Spring JNDI datasource not recognized after upgrade to ActiveMQ 5.6.0 - spring

I tested a ActiveMQ 5.5.0 (fuse version) app in AMQ 5.6.0 and noticed that our Spring JNDI configured Oracle datasources aren't being found.
The only thing I changed in my applications was the pom.xml versions of AMQ/Spring (to match the 5.6 versions). Otherwise, I'm using the identical application code and configuration (activemq.xml, jndi.xml, etc), but my Spring JDBC DAOs (v3.0.5) are failing to find them.
No errors in the logs otherwise, just this Spring Application Context initialization error...
javax.naming.NameNotFoundException; remaining name 'jdbc/myDataSource'
here is the relevant Spring jndi config (conf/jndi.xml, included in conf/activemq.xml)...
<bean id="jndi" class="org.apache.xbean.spring.jndi.SpringInitialContextFactory"
factory-method="makeInitialContext" scope="singleton">
<property name="entries" ref="jndiEntries" />
</bean>
<util:map id="jndiEntries">
<entry key="jdbc/myDataSource">
<bean id="myDBCPDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="oracle.jdbc.OracleDriver" />
...
then my application references it like this...
<bean id="myDataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName">
<value>jdbc/myDataSource</value>
</property>
</bean>
<bean id="messageDAO" class="com.mycompany.MessageDAOImpl">
<property name="dataSource" ref="myDataSource" />
</bean>
That said, I tested without using JNDI (instead just hardcoded the datasource in my app) and everything works as expected. So that should rule out everything except the Spring JNDI registration/lookup of the datasource, etc.
So, what am I missing?

ActiveMQ has a dependency into xbean-spring, which you are using as a JNDI provider. It is likely that the transitive Xbean dependency has changed because of the upgrade to ActiveMQ 5.6.0.

I found the issue, I added a jndi.properties file under the /conf directory containing the following and it works fine now (didn't need this under AMQ 5.5...strange)...
java.naming.factory.initial = org.apache.xbean.spring.jndi.SpringInitialContextFactory

Apache Camel Spring DSL, referring to an environment variable HOSTNAME

I am using Apache Camel 2.16.0 with Spring DSL
I have a Spring context XML in which I have defined a Property PlaceHolder to read the properties from various files as follows-
<bean id="propertyPlaceholder" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE"/>
<property name="ignoreResourceNotFound" value="false"/>
<property name="locations">
<list>
<value>classpath:/properties/versioning.properties</value>
<value>classpath:/properties/#{inetAddress.hostName}.properties</value>
</list>
</property>
</bean>
<bean id="inetAddress" class="java.net.InetAddress" factory-method="getLocalHost"/>
The property values are used to construct other beans such as -
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="org.gjt.mm.mysql.Driver"/>
<property name="url" value="${${LIVE_}DATASOURCE_URL}"/>
<property name="username" value="${${LIVE_}DATASOURCE_USERNAME}"/>
<property name="password" value="${${LIVE_}DATASOURCE_PASSWORD}"/>
</bean>
This works fine, I can see the beans being created.
I also have another Spring Context XML in the same app which has a camel context and I want to use the some other properties defined in the same properties files. I know that camel supports Spring Property Placeholder, see below excerpts from the context -
<camelContext id="charge-process-context" xmlns="http://camel.apache.org/schema/spring">
<propertyPlaceholder id="properties"
location="classpath:/properties/versioning.properties,
properties/${env:HOSTNAME}.properties"
xmlns="http://camel.apache.org/schema/spring" />
.....
.....
</camelContext>
As part of this context, I have a route that uses https component that uses the values from the property file such as below -
<to uri="https4:{{LIVE_AUTH_RESPONSE_HOST}}:{{LIVE_AUTH_RESPONSE_PORT}}/{{LIVE_AUTH_RESPONSE_CONTEXT_PATH}}"/>
This route does not start and throws following exception -

Please Note: I am deploying my application as a war file on Tomcat 8 on an AWS instance.
I have a Dev Environment on Windows 10 and I have found this working on the Windows OS. I have also seen that the file FilePathResolver.java in Apache Camel 2.16 uses System.getenv(key) to obtain the value i.e. System.getenv("HOSTNAME") which returns a null on AWS instance and a correct value on Windows 10. I also tried using env:hostname (small case letters for unix) but still no luck ...
I found a solution at http://camel.apache.org/using-propertyplaceholder.html
at Bridging Spring and Camel Property Placeholders
It mentions following -
The Spring Framework does not allow 3rd party frameworks such as Apache Camel to seamless hook into the Spring property placeholder mechanism. However you can easily bridge Spring and Camel by declaring a Spring bean with the type org.apache.camel.spring.spi.BridgePropertyPlaceholderConfigurer, which is a Spring org.springframework.beans.factory.config.PropertyPlaceholderConfigurer type.

