ConfigurationException: Failed to load configuration file

[Martin Wiegand]

When I try simulating Pastry in with the newest Version of the Simulator I get the following Exception when I try to use my config file:

Exception in thread “main” org.peerfact.api.scenario.ConfigurationException: Failed to load configuration from file config/ex8-FileSharing-Pastry.xml

Am I doing something wrong? Is something wrong with the config File? I have slightly altered some of the code of the Pastry classes though I can run the old code by changing a few newly introduced variables. I do not think, however, that they are related to this issue.

Thank you in advance,

Hi,

to me it seems that the error is here to be found:
file:///home/martin/Bachelor%20Arbeit/GIT-Sim/config/ex8-FileSharing-Pastry.xml

Could you check if the error occurs when you use a folder structure without spaces –> e.g. not “Bachelor%20Arbeit” but “Bachelor-Arbeit” ?

Sometimes one parameter is considered as 2 separate parameters in this case.

[Martin Wiegand]

I have changed the folder name to Bachelor_Arbeit. Sadly the problem persisted. Looking over the entry that causes the problem once more I finally found the error: the Include responsible for the errors had a normal s where it should have had a capital S. Problem solved.

Thank you, I am sorry I missed that.
