I am deploying web application having jersey 2.25 on WebSphere 8.5.5.9. We are registering resources via below class.

public class ApplicationResourceConfig extends ResourceConfig {



/**

 * 

 */

public ApplicationResourceConfig() {

    packages(verifyAndLoadResources());

}



/**

 * @return

 */

private String getAllResources() {

    List<String> resources = new ArrayList<>();

    resources.add("com.ofs.fsapps.commonapps.appPreferences.resource.AppPreferencesResource");  



    resources.add("com.ofs.fsapps.commonapps.summary.rest.Summary");

    return resources.toArray(new String[0]);

}



/**

 * @return

 */

private String verifyAndLoadResources() {

    List<String> packageResourceList = new ArrayList<>();

    for (String resource : getAllResources()) {

        try {

            Class<?> result = Class.forName(resource);

            if (result != null) {

                register(StringUtils.substringAfterLast(resource, ".") + ".class");

                packageResourceList.add(StringUtils.substringBeforeLast(resource, "."));

            }

        } catch (ClassNotFoundException e) {

            System.out.println("Package/Class not Found : "+resource);

        }catch(Exception e) {

            System.out.println("Exception in loading Package/Class : "+resource);

        }

    }

    return packageResourceList.toArray(new String[0]);

}



}

With above approach, none of the rest calls are working and responding as 404. If we make entry of packages/classes in web.xml then everything is working properly.

    <servlet>

    <servlet-name>CommonRESTServlet</servlet-name>

    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>



    <init-param>

        <param-name>jersey.config.server.provider.classnames</param-name>

        <param-value>com.ofs.fsapps.commonapps.summary.rest.Summary, com.ofs.fsapps.commonapps.appPreferences.resource.AppPreferencesResource</param-value>

    </init-param>

</servlet>

Please note that shared library has been created and the same is linked with EAR as well.

Below are exceptions in SystemErr.log.
