post of large xml file on third party webservices

i want to post large xml file on third party web services through httpclient but failed to do so... but i m successfully post the xml file containing less data is there any way to post large xml file

What error do you get?

my code client.executeMethod(request); does't run

i am nt able to post large xml file i don't know why bcoz it does't give any error

It must be doing something.
Have you debugged through it?

Is it hanging?

yes sir it is hanging

Then it could be that the third party service is having problems with the large file.
