[OS-webwork] pico support available

[Matt Ho]

i've added pico support to xwork and webwork.   i've also updated the 
sample application in webwork to use pico.  to use pico ioc, you'll need 
to put the following to your web.xml file:

<listener>
<listener-class>com.opensymphony.webwork.lifecycle.PicoApplicationLifecycleListener</listener-class>
</listener>
<listener>
<listener-class>com.opensymphony.webwork.lifecycle.PicoSessionLifecycleListener</listener-class>
</listener>
<filter>
<filter-name>container</filter-name>
<filter-class>com.opensymphony.webwork.lifecycle.PicoRequestLifecycleFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>container</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
Save the class names, this is probably the same as what you already 
have.  You'll need to remove the ComponentInterceptor from the 
interceptor stack as this isn't needed anymore.

Additionally, your components.xml file will need to be configured a 
little differently.  Whereas before you would have:

<component>
  <scope>application</scope>
  <class>HibernatePersistenceManager</class>
  <enabler>PersistenceManagerAware</enabler>
</component>
with a class that looked like:

public class Foo implements PersistenceManagerAware {
  private PersistenceManager persistenceManager;
  public void setPersistenceManager(PersistenceManager 
persistenceManager) {
    this.persistenceManager = persistenceManager;
  }
}

You'll now have:

<component>
  <scope>application</scope>
  <class>HibernatePersistenceManager</class>
  <enabler>PersistenceManager</enabler>
</component>
with a class that looked like:

public class Foo {
  private PersistenceManager persistenceManager;
  public Foo(PersistenceManager persistenceManager) {
    this.persistenceManager = persistenceManager;
  }
}
My intent is to put it out there for comment and then replace the 
existing IoC framework once this one is solid.  As one small step 
backwards, the pico implementation does not yet support the Startable, 
Stoppable, or Disposable interfaces.  I'll add that today or tomorrow.

Cheers!
