I try to configure springdata with embedded-database. Context file inspired from http://cooldevstuff.wordpress.com/2012/09/20/in-memory-database-using-spring-3-2/
My context file:
<jdbc:embedded-database id="embeddedDataSource">
<jdbc:script location="classpath:schemaFile.sql" />
<jdbc:script location="classpath:dataFile.sql" />
</jdbc:embedded-database>
<jpa:repositories base-package="aa.bb.repository" />
<bean class="org.springframework.orm.hibernate4.HibernateExceptionTranslator" />
<bean id="entityManagerFactory">
<property name="dataSource" ref="embeddedDataSource" />
<property name="persistenceUnitName" value="SamplePU"></property>
</bean>
but I get error:
No unique bean of type [javax.persistence.EntityManagerFactory] is defined: expected single bean but found 0.
what I missed?
The configuration is just invalid. Your bean entityManagerFactory does not declare any class attribute.

I have a Spring Integration WAR component that I'm updating to run in private PCF. I have two DataSources and a RabbitMQ connection factory defined in the application.
I see an article from Thomas Risberg on using the cloud namespace and handling multiple services of the same time - https://spring.io/blog/2011/11/09/using-cloud-foundry-services-with-spring-part-3-the-cloud-namespace. This is handled by using #Autowired and #Qualifier annotations.
I'm wondering how this can be achieved though when we're not #Autowired and #Qualifier annotations, e.g. wiring a DataSource into a JdbcTemplate. Here we do not have the ability to specify a #Qualifier annotation.
My application is Spring XML config based. I do have ability to use #Autowired and #Qualifier annotations on one of the DataSources, but the other is JPA entity manager. See code snippet.
Any help is much appreciated.

Output from CF when I deploy https://gist.github.com/anonymous/3986a1a7cea4f20c096e. Note it is skipping auto re-configuration of javax.sql.DataSources
First of all, the post from Thomas is pretty old, and references a deprecated support library. Instead of the org.cloudfoundry:cloudfoundry-runtime:0.8.1 dependency, you should use Spring Cloud Connectors dependencies instead.
You can then follow the instructions provided for using XML configuration with Spring Cloud Connectors. With multiple services of the same type, you will need to specify the name of the service for each bean. Following your example, and assuming you created two CF database services named inventory-db and customer-db, that might look something like this:
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="inventory-dataSource" />
<property name="persistenceUnitName" value="activity-monitor" />
<property name="jpaVendorAdapter" ref="jpaVendorAdapter"/>
<property name="jpaProperties">
<value>
hibernate.format_sql=true
</value>
</property>
</bean>
<beans profile="cloud">
<cloud:data-source id="inventory-dataSource" service-name="inventory-db">
<cloud:data-source id="customer-dataSource" service-name="customer-db">
</beans>
I've managed to resolve the issue by using the factory bean used by the spring cloud:data-source, CloudDataSourceFactory. Creating an instance of this and wiring up the config including the service-name of the CF service. This avoids the issue of our PropertySourcesPlaceholderConfigurer trying to use the data source before our the bean has even been defined.
<!--
configure cloud data source for using CloudDataSourceFactory; this is what spring cloud:data-source is using;
required to manually wire this data source bean as cloud:data-source bean gets defined in a phase after our
PropertySourcesPlaceholderConfigurer bean.
-->
<bean id="cic.properties.dataSource" class="org.springframework.cloud.service.relational.CloudDataSourceFactory">
<constructor-arg value="oracle-cicadm-db-service" />
<constructor-arg>
<!-- configuring minimal data source as it is used only to bootstrap properties on app start-up -->
<bean class="org.springframework.cloud.service.relational.DataSourceConfig">
<constructor-arg>
<bean class="org.springframework.cloud.service.PooledServiceConnectorConfig.PoolConfig">
<constructor-arg value="0" />
<constructor-arg value="2" />
<constructor-arg value="180" />

