CDI doesn't recognize backingbean

i'm trying to learn how to use javaee 6 CDI feature on JSF 2.
But, the container seems doesn't recognized my customized backing bean at the runtime.
Below is my execution environment and the code snip.
Every response is appreciated about how to solve this problem.

Platform : Eclipse 4.2 Juno / WebLogic 12c
Scenario : User request for the "start-page.xhtml" ,and then click on the button , redirect to the "page1.xhtml"

The start-page.xhtml code

The page1.xhtml code

The backing bean

web.xml

beans.xml

and the runtime error

Error 500--Internal Server Error

Debug EJB 3.0 project in Eclipse 3.7 with Oracle WebLogic 12C server

hello guys, i'm trying to debug mdb in eclipse with weblogic 12c.
In my project , i add the log4j.jar , hibernate-core jars.... etc in it.
but , when i publish the project to server , it's fail on EJB preparing phase.
as the following error code

<Deployer> <BEA-149078> <Stack trace for message 149004
weblogic.application.ModuleException: Exception preparing module: EJBModule(CibEJB)

Base on the preceding messages, i check the weblogic startup classpath to see if there is another log4j.jar be loaded but none.
Is there any other issue that i haven't noticed to sovle this problem ?

WebLogic12C + Eclipse Indigo develop JSF 2.0 with CDI

Oracle weblogic 12c has just released recently. I'm trying to develop jsf 2.0 with managed bean using injection mechanism on it.
But, only when i annotated the bean with @Managed , the backing bean did work.
If annotated the backing bean with @Named , that the backing bean didn't.
So, i supposed that is the CDI implementing jar is not correctly setup on classpath, but where is it ?
Just find out all the eclipse workspace and oracle lib folders , haven't see it.
anybody who has fallen in struggled like me ?

hello, guys ..
i found the tricky problem is that should put a empty but include the <beans> tag beans.xml file.
But i'm still confused with this empty file, is it play a key role with weld.jar ?
Here are my project settings.

Is there exist a deadline to pass the ocmjea part2 after part1

Jeanne Boyarsky wrote:Kim,
Welcome to CodeRanch! While I don't recall a specific deadline, I think it should be done on a timely basis. Once Oracle changes the exam numbers (such as when they upgrade to JEE 6), I can't imagine the old one will be valid forever.

Thanks for you reply , Jeanne.
So, maybe i should firstly gather the essential knowledge and skills for the part2 exam , it seems as soon as possible will be better

Is there exist a deadline to pass the ocmjea part2 after part1

hi , everybody,
i'm new to this forum, yesterday i did passed the part1 exam.
Regarding to the Oracle online certificate document , the part 2 exam provides 6 months to prepare & document the essential documents to submit,
but, is there still exist a restriction that how long ( ? months or ? yrs ) should i start the part2 exam after passed part1 exam ?
