The WebJar extensions client-side web libraries (e.g. jQuery & Bootstrap) packaged into JAR (Java Archive) files.

Standard WebJars, as defined by, are JAR extension but to make easier to differentiate actual JARs and WebJars a new type was introduced. For Maven project see WebJar Maven handler.

In practice it works exactly like JAR extensions except for two differences:

  • no scan to find components is applied
  • wiki administrators are allowed to install WebJars (programming right is required for JARs)
