Apache Struts 2 provides a simple plugin architecture so that developers can extend the framework just by adding a JAR to the application's classpath (in addition to whatever JARs may be required to fulfill the dependencies of the plugin itself). Since plugins are contained in a JAR, they are easy to share with others. Here, we list plugins available for Struts 2 and provides help on how to use them.
Contributed plugins may be of varying quality. If not bundled with the official Struts 2 distribution, a plugin cannot be guaranteed to be safe. You install plugins from this space at your own risk. We do not monitor or guarantee any code posted in this space. If you find dangerous or malicious code posted here, please contact the Struts User mailing list immediately.
