[GridSim-users] RIPRouter Exception on RegionalGIS Example

[Alex G. <fro...@ya...>]

I posted this before and no one answered. If anyone has any clue please help solve this.

"when running the RegionalGIS example
(example.regionalGIS) from the package examples if i change the number
of Regional GIS to 1 (i.e only one RegionalGIS) i get the following
exceptions:

///////////////////////////////////

///////////////////////////////////
