Re: [Repast-interest] NoClassDefFoundError: repast/simphony/dataLoader/ContextBuilder

[Nick C. <nic...@gm...>]

Hi,

The typical Repast S launch classpath will contain the JDK and the  
Repast S runtime code (repast.simphony.runtime project). The model  
code is loaded via paths specified in the model.score file. This model  
code can be the model itself and any other 3rd party code including  
for example the dependent project.

This thread might help a bit:
