Error While Invoking Service Over UDP
Hi Devs,
I'm trying to invoke a simple web service over UDP. I have properly
configured and exposed my service (SimpleStockQuoteService in Synapse) over
UDP transport and I use the following client to invoke the service:
public static void main(String[] args) throws Exception {
String request =
"<m0:getQuote xmlns:m0=\"http://services.samples\">" +
"<m0:request>" +
"<m0:symbol>IBM</m0:symbol>" +
"</m0:request>" +
"</m0:getQuote>";
ConfigurationContext cfgCtx =
ConfigurationContextFactory.createConfigurationContextFromFileSystem(
CLIENT_HOME + "/client_repo",
CLIENT_HOME + "/client_repo/conf/axis2.xml");
ServiceClient client = new ServiceClient(cfgCtx, null);
client.engageModule("addressing");
Options options = new Options();
options.setTo(new
EndpointReference("udp://localhost:9999/services/SimpleStockQuoteService?contentType=text/xml"));
options.setAction("urn:getQuote");
client.setOptions(options);
OMElement res = client.sendReceive(AXIOMUtil.stringToOM(request));
System.out.println(res); // ***************************************
client.cleanup();
System.out.println("VALUE: " + parseStandardQuoteResponse(res));
}
public static String parseStandardQuoteResponse(OMElement result) throws
Exception {
AXIOMXPath xPath = new AXIOMXPath("//ns:last");
xPath.addNamespace("ns","http://services.samples/xsd");
OMElement last = (OMElement) xPath.selectSingleNode(result);
if (last != null) {
return last.getText();
} else {
throw new Exception("Unexpected response : " + result);
}
}
I can see the client is receiving the correct response. The print statement
(marked with ********) gets executed and it prints the response payload as
expected:
<ns:getQuoteResponse xmlns:ns="http://services.samples"><ns:return
xmlns:ax21="http://services.samples/xsd" xmlns:xsi="

But then the parseStandardQuoteResponse method fails with the following

The same exact code works fine with the HTTP transport. So I guess this has
something to do with the UDP transport. Any ideas?
Thanks,

Nonsense, this was just a bug in the UDP transport. See r947440.

if instance declaration is

then the declaration for xsi:type="ax21:GetQuoteResponse"
which assumes your type must be a qname (does this definition exist?)

Subject: Error While Invoking Service Over UDP
From: hiranya911@gmail.com
To: java-dev@axis.apache.org
Hi Devs,
I'm trying to invoke a simple web service over UDP. I have properly configured and exposed my service (SimpleStockQuoteService in Synapse) over UDP transport and I use the following client to invoke the service:
public static void main(String[] args) throws Exception {
String request =
"<m0:getQuote xmlns:m0=\"http://services.samples\">" +
"<m0:request>" +
"<m0:symbol>IBM</m0:symbol>" +
"</m0:request>" +
"</m0:getQuote>";
ConfigurationContext cfgCtx =
ConfigurationContextFactory.createConfigurationContextFromFileSystem(
CLIENT_HOME + "/client_repo",
CLIENT_HOME + "/client_repo/conf/axis2.xml");
ServiceClient client = new ServiceClient(cfgCtx, null);
client.engageModule("addressing");
Options options = new Options();
options.setTo(new EndpointReference("udp://localhost:9999/services/SimpleStockQuoteService?contentType=text/xml"));
options.setAction("urn:getQuote");
client.setOptions(options);
OMElement res = client.sendReceive(AXIOMUtil.stringToOM(request));
System.out.println(res); // ***************************************
client.cleanup();
System.out.println("VALUE: " + parseStandardQuoteResponse(res));
}
public static String parseStandardQuoteResponse(OMElement result) throws Exception {
AXIOMXPath xPath = new AXIOMXPath("//ns:last");
xPath.addNamespace("ns","http://services.samples/xsd");
OMElement last = (OMElement) xPath.selectSingleNode(result);
if (last != null) {
return last.getText();
} else {
throw new Exception("Unexpected response : " + result);
}
}
I can see the client is receiving the correct response. The print statement (marked with ********) gets executed and it prints the response payload as expected:
<ns:getQuoteResponse xmlns:ns="http://services.samples"><ns:return xmlns:ax21="http://services.samples/xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="ax21:GetQuoteResponse"><ax21:change>-2.3994058702324095</ax21:change><ax21:earnings>-9.185768238192317</ax21:earnings><ax21:high>-158.13498398871758</ax21:high><ax21:last>158.5652017864806</ax21:last><ax21:lastTradeTimestamp>Sun May 23 20:09:13 IST 2010</ax21:lastTradeTimestamp><ax21:low>-157.20036313216417</ax21:low><ax21:marketCap>5.393598252226892E7</ax21:marketCap><ax21:name>IBM Company</ax21:name><ax21:open>165.6030739863106</ax21:open><ax21:peRatio>24.08910588357344</ax21:peRatio><ax21:percentageChange>1.5441539764455583</ax21:percentageChange><ax21:prevClose>-155.38643858273318</ax21:prevClose><ax21:symbol>IBM</ax21:symbol><ax21:volume>18163</ax21:volume></ns:return></ns:getQuoteResponse>
But then the parseStandardQuoteResponse method fails with the following exception:

