I think more context is needed to answer your question.

I can think of a couple ways to use Java classes in Ignition but I don’t know if these ways are applicable to you or not.

The easiest way to use Java classes in Ignition is through Jython scripting. Examples are here: [inductiveautomation.com/support/ … g\_java.htm](http://inductiveautomation.com/support/usermanuals/ignition/index.html?accessing_java.htm)

If you want to program directly in Java then you can do that using the IgnitionSDK: [inductiveautomation.com/news/item/257](http://www.inductiveautomation.com/news/item/257)
