First, Thank yo very much for your Reply.

I read the Documentation of HTTPConnection and I think I can use it but the Web Services I call base upon XML, so I have to write my own parser and that's the point I want to avoid.

The advantage of kSoap is that it has a parser for the Replies of the Web Services that I can use.

I will try out the jar file of the Link you posed an I hope it will be helpfull.
