First, you have to add your external Jar files to the classpath of your current Jabaco project.
Function key F1 gets you into the "Imports" dialog to define the Jar files to be known to the Jabaco IDE.
Second, you can either use "import" statements or specify the full class names.
Once you have referenced an external class in your code, the next references can omit the full path. Try it!
See
here for an example how to access external Java APIs from within Jabaco. The programming language you are using is Jabaco. The Jabaco compiler translates Jabaco sources into Java class binary code.
Success!
