help with Exception

["Mantri, Mr. Ramesh" <ma...@nrlmry.navy.mil>]

All,
   has anyone encountered the following Exception? What is the fix?

Jul 30, 2003 8:18:05 PM com.sun.xml.messaging.saaj.soap.MessageImpl identifyContentType
SEVERE: SAAJ0537: Invalid Content-Type. Could be an error message instead of a SOAP message
com.sun.xml.messaging.saaj.SOAPExceptionImpl: 
Invalid Content-Type:text/html. Is this an error message instead of a SOAP response?

This appears to be a transient error and I have observed this only in connection with the SOAPConnection.
The failure occurs either prior to establishing the connection (I have seen entry in apache access logs) or
prior to returning results. We run the same server on 2 different configurations - Tomcat Standalone and
Apache-Tomcat. I noticed the following error too in Apache error log:

However, I can't present any evidence regarding the failure during response. Appreciate any help.
