DocumentBuilderFactoryImpl not found Printing Mac OS X

Question

OS - Mac OS X 10.3.6
Java - 1.4.1_01
I'm attempting to print a report generated by Jasper Reports in a Java Application. I select the print button in the frame, and the print dialog for Mac OS X appears. I select "Print" and the following exception appears in the console ...
Exception in thread "Thread-1" javax.xml.parsers.FactoryConfigurationError:
Provider org.apache.xerces.jaxp.DocumentBuilderFactoryImpl not found
        at javax.xml.parsers.DocumentBuilderFactory.newInstance(DocumentBuilderFactory.java:99)
        at net.sf.jasperreports.engine.util.JRStyledTextParser.<init>(JRStyledTextParser.java:145)

JavaAWT: Assertion failure: Java exception thrown
JavaAWT: File src/macosx/native/apple/awt/util/AWTException.m; Line 40
JavaAWT: Assertion failure: _javaException
JavaAWT: File src/macosx/native/apple/awt/util/AWTException.m; Line 48I discovered the following in the API about the FactoryConfigurationError which is seen in the stack trace..
public class FactoryConfigurationError extends Error
Thrown when a problem with configuration with the Parser Factories exists. This error will typically be thrown when the class of a parser factory specified in the system properties cannot be found or instantiated.
I have included the following in the Classpath in my Manifest:
jasperreports-0.6.2.jar itext-1.01.jar commons-logging-1.0.2.jar commons-beanutils-1.5.jar commons-digester-1.3.jar commons-collections-2.1.jar xerces.jar
And I had been using the following System property for the parser...
System.setProperty("org.xml.sax.driver", "org.apache.xerces.parsers.SAXParser");I have discovered though that Mac OS X JRE version 1.4.1 (bundled within the operating system itself) contains the Crimson implementation of JAXP 1.2. As indicated in this thread:
http://forum.java.sun.com/thread.jspa?forumID=34&messageID=2031200&threadID=448102
This may be what is causing my problem. Although the xerces jar is on the classpath, it may be that the Crimson is being used or should be used instead(?) So I tried setting the parser to use the Crimson Driver with no success..
System.setProperty("org.xml.sax.driver", "org.apache.crimson.parser.XMLReaderImpl");Also unsuccessfully I tried explicitly setting the System property for the DocumentBuilderFactory as suggested here:
http://developer.apple.com/documentation/WebObjects/XML_Serialization/Transformation/chapter_5_section_4.html
System.setProperty("javax.xml.parsers.DocumentBuilderFactory",
"org.apache.crimson.jaxp.DocumentBuilderFactoryImpl");But the same exception as previously posted is thrown.
I have no troubles printing reports in the same manner on Windows or Linux. Usuing the same Manifest, classpath, jar files etc..I have only seen the error on Mac OS X. Any help would be appreciated. Thanks so much.

I agree with your observation: removing xerces.jar from the classpath fixes the printing problem, but the XML parsing speed is something like 4-5 times slower (1.4.2_05, 10.3.7, PowerBook 1.5GHz, 1Gb) with the default XML parser than using Apache DOMParser explicitely... my application can print, but the rest of the XML manipulations is terribly slower. Great! : (
