<h2 id="what-is-currently-supported-and-what-is-not">What is currently supported and what is not</h2>
|
|
|
|
<p>In short, JSP files that are XHTML-compliant, are supported.
|
|
Except for files that contain inline DTDs; only references to external
|
|
DTD files are supported (having inline DTD will result in a parsing
|
|
error).</p>
|
|
|
|
<p>The XHTML support means that:</p>
|
|
|
|
<ul>
|
|
<li>
|
|
<p>opening tags must be accompanied by corresponding <em>closing tags</em>
|
|
(or they must be empty tags). This means that currently a “<HR>”
|
|
tag without corresponding closing tag will result in a parsing error.</p>
|
|
</li>
|
|
<li>
|
|
<p><em>attribute values</em> must be <em>surrounded by</em> single or double <em>quotes</em>. This means that the following syntax
|
|
will result in a parsing error:</p>
|
|
|
|
<p><MyTag myAttr1=true myAttr2=1024/></p>
|
|
</li>
|
|
<li>
|
|
<p>< and > characters must be <em>escaped</em>, or put inside a CDATA section.</p>
|
|
|
|
<p>PMD creates a “Abstract Syntax Tree” representation of source code; the rules use such a tree as input.
|
|
For JSP files, the following constructs are parsed into nodes of the tree:</p>
|
|
|
|
<ul>
|
|
<li>XML-elements, XML-attributes, XML-comments, doctype-declarations, CDATA</li>
|
|
<li>JSP-directives, JSP-declarations, JSP-comments, JSP-scriptlets, JSP-expressions,
|
|
Expression Language expressions, JSF value bindings</li>
|
|
<li>everything else is seen as flat text nodes.</li>
|
|
</ul>
|
|
</li>
|
|
<li>
|
|
<p>Java code (e.g. in JSP-scriptlets) and EL expressions are not parsed or
|
|
further broken down. If you want to create rules that check the code
|
|
inside EL expressions or JSP scriptlets (a.o.), you currently would
|
|
have to do “manual” string manipulation (e.g. using regular expressions).</p>
|
|
</li>
|
|
</ul>
|
|
|
|
<h2 id="how-to-use-it">How to use it</h2>
|
|
|
|
<p>Using the command-line interface, two new options can be used in the arguments string:</p>
|
|
|
|
<ul>
|
|
<li>“-jsp” : this triggers checking JSP files (they are not checked by default)</li>
|
|
<li>“-nojava” : this tells PMD not to check java source files (they are checked by default)</li>
|
|
</ul>
|
|
|
|
<p>Using the Ant task, you decide if PMD must check JSP files by choosing
|
|
what files are given to the PMD task. If you use a fileset that
|
|
contains only “.java” files, JSP files obviously will not be checked.</p>
|
|
|
|
<p>If you want to call the PMD API for checking JSP files, you should investigate the javadoc of PMD.</p>
