            <question>Why do I get warnings when using a JAXP 1.1 parser?
                <p>If you're using a JAXP 1.1 parser, you might see the following warning (in your log):

<source> [WARN] Digester - -Error: JAXP SAXParser property not recognized: http://java.sun.com/xml/jaxp/properties/schemaLanguage </source> <p>This property is needed for JAXP 1.2 (XML Schema support) as required for the Servlet Spec. 2.4 but is not recognized by JAXP 1.1 parsers. This warning is harmless.</p> </answer> </faq> <faq id="schema_validation_out_box"> <question>Why Doesn't Schema Validation Work With Parser XXX Out Of The Box? <answer>

Schema location and language settings are often need for validation using schemas. Unfortunately, there isn't a single standard approach to how these properties are configured on a parser. Digester tries to guess the parser being used and configure it appropriately but it's not infallible. You might need to grab an instance, configure it and pass it to Digester. </p> <p> If you want to support more than one parser in a portable manner, then you'll probably want to take a look at the <code>org.apache.commons.digester.parsers package and add a new class to support the particular parser that's causing problems. </p> </faq> <faq id="help"> <question>Help! I'm Validating Against Schema But Digester Ignores Errors!</question> <answer>

Digester is based on <a href="http://www.saxproject.org">SAX. The convention for SAX parsers is that all errors are reported (to any registered <code>ErrorHandler) but processing continues. Digester (by default) registers its own <code>ErrorHandler implementation. This logs details but does not stop the processing (following the usual convention for SAX based processors). </p> <p> This means that the errors reported by the validation of the schema will appear in the Digester logs but the processing will continue. To change this behaviour, call <code>digester.setErrorHandler with a more suitable implementation. </p> </faq> <faq id="example_code"> <question>Where Can I Find Example Code? <answer>

Digester ships with a sample application: a mapping for the Rich Site Summary</em> format used by many newsfeeds. Download the source distribution to see how it works.</p> <p>Digester also ships with a set of examples demonstrating most of the features described in this document. See the "src/examples" subdirectory of the source distribution.</p> </faq> <faq id="support_rich_site"> <question>When Are You Going To Support Rich Site Summary Version x.y.z? <answer>

The Rich Site Summary application is intended to be a sample application. It works but we have no plans to add support for other versions of the format. </p> <p> We would consider donations of standard digester applications but it's unlikely that these would ever be shipped with the base digester distribution. If you want to discuss this, please post to <a href="http://commons.apache.org/mail-lists.html"> commons dev mailing list</a> </p> </faq> </part> </faqs>
