Writing into DCR using CSSDK

Jeya

Hi All,
Working with TeamSite 7.2.1.0.0. I am working on a requirement where i have to update thousands of DCRs with the data retrieved from an external DB in a click event.We are using CSSDK. Below is the approach i can think of.
1. Retrieve the data, dump in a collection
2. Get the DCR, conver it to a DOM object, update it with DB data.
3.Convert the DOM to byte array
4.Write back using CSSimpleFile.write() which takes byte[] as a param.

I would like to know if there is any better way to do this. Does CSSimplFile have any other method which I could use? I see a getOutputStream.

"java.io.OutputStream getOutputStream(boolean threadSafe)
Gets the output stream to write to the SimpleFile "
Any idea how to use this?

CSSimpleFile.getOutputStream() is the method I'd recommend. I can attest to the fact that it works. Note that in a previous version (7.1 I think it was), there was some oddity with finding non-visible whitespace characters in front of the XML declaration when reading DCRs with CSSimpleFile.getInputStream(), so be aware that you may need to clean up the String a bit before feeding it to a DOM parser.

That whole "in a click event" piece would make me very nervous in terms of file locks and concurrent changes though. I suggest executing this process in a separate workarea and/or creating editions of the content and/or doing something smart with file locks, before running such a potentially destructive process. Just a thought.
