I am also confusing on this point: I have been trying to create a PolicyStore class containing a collection of policy objects.
1) First I used xsd directly to generate src via srcGenerator. However it create a array of policy objects in policyStore by default, while I need hashMap as container for policies so that I can query by key. 2) Then I created a mapping file by using O2XMapper and tried to use this mapping file to redefine the container as Map. 3) I looked around srcGenerator cmd option and found a option named "binding-file". I took for granted thought it should be mapping file. The result was that srcGenerator refused to accept mapping file and threw exception 4) I realize that binding file must be new feature (I couldn't find this option in castor0.9.3) My question is if there is a way to generate source by using mapping file as fine-grain control? If not, is there a tool to generate binding file automatically? ~Bin --- Stephen Bash <[EMAIL PROTECTED]> wrote: > Barbara- > > I'm not much of an expert on the binding-file side, > but I use mapping > files all the time.
