Can't run COMPSs application. ClassNotFoundException

Question

I am learning COMPSs. Until now, everything has been working really well, but I only executed the examples given in the manual.

Now that I want to run my own test application, I can't get it to work. I must be missing something, but I can't see what I am doing wrong.

My application is called App, and has the main class App, and the interface in another class called AppItf. When I try to run it using runcompss:

runcompss -d --classpath=$PWD/App.jar App

I get the following message:

Using default location for project file: /opt/COMPSs/Runtime/scripts/user/../../configuration/xml/projects/project.xml Using default location for resources file: /opt/COMPSs/Runtime/scripts/user/../../configuration/xml/resources/resources.xml

Error running application

Can somebody help me find what I am doing wrong?

Thank you in advance!

Answer 1

In the runcompss command you have to specify the fully qualified domain name of the class. So, if this class has a package you have to add the package to the class name. It is currently missing.
