//This is my server side code in java web services
public class Demoapp {

//web method getname
public String getname(){
String s="HI this is First";

return s;
}

}

//This was my client side code using javascript
var settings = {requestType:"soap1.1",
error:function(XMLHttpRequest, textStatus, errorThrown){
throw XMLHttpRequest.responseText;
}};
var oBuffer = new Array();
settings.requestType = "soap1.1";
settings.methodType = "POST";
settings.contentType = "text/xml";
settings.url = "http://192.168.1.5:8080/Demoweb/services/Demoapp?wsdl";
settings.dataType = "text/xml";
settings.nameSpace = "http://Demoweb/";
settings.methodName = "getname";

oBuffer.push('<soap:envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">');

I would suggest you to update your question to include this code and also tag Java to your question so others can take a look at it. I am not an expert in Java so i may not be able to give the correct solution.
