Cannot access static html resources in a tomee-embedded application that publishes classpath as webApp

Question

I am trying to configure a tomee-embedded in an application. All classes and html files are in the same gradle project so the tomee-embedded serves the classpath as a webApp.

I can verify that EJB and Servlets are working and so are webservices.

However it seems that the html static resources that are found in /src/webapp are not served. I cannot access for instance the index.html that is in /src/webapp/index.html, nor any of the other files and folders.

I have tried some approaches, like the ones shown below.

• Adding the webapp folder as CustomWebResources in the Configuration.

• Adding the webapp folder as docBase when deploying classpath as webApp.

  public final class Main {

  public static final void main(final String[] args) {
  
   final Configuration configuration=new Configuration();
  
   //Attempt one, does not work
   configuration.addCustomWebResources("webapp");
   configuration.setHttpPort(8082);
   try (final Container container = new Container(configuration)) {
  
       //Attempt two, does not work either
       final File docbase=new File("webapp");
       System.out.println("Docbase:"+docbase.getAbsolutePath());
       container.deployClasspathAsWebApp("/",docbase);
       System.out.println("Started on http://localhost:" + container.getConfiguration().getHttpPort());
  
       container.await();
   } catch (final Exception exception) {
       LOGGER.error(ExceptionUtils.getStackTrace(exception));
   }
  

  } }

For reasons of completeness the gradle import I use is the following:

  implementation 'org.apache.tomee:tomee-embedded:8.0.6'

How can I tell the tomee-embedded to also serve the index.html and the other resources under src/webapp folder?

Answer 1

I was finally able to figure this out. The following will work when running with the "run" task of the gradle application plugin.

   public final class Main {

   public static final void main(final String[] args) {
    
    final Configuration configuration=new Configuration();
    configuration.setHttpPort(8082);
    try (final Container container = new Container(configuration)) {

        //Works in gradle application:run
        final File docbase=new File("src/main/webapp");
        System.out.println("Docbase:"+docbase.getAbsolutePath());
        container.deployClasspathAsWebApp("/",docbase,true);
        System.out.println("Started on http://localhost:" + container.getConfiguration().getHttpPort());

        container.await();
    } catch (final Exception exception) {
        LOGGER.error(ExceptionUtils.getStackTrace(exception));
    }
    }
    }

The docbase should point to the exact location of the webapp folder. This means that in an actual implementation distribution the relative src/main/webapp should be replaced by the actual webapp folder location.
