<p class=MsoNormal>Hi everybody.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I am currently trying to upgrade an old app from JBoss 3.2.5
to the latest version in the hope of breathing some new life into it.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have made a number of changes suggested by the upgrade guide
(changing my Datasource config etc.), however when I deploy my app am am
getting some errors related apparently to xerces.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I get this error if I try and deploy one web-app.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>14:30:08,354 ERROR [Digester] Digester.getParser:<o:p></o:p></p>
<p class=MsoNormal>java.lang.ClassCastException:
org.apache.xerces.jaxp.SAXParserFactoryImpl<o:p></o:p></p>

javax.xml.parsers.SAXParserFactory.newInstance(Unknown Source)<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I get this error when I try and access the other web-app
(which seems to deploy ok). I have checked the org.apache.xerces.parsers.SAXParser
class I am using and it definitely implements XMLReader).<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>org.jdom.JDOMException: Could not load default SAX parser:
org.apache.xerces.parsers.SAXParser: SAX2 driver class
org.apache.xerces.parsers.SAXParser does not implement XMLReader<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I also have an ear which seems to deploy ok.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I am using JBoss 4.0.5 and have recompiled everything
against the xercesimpl.jar and xml-api.jar files found in JBoss’s
lib/endorsed folder. There are no other versions of xerces in any of my ears or
wars – just that version. My initial research leads me to believe this is
a class-loading issue and that maybe my default sax parser is incorrect?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Anybody got any ideas?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks for your time.<o:p></o:p></p>
