Runtime Error
Emma Osborne
4 Posts


I am using your latest version of EJS for Mac and each time I try to compile a simulation Ejs reports runtime error=143. This arises when trying to compile my own programme and other complete programs e.g. those included in modelling science.

This runtime error prevents me from running my simulations, so I am unable to see how they are developing when I change aspects of the simulation.

Could you please help me with this??

Many Thanks!

Hi Emma,

I need some more information. Do you get a  long error message in the console? If so, please copy and paste it here, so that I can inspect it.

I am a Mac user myself and EJS works fine for me. (Make sure you have Java 1.7 installed. And NOT the Java 1.6 that comes with MacOS X. You need 1.7 to run EJS 5.0 beta. You can run EJS 4.3.7 with Java 1.6.)

Hi Francisco,

Thank you very much for your prompt reply. I have now updated my Java and it seems to be working fine now.

Thanks again for your help
