[jboss-dev-forums] [Design of JBossXB] - Unmarshaller: xsd:choice with minOccurs

Suppose, I have the following XSD bit: | <xsd:element name="application-policy"> | <xsd:complexType> | <xsd:sequence> | <xsd:choice minOccurs="0"> | <xsd:element ref="jbsx:authentication"/> | <xsd:element ref="jbsx:authentication-jaspi"/> | </xsd:choice> | <xsd:element ref="jbsx:authorization" minOccurs="0"/> | | </xsd:sequence> | </xsd:complexType> | </xsd:element> | I get the following exception: | Caused by: org.jboss.xb.binding.JBossXBRuntimeException: Requested element {urn: | jboss:security-config:5.0}authorization is not allowed in this position in the s | equence. A model group with minOccurs=1 that doesn't contain this element must follow. | at org.jboss.xb.binding.sunday.unmarshalling.SequenceBinding$1.startElem | ent(SequenceBinding.java:271) | at org.jboss.xb.binding.sunday.unmarshalling.ModelGroupBinding$Cursor.st | artElement(ModelGroupBinding.java:185) | at org.jboss.xb.binding.sunday.unmarshalling.SundayContentHandler.startE | lement(SundayContentHandler.java:280) | at org.jboss.xb.binding.parser.sax.SaxJBossXBParser$DelegatingContentHan | dler.startElement(SaxJBossXBParser.java:381) | at org.apache.xerces.parsers.AbstractSAXParser.startElement(Unknown Sour | ce) | It seems that XB does not like an xsd:choice with minOccurs/maxOccurs. My xml looks like: | <jbsx:application-policy name="jboss-web-policy"> | <jbsx:authorization> | <jbsx:policy-module code="org.jboss.security.authorization.modules.DelegatingAuthorizationModule" flag="required"/> | </jbsx:authorization> | </jbsx:application-policy> | I am trying to avoid the optional authentication element.