The same exact code works fine with the HTTP transport. So I guess this has something to do with the UDP transport. Any ideas?

Thanks for looking into this Andreas. I'll also run some debug sessions and
try to pin down the problem. Another interesting observation: If I clone the
response OMElement and pass that to the helper method, it will work fine. Or
if I get a string out of the response OMElement and convert that back to an
OMElement things will still work just fine.

Thanks for looking into this Andreas. I'll also run some debug sessions and
try to pin down the problem. Another interesting observation: If I clone the
response OMElement and pass that to the helper method, it will work fine. Or
if I get a string out of the response OMElement and convert that back to an
OMElement things will still work just fine.

Broken code introduced in WSCOMMONS-511. I will see if I can apply the

if instance declaration is
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
then the declaration for xsi:type="ax21:GetQuoteResponse"
which assumes your type must be a qname (does this definition exist?)
Here is example

Subject: Error While Invoking Service Over UDP
From: hiranya911@gmail.com
To: java-dev@axis.apache.org
Hi Devs,
I'm trying to invoke a simple web service over UDP. I have properly configured and exposed my service (SimpleStockQuoteService in Synapse) over UDP transport and I use the following client to invoke the service:
public static void main(String[] args) throws Exception {
String request =
"<m0:getQuote xmlns:m0=\"http://services.samples\">" +
"<m0:request>" +
"<m0:symbol>IBM</m0:symbol>" +
"</m0:request>" +
"</m0:getQuote>";
ConfigurationContext cfgCtx =
ConfigurationContextFactory.createConfigurationContextFromFileSystem(
CLIENT_HOME + "/client_repo",
CLIENT_HOME + "/client_repo/conf/axis2.xml");
ServiceClient client = new ServiceClient(cfgCtx, null);
client.engageModule("addressing");
Options options = new Options();
options.setTo(new EndpointReference("udp://localhost:9999/services/SimpleStockQuoteService?contentType=text/xml"));
options.setAction("urn:getQuote");
client.setOptions(options);
OMElement res = client.sendReceive(AXIOMUtil.stringToOM(request));
System.out.println(res); // ***************************************
client.cleanup();
System.out.println("VALUE: " + parseStandardQuoteResponse(res));
}
public static String parseStandardQuoteResponse(OMElement result) throws Exception {
AXIOMXPath xPath = new AXIOMXPath("//ns:last");
xPath.addNamespace("ns","http://services.samples/xsd");
OMElement last = (OMElement) xPath.selectSingleNode(result);
if (last != null) {
return last.getText();
} else {
throw new Exception("Unexpected response : " + result);
}
}
I can see the client is receiving the correct response. The print statement (marked with ********) gets executed and it prints the response payload as expected:
<ns:getQuoteResponse xmlns:ns="http://services.samples"><ns:return xmlns:ax21="http://services.samples/xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="ax21:GetQuoteResponse"><ax21:change>-2.3994058702324095</ax21:change><ax21:earnings>-9.185768238192317</ax21:earnings><ax21:high>-158.13498398871758</ax21:high><ax21:last>158.5652017864806</ax21:last><ax21:lastTradeTimestamp>Sun May 23 20:09:13 IST 2010</ax21:lastTradeTimestamp><ax21:low>-157.20036313216417</ax21:low><ax21:marketCap>5.393598252226892E7</ax21:marketCap><ax21:name>IBM Company</ax21:name><ax21:open>165.6030739863106</ax21:open><ax21:peRatio>24.08910588357344</ax21:peRatio><ax21:percentageChange>1.5441539764455583</ax21:percentageChange><ax21:prevClose>-155.38643858273318</ax21:prevClose><ax21:symbol>IBM</ax21:symbol><ax21:volume>18163</ax21:volume></ns:return></ns:getQuoteResponse>
But then the parseStandardQuoteResponse method fails with the following exception:

