hi,
i'am using castor-xml-1.0.5 but even with 1.2 the problem remains:
i cannot completely unmarshal an object from the xml i have marshalled before
using a mapping file.
i have a class as simple as this:
package com.xyz;
import java.util.List;
import java.util.ArrayList;
public class A
{
private List<String> strings;
public A()
{
this.strings = new ArrayList<String>(3);
this.strings.add("one");
this.strings.add("two");
this.strings.add("three");
}
public void setStrings(List<String> strings)
{
this.strings = strings;
}
public List<String> getStrings()
{
return this.strings;
}
}
the mapping file looks as follows
<mapping>
<class name="com.xyz.A">
<description>Mapping for Class com.xyz.A</description>
<map-to xml="A" ns-uri="http://xyz.com/A"; ns-prefix="a" />
<field name="strings" collection="arraylist" type="string"
container="false">
<bind-xml name="b" node="element"/>
</field>
</class>
</mapping>
it marshals:
<?xml version="1.0" encoding="UTF-8"?>
<a:A xmlns:a="http://xyz.com/A";>
<!-- notice that there is no namespace anymore ??? -->
<b>
<string>one</string>
<string>two</string>
<string>three</string>
</b>
</a:A>
ok, the structure of the xml is finally what i want.
i use the 'container="false"' attribute in the 'field' element to get one
'string' element per list item (as suggested on the how-to page). otherwise all
strings were merged into a single 'string' element containing "onetwothree"
(however - all elements with correct namespaces). but for some reason castor
suppresses the namespace when i use the container attribute.
then, if i ignore the namespace issue and try to unmarshal the xml, i don't get
back my list of strings any more. as castor failed to handle the 'b' element
throwing a MarshalException ('unable to find FieldDescriptor for 'b') first, i
have set the 'ignoreExtraElements' property of the unmarshaller to 'true'
(using a 'location' attribute with 'b/string' in the 'bind-xml' element of my
mapping instead didn't help as well).
my test looks as follows
public void testMarshalUnmarshal()
throws Exception
{
A a = new A();
Mapping mapping = new Mapping();
mapping.loadMapping("a-mapping.xml");
StringWriter writer = new StringWriter();
// global marshaller
marshaller.setWriter(writer);
marshaller.setMapping(mapping);
marshaller.marshal(a);
String marshalled = writer.toString();
if (logger.isDebugEnabled) logger.debug(marshalled);
// global unmarshaller
unmarshaller.setMapping(mapping);
unmarshaller.setIgnoreExtraAttributes(true);
unmarshaller.setIgnoreExtraElements(true);
StringReader reader = new StringReader(marshalled);
Object unmarshalled = unmarshaller.unmarshal(reader);
assertNotNull(unmarshalled);
assertTrue(unmarshalled instanceof A);
// this assertion fails
assertNotNull(((A) unmarshalled).getStrings());
assertEquals(a.getStrings().size(), ((A) unmarshalled).getStrings().size());
}
in the end i am still looking for a proper mapping.xml to get the following xml:
<?xml version="1.0" encoding="UTF-8"?>
<a:A xmlns:a="http://xyz.com/A";>
<a:b>
<a:string>one</a:string>
<a:string>two</a:string>
<a:string>three</a:string>
</a:b>
</a:A>
which i can successfully unmarshal again.
any kind of coaching would be nice!
thx in advance,
