A validator is a thread-unsafe and non-reentrant object.
In other words, it is the application's responsibility to make
sure that one <A HREF="../../../javax/xml/validation/Validator.html" title="class in javax.xml.validation"><CODE>Validator</CODE></A> object is not used from
more than one thread at any given time, and while the <tt>validate</tt>
method is invoked, applications may not recursively call
the <tt>validate</tt> method.
<p>
Note that while the <A HREF="../../../javax/xml/validation/Validator.html#validate(javax.xml.transform.Source)"><CODE>validate(javax.xml.transform.Source)</CODE></A> and <A HREF="../../../javax/xml/validation/Validator.html#validate(javax.xml.transform.Source, javax.xml.transform.Result)"><CODE>validate(javax.xml.transform.Source, javax.xml.transform.Result)</CODE></A>

public abstract void <B>setErrorHandler</B>(org.xml.sax.ErrorHandler errorHandler)</PRE>
<DL>
<DD>Sets the <CODE>ErrorHandler</CODE> to receive errors encountered
during the <code>validate</code> method invocation.
<p>
Error handler can be used to customize the error handling process
during a validation. When an <CODE>ErrorHandler</CODE> is set,
errors found during the validation will be first sent
to the <CODE>ErrorHandler</CODE>.
<p>
The error handler can abort further validation immediately
by throwing <CODE>SAXException</CODE> from the handler. Or for example
it can print an error to the screen and try to continue the
validation by returning normally from the <CODE>ErrorHandler</CODE>
<p>
If any <CODE>Throwable</CODE> is thrown from an <CODE>ErrorHandler</CODE>,
the caller of the <code>validate</code> method will be thrown
the same <CODE>Throwable</CODE> object.
<p>
<A HREF="../../../javax/xml/validation/Validator.html" title="class in javax.xml.validation"><CODE>Validator</CODE></A> is not allowed to
throw <CODE>SAXException</CODE> without first reporting it to
<CODE>ErrorHandler</CODE>.
<p>
When the <CODE>ErrorHandler</CODE> is null, the implementation will
behave as if the following <CODE>ErrorHandler</CODE> is set:
<pre>
class DraconianErrorHandler implements <CODE>ErrorHandler</CODE> {
public void fatalError( <CODE>SAXParseException</CODE> e ) throws <CODE>SAXException</CODE> {

<DL>
<DD>Sets the <CODE>LSResourceResolver</CODE> to customize
resource resolution while in a validation episode.
<p>
<A HREF="../../../javax/xml/validation/Validator.html" title="class in javax.xml.validation"><CODE>Validator</CODE></A> uses a <CODE>LSResourceResolver</CODE>
when it needs to locate external resources while a validation,
although exactly what constitutes "locating external resources" is
up to each schema language.
<p>
When the <CODE>LSResourceResolver</CODE> is null, the implementation will
behave as if the following <CODE>LSResourceResolver</CODE> is set:
<pre>

public <CODE>LSInput</CODE> resolveResource(
String publicId, String systemId, String baseURI) {

(or instances of its derived classes),
then the <A HREF="../../../javax/xml/validation/Validator.html" title="class in javax.xml.validation"><CODE>Validator</CODE></A> will abort the parsing and
