<p>I'm an end-user of one of my company's products. It is not very suitable for integration into Spring, however I am able to get a handle on the context and retrieve the required bean by name.  However, I would still like to know if it was possible to inject a bean into this class, even though the class is not managed by Spring itself.</p>

<p>Clarification: The same application which is managing the lifecycle of some class MyClass, is also managing the lifecycle of the Spring context. Spring does not have any knowledge of the instance of MyClass, and I would like to some how provide the instance to the context, but cannot create the instance in the context itself.</p>

suppose that u have the following dependency chain:
A --> B --> C --> x --> y -- > Z
A, B, C are spring managed beans (constructed and manged  by spring framework)
x, y are really simple POJOs that constructed by your application, without spring assistance
now if you want that y will get a reference to Z using spring that you need to have a 'handle' to the spring ApplicationContext
one way to do it is to implement
ApplicationContextAware
interface . In this case I would suggest that either A, B or C will implement this interface and will store the applicationContext reference in a static member.
so lets take Class C for example:
```
```
class C implmenets ApplicationContextAware{
    public static ApplicationContex ac;
     void setApplicationContext(ApplicationContext applicationContext)  {
               ac = applicationContext;
     }
 .............
}
```
```
now, in class y you should have:
```
```
(Z)(C.ac.getBean("classZ")).doSomething()
```
```
