Work-light: Issue with setting up the environment

Question

I have started learning IBM worklight recently.I have set the environment.

Now, I am trying to test a simple helloWorklight demo app but i am not able to do deploy and build the app.Although i am following this link: http://www.ibm.com/developerworks/mobile/worklight/getting-started.html

The error what i am getting is.. when trying to run on worklight development server:

Also my worklight console is not opening, error is:

Failed to deploy the application to Worklight server: Internal Server Error; Error 500: javax.servlet.ServletException: Filter [authenticationFilter]: 
Could not find required filter class - com.worklight.core.auth.impl.AuthenticationFilter.class 

Answer 1

Verify server.xml file of Worklight Development Server.

Check all <library> tags make sure they are pointing to correct path.

Cheers !!

Answer 2

Wise advise on validating all tags. To begin with, where is 'shared.resource.dir' declared? Wherever it is, the path to it supposedly is '/usr/shared/resources', where we can crawl into the subdirectories and find the corresponding libraries. I found out that a db2 library contained in db2 directory right below resources does work, whereas that in db2 directory below worklight subdirectory, albeit more recent, does not work. Therefore, I copied and replaced the ailing one with the good one... :-) and, well, at least the error message became different. :-D
