Trouble getting Javascript example to work
« on: March 22, 2011, 12:01:52 »
Hey, I created a test.html with the following code and dropped the rpc.js into the same diretory as frontPage.jsp in my brand-spanking newly updated 1.7.0 Queuemetrics:

<html>
<head>
<title>test.html</title>
<script src="rpc.js"></script>
</head>
<body>
<h1>QueueMetrics JavaScript XML-RPC example </h1>
<script>
var server = "/DAILY/xmlrpc.do";
function run() {
try {
var service = new rpc.ServiceProxy( server, {
asynchronous:false,
protocol: "XML-RPC",
methods: ["QM.stats", "QM.realtime", "QM.auth"]
} );
res = service.QM.stats( "q1", "robot", "robot","", "",
"2005-10-10.10:23:12", "2009-10-10.10:23:10","",
[ "KoDO.DiscCauses", "CallDistrDO.AnsDistrPerDay" ]
);
document.getElementById("RESULT").innerHTML = plotBlocks(res);
} catch(e) {
alert("Error raised: " + e);
}
}
function plotBlocks( hmBlocks ) {
s = "";
for (var i in hmBlocks) {
s += "<h2>Block: " + i + "</h2>";
s += plotBlock( hmBlocks );
}
return s;
}
function plotBlock( arBlock ) {
s = "";
for ( r =0; r < arBlock.length; r++ ) {
s += "<tr>";
for ( c = 0; c < arBlock[r].length; c++ ) {
s += "<td>" + arBlock[r][c] + "</td>";
}
s += "</tr>";
}
return "<table border=1>" + s + "</table>";
}
</script>
<input type="button" value="Click me!" onclick="run();" >
<div id="RESULT"></div>
</body>

</html>



and I get the following error once I click "Click me!"

Block: result

Any ideas? The only part of it I really don't understand is the 

var server = "/DAILY/xmlrpc.do"

and searching xmlrpc.do in the pdf manual for the xmlrpc interface is just references to it in other examples in the other languages, with differing syntax. Any ideas?

You need to serve the example from the same container, e.g. Tomcat, that is serving QM.

You could invoke the file as:

Code: [Select]
http://myserver:8080/jstest/mypage.html
and you could have QM available as

Code: [Select]
http://myserver:8080/queuemetrics/
In this case you would set the

Code: [Select]
var server = "/queuemetrics/xmlrpc.do";

Great. I made the appropriate changes to my test file and re-uploaded but I still receive the same message.

(edit: genuine use of the word great here. I really appreciate all the help you guys provide on here.)

Question: do you have the RPC library from Google installed?
In such cases, I suggest using TCPDUMP to see what is going on....

Yes, I have the RPC library installed. I wouldn't even know how to apply tcpdump to this issue; I am doing some reading and understand the premis but do not know how it would help me troubleshoot the error I'm getting.

Not I get this error in Firefox when trying to launch it after it hangs for 15 seconds or so:

Error raised: Error: Unable to call "QM.stats". Server responsed with error (code -1): java.lang.OutOfMemoryError: Java heap space

Yes, this is likely because you should give QM more RAM. The XML-RPC service is a bit expensive.
