I am developing a Java client application, using classes auto-generated by WSDL2Java, that makes requests to a Perl web service. All of the service requests work fine unless the service returns a SOAP fault. In all cases, the fault causes the following error on the client:
[DEBUG][org.apache.axis.transport.http.HTTPSender]: org.xml.sax.SAXParseException: Comment must start with "<!--".
Looking at the log, this error appears immediately after:
[DEBUG][org.apache.axis.encoding.DeserializationContext]: Enter: DeserializationContext::endPrefixMapping(soapenv)
[DEBUG][org.apache.axis.encoding.DeserializationContext]: Exit: DeserializationContext::endPrefixMapping()
Here is the actual soap fault returned from the Perl web service:
500 (Internal Server Error)
Content-Length: 532
Content-Type: text/xml
SOAPServer: SOAP::Lite/Perl/0.600.0
<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenc="http://schemas.xmlsoaporg/soap/encoding/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
soapenv:encodingStyle="http://schemas.xmlsoaporg/soap/encoding/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:soapenv="http://schemas.xmlsoaporg/soap/envelope/">
<soapenv:Body>
<soapenv:Fault>
<faultcode>soapenv:Server</faultcode>
<faultstring>Error getting guest information from property system</faultstring>
</soapenv:Fault>
</soapenv:Body>
</soapenv:Envelope>
Unfortunately, I have not been able to reproduce this issue in an isolated case. Parsing the above xml through the SAXParser class in a simple test application is successful. I am completely stumped, and I've found no trace of documentation about this issue anywhere. Any help you can provide would be greatly appreciated.
Here is the stack trace at the point of the error, if it is helpful in any way:
