Hi Apache SOAP2.2 checks for 'Null' values (when using SOAP-encoding style) by checking for the attribute "xsi:null=true".
(see encoding/soapenc/SoapEncUtils.java:isNull(Element)) The SOAP 1.1 spec says that NULL values are represented by setting the xsi:null attribute value to "1". i.e., "xsi:null='1' This variance in Apache is causing interoperability problems. Can any of the Apache-soap folks confirm that this is a bug, and if so, is there an upcoming release where it can be fixed ? thanx -john
