Paul,
Thanks for the reply... I'm not very handy with XML (which is why I'm
trying to use xbeans :-)) so I'm not exactly sure if I can do what you
are recommending given my system constraints. We have product that we
can't really modify that produces XML. I want to bind to that xml with
xbeans.
I wrote the xsd, here's a piece of it:
<!-- begin share type definitions -->
<xs:complexType name="savingShareType">
<xs:sequence>
<xs:element name="suffix" type="xs:token" />
<xs:element name="description" type="xs:token" />
<xs:element name="beginningBalance" type="xs:decimal" />
<xs:element name="endingBalance" type="xs:decimal" />
<xs:element name="apyEarned" type="xs:float" minOccurs="0" />
<xs:element name="overdraftFees" type="xs:decimal" minOccurs="0"
/>
<xs:element name="returnedFees" type="xs:decimal" minOccurs="0"
/>
<xs:element name="shareTransaction"
type="stmt:shareTransactionType"
minOccurs="0" maxOccurs="unbounded" />
<xs:element name="ytdDividends" type="xs:decimal" />
</xs:sequence>
</xs:complexType>
<xs:complexType name="draftShareType">
<xs:sequence>
<xs:element name="suffix" type="xs:token" />
<xs:element name="description" type="xs:token" />
<xs:element name="beginningBalance" type="xs:decimal" />
<xs:element name="endingBalance" type="xs:decimal" />
<xs:element name="apyEarned" type="xs:float" minOccurs="0" />
<xs:element name="overdraftFees" type="xs:decimal" minOccurs="0"
/>
<xs:element name="returnedFees" type="xs:decimal" minOccurs="0"
/>
<xs:element name="serviceCharges" type="xs:decimal"
minOccurs="0" />
<xs:element name="numChecksPaid" type="xs:nonNegativeInteger"
minOccurs="0" />
<xs:element name="shareTransaction"
type="stmt:shareTransactionType"
minOccurs="0" maxOccurs="unbounded" />
<xs:element name="ytdDividends" type="xs:decimal" />
</xs:sequence>
</xs:complexType>
<xs:complexType name="certificateShareType">
<xs:sequence>
<xs:element name="suffix" type="xs:token" />
<xs:element name="description" type="xs:token" />
<xs:element name="beginningBalance" type="xs:decimal" />
<xs:element name="endingBalance" type="xs:decimal" />
<xs:element name="apyEarned" type="xs:float" minOccurs="0" />
<xs:element name="issueDate" type="xs:date" minOccurs="0" />
<xs:element name="maturityDate" type="xs:date" minOccurs="0" />
<xs:element name="certRate" type="xs:float" minOccurs="0" />
<xs:element name="shareTransaction"
type="stmt:shareTransactionType"
minOccurs="0" maxOccurs="unbounded" />
<xs:element name="ytdDividends" type="xs:decimal" />
</xs:sequence>
</xs:complexType>
Notice they all begin and end with the same fields, and it's the content
in the middle that changes. I can't modify the program that produces
the XML so I can't "move" the transactions and dividends elements.
In my java code, I want to get a SavingShare, DraftShare and
CertificateShare...all of which extend Share.
How can I have all three types extend a base type that holds the common
content while still allowing for the unbounded transaction type?
My other option is to run the xml through something that reorganizes the
content before using xbeans...which seems silly.

Subject: RE: implementing a custom interface
If I understand you correctly, in your XSD create a base type with the
common attributes. Create types for each of your 3 derived from the
base type. In your code you can refer to each as basetype and for
specifics test with instanceof.

Subject: implementing a custom interface
I have three types in my XSD: Savings, Checking, Certificate.
Is it possible to add something (to the .xsdconfig?) that makes all
three types implement an interface I created?
I want my beans to be like this:
Product
getStaringBal()
getEndingBal()
Savings implements Product
getSavingsSpecificStuff()
Checking implements Product
getCheckingSpecificStuff()
make sense?
