Hi !

I am having some trouble with the "Simplets Hello World Portlet" on GateIn.

I am very beginner for this installation and I would appreciate if someone can help me out.

Following is little bit of introduction with my platform,

OS : CentOS v 6.3 64 bit

Installed package : JBOSS AS 7 + GateIn 3.5

   I have used the GateIn-3.5.0.Final-jbossas7.zip for the installation.

Maven : apache^maven-3.0.5

Databse : default HSQL

I have confirmed that JBOSS AS 7 started properly by accessing the admin console

and also followed the README.md for creating the project.

But when I got to the following part and pointed the browser to http://127.0.0.1/portal.classic,

  * Point your web browser at the base URL of your portal (URL of a default local GateIn Portal installation is

  [http://127.0.0.1:8080/portal/classic](http://127.0.0.1:8080/portal/classic)).

  * Sign in as root or other user with manager:/platform/administrators permissions.

  * Go to Top Menu > Group > Administration > Application Registry and hit Import Applications. After that, you should

nothing was shown there was following errors in the server.log,

Caused by: java.lang.RuntimeException: Cannot instantiate component key=org.exoplatform.web.WebAppController type=org.exoplatform.web.WebAppController found at jndi:/default-host/portal/WEB-INF/conf/portal/controller-configuration.xml

Could someone give me an advice about what I am lacking in the setting?

I have not changed any settings in any of the configuration files that are in the JBOSS HOME directory.

Thanks,
yu
