Problem instantiating a component

mo2p Aug 14, 2008 2:33 PM

Im trying out an example for registration...

as soon as i want to use it in the register.xhtml for an value or action that
does use {newMember.memberName} or {registerService.password} it crashes with
the error message below ...

i really tryed now for a few hours (about 7) to solve this, but with out result, im still
new to seam :-) so maybee it's something relly stupid that im missing...

thanx a lot for any help

PS: i only posted the actual snippets that i was testing to evaluate where the mistake is...

Show your components.xml. I guess there is a problem (jndiPattern). Also check log if whole deployment was successful.

Make sure your Register interface has a @Local on it.

6. Re: Problem instantiating a component

sjmenden Aug 14, 2008 4:00 PM (in response to mo2p)
There is probably a nested exception that tells the cause. So there are further problems I see. You need a:

@Remove @Destroy public void destroy() {}

in your Register Action and:

@Local public interface Register { public void destroy(); }

And you will need to define any methods used in your RegisterAction in your Register interface like:

@Local public interface Register { public void destroy(); public void register(); }

If you still have problems after doing this post the full stacktrace.

thanx for the help, i really have no clue what i do miss...

8. Re: Problem instantiating a component

Unless I am missing some simple syntax mistake, it is probably one of a few issues:

RegisterAction/Register placed in the wrong location

Messed up classpath/config

Wrong jndiPattern (probably not though if this is a default seam-gen)

So, what I'd like you to do is this, backup and remove your existing RegisterAction/Register classes, go to your SEAM_HOME dir where you created project from, and do './seam new-action' and answer the questions, this will ensure that the files are generated to the right locations. Test out what it generates, make sure it all works, then you can begin adding your custom code.

If that fails, that means something is fubar in your project, create a new project (seam setup and seam new-project) and new-action like above, it will work.

This looks like a possible jndi-pattern problem as stated before. In order for you to get your components.xml working like you have it, components.properties must be in the classpath of your EAR and have properties like:

jndiPattern yourApp/#{ejbName}/local

i did what u told me and regenerated all, rewrote it and used most of the booking example, still get the bound problem...

but maybee its not a code problem ...

im using JBoss Tools nightly build to generate seam-gen stuff and i use war not ear...
maybee this is the main problem im trying now to genereate it outside with seam-gen apart from jboss tools...

i will write later if i was successful

Mystery solved, WARs don't support EJB3s, you'll get the message you are seeing. Regen your project and select EAR and it will work, of course, then, you can't deploy, but why do you need EJB3s to begin with? it definitely isn't necessary for your registration bean. Unless you need the additional functionality of EJB3s, you'd do better with a WAR project.
