Two common causes:
1) You didn't register a deserializer for the class. WSDL2Java can generate the
deploy.wsdd which matches the type to the Java class that deserializes it.
2) Name spaces are case sensitive. So, though in DNS space MyFakeDomain.com and
myfakedomain.com are the same, to SAX they are different namespaces. The first
thing to check is if the WSDL of the service you are calling matches the WSDL
you might have generated your stubs from, letter for letter matching case. Last
time I ran into this error, that was the cause. -- Andy

Hi,
I just started to use Axis, and I stopped on error like in this post
topic - full output which I get from Servlet is:
org.xml.sax.SAXException: No deserializer for

What is wrong with this deserializer error? I provide some other files
below, but maybe there is any common reason for such error? Please,
can anyone give me the link to the simplest tutorial on using complex
types, or tell me which Axis samples consider complex types and is in
other hand the easiest to learn (I need to solve it very quickly to
show Axis my boss, as a potential WS platform :).
tcpmon output shows that there is an answer from service as:

File Statistics.jws looks like:

public class Statistics {
// ... some other methods to initialize DB
public TailRecord[] tail(){

try {
