Cannot read Spring bean from ServiceMix

[josh3006]

Hi,

I would like to read my spring.xml from a jar file which I deployed in Servicemix.
Activiti Engine is also running on the same Servicemix. Currently, I'm unable to read Spring bean.

Please find the xml below which located in META-INF

root
–META-INF
—-Spring.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:osgi="http://www.springframework.org/schema/osgi"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="
            http://www.springframework.org/schema/beans
            http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
            http://www.springframework.org/schema/osgi
            http://www.springframework.org/schema/osgi/spring-osgi.xsd">

    <bean id="helloWorldService" class="com.bw.osgi.provider.impl.HelloWorldServiceImpl"/>

    <osgi:service ref="helloWorldService" interface="com.bw.osgi.provider.able.HelloWorldService"/>
</beans>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I'm trying to use Expression to read this bean

${helloWorldService}‍

Do you have an exception?

I'm no expert in osgi, but this sounds more like an osgi problem than an Activiti one?

Please find the error stacks as below :-

It say "Unknown property used in expression" when I use the expression.

Yes. you are right, this looks like issue with Servicemix.
I had to add my bean in applicationContext.xml in activiti-explorer

eg : \apache-tomcat-6.0.35\webapps\activiti-explorer\WEB-INF\applicationContext.xml

But I was wondering, why we need to define our bean in here ?
I already define my bean inside my jar file.. Why activiti did not find the bean

[jbarrez]

The explorer app indeed boots its engine using that spring config file, it doesn't use the ProcessEngines class. That's the reason why it doesn't pick up the engine config.
