Hello,
since there is no commons-user-List, i'll try my luck here.
I am using Turbine along with Torque as an OM-Tool.
Some data of an object generated with Torque should be stored in a XML-DB (Xindice, to
be ecaxt).
Now i thought i might use betwixt to map the wanted attributes to a nice XML and put
it in the DB.
Now i first wanted to look at the example of betwixt, for some reason i can't (ant
failes
the build cause it doesn't find org.apache.commons.betwixt.strategy.NameMapper, which
is in the
source-directory, but not in the jar - why's that? ).
Well, after that i tried to figure it out, and i now have a prettyprinted XML from the
OM-Class,
though there's all attributes in it. Probably i'm using it all wrong, but the
documentation is rather
short, so i ought someone here could provide me with some insight ^^ (pretty please)
my OM-Class is named KnowledgeObject and to test it i want to generate an xml just
with the
subject and description attribute in it. I made a KnowledgeObject.betwixt-File which
looks this way:
<?xml version="1.0" encoding="UTF-8" ?>
<KnowledgeObject primitiveTypes="attribute">
<element name="subject" property="subject"/>
<element name="description" property="description"/>
</<KnowledgeObject >
and i put that in the class-directory, actually exaclty in the directory the om-Class
also is (KnowledgeObject.class)
In the Class KnowledgeObjectPeer i made a new method which should also create the xml
from the OM-Class.
public static ObjectKey doInsert(Criteria criteria, KnowledgeObject ko) throws
Exception
{
// insert the data in the relational DB
ObjectKey result = BaseKnowledgeObjectPeer.doInsert(criteria);
ko.setPrimaryKey(result);
// Use Betwixt to create an XML file from the Knowledge Object
BeanWriter beanWriter = new BeanWriter(System.out);
beanWriter.enablePrettyPrint();
beanWriter.write(ko);
} // doInsert
Now this produces some nice looking XML, though i only want something like this to be
created
(and i thought with the betwixt-file i ruled it).
<KnowledgeObject id="2">
<subject>Subject</subject>
<description>Description</description>
</KnowledgeObject
How do i tell the BeanWriter to use the betwixt-file? There is no error thrown, so i
think it doesn't use
the betwixt file at all ... ^^;;
