hi,
i'm a total newbie to jixb so this might be more a question of
understanding than of a problem. i went through the mailing list
archive, found some interresting things but nothing solved my
problems, so i'm ending up here ;-)
think about the following binding:
<?xml version="1.0" encoding="ISO-8859-2"?>
<binding>
<mapping name="customer" class="data.Customer" flexible="true"
ordered="false" allow-repeats="true">
<value name="id" set-method="setJiXBId" get-method="getJiXBId"/>
<value name="first" set-method="setJiXBFirstName" get-
method="getJiXBFirstName"/>
<value name="last" set-method="setJiXBLastName" get-
method="getJiXBLastName"/>
<collection field="addresses" flexible="true" ordered="false">
<structure name="address" type="data.Address" flexible="true"
ordered="false">
<value name="id" set-method="setJiXBId"
get-method="getJiXBId"/>
<value name="street" set-method="setJiXBStreet" get-
method="getJiXBStreet" usage="optional"/>
<value name="city" set-method="setJiXBCity" get-
method="getJiXBCity" usage="optional"/>
</structure>
</collection>
</mapping>
</binding>
this does not compile, jixb complains about the following:
[bind] Error: All child components must define element names
for flexible='true'; on collection element at (line 7, col 66, in C:/
JavaDev322/JiXB Test/src/customer_binding.xml)
[bind] Error running binding compiler
[bind] org.jibx.runtime.JiBXException: Binding C:/JavaDev322/
JiXB Test/src/customer_binding.xml is unusable because of validation
errors
problem is: we get XML data that could have more elements than we
expect, but we simply do not need to take care of this. but of course
we must get jixb to ignore these during runtime.
i've tried several other ways to solve this:
i removed the collection element and added getters and setters to the
structure (the setter simply adds an "address" to the list) and set
"allow-repeats" to true.
with this approach i ended up with a very strange situation. giving
the following input, i received a strange result.
input:
<?xml version="1.0" encoding="ISO-8859-2"?>
<customer>
<id>1234</id>
<first>Heinz</first>
<last>Prueller</last>
<asdasd>asasd</asdasd>
<address>
<id>111</id>
<street>Daham 1</street>
<city>1110 Wien</city>
</address>
<address>
<id>222</id>
<street>Daham 2</street>
<city>2220 Wien</city>
<kasperl>asdasd</kasperl>
</address>
<address>
<id>333</id>
<street>Daham 3</street>
<city>3330 Wien</city>
</address>
</customer>
outcome:
Adding [EMAIL PROTECTED] 1][city=1110
Wien]]
Adding [EMAIL PROTECTED] 2][city=2220
Wien]]
Adding [EMAIL PROTECTED] 3][city=3330
Wien]]
Result: [EMAIL PROTECTED]
[EMAIL PROTECTED]
[[id=333][street=Daham 3][city=3330 Wien]]]
[EMAIL PROTECTED] 3][city=3330
[EMAIL PROTECTED] 3]
[city=3330 Wien]]]]]
as you can see, the three address object were passed to my addAddress
() method with the correct values, but the final collection holds
three address objects which all hold the same data!!!! weird!
so my question is:
how can i define a binding that either uses collections or can deal
with collections, but allows "unknown" XML elements to exist in the
data coming in without getting exceptions during runtime?
br,
guenther
