Hi adam,
i feel happy if u give the steps to fallow. how to develop
UIMA as web application.
i will explain u till now what i have done.
1) have written on servlet with name test.java,
2)i have written one more class with main method
3)i put descriptors like aedescriptor.xml,type,input and out put under web
root and also in tomact folder.
i have run that project in eclipse console i got the result which is
raeding from the c:/tomacta/descriptor.
once this is over i opend IEBrowser given urlpattern here i got that error
which is there in previous reply.i will add my code it.plz don't mind
i hope u will get my point what i am trying to say
i was stuck up here
