Gao,
the best way I think is to use slides event mechanics. You can implement a ContentListener. This listener can create the new property in the create method which is called if a new resource is created.
So you don't need to change slides code (:-)
Have a look in the package org.apacha.slide.event.
Listeners are registered in the Domain.xml, you can find samples in the default Domain.xml i think.
Hope, this helps Stefan

Hi everybody,
I have a question on using slide. We want to add one more internal property - "nodeId" to each node of slide. This property should be managed (set the value) inside of the slide server, just like other properties like displayname, getcontentlength, etc, so that when users, with any webdav client, upload a file to slide server, the file's "nodeId" property value can be set by slide server automatically - it will be a sequence no actually. My question is How could I achieve this by modifying slide code as clean as I can?
Which part of the slide code (or which class) should I go to modify? Is it in StructureImpl?
Is there some Factory pattern which I can take use of so that I can apply my
changes by extending some interface or abstract class instead of changing slide's code directly?
Is there anyone who has done similar things before? Thanks in advance for all the advices and suggestions.
regards,
Jun
