I tried to call in PHP a SOAP webservice implemented in .Net using severals "extensions" like ws-security and ws-addressing. I used wsf/php (wso2), based on rampart and axis2, and I did not succed. We asked another dev team which had developped these SOAP servers (in .Net), and they had failed too. WSO2 seems to be unachieved, bugged, and not maintened. The last problem is a buffer overflow with key greater than 1024 bytes, but there were a bunch of problems before.
Who have implemented servers or clients using ws-*? With which libs and difficulties?
