All Implemented Interfaces:

Serializable, javax.servlet.jsp.tagext.BodyTag, javax.servlet.jsp.tagext.IterationTag, javax.servlet.jsp.tagext.JspTag, javax.servlet.jsp.tagext.Tag

public class YUIMinTag
extends javax.servlet.jsp.tagext.BodyTagSupport

The YUIMinTag is the JSP custom tag to expose the YUICompressor functionality in the JSP.

Using the YUIMinTag inline css, js, json can be compressed.

Usage

Put the webutilities-x.y.z.jar and yuicompressor-x.y.z.jar (See dependency mentioned below) in your classpath (WEB-INF/lib folder of your webapp).

Declare the taglib and prefix in your JSP

 <%@ taglib uri="http://webutilities.googlecode.com/taglib/yuimin" prefix="ymin" %>
 

Use the tag to minify your inline JavaScript

 <ymin:minify type="js">
        ...
        // your inline uncompressed JavaScript
        ...
 </ymin:minify>
 

You can also similarly use the tag to minify your inline style

 <ymin:minify type="css">
        ...
        // your inline uncompressed CSS
        ...
 </ymin:minify>
 

Attributes

The YUIMinTag also supports the different attributes similar to YUICompressor's command line options. Below are the attributes and their explanations. all attrinutes are optional except type.

  type - possible values are js or css. The only required attribute. Usage as shown above.
  lineBreak - equivalent to YUICompressor --line-break. Insert a line break after the specified column number
  noMunge - equivalent to YUICompressor --nomunge. Minify only, do not obfuscate.
  preserveSemi - equivalent to YUICompressor --preserve-semi. Preserve all semicolons.
  disableOptimizations - equivalent to YUICompressor --disable-optimizations. Disable all micro optimizations.
 

Dependency

The YUIMinTag depends on jsp-api and YUICompressor jar to be in the classpath.

jsp-api.jar - Must be already present in your webapp classpath

yuicompressor-x.y.z.jar - Download and put appropriate version of this jar in your classpath (in WEB-INF/lib)
