| <p> |
| This is an object factory that produces a jndi naming |
| context based on a classloader. |
| <p> |
| It is used for the <code>java:comp</code> context. |
| <p> |
| This object factory is bound at <code>java:comp</code>. When a |
| lookup arrives for java:comp, this object factory |
| is invoked and will return a context specific to |
| the caller's environment (so producing the <code>java:comp/env</code> |
| specific to a webapp). |
| <p> |
| The context selected is based on classloaders. First |
| we try looking at the thread context classloader if it is set, and walk its |
| hierarchy, creating a context if none is found. If the thread context classloader |
| is not set, then we use the classloader associated with the current Context. |
| <p> |
| If there is no current context, or no classloader, we return null.</div> |
