Re: [jetty-users] Jetty 9.2.x - Annotations

[krumpi <krumpi@xxxxxx>]

Jan,

Thanks for the answer, I'll compare the project with the test-spec.war.

The @PostConstruct is declared as annotation on simple JSF-managed-beans.


Following two examples not working:

 --------------------------------------------------------------------
| 1) simple managed bean which is declared in the "faces-config.xml" |
 --------------------------------------------------------------------

<managed-bean>
  <managed-bean-name>
    treeController
  </managed-bean-name>
  <managed-bean-class>
    myJarProject.control.impl.TreeController
  </managed-bean-class>
  <managed-bean-scope>
    session
  </managed-bean-scope>
</managed-bean>

This bean contains 2 methods:
-----------------------------

@PostConstruct
public void initController() {
}

public MyTree getTree(){
}

Executing the method:
---------------------

Only the "getTree" is called manually via "treeBB"-backing-bean
("this.treeController.getTree()") .

<h:outputText value="#{treeBB.tree}" escape="false" id="mainTree"/>

Comparison Jetty 9.1.5
------------------------
The initController-Method is correctly called in Jetty 9.1.5, but never
called in Jetty 9.2.x.

 --------------------------------------------------------------------
| 2) eager-loading bean which is declared in the "faces-config.xml". |
 --------------------------------------------------------------------

<managed-bean eager="true">
  <managed-bean-name>
    applicationModeController
  </managed-bean-name>
  <managed-bean-class>
    myJarProject.appMode.ApplicationModeController
  </managed-bean-class>
  <managed-bean-scope>
    application
  </managed-bean-scope>	
</managed-bean>

@PostConstruct
public void init() {	
}

Executing the method:
---------------------
The bean should be created when the application starts (eager-loading)
and then the init-method should be processed.

In this init method there are some class member variables set, which are
read via static method after application-start, so the eager-loading is
necessary here.

Comparison Jetty 9.1.5
------------------------

The eager-loading doesn't work in Jetty (incl. 9.1.5), so I had to
implement a workaround in the getter-methods, to set the variables.
