SMX and multiple spring contexts
I have multiple Spring contexts used for maintaining my service mechanisms
and would like to know how to incorporate them into the SMX-mix of things.
For example, I have a JBI unit that unmarshals xml data into POJOs. This
flow is all defined in my servicemix.xml. Now in my unmarshaller, I would
like to invoke a service that will process these populated POJOs. The
service definitions are defined in a separate appContext.xml file. So how
can I inject my services into the unmarshaller which is managed by SMX?
servicemix.xml:
--------------------
......
<sm:activationSpec componentName="pojoUnmarshaller"
service="foo:pojoUnmarshaller">
<sm:component>
<bean class="com.test.servicemix.integration.TestPojoUnmarshaller">
</bean>
</sm:component>
</sm:activationSpec>
.....
--------------------
TestPojoUnmarshaller.java
------------------------------
...
private ProcessPojoService service;
public void setProcessPojoService( ProcessPojoService service) {
this.service = service;
}
public void process(MessageExchange exchange, NormalizedMessage message) {
.... // do some unmarshalling
Pojo data = (Pojo)unmarshaller.unmarshal(inputstream);
service.processPojo(data);
...
}
---------------------------
appContext.xml
----------------------------
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-2.0.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-2.0.xsd">
<bean id="pojoService" class="com.test.service.PojoServiceImpl"/>
.....
----------------------------------
Now how do I combine everything above so that I can inject my PojoService
into the Unmarshaller (which is managed by SMX) using an external Spring
configuration file (not part of servicemix.xml)? Thanks in advance.

The context files in ServiceMix are processed by the XBean-Spring
module (http://geronimo.apache.org/xbean) which is built on top of
Spring and it does support a classpath element.

The imported contexts are pure Spring contexts and there is no such thing as
a <classpath> element-- here's the dtd:

Re: SMX and multiple spring contexts
Posted by Guillaume Nodet <gn...@gmail.com>.
AFAIK, the classpath should be preprocessed first, but it may not be
set correctly when the imported context is loaded.
Have you tried putting the classpath tag in the imported context ?

Re: SMX and multiple spring contexts
Posted by moraleslos <mo...@hotmail.com>.
I'm running into dependency issues when doing this. Seems like the <import
resource...> imports the Spring contexts and tries to load the beans up
first before continuing with the jbi-based dependencies. Basically in my
Spring context contains a bean for a service POJO which utilizes Hibernate.
I have the Hibernate jar defined in servicemix.xml like this:
<import resource=classpath:appContext.xml/>
<classpath>
<location>lib/hibernate-3.2.1.ga.jar</location>
...
</classpath>
However, seems like it tries to find Hibernate dependencies needed
implicitly by my appContext.xml before ever reaching the classpath
dependencies. I had to explicitly put the hibernate jar into SMX's
/lib/optional directory to make everything nice and neat. Is there a way to
make it work w/o putting the jar into SMX's lib/optional directory?

Re: SMX and multiple spring contexts
Posted by Guillaume Nodet <gn...@gmail.com>.
Take a look at the main servicemix.xml in the distribution.
It uses <import> tags to load other spring configuration files.
Like this one:
<import resource="classpath:security.xml" />

Re: SMX and multiple spring contexts
Posted by moraleslos <mo...@hotmail.com>.
Well, I'm not sure if I want to convert my pure Spring 2.0 context files into
xbean-spring files which requires another dependency (xbean-spring.jar)
since if I choose to have these app contexts run outside of smx, I don't
really have to change a thing. Maybe this is a bug with xbean? I was
thinking that the <classpath>s would be looked upon first before anything
else happens (i.e. before processing <import resource...). Is there another
way around this?
