java.lang.NoClassDefFoundError Exception in java

I am generating java classes from xsd using JAXB 1.0 (JDK 1.5 and Java Web Service Developer Pack 1.5). It is working fine in local. When, I tried in server, I am getting the following exception.

ErrMsg=[Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/xml/bind/unmarshaller/InterningXMLReader at
