I am a new user of Nessi2 and i need help. I am currently having issues running my simulations. please can some one help with me with links to sample projects that i can learn from. In addition, i will also like to know how i can import sample projects into my nessi2 instance.
I will also like to know if few simulations can be run without installing mySQL using the SQL Lite.
I appreciate your prompt reply.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
In the folder for version 2.1.1-beta is a file called Example-Simulation.zip. This file contains an example project, simply unzip it and import it to NeSSi2.
In the "File" menu you can find an import option, use that to import an existing project.
For running a simulation you always need a database, since NeSSi2 store and retrieves all simulation events from the database. There is no mechanisms to view a simulation during execution.

Thank you so much for your response. I have installed the MySQL database and also downloaded and imported the simulation example. However, each time i attempt to run the backend, I encounter this error "JAVA_HOME variable is not set correctly" Please where and how do I set the this variable.
Thank you for your prompt response

Dear Kasten
Thank you so much for your response.
I have been able to resolve the JAVA_HOME issue. However, while attempting to run the simulation i encountererd this error Could not connect to backend "Failed to retrieve RMIServer stub: javax.naming.CommunicationException [Root exception is java.rmi.ConnectIOException: non-JRMP server at remote endpoint]"
Kindly help as the backend appears to be running well.

Please have a look at:
