B4J Question [SOLVED] ABMaterial - how to get the template project to work ?

Dear all,
I've installed ABMaterial, and I'm following this tutorial:

I've downloaded the lesson2.zip and put in the template folder of ABMaterial overriding all the files, as suggested. I'm running the latest version of B4J and ABMaterial has the version 4.30

Then I've loaded the template.b4j project and run it.

In the browser (firefox) I then open the address http://localhost:51045/template/
but only a coloured circle animation occurs, and in the log of B4J idle I read at the end:
Trying to open: http://localhost:51045/template
Not Found
Not Found

In the ABMShared there is this command:
Public AppName As String = ""
which I changed then to
Public AppName As String = "template"
But it does not work either.

Here the complete log from the idle.

This thread about using chrome to find out missing files was really helpful : https://www.b4x.com/android/forum/t...primary-page-of-the-webapp.97936/#post-617270

The files that were missing - comparing the template project in lesson 2 with the demo, were:

Note that the tutorial file "ABMaterialForDummies.zip" does not have these files, that's why it did not work !

Once copied the files to the related directories of the template project, everything has worked as expected.

May be is helpful for someone else having the same prob.. hem, challenge ;-)

Go on you for getting through that issue.
I just wonder if any others that have gone through these lessons had experienced the same issue?
That issue, I have heard from to date, until now.

I know this thread is a few months old but I'll confirm I have literally just had the same issue (I'm just starting out with ABMaterial).

I didn't use the Chrome method as you did @semar - When I tried running the lesson2 template and accessing it in my browser there were mentions of the three files being missing in the b4j log window.

For others reading, you can find the files in the template folder of the ABMaterial (4.3 in my case also) dowload, they're just not included in the lesson zip file I assume because of its age and they weren't originally required with older versions of ABMaterial.

I was going to post up a thread describing my issue and fix but you have already done it perfectly!
