   I am trying to include some visualizations I created using Processing into my posts. Processing exports the visualisation as a java-object and also generates some code you can use to include the java-object on a webpage (see below for an example of the code generated by Processing). However, I have trouble including this code in WordPress.

   I switched to the HTML-editor instead of the visual editor. Removing all of the linebreaks in the code helped as WordPress stopped inserting <br /> into the code. However, WordPress still causes problems with the comments as the --'s are replaced by m/ndashes.

   So how do I include this code? I would have expected this question to have been asked before, by I could not find it in the archives. Help is appreciated.

   The html-code generated by Processing:

   <!--[if !IE]> -->
     <object classid="java:test.class" type="application/x-java-applet"
         archive="test.jar" width="700" height="800"
         standby="Loading Processing software..." >
       <param name="archive" value="test.jar" />
       <param name="mayscript" value="true" />
       <param name="scriptable" value="true" />
       <param name="image" value="loading.gif" />
       <param name="boxmessage" value="Loading Processing software..." />
       <param name="boxbgcolor" value="#FFFFFF" />
       <param name="test_string" value="outer" />
   <!--<![endif]-->
     <object classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"

       <param name="boxmessage" value="Loading Processing software..." />
       <param name="boxbgcolor" value="#FFFFFF" />
       <param name="test_string" value="inner" />

   OK I have solved the problem by using Shortcode.

   I created the following functions.php in my theme directory:

   <?php
     function processing_object($atts, $content = null) {
       extract(shortcode_atts(array('jar' => '', 'class' => '',
           'width' => 700, 'height' => '800'), $atts));
       if ($jar == '' || $class == '') return '<p>Syntax error</p>';
       $result = <<<EOD
   <div id="processing_container">
     <!--[if !IE]> -->
       <object classid="java:$class.class"
           type="application/x-java-applet"
           archive="$jar"
           width="$width" height="$height"
           standby="Loading Processing software..." >
         <param name="archive" value="$jar" />
         <param name="mayscript" value="true" />
         <param name="scriptable" value="true" />
         <param name="image" value="loading.gif" />
         <param name="boxmessage" value="Loading Processing software..." />
         <param name="boxbgcolor" value="#FFFFFF" />
         <param name="test_string" value="outer" />
     <!--<![endif]-->
       <object classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
           codebase="http://java.sun.com/update/1.5.0/jinstall-1_5_0_15-windows-i586.cab"
           width="$width" height="$height"
           standby="Loading Processing software..."  >
         <param name="code" value="$class" />
         <param name="archive" value="$jar" />
         <param name="mayscript" value="true" />
         <param name="scriptable" value="true" />
         <param name="image" value="loading.gif" />
         <param name="boxmessage" value="Loading Processing software..." />
         <param name="boxbgcolor" value="#FFFFFF" />
         <param name="test_string" value="inner" />
         <p><strong>This browser does not have a Java Plug-in.<br />
           <a href="http://www.java.com/getjava" title="Download Java Plug-in">Get the latest Java Plug-in here.</a></strong>
         </p>
       </object>
     <!--[if !IE]> -->
       </object>
     <!--<![endif]-->
   </div>
   EOD;
       return $result;
     }
   
     add_shortcode('processing', 'processing_object');
   ?>

   And could then include the java object by using

   [processing jar="test.jar" class="test"]

   in my post.

   Thanks - worked like a charm. Lifesaver.
   Possibly make this a plugin -- This will break when I switch to a different theme, right?
