Can any one tell me, how do i use java classes and methods(.Jar file) in ignition?.
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
If you want to program directly in Java then you can do that using the IgnitionSDK: inductiveautomation.com/news/item/257
