How to invoke a Seam Component from a plain JMX MBean or EJB

[jonathandfields]

Hi All,

Newbie question...

I have some Seam Components that I'd like to be able to call from a thread launched in a JMX MBean in JBoss. The thread implements a hot folder, parsing files dropped into the folder, and updating a DB via the Seam Component.

Since I cannot use injection in the MBean to get a reference to the component (it's not a Seam Component or an EJB), what is the best/correct way to obtain such a reference? Can I do a JNDI lookup as I would for a plain EJB?

Same question for a plain EJB (non Seam Component). Can I use EJB injection to get a reference to the EJB that underlies the Seam Component.

Thanks,
Jon

Use Component.getInstance(<class>/<seam component name>)

Hi Benjamin

I tried to use the method that you mention above but with no luck. I get an exception No application context active when invoking one the jmx methods. The component i am trying to use is Application scoped. Should i annotate that component in a certain way? Are there some configuration that i am missing?

Thank you in advance
Albert

You'll need to start the lifecycle yourself. Look at ContextualHttpServletRequest for inspiration.
