TomEE 7.0.3 (i cannot upgrade to 7.0.4)

i am trying to switch from using XSLT to using velocity templates. i
noticed that velocity was included as a lib in TomEE

if i declare VelocityEngine inside a CDI @ApplicationScoped
try {
            VelocityEngine velocityEngine = new VelocityEngine();
            velocityEngine.init();
            Template t =
velocityEngine.getTemplate("velocity/reports/note.vm");
            VelocityContext context = new VelocityContext();
            context.put("note", note);
            StringWriter writer = new StringWriter();
            t.merge(context, writer);
            System.out.println(writer.toString());
        } catch (ResourceNotFoundException e1) {
            e1.printStackTrace();
        } catch (ParseErrorException e1) {
            e1.printStackTrace();
        } catch (MethodInvocationException e1) {
            e1.printStackTrace();
        } catch (IOException e1) {
            e1.printStackTrace();
        } catch (Exception e1) {
            e1.printStackTrace();
        }

then i get

is VelocityEngine not allowed in there? or is there somewhere else i
can be defining it for general use inside the container?

Hi

If you keep the bean and remove velocity you will probably get the same
error until its classloader is not correctly set and you have extensions in
your webapp but it should fail at runtime.

if i remove velocity from NoteDao then TomEE starts fine

btw is there some way to define VelocityEngine as a Resource in
tomee.xml so it doesn't have to be loaded each time?

Then you can use the force-load option if you have velocity in your app or
remove it from here to use tomee one

That said tomee should only need velocity in embedded mode and not others
so maybe a dependency leak to fix if not already.

i didn't add velocity in my app i was trying to use the TomEE one. i
moved the code out of the @ApplicationScoped and into a @Named and the
container started but then the @Named bean resolved to null
javax.el.PropertyNotFoundException: Target Unreachable, identifier
'eventsBean' resolved to null

Means the bean is vetoed, probably cause the class cannot be loaded
surprisingly.
