So I'm trying to write a print library for Lucee. Everything's working great in the IDE, but when I make a .JAR and bring it into Lucee, I'm getting Lucee 6.0.1.83 Error (java.lang.NoClassDefFoundError) javax/print/attribute/standard/Media I made a test program (and .JAR) and I found that Lucee's able to use javax.print no problem (for instance I can get the printServices installed on a PC), But it's acting like javax.print.attribute.standard.Media just doesn't exist. AFAIK this has been standard to Java for ages, so I don't understand why Lucee's unable to see it. What's up with that? Version: Lucee 6.0.1.83 (Mar 18, 2024) Java: 11.0.6 (AdoptOpenJDK) 64bit (Sample code attached. Sry I know it's quick & dirty.) Any help would be appreciated.
