The code I am using is as following: xmlhttp.open("POST","/ws/WebService1.asmx/RunSolution",false); xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded"); sParameters = "SolutionName=" + SolutionName; xmlhttp.send(sParameters); xmlDoc=xmlhttp.responseXML; After xmlhttp.send the xmlhttp status is 500. I checked the event log on the server: Exception information: Exception type: InvalidOperationException Exception message: Request format is unrecognized for URL unexpectedly ending in '/RunSolution'. Request information: Request URL: http://virtualxp-55370/ws/Service1.asmx/RunSolution Request path: /ws/Service1.asmx/RunSolution User host address: 10.194.3.181 User: Is authenticated: False Authentication Type: Thread account name: VIRTUALXP-55370\ASPNET Thread information: Thread ID: 1 Thread account name: VIRTUALXP-55370\ASPNET Is impersonating: False And in the web.config file, HttpGet and HttpPost have been added for webServices. Thanks in advance. Monday, May 16, 2011 1:10 PM All replies 0 Sign in to vote What does the web.config say in the "protocols" section?John Saunders WCF is Web Services. They are not two separate things. Use WCF for All New Web Service Development, instead of legacy ASMX or obsolete WSE Use File->New Project to create Web Service Projects Monday, May 16, 2011 7:27 PM Moderator 0 Sign in to vote Thanks John, The issue has been resolved. It is because the client used a wrong web.config file in which httpGet and httpPost were not enabled. Friday, May 20, 2011 1:24