Spring WorkManagerTaskExecutor cannot initialize in websphere

i want use Websphere work manager for executing async jobs in jee context but i have problem with creating spring WorkManager.
bean definition:
<bean id="taskExecutor" class="org.springframework.scheduling.commonj.WorkManagerTaskExecutor"> <property name="workManagerName" value="wm/default" /> </bean>
this definition i found in websphere help. But problem is this ends with noClassDefFound. I noticed pckg org.springframework.scheduling.commonj is missing from spring-context since version 2.x.x
Is it replaced with org.springframework.jca.work.WorkManagerTaskExecutor ?
when i use this other spring class, i get error:
Caused by: org.springframework.jndi.TypeMismatchNamingException:
Object of type [class com.ibm.ws.asynchbeans.WorkManagerImpl]
available at JNDI location [wm/default] is not assignable to
[javax.resource.spi.work.WorkManager]
so whats deal here? thx
was - 7.0.0.23
spring - 3.1.2
Class org.springframework.scheduling.commonj.WorkManagerTaskExecutor resides in spring-context-support-3.1.2.RELEASE.jar
Configuration succeeds with javax.resource.spi.work.WorkManager in applicationContext-service.xml in deployment.....
In my case deployment fails for bean injection org.springframework.scheduling.commonj.WorkManagerTaskExecutor as it fails to take WorkManager JNDI Configured in Application Server.... I just replaced javax.resource.spi.work.WorkManager. And so far it is success deployment.
I yet to see application works fine with it.
<bean id="taskExecutor" class="javax.resource.spi.work.WorkManager">
<property name="workManagerName" value="wm/default" />
</bean>
In our scenario we were managed it by ThreadPoolTaskExecutor instead of WorkManagerTaskExecutor
Here is configuration that comes in ApplicationContext.xml
<!--
<bean id="rtSenderTaskExecutor"
class="org.springframework.scheduling.commonj.WorkManagerTaskExecutor">
<property name="workManagerName">
<value>${org.quartz.threadPool.jndi}</value>
</property>
</bean> -->
<!-- Local Thread Pool -->
<bean id="rtSenderTaskExecutor"
class="org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor">
<property name="corePoolSize" value="${org.quartz.threadPool.corePoolSize}" />
<property name="maxPoolSize" value="${org.quartz.threadPool.maxPoolSize}" />
<property name="queueCapacity" value="${org.quartz.threadPool.queueCapacity}" />
<property name="keepAliveSeconds" value="${org.quartz.threadPool.keepAliveSeconds}"></property>
</bean>

Spring JTA transaction manager with Bitronix jndi lookup failures

I have a spring JTA transaction manager configured for Bitronix running on Tomcat 7. The transaction manager starts properly and the application works fine. I however get a lot of debug messages stating that
No JTA TransactionManager found at fallback JNDI location [java:comp/TransactionManager]
No JTA TransactionManager found at fallback JNDI location [java:pm/TransactionManager]
No JTA TransactionManager found at fallback JNDI location [java:appserver/TransactionManager]
etc..
I understand that this is the JtaTransactionManager scanning known jndi locations and this is not an error but a debug exception. The following is my transaction manager configuration
<bean id="BitronixTransactionManager" factory-method="getTransactionManager" class="bitronix.tm.TransactionManagerServices"
destroy-method="shutdown" />
and the jta transaction manager
<bean id="transactionManager" class="org.springframework.transaction.jta.JtaTransactionManager">
<property name="autodetectTransactionManager" value="false"/>
<property name="transactionManager" ref="BitronixTransactionManager" />
<property name="userTransaction" ref="BitronixTransactionManager" />
I thought that setting the autodetectTransactionManager value to false would prevent this scanning and the resulting debug exceptions but it seems this setting has no effect.
I also tried with the following properties for the transactionManager to set the jndi location.
<property name="transactionManagerName" value="java:comp/TransactionManager"/>
<property name="userTransactionName" value="java:comp/UserTransaction"/>
I am using jta 1.1 and also get the same lookup message for the TransactionSynchronizationRegistry:
DEBUG [main] JtaTransactionManager.findTransactionSynchronizationRegistry(146) | No JTA TransactionSynchronizationRegistry found at default JNDI location [java:comp/TransactionSynchronizationRegistry]
I would really like to understand this and not merely filter this out with my Log4J
Probably the problem is that in Tomcat the default jndi locations are in in java:comp/env. So you should do
<property name="transactionManagerName" value="java:comp/env/TransactionManager"/>
<property name="transactionSynchronizationRegistryName" value="java:comp/env/TransactionSynchronizationRegistry"/>
<property name="userTransactionName" value="java:comp/env/UserTransaction"/>

Weblogic Spring Dependency Injection from flat-files on the file-system

I have an application deployed into Oracle Weblogic 10.3. In my .ear files, I use spring injection from xml files in the ear files. I would like to also perform dependency injection from xml files placed on the server file-system. We do something similar to this in Karaf, where we place our configuration files for bundles in the conf directory in the server itself. Is there a similar way to do this in weblogic?
You can ask spring to read properties from file systems as below;
<!-- Reads application properties and uses them in the application context -->
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="ignoreResourceNotFound" value="true"/>
<property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE"/>
<property name="locations">
<list>
<value>file:D:\somefolder\application.properties</value>
<value>classpath:com/foo/sp.properties</value>
</list>
</property>
</bean>

Weblogic classpath and Spring Resources

I'm trying to set a bean property like this:
<bean id="threadImport" class="com.foo.bat.util.ThreadImport" singleton="false">
<property name="mailSender" ref="mailSender"/>
<property name="parseConfFile" value="classpath:parse/import.xml" />
<property name="logFilename" value="/tmp/import.log" />
but none of files are found. What's the classpath for my deployed application? May I set it on any weblogic xml descriptors? Which is the best way to place and locate files used on spring applications?
I am using:
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" value="classpath:foobar-config.properties" />
</bean>
The properties file is either location at the root of my test source folder so JUnit has a test-specific config available and in production, we have added a classpath entry to Weblogic pointing to the configuration folder. You can do that in the setDomainEnv.sh or for Managed Servers, in their configuration (web console), server start, classpath.