The same exact code works fine with the HTTP transport. So I guess this has something to do with the UDP transport. Any ideas?
Thanks,

Broken code introduced in WSCOMMONS-511. I will see if I can apply the
testkit to the UDP transport so that we can do some quality checks.

Broken code introduced in WSCOMMONS-511. I will see if I can apply the
testkit to the UDP transport so that we can do some quality checks.

RE: Error While Invoking Service Over UDP
Posted by Martin Gainty <mg...@hotmail.com>.
if instance declaration is
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
then the declaration for xsi:type="ax21:GetQuoteResponse"
which assumes your type must be a qname (does this definition exist?)
Here is example

Subject: Error While Invoking Service Over UDP
From: hiranya911@gmail.com
To: java-dev@axis.apache.org
Hi Devs,
I'm trying to invoke a simple web service over UDP. I have properly configured and exposed my service (SimpleStockQuoteService in Synapse) over UDP transport and I use the following client to invoke the service:
public static void main(String[] args) throws Exception {
String request =
"<m0:getQuote xmlns:m0=\"http://services.samples\">" +
"<m0:request>" +
"<m0:symbol>IBM</m0:symbol>" +
"</m0:request>" +
"</m0:getQuote>";
ConfigurationContext cfgCtx =
ConfigurationContextFactory.createConfigurationContextFromFileSystem(
CLIENT_HOME + "/client_repo",
CLIENT_HOME + "/client_repo/conf/axis2.xml");
ServiceClient client = new ServiceClient(cfgCtx, null);
client.engageModule("addressing");
Options options = new Options();
options.setTo(new EndpointReference("udp://localhost:9999/services/SimpleStockQuoteService?contentType=text/xml"));
options.setAction("urn:getQuote");
client.setOptions(options);
OMElement res = client.sendReceive(AXIOMUtil.stringToOM(request));
System.out.println(res); // ***************************************
client.cleanup();
System.out.println("VALUE: " + parseStandardQuoteResponse(res));
}
public static String parseStandardQuoteResponse(OMElement result) throws Exception {
AXIOMXPath xPath = new AXIOMXPath("//ns:last");
xPath.addNamespace("ns","http://services.samples/xsd");
OMElement last = (OMElement) xPath.selectSingleNode(result);
if (last != null) {
return last.getText();
} else {
throw new Exception("Unexpected response : " + result);
}
}
I can see the client is receiving the correct response. The print statement (marked with ********) gets executed and it prints the response payload as expected:
<ns:getQuoteResponse xmlns:ns="http://services.samples"><ns:return xmlns:ax21="http://services.samples/xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="ax21:GetQuoteResponse"><ax21:change>-2.3994058702324095</ax21:change><ax21:earnings>-9.185768238192317</ax21:earnings><ax21:high>-158.13498398871758</ax21:high><ax21:last>158.5652017864806</ax21:last><ax21:lastTradeTimestamp>Sun May 23 20:09:13 IST 2010</ax21:lastTradeTimestamp><ax21:low>-157.20036313216417</ax21:low><ax21:marketCap>5.393598252226892E7</ax21:marketCap><ax21:name>IBM Company</ax21:name><ax21:open>165.6030739863106</ax21:open><ax21:peRatio>24.08910588357344</ax21:peRatio><ax21:percentageChange>1.5441539764455583</ax21:percentageChange><ax21:prevClose>-155.38643858273318</ax21:prevClose><ax21:symbol>IBM</ax21:symbol><ax21:volume>18163</ax21:volume></ns:return></ns:getQuoteResponse>
But then the parseStandardQuoteResponse method fails with the following exception:

The same exact code works fine with the HTTP transport. So I guess this has something to do with the UDP transport. Any ideas?
Thanks,
