[JSPWiki] Sweet Java/HTML/XML syntax coloring

I found a very nice plugin for JSPWiki this morning: the Java to HTML converter.

: This tool converts Java source code (files and snipplets) to HTML, RTF, TeX and XHTML with syntax highlighting. It is Open source under the GPL.

I've found that it works for Java, XML and HTML. Here's a couple of examples (I've hooked it into Roller's JSPWiki support):

Java


/**

* @return Returns the id.

* @hibernate.id column="id"

*  generator-class="native" unsaved-value="null"

*/



public Long getId() {

    return this.id;

}

HTML


<html>

  <head>

    <title>HTML Test</title>

  </head>

  <body></body>

</html>

XML




<?xml version="1.0"?>



<!DOCENGINE hibernate-mapping PUBLIC

    "-//Hibernate/Hibernate Mapping DTD 2.0//EN" 

    "http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd">



<hibernate-mapping>

    <class

        name="org.appfuse.persistence.User"

        table="app_user">



        <id

            name="id"

            column="id"

            type="java.lang.Long"

            unsaved-value="null"

        >

            <generator class="native">

            </generator>

        </id>



    </class>



</hibernate-mapping>

The one thing I don't like is that it centers the code using <center>, adding "center table {width: 100%}" to your stylesheet fixes the issue. I also tried to upgrade Roller's JSPWiki.jar to 2.1.86-alpha (to get XHTML support), but I was getting all kinds of stacktraces from OSCache and it just didn't work. Java2Html also has an Ant Task to convert Java source to HTML. Java2HTML has the same thing, but this new one supports different styles.

NOTE: The above syntax coloring produces invalid XHTML, so this site won't validate for awhile.

/* for the java2html plugin - so everything is not centered */ center table { width: 100%; border: 1px solid #c0c0c0; } center table td { padding: 10px; padding-bottom: 0; } center table code {position: relative; top: -10px}

Comments:

I tried this out too recently and found the same problem with the center tag. Thanks for the tip on how to effectively get rid of that - Cheers Simon.

I have released a new Version 3.5 on my website, that does no longer require the fix for the center tag. Also its output should now be XHTML compliant.

Very nice Markus! I dig that it validates now too. Thanks. ;-)

Markus, I like that you've switched from using a <center> tag to <div align="left"> - however, it was easier to write CSS when the <center> tag existed. Here's what I used in 3.4:

With 3.5, I can do the same thing with the following:

div table {
    width: 100%; 
    border: 1px solid #c0c0c0;
}

div table td {
    padding: 10px;
    padding-bottom: 0;
}

div table code {position: relative; top: -10px}

But any <table>'s inside of <div&gt's will get this rule applied to it. Would it be possible to put a class on the java2html <div>? For example <div align="left" class="java">. Just a suggestion, luckily, I don't have any table's in my div's and my altered CSS above works fine with 3.5.
