1.8 ot 30: <h4 id="source">Download the source</h4>
1.1 plehegar 31: <p>
32: The <a href='http://dev.w3.org/cvsweb/2002/css-validator'>CSS validator</a> is available for download using CVS.
33: Follow the <a href='http://dev.w3.org/cvsweb/'>instructions</a> to
1.4 plehegar 34: access the W3C CVS public server and get 2002/css-validator. Note
1.8 ot 35: that the online version of the CSS Validator is generally older than the CVS
36: version so results and appearance may vary slightly...
1.7 ot 37: </p>
1.8 ot 38: <h4>Download as java package (jar or war)</h4>
39: <p>TBD... we just need a stable location to put jar/war archives on a regular basis</p>

41: <h3>Installation guide</h3>
42: <p>The CSS validation service is a servlet software, written in Java. It may be installed on any servlet engine,
43: and can also be used as a simple command-line tool.
44: The official W3C CSS Validation service is running with the Jigsaw server, which is the recommended setup.
45: However, for the sake of simplicity, we will, in this document, mostly provide details on how to install
1.8 ot 46: it as an online servlet with Apache's servlet engine Tomcat.</p>
1.7 ot 47:
48: <p>Some instructions on installing the servlet with Jigsaw, as well as running it from a command-line environment,
49: are also given below. </p>

1.8 ot 51: <h4 id="prereq">Prerequisites</h4>
1.7 ot 52:
1.8 ot 53: <p>This installation guide assumes that you have downloaded, installed and tested: </p>
54: <ul class="instructions">
55: <li>A working java environment,</li>
56: <li>The <a href="http://ant.apache.org/">Ant</a> java building tool</li>
1.9 ot 57: <li>A java Web servlet container such as
1.8 ot 58: <a href="http://www.w3.org/Jigsaw/">Jigsaw</a>, <a href="http://tomcat.apache.org/">Tomcat</a> or
59: <a href="http://www.mortbay.org/">Jetty</a> if you plan on using the validator as an online service.
60: This guide only covers Tomcat and Jigsaw in details.</li>
61: </ul>
62: <p id="prereq-libs">For the installation of the validator onto your system, you will
63: need to download and/or find in your system a number of java libraries:</p>
64: <ul class="instructions">
65: <li>servlet.jar
66: (which, if you have Tomcat installed in [<span class="const">TOMCAT_DIR</span>],
67: you should find in [<span class="const">TOMCAT_DIR</span>]/common/lib/, possibly
68: under the name servlet-api.jar. If not, get it at
69: <a href="http://java.sun.com/products/servlet/download.html">java.sun.com</a></li>
70: <li><a href="http://jigsaw.w3.org/Devel/classes-2.2/20060329/">jigsaw.jar</a></li>
71: <li>xercesImpl.jar and xml-apis.jar (which can be downloaded with
72: <a href="http://www.apache.org/dist/xml/xerces-j/">xerces-j-bin</a>).</li>
1.7 ot 73: </ul>
74:
1.8 ot 75: <h4>Install the CSS Validator with Tomcat</h4>
76: <ol class="instructions">
1.7 ot 77: <li>
1.8 ot 78: Download validator as explained <a href="#source">above</a>.
79: </li>
80: <li>Copy the whole source folder ("<span class="dir">.../css-validator/</span>") to the <span class="dir">webapps</span>
81: directory within your installation of tomcat. usually, this will be
82: <span class="dir">[<span class="const">TOMCAT_DIR</span>]/webapps/</span>.
83: The Validator's sources are now in <span class="dir">[<span class="const">TOMCAT_DIR</span>]/webapps/css-validator</span>,
84: which we will now call <span class="dir">[<span class="const">VALIDATOR_DIR</span>]</span>.
1.7 ot 85: </li>
1.10 ot 86: <li>In "<span class="dir">[<span class="const">VALIDATOR_DIR</span>]</span>" create a directory "<span class="dir">WEB-INF</span>", and In "<span class="dir">[<span class="const">VALIDATOR_DIR</span>]/WEB-INF</span>" create a directory "<span class="dir">lib</span>":<br />
87: <kbd>mkdir -p WEB-INF/lib</kbd>
88: </li>
1.8 ot 89: <li>Copy all the jar files (from the <a href="#prereq-libs">prerequisites</a>) to the directory "<span class="dir">[<span class="const">VALIDATOR_DIR</span>]/WEB-INF/lib</span>"</li>
90: <li>Compile the validator's source: from the directory <span class="dir">[<span class="const">VALIDATOR_DIR</span>]</span>,
91: Run <kbd>ant</kbd>, while making sure that the jar files you downloaded are correctly set in you CLASSPATH environment variable.
92: Generally, the following will just work:<br />
93: <kbd>CLASSPATH=.:./WEB-INF/lib:$CLASSPATH ant</kbd>
1.7 ot 94: </li>
1.8 ot 95: <li>Copy or move "<span class="dir">[<span class="const">VALIDATOR_DIR</span>]/</span><span class="file">css-validator.jar</span>"
96: to "<span class="dir">[<span class="const">VALIDATOR_DIR</span>]/WEB-INF/lib/</span>".</li>
1.7 ot 97: <li>
1.8 ot 98: Copy or move file "<span class="file">web.xml</span>" from
99: "<span class="dir">[<span class="const">VALIDATOR_DIR</span>]/</span>" to
100: "<span class="dir">[<span class="const">VALIDATOR_DIR</span>]/WEB-INF/</span>".
1.7 ot 101: </li>
1.8 ot 102: <li>
103: Finally, reload the Tomcat server:<br />
104: <kbd>"cd <span class="dir">[<span class="const">TOMCAT_DIR</span>]</span>; <span class="dir">./bin/</span><span class="file">shutdown.sh</span>; <span class="dir">./bin/</span><span class="file">startup.sh</span>;"</kbd>
1.7 ot 105: </li>
1.8 ot 106: </ol>
1.7 ot 107:
108: <h4>Install on Jigsaw Web Server</h4>
1.8 ot 109: <ol class="instructions">
110: <li>First, download the source as described above, get the necessary jars, and build the source with <kbd>ant</kbd>.</li>
1.7 ot 111:
112: <li>Then you have to configure the validator home directory (usually this is
113: css-validator) so that it can work as a servlet container. For this purpose
114: you need to have Jigsaw installed (see the Jigsaw pages for a short
115: instruction (it is really easy)) and then start Jigsaw Admin. Change the
116: HTTPFrame to ServletDirectoryFrame.</li>
117:
118: <li>The next step is to create a resource "validator", with as class
119: 'ServletWrapper' and as frame 'ServletWrapperFrame'. The latter should add
120: itself automagically. The class of the servlet is
121: org.w3c.css.servlet.CssValidator. If there already exists a file named
122: 'validator', please rename it. It is important that this 'alias' is always
123: named 'validator'.</li>
124:
125: <li>Finally, start jigsaw and run the validator. Check which HTML you want to
126: invoke. Usually your URL will look like this:<br />
127: http://localhost:8001/css-validator/validator.html</li>
1.8 ot 128: </ol>
1.7 ot 129:
130: <h3>Command-line usage</h3>
131:
132: <p>The CSS validator can also be used as a command-line tool, if your computer
1.8 ot 133: has java installed. build the css-validator.jar as explained above, and run as:<br />
134: <kbd>java -jar css-validator.jar http://www.w3.org/</kbd>
