How to move location of Atomikos's tm.out and *.epoch files? - spring

I'm running a J2SE application that uses Atomikos which dumps it's numerous log files to the current directory. I'd like to move the location of these files to "/tmp", but I cannot locate a configuration property that I can set from within my Spring XML config file.
The Atomikos documentation references a property:
com.atomikos.icatch.output_dir
Which seems exactly what I need, but how to set from Spring it without a jta.properties file? Here is my transaction manager config:
<bean id="transactionManager" class="org.springframework.transaction.jta.JtaTransactionManager">
<property name="transactionManager" ref="atomikosTransactionManager" />
<property name="userTransaction" ref="atomikosUserTransaction" />
</bean>
<bean id="atomikosTransactionManager" class="com.atomikos.icatch.jta.UserTransactionManager"
init-method="init" destroy-method="close">
<!-- When close is called, should we force transactions to terminate? -->
<property name="forceShutdown" value="false" />
</bean>
<bean id="atomikosUserTransaction" class="com.atomikos.icatch.jta.UserTransactionImp">
<!-- Number of seconds before transaction timesout. -->
<property name="transactionTimeout" value="30" />
</bean>

The property in question must be set on the singleton instance of the transactionService -- an object that is normally created on-demand by the user transaction manager:
<bean id="userTransactionService" class="com.atomikos.icatch.config.UserTransactionServiceImp"
init-method="init" destroy-method="shutdownForce">
<constructor-arg>
<!-- IMPORTANT: specify all Atomikos properties here -->
<props>
<prop key="com.atomikos.icatch.service">com.atomikos.icatch.standalone.UserTransactionServiceFactory</prop>
<prop key="com.atomikos.icatch.output_dir">target/</prop>
<prop key="com.atomikos.icatch.log_base_dir">target/</prop>
</props>
</constructor-arg>
</bean>
Now the property is set. But in order to ensure you don't have two transaction services running you must also modify the user transaction manager bean as follows:
<bean id="atomikosTransactionManager" class="com.atomikos.icatch.jta.UserTransactionManager"
init-method="init" destroy-method="close" depends-on="userTransactionService">
<!-- When close is called, should we force transactions to terminate? -->
<property name="forceShutdown" value="false" />
<!-- Do not create a transaction service as we have specified the bean in this file -->
<property name="startupTransactionService" value="false" />
</bean>

spring bean optional property

I am using a data source defined in tomcat in my spring configuration as shown in the below xml.
It can happen sometimes that this data source may not be defined in the context.xml of tomcat.
In such cases , the context initialization fails since myDS is not found.
Is it possible to configure the datasource as optional so that application initialisation is not impacted ?
There can be a run time error when this data source is accessed , which is acceptable
<bean id="myDataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="java:comp/env/jdbc/myDS"/>
</bean>
<bean id="myEntityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="myDataSource" />
<property name="persistenceXmlLocation" value="classpath:META-INF/persistence.xml" />
<property name="packagesToScan" value="com..XX.XX" />
<property name="persistenceUnitName" value="myPU" />
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="showSql" value="#{systemProperties['showSql'] == null ? 'true' : systemProperties['showSql'] }" />
</bean>
</property>
<property name="persistenceUnitPostProcessors">
<list>
<ref bean="wrkflw-punitpostprocessor" />
</list>
</property>
<property name="jpaProperties">
<props>
<prop key="hibernate.dialect">#{systemProperties['dbDialect']}</prop>
</props>
</property>
</bean>
Thanks

You may check the DelegatingDataSource, you could encapsulate the logic to load the datasource from JNDI within its instantiation. For your application there will be always a DataSource there, but in some cases (whenever its not able to load the DataSource from JNDI) there is no delegation.

Spring: JMSTemplate/CachingConnectionFactory deployables unable to start automatically in weblogic

I recently changed some of my application to use the the following:
org.springframework.jndi.JndiTemplate
org.springframework.jms.connection.CachingConnectionFactory
org.springframework.jms.core.JmsTemplate
Everything is working fine and I'm able to deploy my war files and send JMS messages to the queue.
However something peculiar happens when my managed server restarts. The deployables will all go into a fail state which requires me to then manually start them up.
This started happening after the change to use caching connection factory, jndi template and jms template.
My SpringConfig file:
<!-- Service Controller begin -->
<bean id="appUtils" class="com.foo.util.AppUtil" lazy-init="true" />
<bean id="jms_jndiTemplate" class="org.springframework.jndi.JndiTemplate" lazy-init="true">

