xmlrpc to old?

Hi there, I am building a webservice for the first time with php. No I have worked with xmlrpc and it is almost finished. After moving the service to another server with different display error settings I am getting loads of debrecated warnings. I went to the sourceforge site and found a newer version, but seems to be completly incompatible with the "old" one. Plus it seems that the project is frozen and no further development is made. Can anybody suggest what to do? Stick with xmlrpc and convert my application to the new neds of xmlrpc or switch to someting else, in this case to what?. Thanx for any help, links and any info you can give me on that. Merlin
