    java.lang.ClassCastException: org.apache.xerces.jaxp.SAXPars

      Hi,

      I use a JBOSS 4.04 (Seam + JSF/Facelet) with a JVM Sun 1.5.09.

      One service must convert HTML to PDF. For this task, IText v.1.4.7 (http://www.lowagie.com/iText/) library is employed.

      But IText requires a SAX parser factory and when I'm calling action, I obtain the next exception :

      16:24:59,765 ERROR [STDERR] Error while converting document. Message: org.apache.xerces.jaxp.SAXParserFactoryImpl
16:24:59,765 ERROR [STDERR] java.lang.ClassCastException: org.apache.xerces.jaxp.SAXParserFactoryImpl
16:24:59,765 ERROR [STDERR] at javax.xml.parsers.SAXParserFactory.newInstance(Unknown Source)


      In my classpath : 

      commons-beanutils-1.7.0.jar
commons-codec-1.3.jar
commons-digester-1.6.jar
emma_ant.jar
emma.jar

itext-1.4.7.jar
Tidy.jar
thirdparty-all.jar

      EAR hierarchy : 

      EAR
 + itext-1.4.7.jar
 + jboss-seam.jar
 + jbpm-3.1.1.jar
 + Tidy.jar
 + application.jar
 + application.ear


      Partial code of service : 
       try {
 SAXParserFactory factory = SAXParserFactory.newInstance();
 SAXParser saxParser = factory.newSAXParser();

 if (saxParser != null) {
 Document document = new Document(PageSize.A4);
 PdfWriter.getInstance(document, out);
 }
 }
 catch (ParserConfigurationException e)
 {
 System.err.println("[ParserConfigurationException] Error while converting document. Message: " + e.getMessage());
 }
 catch (Exception e) {
 System.err.println("Error while converting document. Message: " + e.getMessage());
 e.printStackTrace();
 }


      Exist there a configuration handling to solve this problem ?

      Thank you for your help.

          Sorry, there are some errors :

          for the EAR :

          + itext-1.4.7.jar
 + jboss-seam.jar
 + jbpm-3.1.1.jar
 + Tidy.jar
 + application.jar
 + application.war


          and I forget application.xml file : 

          <application xmlns="http://java.sun.com/xml/ns/j2ee" version="1.4"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

          Erratum : the classpath is Eclipse classpath.

          Thank you.