<props>
<prop key="java.naming.factory.initial">#{jmsJndiFactory}</prop>
<prop key="java.naming.provider.url">#{jmsIp}</prop>
</props>
</property>
</bean>
<bean id="jmsUtils" class="com.foo.JmsUtil" >

<bean id="jmsFactory" class="java.lang.String" ><constructor-arg value="${jmsFactory.local}" /></bean>
<bean id="jmsJndiFactory" class="java.lang.String" ><constructor-arg value="${jmsJndiFactory.local}" /></bean>
<bean id="jmsIp" class="java.lang.String" ><constructor-arg value="${jmsIp.local}" /></bean>
applicationProperties file:
jmsQueue.local=jms/Queue
jmsFactory.local=jms/ConnectionFactory
jmsJndiFactory.local=weblogic.jndi.WLInitialContextFactory
jmsIp.local=t3://localhost:7031
Anyone has any idea as to why this might be happening? I'm using Weblogic. Any help would be greatly appreciated.
Thanks!
Edit: Forgot to mention that the error causing the failed state is
javax.naming.NameNotFoundException: Unable to resolve 'jms.Queue'. Resolved 'jms'; remaining name 'Queue'.
This is a JNDI error. The message means "I tried to find jms/Queue in the JNDI context but I only got as far as jms; there is no Queue child below".
Check the resources which you configured for the application in WebSphere.

spring jndi values from JNDI tree

I am working with spring 3.0 and within our JBoss application server I perform a JNDI lookup to a remote WebLogic application server. The properties to connect to the WebLogic JNDI server are contained in a properties file called soa.properties. Here is what the spring-config.xml looks like to initialize the JndiTemplate bean
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath:app.properties</value>
<value>classpath:soa.properties</value>
</list>
</property>
</bean>
<bean id="soaJndiTemplate" class="org.springframework.jndi.JndiTemplate">
<property name="environment">
<props>
<prop key="java.naming.factory.initial">${soa.provider.initial}</prop>
<prop key="java.naming.provider.url">${soa.provider.url}</prop>
<prop key="java.naming.security.principal">${soa.security.principal}</prop>
<prop key="java.naming.security.credentials">${soa.security.credentials}</prop>
</props>
</property>
</bean>
This works fine for pulling my values out of the soa.properties file, but what I would rather do is pull the WebLogic JNDI connection values out of the JBoss JNDI tree.
My problem appears to be with the initialization of the InitialContext object that requires Properties for initialization.
I put all of my JNDI String values for WebLogic JNDI connection into the JBoss JNDI. Below is the code I am using to pull the values out and initialize JndiTemplate bean.
<bean id="soaUrl" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="soa/provider/url" />
</bean>
<bean id="soaFactory" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="soa/provider/connection/factory" />
</bean>
<bean id="soaInitial" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="soa/provider/initial" />
</bean>
<bean id="soaPrincipal" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="soa/security/principal" />
</bean>
<bean id="soaCredential" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="soa/security/credential" />
</bean>
<bean id="testsoaJndiTemplate" class="org.springframework.jndi.JndiTemplate">
<property name="environment">
<map>
<entry key="java.naming.factory.initial" value-ref="soaUrl" />
<entry key="java.naming.provider.url" value-ref="soaFactory" />
<entry key="java.naming.provider.initial" value-ref="soaInitial" />
<entry key="java.security.principal" value-ref="soaPrincipal" />
<entry key="java.security.credential" value-ref="soaCredential" />
</map>
</property>
</bean>
My application comes up with these beans created, but when I use testsoaJndiTemplate with say soaConnectionFactory like so it boms.
<bean id="soaConnectionFactory" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiTemplate" ref="testsoaJndiTemplate" />
<property name="jndiName" value="${soa.provider.connection.factory.name}" />
</bean>
The error is so cryptic it does make any sense.
Thanks

EJB 3.0 -> Spring -> JPA (JTA as transaction manager)

I am currently working on a project that includes EJB 3.0 (stateless SB), JPA (Hibernate as the provider), JTA as transaction manager. The app server is JBoss AS 7. Spring is used for integrating EJB and JPA.
All seems to be working fine, except if there is any exception that occurs in the EJB, then the persistence unit is closed by Spring. On the subsequent request, the persistence unit is again created, which becomes time consuming and also should not happen in the ideal situation.
Below are the configuration details
persistence.xml
<persistence-unit name="test" transaction-type="RESOURCE_LOCAL">
<class>com.test.User</class>
<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" />

