pack:tag: Compressing JSP Taglib

Category: Java, JavaScript, Library

pack:tag is a static-resource compressing JSP-Taglib. It caches ad hoc compressed JavaScript or CSS in memory (in a Java Servlet) or in a generated file. It works transparently to the developer and the compressing-algorithms are pluggable.

Features

  • Minification of JavaScript and Cascading Style Sheets
  • Caching to filesystem or memory (servlet)
  • When caching to memory, the minified content is additional gzipped
  • Apache Standard Taglib support for evaluations
  • Compression and hashcode-generation adjustable on single resources

Examples

You would use JSP tags such as the following in your JSP files:

  1. <pack :script src="myJavaScriptFile.js"/>
  2. <pack :style src="myCascadingStyleSheet.css"/>
  3. <pack :script src="myJavaScriptFile.js" enabled="false"/>
