我需要在不使用visual studio创建的webreference的情况下调用Web服务，我必须使用 http web请求我有肥皂请求：
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:pos="http://posting.ws.rpg.snamretegas.it/">
<soapenv:Header/>
<soapenv:Body>
<pos:postAllReports>
<report_name>REPORT_SWITCH</report_name>
<report_date></report_date>
<i_ambiente>ITG1</i_ambiente>
<i_taxidOpco>TEST_YF1</i_taxidOpco>
</pos:postAllReports>
</soapenv:Body>
</soapenv:Envelope>
这是asp页面背后的代码：

请你能告诉我为什么不打电话给Ws ???
请问我怎么调试这个？你在代码中看到了什么问题吗？
我也对异步模式感到疯狂
最后是asp页面：

答案 0 :(得分：0)
确定在java中有一个外部客户端，我确实生成了一个调用webservice的jar 在我这样做之后，在aspx页面中调用webserice：
System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.StartInfo.RedirectStandardOutput = true;
proc.StartInfo.RedirectStandardError = true;
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.FileName = "\"" + System.Web.HttpContext.Current.Server.MapPath(".") + "\\" + "ConsoleApp.jar" + "\"" ;
if(datarepo != "")
proc.StartInfo.Arguments = "\""+connectionString +"\"" + " " +"\"" +reportname+"\"" + " " +"\"" +datarepo+"\"" + " " +"\"" +opco+"\"" + " " + "\"" +ambienteParm+"\"";
else
proc.StartInfo.Arguments = "\""+connectionString +"\"" + " " +"\"" +reportname+"\"" + " " +"\"" + "\"" + " " +"\"" +opco+"\"" + " " + "\"" +ambienteParm+"\"";
proc.Start();
proc.WaitForExit();
//string result = proc.StandardOutput.ReadToEnd();
//Response.Write(result + " - " + proc.ExitCode);
proc.Close();
对所有人来说。
