SOAP-DEV: Would it be possible for SOAP 2.3 to support xsi:nil when 2001 schema is specified?
Peter/Thomas: I just committed a change to Axis which should insert xsi:type on elements which contain xsi:nil attributes. This is not a complete solution as Apache SOAP 2.2 will interpret such strings as "" instead of null. For other datatypes, you may see errors such as java.lang.NumberFormatException. You should also be able to achieve similar results without the Axis change by adding an isd:map entry in your deploymentDescriptor.xml for :charSet. I would recommend doing this for interop reasons with non Apache SOAP stacks which may not insert xsi:type. For interop tests including xsi:nil, you might want to look http://www.jin.gr.jp/~nahi/Ruby/SOAP4R/wiki.cgi?cmd=view;name=InteropResults - Sam Ruby Peter Fischer3/Germany/IBM@IBMDE on 04/29/2002 05:57:22 AM To: Sam Ruby/Raleigh/IBM@IBMUS cc: Thomas Schaeck/Germany/IBM@IBMDE Subject: Axis: interop Hi Sam, i am developing the WebServices part of the IBM Portal where portlets can be invoked remotely via SOAP. At the moment i am using SOAP 2.2 but i just started playing around with Axis. Now i've tried to port the client first to use Axis but i am running into an interop problem with null values with the existing server that is still using SOAP 2.2 regarding null values: while the SOAP2.2 client encodes the null values containing the type of the null value like: <charSet xsi:type="xsd:string" xsi:null="true"/> the Axis client just transferes the nil value: <charSet xsi:nil="true"/> This is an interoperability problem as the server did not necessarily have to specify how to (de)serialize simple types as strings for SOAP 2.2 - and that's the way how we shipped the Portal Server. If i want to use an Axis client with an old SOAP2.2 based version of the portal it will not work as it does not know how to handle untyped values: No Deserializer found to deserialize a ':charSet' using encoding style 'http://schemas.xmlsoap.org/soap/encoding/' Now here my questions: - Is there a way to configure Axis to add the types to null values? Otherwise i would report that as a defect via bugzilla... - Could you please add null values to the Axis interop tests?
