I've writen two clients to access Google and Amazon Web APIs, After recieving
the Response I get the following Exception.
-------------------------------------------------------------------------------------------------------------------------
Key: AXIS2-23
URL: http://issues.apache.org/jira/browse/AXIS2-23
Project: Axis2
Type: Bug
Components: om
Environment: Windows XP sp1,
Reporter: L.P.Gayan Asanka
Assigned to: Davanum Srinivas
Hi All,
I have built a programs to access Google Web API and Amazon Web API via AXIS2.
The operation is ‘doGoogleSearch’ in Google WSDL and ‘search’ in Amazon
WSDL, I can set the number of search results that should be included in the
response message. In Google When the number of results is 1 or 2 it is working
almost properly, But when the number of results are getting higher (that means
the SOAP msg is big) I am getting an exception. When the results count is 10,
most probably this exception is thrown. In the case of Amazon, the exception is
always thrown. This programs worked with M1 successfully.
I guess the problem is with OM and Stax, I hope your aid to solve this problem.
Exception thrown is:-