i build async jersey web services, and now i need to make some operations with ldap.
I have configure Spring beam.xml in this mode:
<bean id="contextSourceTarget" class="org.springframework.ldap.core.support.LdapContextSource">
<property name="url" value="${ldap.url}" />
<property name="base" value="${ldap.base}" />
<property name="userDn" value="${ldap.userDn}" />
<property name="password" value="${ldap.password}" />
<property name="pooled" value="false" />
</bean>
<bean id="contextSource"
class="org.springframework.ldap.pool.factory.PoolingContextSource">
<property name="contextSource" ref="contextSourceTarget" />
</bean>
<bean id="ldapTemplate" class="org.springframework.ldap.core.LdapTemplate">
<constructor-arg ref="contextSource" />
</bean>
<bean id="ldapTreeBuilder" class="com.me.ldap.LdapTreeBuilder">
<constructor-arg ref="ldapTemplate" />
</bean>
<bean id="personDao" class="com.me.ldap.PersonDaoImpl">
<property name="ldapTemplate" ref="ldapTemplate" />
</bean>
But when i try to use ldap i have this error:
Error creating bean with name 'contextSource' defined in class path resource [config/Beans.xml]: Instantiation of bean failed; nested exception is java.lang.NoClassDefFoundError: org/apache/commons/pool/KeyedPoolableObjectFactory
In my project i have commons-pool2-2.2.jar lib, but still i have this error..i try to add commons-pool2-2.2.jar in TOMCAT_PATH/lib but not works..
UPDATE:
If i put commons-pool-1.6.jar it works.. but if i want to use pool2 how i can do? only i must change class inn commons-pool2-2.2.jar?
Updated Answer:
Since at least Spring LDAP 2.3.2 you can now use commons-pool2. Spring LDAP now provides two classes:
For commons-pool 1.x:
org.springframework.ldap.pool.factory.PoolingContextSource
For commons-pool 2.x:
org.springframework.ldap.pool2.factory.PooledContextSource
Details can be found here:
https://github.com/spring-projects/spring-ldap/issues/351#issuecomment-586551591
Original Answer:
Unfortunately Spring-Ldap uses commons-pool and not commons-pool2. As you have found the class org.apache.commons.pool.KeyedPoolableObjectFactory does not exist in commons-pool2 (it has a different package structure), hence the error.
There is a Jira issue for the Spring-ldap project asking them to upgrade/support commons-pool2:
https://jira.spring.io/browse/LDAP-316
Until that has been completed you will have to use commons-pool 1.6.
I am trying to integrate spring with mybatis.I have done all the configuartions.
I have following versions :
Spring : 3.0.6
Mybatis : 3.0.6
mybatis-spring : 1.0.2
When I use above combination of jars ,at the startup of tomcat,it throws exception that SqlSessionFactoryBean classNotFound and when I actually check mybatis-spring-1.0.2 jar ,SqlSessionFactoryBean is actually not there.
Then I switched to mybatis-spring-1.2.0
Now on using this jar ,on server startup ,I get following error message :
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlSessionFactory' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.mybatis.spring.SqlSessionFactoryBean]: Constructor threw exception; nested exception is java.lang.NoClassDefFoundError: org/apache/ibatis/mapping/VendorDatabaseIdProvider

</bean>
<bean id="transactionDao" class="com.abc.daoImpl.TransactionDaoImpl">
<property name="sqlSessionFactory" ref="sqlSessionFactory" />

Can you please let me know,what is probelm here .
Thanks in advance.
This class belongs to Ibatis and not MyBatis. Make sure that you have Ibatis as either direct dependency or transitive dependency.
I set it this way:
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="typeAliasesPackage" value="mx.com.dctechnology.model"/>
<property name="mapperLocations" value="classpath*:mx/com/dctechnology/dao/maps/*.xml" />
</bean>
<bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
<constructor-arg index="0" ref="sqlSessionFactory" />
</bean>
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="mx.com.dctechnology.dao" />
</bean>

I was trying to share My in-memory jobRepository to the jobExplorer. But it throws an error as,
Nested exception is
org.springframework.beans.ConversionNotSupportedException:
Failed to convert property value of type '$Proxy1 implementing
org.springframework.batch.core.repository.JobRepository,org.
springframework.aop.SpringProxy,org.springframework.aop.framework.Advised'
to required type
Even i tried putting '&' sign before jobRepository when passing to jobExplorer for sharing.But attempt end in vain.
I am using Spring Batch 2.2.1
Is the dependency for jobExplorer is only database not in-memory?
Definition is,
<bean id="jobRepository"
class="com.test.repository.BatchRepositoryFactoryBean">
<property name="cache" ref="cache" />
<property name="transactionManager" ref="transactionManager" />
</bean>
<bean id="jobOperator" class="test.batch.LauncherTest.TestBatchOperator">
<property name="jobExplorer" ref="jobExplorer" />
<property name="jobRepository" ref="jobRepository" />
<property name="jobRegistry" ref="jobRegistry" />
<property name="jobLauncher" ref="jobLauncher" />
</bean>
<bean id="jobExplorer" class="test.batch.LauncherTest.TestBatchExplorerFactoryBean">
<property name="repositoryFactory" ref="&jobRepository" />
</bean>
<bean id="transactionManager"
class="org.springframework.batch.support.transaction.ResourcelessTransactionManager" />
<bean id="jobLauncher" class="com.scb.smartbatch.core.BatchLauncher">

</bean>
<!-- To store Batch details -->

<bean id="jobRegistryBeanPostProcessor"

<property name="jobRegistry" ref="jobRegistry" />
</bean>
<!--Runtime cache of batch executions -->
<bean id="cache" class="com.scb.cache.TCRuntimeCache" />
thanks for your valuable inputs.
But I used '&' before the job repository reference, which allowed me to use it for my job explorer as a shared resource.
problem solved.
kudos.
Usually you have to wire interface instead of implementation.
Else, probably, you have to add <aop:config proxy-target-class="true"> to create CGLIB-based proxy instead of standard Java-based proxy.
Read Spring official documentation about that

The source of this error is the following line:
<property name="dataSource" ref="springbatch.batchDataSource"/>
Which means that you need a bean definition with id "springbatch.batchDataSource" configured as a data source for your environment which seems to not exist. You may use the following as a template; do not forget to provide your database driver and connection information.
<bean id="springbatch.batchDataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName" value="org.hsqldb.jdbcDriver" />
<property name="url" value="jdbc:hsqldb:mem:testdb" />
<property name="username" value="sa" />
<property name="password" value="" />
