Hi,
I met a problem when deploying a Jersey based project in JBoss AS 5.0.1.GA. The exception was:
03:14:56,344 ERROR [STDERR] Jun 18, 2009 3:14:56 AM com.sun.jersey.api.core.PackagesResourceConfig init
INFO: Scanning for root resource and provider classes in the packages:

My Jersey servlet configuration is as following:
...
<servlet>
<servlet-name>Sample Resources</servlet-name>
<servlet-class>com.sun.jersey.server.impl.container.servlet.ServletAdaptor</servlet-class>
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>org.example.rs</param-value>
</init-param>
<init-param>
<param-name>com.sun.jersey.config.feature.Redirect</param-name>
<param-value>false</param-value>
</init-param>
<load-on-startup>0</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Sample Resources</servlet-name>
<url-pattern>/sample/*</url-pattern>
</servlet-mapping>
...
This package is deployed successfully in JBoss 4.x. I note that this issue was fixed in Jersey 1.0.1. It should not reproduce again. Did I configure wrongly somewhere?
Thanks,
William
