Lightweight 2 SM Bean - Problems with resource injection??
Hi,
I've start to work to port the features of Lw-container pojo to sm bean,
but i've
find a problem.
I've developed and deployed a simple process containing a simple Bean where
i've used the following syntax:
@Resource
private DeliveryChannel channel;
to get the channel injected to my pojo
The code of the onMessage method looks like:
public void onMessageExchange(MessageExchange exchange)
throws MessagingException {
if (channel == null){
System.out.println(" **************** Channel is null
****************");
}else{
System.out.println(" **************** Channel is not null
****************");
}
}
I've no problem to deploy this, the problem is that the channel is
always null, it means it's not
injected correctly.
Any Idea on that??

Definitely yes!!!
The possible solution are two:
1) Copy the geronimo_annotations.jar in the \SMX_HOME\lib where you've
put the jar containing the
bean class.
2) Put the jar containing the bean, in the service unit so the
classloader for both bean and resource is the
su classloader
The first one fits better my requirements beacuse i don't want the code
generators for pojo bean take care of
which jar to include in the su, but all the solutions are quite good.

I guess the problem is then that the annotation will not be available from
the classloader that loads your class. You should try putting the
commons-annotation jar in the container classpath then.

Re: Lightweight 2 SM Bean - Problems with resource injection??
Posted by Andrea Zoppello <zo...@tiscali.it>.
Hi,
In previous post i miss to say that the jar containing the bean class is
not in the su, but in servicemix classpath.
Is this a problem??
With the old lw-container this was not a problem...

Can you check that your SU does not include the common-annotation jar wich
includes the @Resource annotation ?
If it does, there will be a problem where the two annotations won't be from
the same classloader and the component will not recognize it, hence no
injection will occur.
Other than that, I've no clear idea why it would not work.
