jxl - how to install and use JExcel library in NetBeans 12

Question

I need to use the jxl library in Netbeans 12 running in Ubuntu 14.04. I have followed the directions available online:

• adding the jxl-2.6.jar file to the classpath
• placing the jxl-2.6.jar file in the same directory as the source
• placing it in a new folder called "+libs"
• adding a new library containing it
• importing the classes

and yet NetBeans is still unable to find the classes in the library, saying "the jxl package does not exist". I haven't found any instructions specifically for Netbeans 12 on linux - please let me know if they exist. It is likely that I'm missing some step in the process, so please mention all the necessary steps after download/extract the zipped .jar file.
