Although the dialog indicates icefaces-ace.jar is optional, it is
necessary for the NetBeans-generated markup to work properly.
We then need to click on the Create ICEfaces library button, give the library an
appropriate name (like ICEfaces ), and click on OK .
After clicking on OK , we need to locate the ICEfaces JAR files on the filesystem by
clicking on the Add JAR/Folder... button to add them to our library.
