Major Description
I tried to create a java client with wsdl2java. With version 1.7.0 and older ones everything is fine. But since version 1.7.1 the nillable="true" attribute is ignored. Here is a small example wsdl:
<definitions name="StockQuote" targetNamespace="http://example.com/stockquote.wsdl" xmlns:tns="http://example.com/stockquote.wsdl" xmlns:xsd1="http://example.com/stockquote.xsd" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns="http://schemas.xmlsoap.org/wsdl/"> <types> <schema targetNamespace="http://example.com/stockquote.xsd" xmlns="http://www.w3.org/2001/XMLSchema"> <element name="TradePriceRequest"> <complexType> <all> <element name="tickerSymbol" nillable="true" type="string"/> </all> </complexType> </element> <element name="TradePrice"> <complexType> <all> <element name="price" nillable="true" type="float"/> </all> </complexType> </element> </schema> </types> <message name="GetLastTradePriceInput"> <part name="body" element="xsd1:TradePriceRequest"/> </message> <message name="GetLastTradePriceOutput"> <part name="body" element="xsd1:TradePrice"/> </message> <portType name="StockQuotePortType"> <operation name="GetLastTradePrice"> <input message="tns:GetLastTradePriceInput"/> <output message="tns:GetLastTradePriceOutput"/> </operation> </portType> <binding name="StockQuoteSoapBinding" type="tns:StockQuotePortType"> <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/> <operation name="GetLastTradePrice"> <soap:operation soapAction="http://example.com/GetLastTradePrice"/> <input> <soap:body use="literal"/> </input> <output> <soap:body use="literal"/> </output> </operation> </binding> <service name="StockQuoteService"> <documentation>My first service</documentation> <port name="StockQuotePort" binding="tns:StockQuoteSoapBinding"> <soap:address location="http://example.com/stockquote"/> </port> </service> </definitions>
For creating the client I use the -u option. The problem appears in the Factory's parse method for the defined types. For example for TradePrice.java from the given wsdl above:
Genereated code from version 1.7.0 (snippet from Factory parse method):
TradePrice.java
if (!"true".equals(nillableValue) && !"1".equals(nillableValue)) { java.lang.String content = reader.getElementText(); object.setPrice(org.apache.axis2.databinding.utils.ConverterUtil.convertToFloat( content)); } else { object.setPrice(java.lang.Float.NaN); reader.getElementText(); // throw away text nodes if any. }
Genereated code from version 1.7.1 (snippet from Factory parse method):
TradePrice.java
if ("true".equals(nillableValue) || "1".equals(nillableValue)) { throw new org.apache.axis2.databinding.ADBException( "The element: " + "price" + " cannot be null"); } java.lang.String content = reader.getElementText(); object.setPrice(org.apache.axis2.databinding.utils.ConverterUtil.convertToFloat( content));
So as you can see, in 1.7.1 the price element is handled as a non nillable value although it is nillable. So if the server sends a repsonse with price = null the client will throw an exception although everything is fine...
