Hi everybody!
I`m new to betwixt and want to use it to dump and import our database
tables.
Dumping is ok, altough I have some questions, too.
The problem is, that every reference to other objects is null when I read
the XML file.
( I have defined: beanReader.getBindingConfiguration().setMapIDs(true); )
I have the following structure in the XML File:
----------------------- dump.xml ----------------------------------
<ArrayList>
<ArrayList>
<Person id="1"..... />
...
</ArrayList>
...
<ArrayList>
<Projekt id="12"...>
<manager idref="13"/> --> Reference to Person
</Projekt>
</ArrayList>
---------------------------------------------------------------------
I am reading the XML file with this Reader (btw: I`m also new to Digester
and tried a bit to get the ArrayList structure out of the file, I got no
result when only using beanReader.registerBeanClass(...) ):
-------------------- Dumper.java ------------------------------------
StringReader xmlReader = new StringReader("dump.xml");
BeanReader beanReader = new BeanReader();
beanReader.getXMLIntrospector().setWrapCollectionsInElement(false);
beanReader.getXMLIntrospector().setAttributesForPrimitives(true);
beanReader.getBindingConfiguration().setMapIDs(true);
beanReader.registerBeanClass("ArrayList", ArrayList.class);
beanReader.addObjectCreate("ArrayList/ArrayList", ArrayList.class);
beanReader.addSetNext("ArrayList/ArrayList", "add");
beanReader.registerBeanClass("ArrayList/ArrayList/Person", Person.class);
beanReader.addSetNext("ArrayList/ArrayList/Person", "add");
beanReader.registerBeanClass("ArrayList/ArrayList/Role", Role.class);
beanReader.addSetNext("ArrayList/ArrayList/Role", "add");
beanReader.registerBeanClass("ArrayList/ArrayList/Arbeitszeit",
Arbeitszeit.class);
beanReader.addSetNext("ArrayList/ArrayList/Arbeitszeit", "add");
beanReader.registerBeanClass("ArrayList/ArrayList/Projekt", Projekt.class);
beanReader.addSetNext("ArrayList/ArrayList/Projekt", "add");
Object result = beanReader.parse(new File("dump.xml"));
------------------------------------------------------------------------
With this configuration I get an ArrayList with ArrayLists.. and so on,
but - how mentioned above - the idref is null:
---------------------- OUTPUT -----------------------------------------
Projekt:
id ="0"
manager=null
name ="Projekt1"
-----------------------------------------------------------------------
Is there anything I forgot? Or am I doing something wrong? I`d really
appreciate a tip!
Another question about wrinting a bean to XML:
I`d like to rename my ArrayLists (only for better reading), e.g. the
root-ArrayList to "Data" and the inner ones to "persons", "project" etc.
Is this possible? I tried, but always get empty tags (also with using
class-property in element-tag). But this is only "nice to have"...
Thanks in advance!
Have a nice day!
Birgit
