I was tasked to upgrade an old desktop app using old java and it used rt.jar and jfxrt.jar libraries. I have searched online about the libraries(rt.jar & jfxrt.jar) but apparently, it is no longer there in Java 17 and JavaFX 17. What are the equivalent libraries for rt.jar and jfxrt.jar for the latest version of Java 17 and JavaFX 17?
Regarding JavaFX and Java 17, you need to use a new JavaFX-specific SDK with all the necessary runtime dependencies here: https://gluonhq.com/products/javafx/
Also, refer here to the starting place to learn more about JavaFX: https://openjfx.io/openjfx-docs/
Note that rt.jar was removed as of Java 9, read more here: https://docs.oracle.com/en/java/javase/14/migrate/index.html#JSMIG-GUID-A78CC891-701D-4549-AA4E-B8DD90228B4B
Class and resource files previously stored in lib/rt.jar, lib/tools.jar, lib/dt.jar and various other internal JAR files are stored in a more efficient format in implementation-specific files in the lib directory.
