Subject Re: minOccurs="0" gummed up sometime between 2003-11-5 and2003-12-5
Date Mon, 08 Dec 2003 21:43:27 GMT

20109 says that WSDL2Java generates wrong code in the sense that it replaces xsd:boolean with

soapenc equivalent. This behavior does not existing in latest CVS. Hence i closed the bug.

Please open a new bug with a stripped down test case for your specific problem - "when
minOccurs="0" is specified use java.lang.Integer instead of int".