The class JtaPersistenceUnitPostProcessor is responsible for setting the transaction-type as JTA and the datasource to jta-datasource.
Could anyone please provide any help on this.
Thanks in advance.
<bean id="transactionManager"
class="org.springframework.transaction.jta.JtaTransactionManager">

<tx:annotation-driven transaction-manager="transactionManager" />
<bean class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor" />
you didn't specify any error message . you can add these lines in your configuration file .
I see you use JTA transaction manager and use that only if you use distributed Transaction and use JNDI. JTA tran. manager listens TX happening through connection acquired from JNDI datasource. If you have datasource created in your code and is not a part of Web container but is limited inside app. container in your web server, JTA wont work.
If you want to implement Tx manager with in a single app. context go for JPA transaction manager which is very reliable.

Spring/JTA/JPA DAO integration test doesn't rollback?

My DAO integration tests are failing because entities created during the tests are still in the database at the start of the next test. The exact same behavior is seen from both MySQL 5 and H2.
The test classes are annotated with:
#Transactional
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration( { "/testPersist-applicationContext.xml" })
The transaction bean configuration in the test application context is as follows:
<tx:annotation-driven />
<bean id="transactionManager"
class="org.springframework.transaction.jta.JtaTransactionManager">
<property name="transactionManager" ref="atomikosTransactionManager" />
<property name="userTransaction" ref="atomikosUserTransaction" />
</bean>
<bean id="atomikosTransactionManager" class="com.atomikos.icatch.jta.UserTransactionManager"
init-method="init" destroy-method="close">
<property name="forceShutdown" value="false" />
</bean>
<bean id="atomikosUserTransaction" class="com.atomikos.icatch.jta.UserTransactionImp">
<property name="transactionTimeout" value="300" />
</bean>
The entity manager is configured as follows:
<bean id="myappTestLocalEmf"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="persistenceUnitName" value="myapp" />
<property name="persistenceUnitPostProcessors">
<bean class="com.myapp.core.persist.util.JtaPersistenceUnitPostProcessor">
<property name="jtaDataSource" ref="myappPersistTestJdbcDataSource" />
</bean>
</property>
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="showSql" value="false" />
<property name="database" value="$DS{hibernate.database}" />
<property name="databasePlatform" value="$DS{hibernate.dialect}" />
</bean>
</property>
<property name="jpaProperties">
<props>
<prop key="hibernate.transaction.manager_lookup_class">com.atomikos.icatch.jta.hibernate3.TransactionManagerLookup
</prop>
<prop key="hibernate.format_sql">true"</prop>
<prop key="hibernate.use_sql_comments">true</prop>
</props>
</property>
</bean>
<context:annotation-config />
Everything in the log files seem to be fine...I can see messages from Spring about rollback and from Atomikos about rollback as well. But frankly, the logs are so huge and so complex, I could easily be missing something...
Yet the inserted test data remains! Any clues?
It turned out that my C3P0 JDBC data source was not XA aware and was therefore not participating in the transaction. Why I did not get an error, nor a warning in the log file, I do not know. Nonetheless, the reason you cannot use an XA aware data source is explained very nicely here. Note that the data source does not need to be XA capable...just XA aware.
Replacing the C3P0 data source with the following one solved the problem.
<bean id="myappJTANonXADataSource" class="com.atomikos.jdbc.nonxa.AtomikosNonXADataSourceBean">
<property name="uniqueResourceName" value="myappDatabase" />
<property name="driverClassName" value="$DS{hibernate.connection.driver_class}" />
<property name="url" value="$DS{hibernate.connection.url}" />
<property name="user" value="$DS{hibernate.connection.username}" />
<property name="password" value="$DS{hibernate.connection.password}" />
<property name="maxPoolSize" value="20" />
<property name="reapTimeout" value="300" />
</bean>
I think you will need to go through the logs in details. It could be that the rollbacks you are seeing are working, except that something else has executed a commit first. I also cannot see anything in your code which indicates automated rollback. And that it should occur at the end of each test. If you are depending on a timeout based rollback it could be that the second test is running before the timeout occurs, therefore it sees the data before it is rolled back.
Many options here there is :-)
