datasources in weblogic using an xa driver.
I then added added jndi-lookups for the data sources in spring:
<jee:jndi-lookup id="dataSourceOne" jndi-name="/jdbc/XAONE" resource-ref="true" />
<jee:jndi-lookup id="dataSourceTwo" jndi-name="/jdbc/XATWO" resource-ref="true" />
I have then created the configuration for the entity managers:
<bean id="emfone" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSourceOne" />
<property name="jpaVendorAdapter" ref="jpaVendorAdapter" />
<property name="packagesToScan" value="..." />
</bean>
<bean id="emftwo"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSourceTwo" />
<property name="jpaVendorAdapter" ref="jpaVendorAdapter" />
<property name="packagesToScan" value="..." />
</bean>
<bean id="jpaVendorAdapter"
class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="database" value="ORACLE" />
<property name="showSql" value="true" />
<property name="generateDdl" value="false" />
<property name="databasePlatform" value="org.hibernate.dialect.Oracle10gDialect" />
</bean>
After this I have my transaction manager configured:
<tx:annotation-driven />
<tx:jta-transaction-manager />
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="emfone" />
<qualifier value="tmOne"/>
</bean>
<bean id="docTransactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="emftwo" />
<qualifier value="tmTwo"/>
</bean>
I have a service class method annotated with #Transactional that calls a DAO. The DAO uses both entity managers for persisting data.
When the DAO tries to persist using the emftwo a no transaction in progress error is thrown. Does anybody know where I am going wrong?
Thanks,
My question is somewhat related to this; Can I use multiple C3P0 datasources for DB instance?
I have two Spring web services which accesses the same mySQL database schema. And I am using c3p0 to pool database connections. I am accessing the database using JPA/Hibernate
I have configured two data base pools, entitity manager factories and transaction managers similar to the above question.
In the first service
<bean id="dataSource1" class="com.mchange.v2.c3p0.ComboPooledDataSource"
destroy-method="close" p:driverClass="com.mysql.jdbc.Driver" p:jdbcUrl="jdbc:mysql://localhost/test?zeroDateTimeBehavior=convertToNull"
p:user="test1" p:password="test1"
p:acquireIncrement="1" p:idleConnectionTestPeriod="10" p:maxPoolSize="25"
p:maxStatements="20" p:minPoolSize="5" >
</bean>
<bean id="entityManagerFactory1"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="persistenceXmlLocation" value="classpath*:META-INF/persistence.xml"></property>
<property name="persistenceUnitName" value="hibernatePersistenceUnit1" />
<property name="dataSource" ref="dataSource1" />
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="showSql" value="true" />
</bean>
</property>
</bean>
<bean id="transactionManager1" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="dataSource" ref="dataSource1" />
<property name="entityManagerFactory" ref="entityManagerFactory1" />
</bean>
In the second service
<bean id="dataSource2" class="com.mchange.v2.c3p0.ComboPooledDataSource"
destroy-method="close" p:driverClass="com.mysql.jdbc.Driver" p:jdbcUrl="jdbc:mysql://localhost/test?zeroDateTimeBehavior=convertToNull"
p:user="test1" p:password="test1"
p:acquireIncrement="1" p:idleConnectionTestPeriod="10" p:maxPoolSize="25"
p:maxStatements="20" p:minPoolSize="5" >
</bean>
<bean id="entityManagerFactory2"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="persistenceXmlLocation" value="classpath*:META-INF/persistence.xml"></property>
<property name="persistenceUnitName" value="hibernatePersistenceUnit2" />
<property name="dataSource" ref="dataSource2" />
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="showSql" value="true" />
</bean>
</property>
</bean>
<bean id="transactionManager2" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="dataSource" ref="dataSource2" />
<property name="entityManagerFactory" ref="entityManagerFactory2" />
</bean>
Also I have annotated the two data access classes with relevant transaction manager
#Transactional("transactionManager1")
public class JPADataAccessObject1<T, ID extends Serializable> implements DataAccessObject<T, ID>
#Transactional("transactionManager2")
public class JPADataAccessObject2<T, ID extends Serializable> implements DataAccessObject<T, ID>
One of my services has a spring message channel which uses a jpa-inbound-channel-adapter
<int:channel id="testChannel">
<int:priority-queue capacity="20" />
</int:channel>
<int-jpa:inbound-channel-adapter
channel="testChannel" entity-class="com.test.TestObject"
entity-manager-factory="entityManagerFactory1" auto-startup="true"
jpa-query="SELECT x FROM TestObject AS x WHERE x.testColumns LIKE '1'"
delete-after-poll="true">
<int:poller fixed-rate="5000">
<int:transactional propagation="REQUIRED"
transaction-manager="transactionManager1" />
</int:poller>
</int-jpa:inbound-channel-adapter>
Now the problem is when I deploy both services in tomcat 7 they become not responding. Any idea on this?
I went on a different approach and setup a container managed database pool in tomcat and referred as a JNDI resource.
In Server.xml
<Resource type="javax.sql.DataSource"
name="jdbc/TEST"
factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost/test?zeroDateTimeBehavior=convertToNull"
username="test1"
password="test1"
initialSize="10"
maxActive="100"
maxIdle="50"
minIdle="10"/>
In Context.xml
<ResourceLink type="javax.sql.DataSource"
name="jdbc/LocalTEST"
global="jdbc/TEST"/>
And the bean configuration for the datasource is,
<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="java:comp/env/jdbc/LocalTEST"/>
</bean>
