Spring ApplicationContext with multiple context xml files from different projects in an application

I have two different projects in my application: data, web

I want to Auto wire a dao defined in my data in the web application layer.

So I created a master applicationContext.xml file in web and imported the entire Spring bean files like below

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://ift.tt/GArMu6"
    xmlns:xsi="http://ift.tt/ra1lAU"
    xsi:schemaLocation="http://ift.tt/GArMu6
    http://ift.tt/QEDs1e">

    <import resource="data/src/main/resources/spring/applicationContext-data.xml"/>
        <import resource="applicationContext.xml"/>

</beans>

@Configuration("file:**/Master-Module.xml")
public class MyService{
    @Autowired
    public  IMyDAO myDao;
    Practice practice1 = myDao.findById("3900");

The interface IMyDAO is defined in applicationContext-data.xml

When I deploy the application to Websphere and run it I get a NULL pointer exception.

Id is present in database.

It builds successfully in Maven when run as independent projects.

Below is the error I get:
