Re: [castor-dev] need help wrapping elements

[Ben]

I'm also interested in knowing related to this. I tried the castor tool to
generate the mapping file and code generator.
<foo>
    <bar>
        <left></left>
        <left></left>
        <left></left>
        <right></right>
        <right></right>
        <right></right>
    </bar>
</foo>

For this, it creates classes left and right are type of bar. It doesn't work
for some reason.

But if I change the structure as follows, then I can get it properly.
<foo>
    <bar>
      <lbar>
          <left></left>
        <left></left>
        <left></left>
      </lbar>
        <rbar>
        <right></right>
        <right></right>
        <right></right>
        </rbar>
    </bar>
</foo>

Can someone explain me, Is there a way to get the mapping for the first
version, without changing the XML.

 Hi-

I've just started using Castor and am excited about its potential, but I've
run
into a problem.  I would like to map two fields to a single wrapper element.
I
tried using the 'location' attribute of bind-xml, but it yielded two wrapper
elements. The example below, I hope, will make this clearer.  Is it possible
to nest multiple elements within a single wrapper element?

Thanks,
Dan Marcus

Given a bean like this:

public class Foo {
    private int barLeft;
    private int barRight;

    public int getBarLeft(){
        return barLeft;
    }

    public int getBarRight(){
        return barRight;
    }
}

I would like to create xml like this:
<foo>
    <bar>
        <left/>         <!-- Note left and right are both within a single
bar-->
        <right/>
    </bar>
</foo>

Unfortunately, using the mapping below, it looks like this:
<foo>
    <!-- Note the 2 bar elements! -->
    <bar>
        <left>0</left>
    <bar>
    <bar>
        <right>5</right>
    <bar>
</foo>

Here's the mapping:
<class name="Foo">
    <map-to xml="foo"/>


    <field name "barLeft" type="integer">
          <bind-xml name="left" location="bar" node="element"/>
    </field>
    <field name "barLeft" type="integer">
          <bind-xml name="right" location="bar" node="element"/>
    </field>
</class>
