Thank you for reporting this error and I apologize for the problem.

The fix has been made and it will be published tomorrow.

The problem is in the deployment code in the tutorial module that builds the classpaths, etc. for the demo.sh and demo.bat file. It uses a rootspace identifier to obtain the physical location of the module. The rootspace identifier was changed during the final edit of the tutorial and I missed making the change in this code.

I''m playing with the embedding tutorial and while trying to extract http://localhost:1060/embedded/demo/extract
I''ve got a java.lang.NullPointerException: Cannot invoke method getOwningModule() on null object. But apparently it extracts the folder (I wonder if the error would be that I might clicked it twice?).

I have no "demo.sh" (or "demo.bat") there, only build.xml, Main.java and kernel.properties. However ant compule runs fine.

Then you say that you will find the module under /modules/urn.org.netkernel.tutorial.embedded.module/ note that it is actually /modules/urn.org.netkernel.tutorial.embedded.module-1.1.0/

having no demo.sh I tried to run like this

embedded-demo$ java -cp ../lib/*:src/ Main /opt/1060-NetKernel-SE-4.0.0-rc3

I suppose that I''m missing things due to thhe error in extracting the package; I removed the embedded-demo folder and tryied again the extraction, and I get NPE:

java.lang.NullPointerException
Cannot invoke method getOwningModule() on null object


Retry the request.
