Thread: <param-value> in web.xml whith Jersey

Hello every one,

I am just get confused because the web.xml data when i using REST Web Service using Jersey

now i have 3 Packages, and every package contain at least one jersey class.

Now when i want to run the project i get always this error

HTML Code:

com.sun.jersey.api.container.ContainerException: The ResourceConfig instance does not contain any root resource classes

so after looking for the cause the problem, i notice that all about <param-value> tag

so when

HTML Code:

<param-value>Project's name</param-value>

i got always that error but when i switch it to

HTML Code:

<param-value>package's name</param-value>

it works just only if i run the calss from the same package but when run another class from another package i got again the same error

HTML Code:

          <param-name>com.sun.jersey.config.property.packages</param-name>
          <param-value>???</param-value>
        </init-param>

so what the problem
