Error while converting XSD using Jar

I'm trying to convert a XSD using Jar and a batch file which sets the classpath and other relevant paramters. I get the Error:
Exception in thread "main" java.lang.NoClassDefFoundError: org/xml/sax/ErrorHandler

The classpath has the following jar files:

xercesImpl-1.5.jar

sax2.jar

sax-2.0.1.jar

dom.jar

dom4j-1.6.1.jar

xalan.jar

xsdlib.jar

jaxb-api.jar

jaxb-impl.jar

jaxb-libs.jar

jaxb-xjc.jar

namespace.jar

jax-qname.jar

relaxngDatatype.jar

Although the class org/xml/sax/ErrorHandler exists in the jar sax.jar but still this error comes up.
Kindly Help

That must be your problem then... you don't have "sax.jar" in your classpath. Not if your classpath is the list of jars you posted, anyway.

How's the classpath being set? care to share batch file snippet?

Trilochan.

Thanks! I was able to resolve the issue. The only problem was the JDK being used. Changed the path to take jdk1.4 and the issue was resolved
