Hi,
I have a gwt based application,that uses RPC calls to communicate with
the server. Normally this works fine, however occasionally the
response fails and I'm unsure what is causing it. Using firebug, I can
see the response is garbled text instead of the OK message. An example
of the response is below:
f8
� ��������PKk�0 �/9�`�G �>�0rXYz ] ����Q�f�~N�8
V���IH� �77��� k�" ~�� I4�*3�� �,��A1�e_<��-� ��*�vچ�xi�th�r +�'8F �C
$�+��q��<to ]�OP ����U��ڠ�2ş,
>�xJ� �'������F�˛7q�O��6�̵�J �h/�����㍕�
ռ������j��y Vb���O�^g��"� ��� + -5��� ��

The server logs seem to show the server impl processing was completed
sucessfully, but the localhost log shows the following stack trace:
12-Mar-2009 08:52:13 org.apache.catalina.core.StandardWrapperValve

At present I am still using gwt1.4, the inention is to upgrade to 1.5
shortly, and it's running against a tomcat 6 server.
Is there anything obvious that I need to do to avoid these sorts of
error, or methods to debug what has gone wrong between me completing
the impl code processing and recieving the response on the client?
Thanks.
