Hello,

I am having applicationContext with one bean definition like below:
Code:
<beans>

	<bean id="test" name="test" class="com.jpmorgan.rubi.nukeeasy.service.Test"></bean>
	
</beans>


When I try to get bean using Eclipse RCP UI, though applicationContext.xml is getting loaded, I am getting "NoSuchBeanDefinitionException" when I try to get bean through this applicationContext.
Giving below the stack trace:
Code:
Mar 13, 2013 2:32:52 PM org.springframework.context.support.AbstractApplicationContext prepareRefresh

The RCP code to load applicationContext is written in its Activator.java as shown below:
Code:
// RCP start method
public void start(BundleContext context) throws Exception {
		super.start(context);
		plugin = this;

		if (appContext == null) {
			try {
				// appContext = new FileSystemXmlApplicationContext("classpath*:applicationContext.xml");
				appContext = new ClassPathXmlApplicationContext("classpath*:applicationContext.xml");

			} catch (Exception e) {
				e.printStackTrace();
			}
		}

	}



// Sample getter method
public ApplicationContext getApplicationContext() {
		return appContext;
	}


I have added required spring jar and commons-logging in RCP plug-in dependencies.

Now, when I click on submit button from RCP screen and try to get bean defined in applicationContext (like shown below), I am getting above mentioned error.

Code:
public void myBusinessMethodWhichGetsCalledOnClickOfRCPButton() {
		ApplicationContext appContext = Activator.getDefault().getApplicationContext();
                Test t = appContext.getBean("test"); /* getting NoSuchBeanDefinitionException here */
                .
                .
                .
                .
                .
                .
}

Then why am I getting above exception?

Any help would be extremely helpful.

P.S.: When I run and try to get bean using simple public static void main() method, I am getting it w/o any error.

Thanks,
AkshayL.
