> I'm trying to build my web service using Axis2 1.3 from WSDL already I have,
> but the deployed web service doesn't work because of NullPointerException in
> OMSerializerUtil.
> I have tried:
> 1. Using wsdl2java, generating skeleton codes from the wsdl attached to this
> report.
> 2. Build an aar file from skeletons and deploy it on Tomcat/Axis2 server.
> 3. Send SOAP envelope like this:
> <?xml version="1.0" encoding="UTF-8"?>
> <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";
> xmlns:ns1="http://adcentric.nazuki.jp/soap/v2/Analyze/Service.asmx";>
> <soapenv:Body>
> <ns1:AnalyzeType01>
> <ns1:License>a</ns1:License>
> <ns1:URL>b</ns1:URL>
> <ns1:Text>c</ns1:Text>
> </ns1:AnalyzeType01>
> </soapenv:Body>
> It causes server-side errors like this:
> 2007-11-27 17:24:34,608 [http-8080-Processor24] ERROR
