Help on ---------> comons apache XML Digester along with weblogic

[Ma...@lntinfotech.com]

Hi All,

      I am reposting the same question, can any one help me out on this...

      I am using commons-digester1.5 , I am digesting a xml file using xml
rules. When I run the Parsing in a stand alone mode it works fine. But when
the same parser is used along with Weblogic I am getting following error


org.apache.commons.digester.xmlrules.XmlLoadException: Error at (3, 142:

=============================================================================
The Source code is

strRuleFileName = "LockBoxRules.xml";
strMsgTypeFileName ="lockbox.xml";

//Read URL String from config.
URL ruleURL = RuleReader.class
.getClassLoader().getResource(strRuleFileName);
Digester digester = DigesterLoader.createDigester(ruleURL);

inputStream = RuleReader.class
.getClassLoader().getResourceAsStream(strMsgTypeFileName);
boxSummaryRuleDVO = (LockBoxSummaryRuleDVO)digester.parse(inputStream);

===================================================================

I have also attached the XML file and the XML rule file used to digest the
XML



When digged more into the Digester class, I could find out exception thrown
from the  parse(Reader reader) method. The exception is
NullpointerException( SAXParserException) because of
com.sun.jdi.ClassNotPreparedException occurred while performing method
lookup for selector "toString" with signature "()Ljava/lang/String;"
