I'm using cplex in java and i have a runtime error. 

The eclipse shows me this error : 

I think this error is relative to the size of my instances but the problem that i used other larger instances and they are well executed. 

Any one can help me ? 

Best regards.

Hi

you call cplex community edition which is a limited version and you reached the limit.

To go further you could either move to the free academic version or to a commercial version.

You could also try the cloud version

(docplexcloud)

Is there another way?

Hi,

you should find some way to prove your academic status.

In the meantime, you could use cplex in the cloud
