Org.xml.sax.SAXException:SimpleDeserializer encountered a child element..

Question

Hi All,
I created a following program using "GetReportDefintion" method provided by BI Publisher Web Services

        final String bipEndpoint = "http://localhost:9704/xmlpserver/services/PublicReportService?wsdl";
        final String bipNamespace = "http://xmlns.oracle.com/oxp/service/PublicReportService";

        Service service = new Service();

        ReportDefinition reportDefn = (ReportDefinition) call.invoke(
            new Object[] { xdofile, "Administrator", "Administrator"});
        System.out.println("Report Definition Returns with \n Default Output Format = " + reportDefn.getDefaultOutputFormat());
        ParamNameValue params [] = reportDefn.getReportParameterNameValues();
        if (params != null) {
            for (int i = 0; i < params.length; i++) {
                System.out.print("Parameter " + params.getName() + ":");
if (params[i].getValues() != null) {
for (int j = 0; j < params[i].getValues().length; j++)
System.out.print(" " + params[i].getValues()[j]);
} else
System.out.print(" null");
System.out.println(" - multiple values? " + params[i].isMultiValuesAllowed());
System.out.println("END TESTING getReportDefinition");
}catch(Exception e){
e.printStackTrace();
I am getting following exception message. Anyone has any ideas what could be the mistake ?

Hi Sookie,
I found the problem is with couple of child parameters are not registered the deserializer. There're couple of additional classes needs to be registerd.
// register the TemplateLabelValue class
QName templateval = new QName(bipNamespace, "TemplateFormatLabelValue");
Class cls = TemplateFormatLabelValue.class;
call.registerTypeMapping(cls, templateval, BeanSerializerFactory.class, BeanDeserializerFactory.class);
// register the TemplateLabelValues class
QName templatevals = new QName(bipNamespace, "TemplateFormatsLabelValues");
cls = TemplateFormatsLabelValues.class;
call.registerTypeMapping(cls, templatevals, BeanSerializerFactory.class, BeanDeserializerFactory.class);
Could you please give it a try?
Thanks.
