UIMA : Task
Hi,
I am using the Simple-Server from the Sandbox.
When I load a text-file of size 4MB to generate the corresponding annotation-xml
then I get the following exception:
==============================================================================
org.apache.uima.simpleserver.servlet.SimpleServerServlet: POST request received:

Can you please let me know how I can resolve this error ?
Thanks in Advance,

Hi,
When you do POST, do you use "text" as the parameter for setting the string
from your input text-file ?
It will help if you can give us more info about the parameters of your POST.
