Re: [castor-user] DLL Generation from OR Mapping in Castor possible without XDoclet?

[Ng Keng Yap]

Dear Bruce,

Thanks for the reply.

Do you mean that I can enclose the castor javadoc tag  in the documentation in XSD, then use the Castor Source generator to generate my Java Objects based on the XSD, the tags will appear in the generated java source code? And then by using XDoclet, I can generate the DDL I wanted?

What a great news to me, please add this 'million dollar' information to the Castor documetation on the web site asap so that more people will benefit from it.

 

Thanks.

 

Cheers,

Ng Keng Yap

I ran into this exact problem while authoring the Castor Live book

and I've found a partial way around it. XML Schema supports

documentation and the Source Generator will will carry this

documentation through to the generated code. Below is a small example

of an XSD containing XDoclet tags:

<element name="book" maxOccurs="unbounded">

     <annotation>

         <documentation>

         @castor.class name="com.sourcebeat.castorlive.sample.model.Book"

         id="book-id" table="book"

         </documentation>

     </annotation>

     <complexType>

         <sequence>

             <element name="title" type="string">

                 <annotation>

                     <documentation>

                     @castor.field type="string"

                     @castor.field-sql name="title" type="varchar"

                     @castor.field-xml name="title" node="attribute"

                     </documentation>

                 </annotation>

             </element>

         ...

             <element name="author" type="author">

                 <annotation>

                     <documentation>

                     @castor.field type="com.sourcebeat.castorlive.sample.model.Author"

                     @castor.field-sql name="author"

                     @castor.field-xml name="author" node="element"

                     </documentation>

                 </annotation>

             </element>

I haven't gotten this completely working yet. I still need to finish

this because I want to include this in the Castor Live book.

As a side note, just this morning I hit a point where I need to

extend the Castor support in XDoclet so that it covers everything

in the mapping descriptor. The current version of XDoclet only

supports Castor JDO, it doesn't support Castor XML.
