In principle I am guessing one should be able to start with an xsd file Generate the Code using the Source Code generator with the option of not creating the descriptor files. Use the MappingTool using the Top level Class or Element to generate a mapping file and then in turn use this as the mapping file during the unmarshalling and marshalling process.
Well what I am noticing is that the Mapping tool does include all the "valid=true" and <array>-total attributes however it does not add any of the "extends= " attributes in the mapping file. So I am guessing this is a Bug I should file against the Mapping Tool. What I am kind of almost doing is a circular self reference check. Finally, I find out that by adding the extends attribute to the class element and properly adding all the elements did solve the problem. It is though a bit tricky cause I am now perplexed as to the case of my own more complicated project. Here I am not able to get this to work properly. I would say that it would really help if the Mapping tool could add in the proper extend statements. Thanks -----Original Message----- From: Keith Visco [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 17, 2003 3:13 PM To: [EMAIL PROTECTED] Subject: Re: [castor-dev] SrcCode Generator Marshaller adding extra fields when using a Mapping File Gerald, If you're getting the extra attributes, that means Castor was unable to find the proper mapping for the respective object in the mapping file and reverting to default introspection of the object's class to automatically create a mapping. Normally when this happens it's because the user was using one of the static marshal methods and therefore the non-static mapping was inaccessible. But this is not what's happening in your case as your code is not using the static marshal method. Without having run your example, I can only venture a guess. It's most likely due to inheritence. For example, your concrete class appears to be com.u2d.ship.Shipper, but your mapped class appears to be com.u2d.shipgen.Shipper. This is why Castor adds the "xsi:type" attributes in your output, so that it can know the proper instance during unmarshalling. Castor is probably getting hung up on the inheritence and introspecting the com.u2d.ship.Shipper class , and unfortunately including superclass attributes that it shouldn't be including. This would definately be a bug if that's the case. A simple workaround would be the following to prevent this additional introspection: Add the following to your mapping file: <class name="com.u2d.ship.Shipper" extends="com.u2d.shipgen.Shipper"/> That should solve the problem. You might also want to file this as a bug in our bugzilla database (http://bugzilla.exolab.org), if that's indeed what is happening. Thanks, --Keith > "Gerald E.
