Could not instantiate Seam component: register with Maven2 seam registration example

ramay Jan 26, 2009 3:36 PM

When trying to run seam registration example that has been built using Maven on JBoss 4.2.x facing the following error message after clicking the 'register' button

We have also added JBoss-el.jar and hibernate-core-3.3.0.jar to WEB-INF/lib to resolve other errors.

Any help is appreciated.

Empty seam.properties file is also present in resources directory.

binnyg Jan 26, 2009 10:04 PM (in response to ramay)

Are you building a jar file which has all your seam components and then have seam.properties in your META-INF folder? There is a very good explanation on how you can do this http://seamframework.org/Community/InfoCreatingSeamProjectInMaven2

Thanks.

We are building a war instead of ear which will have all seam components, WEB-INF, META-INF etc.

Yes, seam registration example by default provides an ear (with ant).

The interest is to build War with Maven2 as of now. In future we could go to ear though.

Did you annotate your RegisterAction with @Stateless ?
Please show us your registerAction.

Remove @Stateless and deploy your application as a war file. It should work.

Hi Binesh,

the decision has been made to go with ear instead of war and hence did not try your inputs. Apologies for late reply

With maven2 and ear, I am able to compile and package.

Thanks
