Calling a Specific Web Service Method Using Javascript or jQuery
Question
I've successfully invoked a web service when loading a jsp page. The issue I'm facing is setting up a user to be able to press a button to invoke a different method on that same web service. The function "getSS()" is supposed to accomplish this, but I suppose that javascript doesn't directly read that type of invocation. I've found solutions that call up the web service and pass a parameter to it, but those are usually not calling up specific methods within the webservice.
Here is my code, what can I put in the "getSS()" function to accomplish this? I've already loaded jQuery, and the web service is written in java. Note, I already wrote the code to do all the work, I just need to know how to call that specific code. None of the other solutions seem to fit my needs.

So it seemed all I was missing was setting that java code to a variable and putting the proper opening and closing statements:
function doIt(){
<%-- start web service invocation --%>
var x = <%
try {
org.me.testbilling.TestBillingWS_Service service = new org.me.testbilling.TestBillingWS_Service();
org.me.testbilling.TestBillingWS port = service.getTestBillingWSPort();
// TODO initialize WS operation arguments here
java.lang.String name = "Marcel" ;
// TODO process result here
java.lang.String result = port.getSS(name);
out.println(result);
} catch (Exception ex) {
// TODO handle custom exceptions here
}
%>
<%-- end web service invocation --%>
alert(x);
}
</script>
Still not quite sure how to make that "java.lang.String name =" be set to a javascript variable.
