Re: [GridSim-users] Visualizator problem

[Marcos D. de A. <mar...@gm...>]

Hi Dalibor,

thanks for pointing out that problem.

The problem is that the file does not exist in the jar; that is, the ant 
build.xml file was not including the gui.properties file in the jar. 
Please use the build.xml that is attached to this e-mail to generate the 
jars again. After that, the example should work by invoking:

java -cp $GRIDSIM/gridsim.jar:. parallel.agressive.ExampleEASY01 
$GRIDSIM/examples/parallel/sdsc_blue_01.txt

Regards,

Marcos
