Spring resource - spring

Problem: I want to make the below bean definitions (specified in aaplicationContext.xml) optional for "org.springframework.web.context.ContextLoaderListener". If i am not providing the "emsPropLocation" context parameter correctly, tomcat web container is not able to initialized properly and it is obvious reason. Is there any way to make it optional?
appicationContext.xml:
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="ignoreResourceNotFound" value="false"/>
<property name="location" value="file:/#{contextParameters.emsPropLocation}" />
</bean>
<!-- TIBCO Connection Factory Bean -->

<property name="userPassword" value="${emsPassword}"/>
<property name="connAttemptCount" value="${connAttemptCount}"/>
<property name="connAttemptDelay" value="${connAttemptDelay}"/>
<property name="connAttemptTimeout" value="${connAttemptTimeout}"/>

<property name="exceptionListener" ref="jmsExceptionListener"/>
</bean>

</bean>
We are keeping WAR file outside tomcat and to make it happen we have "app.xml" file inside TOMCAT_HOME/conf/Catalina/localhost.
app.xml:
<Context path="/app"
docBase="/abc/ccp/app.war"
reloadable="true"
unpackWAR="false">
<Parameter name="emsPropLocation"
value="/xyz/config/EMSServerConf.properties"
override="false"/>
</Context>

have a try to change the ignoreResourceNotFound property of your propertyConfigurer to true.

If contextParameters.emsPropLocation is not set, this will default to what is afer the colon.
<property name="location" value="file:/#{contextParameters.emsPropLocation:/xyz/config/EMSServerConf.properties}" />

By default, ApplicationContext implementations eagerly create and
configure all singleton beans as part of the initialization process.
Generally, this pre-instantiation is desirable, because errors in the
configuration or surrounding environment are discovered immediately,
as opposed to hours or even days later. When this behavior is not
desirable, you can prevent pre-instantiation of a singleton bean by
marking the bean definition as lazy-initialized. A lazy-initialized
bean tells the IoC container to create a bean instance when it is
first requested, rather than at startup.
Can you please try to lazily initialize your bean using below construct.
lazy-init="true"
<bean id="messageTopic1" class="org.apache.activemq.command.ActiveMQTopic"
lazy-init="true">
<constructor-arg value="${amq.topic}" />

If anyone has worked on apache camel using XA transactions can you guys provide me your sample config file so that i can use and modify it.
This works for me. It looks like you've missed the ActiveMQResourceManager. Also ensure you use a XAPooledConnectionFactory otherwise your MDBs will disconnect after every bind to check for a message (and CPU on the broker will go through the roof).

Prevent ResourcePropertySource from throwing FileNotFoundException

Is there a way to prevent ResourcePropertySource from throwing java.io.FileNotFoundException
<bean class="org.springframework.context.support.PropertySourcesPlaceholderConfigurer">
<property name="ignoreResourceNotFound" value="true" />
<property name="ignoreUnresolvablePlaceholders" value="true" />
<property name="propertySources">
<list>
<bean class="org.springframework.core.io.support.ResourcePropertySource">
<constructor-arg value="file:#{systemProperties['user.home']}/user.properties"/>
</bean>
<bean class="org.springframework.core.io.support.ResourcePropertySource">
<constructor-arg value="classpath:project.properties"/>
</bean>
</list>
</property>
</bean>
I'd like t to fallback to the project.properties if the user.properties file if not found
Why so complex.
<context:property-placeholder location="${user.home}/user.properties,classpath:project.properties" ignore-resource-not-found="true" />
That should be all you need. No need for EL or directly use a ResourcePropertySource.

JNDI access with Tomcat 7 and embedded HornetQ

I set up a new project with Tomcat 7.0 and an embedded HornetQ JMS server.
I used these 2 tutorials to help me:
http://www.javacodegeeks.com/2010/06/spring-3-hornetq-21-integration.html
http://wash-inside-out.blogspot.com/2010/08/hornetq-jms-integration-with-tomcat.html
But as it is mentioned in the tutos, the Tomcat JNDI repository is readonly (cannot find a way to write) and I configured a "separated" JNDI used by HornetQ, the messaging works, but Tomcat cannot access it.
Normally, in my other projects using Tomcat, I defined the datasource as a global resource in the server.xml and I map it in the context.xml. doing this, the definition of the datasource (jdbc url, credentials, etc...) are outside the application and can be managed by environment (dev, test, prod, ...) but I cannot find a way to do it with the other JNDI.
Currently, the datasource is defined in my application with an external property file for the parameters but I am not really satisfied with this solution.
Here is my Spring configuration:
<!-- enable autowire -->
<context:annotation-config />
<!-- enable transaction demarcation with annotations -->
<tx:annotation-driven transaction-manager="transactionManager" />
<bean id="dataSource" class="org.apache.tomcat.jdbc.pool.DataSource">
<property name="driverClassName" value="com.informix.jdbc.IfxDriver" />
<property name="url" value="${URL}" />
<property name="username" value="${user}" />
<property name="password" value="${password}" />
<property name="maxActive" value="50" />
<property name="maxIdle" value="10" />
<property name="maxWait" value="1000" />
<property name="removeAbandoned" value="true" />
<property name="removeAbandonedTimeout" value="300" />
<property name="logAbandoned" value="true" />
</bean>
<!-- HornetQ config -->

How can I managed it in a better way, I mean, define the datasource on the server side as usual? Is there a configuration to tell Tomcat to use the external JNDI I defined or create a read/write repo?
