Either support <sequence minOccurs="0"> or print an error from WSDL2Java
------------------------------------------------------------------------
Key: AXIS-2607
URL: https://issues.apache.org/jira/browse/AXIS-2607
Project: Apache Axis
Issue Type: Improvement
Components: WSDL processing
Affects Versions: 1.4
Environment: Windows XP Professional
Version2002
SP2
Intel Pentium 4
Java 1.5.0_06
Reporter: Jon Carmignani
Priority: Minor
I attempted to use a sequence that I wanted to not require its use, but if it
was there, I wanted all elements to be present given their stated occurrence
limits. I used the following in my XSD (referenced from the WSDL).
<xsd:complexType name="programDef">
<xsd:sequence>
<xsd:element name="subprogram"
type="snwma_dl:subprogramDef"
maxOccurs="unbounded"
minOccurs="0"
/>
<xsd:sequence minOccurs="0">
<xsd:element name="desc" type="snwma_s:string500" />
<xsd:element name="statusInd" type="snwma_s:string1" />
<xsd:element name="abbr" type="snwma_s:string4" />
<xsd:element name="reviewFy" type="xsd:int"
minOccurs="0" />
<xsd:element name="bAndRNumber" type="snwma_s:string20"
minOccurs="0" />
<xsd:element name="displayOrder" type="xsd:long"
minOccurs="0" />
<xsd:element name="auditCols"
type="snwma_s:auditColsDef" />
</xsd:sequence>
</xsd:sequence>
<xsd:attribute name="key" type="xsd:long" />
<xsd:attributeGroup ref="snwma_s:actions"/>
</complexType>
The namespaces are all defined, so that isn't my issue. This passes through
WSDL2Java with no problems, creating the classes I would expect. The problem I
am having is that the parser for incoming messages still requires that all of
the elements without the minOccurs="0" attribute appear. While I can
understand why the minOccurs attribute isn't supporded on sequences for values
larger than 1, I think it would be useful to support minOccurs="0" simply so I
don't have to have an additional wrapper class around optional groups of data.
