Dandelion datatables not working on Liberty profile

Question

So I have this test application for simplistic sake. I have it working in Tomcat, but when I deploy the same war to a Liberty profile server it doesn't work. None of the bundleSources or ResourceScanner gets invoked.

Configuration

@Configuration
public class WebConfiguration
{
    @Bean
    public DandelionDialect dandelionDialect()
    {
        return new DandelionDialect();
    }

    @Bean
    public DataTablesDialect dataTablesDialect()
    {
        return new DataTablesDialect();
    }

    @Bean
    public Filter dandelionFilter()
    {
        return new DandelionFilter();
    }

    @Bean
    public ServletRegistrationBean servletRegistrationBean()
    {
        return new ServletRegistrationBean(new DandelionServlet(), "/dandelion-assets/*");
    }
}

and it continues to loading with Resource loader.

None of the Resources are found why?

Answer 1

Found the issue in the ResourceScanner class. Websphere application servers use a jar naming convention of wsjar. I created a fix here https://github.com/ohiocowboy/dandelion/tree/feat/liberty
