John Kaputin updated WSCOMMONS-120:
-----------------------------------
Attachment: XmlSchema_equals_patch.txt
Implements the equals(Object) method for XmlSchema.
> XmlSchema.equals(Object) returns a false positive result
> --------------------------------------------------------
>
> Key: WSCOMMONS-120
> URL: http://issues.apache.org/jira/browse/WSCOMMONS-120
> Project: WS-Commons
> Issue Type: Bug
> Components: XmlSchema
> Reporter: John Kaputin
> Attachments: XmlSchema_equals_patch.txt
>
>
> The XmlSchema class inherits the equals(Object) method from XmlSchemaObject.
> This method uses line number, line position and sourceURI for equality
> checking, however line number and position are always zero (they are not
> used yet?). This can cause a false positive when checking equality of two
> different schemas that share the same source URI.
> For example, the WSDL 2.0 testcase at [1] has two inlined schemas. For
> XmlSchema1.equals(XmlSchema2), both XmlSchema objects will have line number
> zero, line position zero and the WSDL URI as their sourceURI and
> XmlSchemaObject.equals will return true, even though in this case the two
> inlined schemas have different target namespaces and xs:include different
> schema documents.

> I think a solution is to create an equals method on XmlSchema which invokes
> super.equals (i.e. from XmlSchemaObject) and adds further equality checking
> specific to XmlSchema. I have tried the attached patch which fixes my
> testcase, although it may require more equality checking logic in the equals
> method
> to be more useful generally.
