The class that Fuseki needs to load can be essentially anything, however when you mentioned a class with ja:loadClass all that actually happens is that the class is initialized I.e. it's static initializer block (if any) gets called. Typically you would use the static initializer block to wire up things into Fuseki e.g. adding custom query engines etc.
It is unclear exactly what you are trying to do, the example you copy and pasted (which appears to be direct from the SPIN examples) is a command line program that does a one time validation of some data against some SPIN constraints. If you use the example you gave absolutely nothing will happen since there is no static initializer block and the main() method will never get called. Presumably you are wanting to integrate SPIN with Fuseki so that you can continually validate SPIN constraints as new data is added to the system? If you can explain your goals better then you will get better answers Rob On 5/29/13 1:22 PM, "Matías Parodi" <[email protected]> wrote: >I guess this is it: http://paste.kde.org/753266/ > >I couldn't find any real example of what to put in the class Fuseki needs >to load, all I found is that I can load the class using ja:loadClass (btw, >loadClass is not even in the vocabulary, I don't know where it's >defined......) > >Am I supposed to compile the example I pasted above?
