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

Date: Sun, 23 May 2010 20:12:15 +0530 Subject: Error While Invoking Service Over UDP From: hiranya...@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: Exception in thread "main" org.apache.axiom.om.OMException: com.ctc.wstx.exc.WstxUnexpectedCharException: Illegal character (NULL, unicode 0) encountered: not valid in any content at [row,col {unknown-source}]: [1,1234] at org.apache.axiom.om.impl.builder.StAXOMBuilder.next(StAXOMBuilder.java:267) at org.apache.axiom.om.impl.llom.OMDocumentImpl.buildNext(OMDocumentImpl.java:130) at org.apache.axiom.om.impl.llom.OMNodeImpl.getNextOMSibling(OMNodeImpl.java:122) at org.apache.axiom.om.impl.llom.OMElementImpl.getNextOMSibling(OMElementImpl.java:344) at org.apache.axiom.om.impl.traverse.OMChildrenIterator.next(OMChildrenIterator.java:102) at org.jaxen.util.DescendantAxisIterator.next(DescendantAxisIterator.java:127) at org.jaxen.expr.DefaultStep.evaluate(DefaultStep.java:154) at org.jaxen.expr.DefaultLocationPath.evaluate(DefaultLocationPath.java:140) at org.jaxen.expr.DefaultAbsoluteLocationPath.evaluate(DefaultAbsoluteLocationPath.java:113) at org.jaxen.expr.DefaultXPathExpr.asList(DefaultXPathExpr.java:102) at org.jaxen.BaseXPath.selectNodesForContext(BaseXPath.java:674) at org.jaxen.BaseXPath.selectNodes(BaseXPath.java:213) at org.jaxen.BaseXPath.selectSingleNode(BaseXPath.java:234) at org.wso2.test.tools.Axis2UDPClient.parseStandardQuoteResponse(Axis2UDPClient.java:63) at org.wso2.test.tools.Axis2UDPClient.main(Axis2UDPClient.java:56) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:90) Caused by: com.ctc.wstx.exc.WstxUnexpectedCharException: Illegal character (NULL, unicode 0) encountered: not valid in any content at [row,col {unknown-source}]: [1,1234] at com.ctc.wstx.sr.StreamScanner.constructNullCharException(StreamScanner.java:615) at com.ctc.wstx.sr.StreamScanner.throwInvalidSpace(StreamScanner.java:644) at com.ctc.wstx.sr.StreamScanner.throwInvalidSpace(StreamScanner.java:635) at com.ctc.wstx.sr.BasicStreamReader.readSpacePrimary(BasicStreamReader.java:4914) at com.ctc.wstx.sr.BasicStreamReader.nextFromProlog(BasicStreamReader.java:2003) at com.ctc.wstx.sr.BasicStreamReader.nextFromTree(BasicStreamReader.java:2647) at com.ctc.wstx.sr.BasicStreamReader.next(BasicStreamReader.java:1019) at org.apache.axiom.util.stax.wrapper.XMLStreamReaderWrapper.next(XMLStreamReaderWrapper.java:221) at org.apache.axiom.util.stax.dialect.DisallowDoctypeDeclStreamReaderWrapper.next(DisallowDoctypeDeclStreamReaderWrapper.java:33) at org.apache.axiom.util.stax.wrapper.XMLStreamReaderWrapper.next(XMLStreamReaderWrapper.java:221) at javax.xml.stream.util.StreamReaderDelegate.next(StreamReaderDelegate.java:60) at org.apache.axiom.om.impl.builder.SafeXMLStreamReader.next(SafeXMLStreamReader.java:221) at org.apache.axiom.om.impl.builder.StAXOMBuilder.parserNext(StAXOMBuilder.java:636) at org.apache.axiom.om.impl.builder.StAXOMBuilder.next(StAXOMBuilder.java:188) ... 19 more The same exact code works fine with the HTTP transport. So I guess this has something to do with the UDP transport. Any ideas?
