What is a library wrapper module and how do I use it?
If your module uses some external library, you will probably use a wrapper module to make classes from that library available to your module at runtime. A wrapper module is a module that contains no code; really the only significant thing about it is its manifest, which does two significant things, in addition to the standard module unique ID/version/etc.: • Has a Class-Path entry for one or more JARs, conventionally in the subdirectory ext/ of the directory where the module is. • Declares OpenIDE-Module-Public-Packages followed by a list of the packages from the library that other modules should be able to use. You can use File > New Project > NetBeans Modules > Library Wrapper Module to make a library wrapper. So a wrapper module acts as a proxy to turn a library into a NB module. Since you can’t modify the NetBeans classpath directly (DevFaqNetBeansClasspath), nor would you want to, this is the way you let your code use third-party libraries. It serves the same function that running
