Spring is not able to load bean from a jar file

Question

I have a jar which defines a bean like:

@Component(value="SHTTP")
public class SHTTPImpl{
}   

Inside the jar , i have another class which loads the above defined bean like:

public static xx getInstance() {
   getApplicationContext().getBean("SHTTP"); //Exception thrown here
}

where the function getApplicationContext() is defined as:

private static AnnotationConfigApplicationContext getApplicationContext() {
    if (appContext == null) {
        appContext = new AnnotationConfigApplicationContext(XXContext.class);
    }
    return appContext;
}

Now, I added this jar file inside another project ,say "project B" which has its own xml application context. I have a class inside project B which tries to get the bean "SHTTPImpl" by calling function

getInstance()

.

But, this doesnt seem to work as i get the org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'SHTTP' is defined

This problem occurs only when i run my testcase. IF i deploy my application in the server and run, the bean not found exception isnt happening. But, writing working testcase is important for me. So, please help me out

Thanks

EDIT : Here is my test case

@Test
public void testprocessRequestMessageType() throws Exception{
    ProcessIncomingTransactionsNoThreads processIncomingTransactionNoThreads = (ProcessIncomingTransactionsNoThreads)getBean("processTransactions");
    processIncomingTransactionNoThreads.processRequestMessageType(cm); //This method tries to load the bean from the jar file
}

public class BaseTest extends TestCase {
public static ApplicationContext getContext() {
    return new FileSystemXmlApplicationContext("/src/test/resources/test-service-context.xml");
}

public static Object getBean(String beanName) {
    return getContext().getBean(beanName);
}   
}

EDIT 2: I think it would be better to add how i define the root of my context in the jar file. Here is the content of

XXContext.java file:

  @Configuration
  @ComponentScan(basePackages = { "com.xxx.adapter.sms" }) //SHTTPImpl is in package com.xxx.adapter.sms.syn
  public class XXContext {
    @Bean
    ...
   }

The file test-service-context.xml in the project (this is not inside jar) defines a bunch of beans that isnt related to the issue in hand

EDIT 3 Adding test-service-context.xml content (only relevant parts)
