B4J Question Class not found exception

[wl]

Hi,

I installed B4J correctly (I think) and created the application as demo'ed in http://www.b4x.com/android/forum/threads/non-ui-applications.34657/.

When I run the application I get the following. What am I missing ?

Thanks !

OK, I found it ... I added the source files (as in the ZIP file) and now it works ...

In Windows it works perfectly
BUT: when running in Linux (Ubuntu) the java -cp curl.jar ... call does not return anything.

I tried all kinds of URL's (including http://www.google.com): only URL's which return very few characters eem to work. As soon as the output is a few Kb's long the call does not return anything (waits for the output to end ?)

Are you sure that you created a non-UI app? javafx is not required in this case.
