If you need to generate DCRs from the command line, before, with the perl templates, we could use iwgen, iwregen, iwpt_compile to do our work for us. Now, we can’t because these tools do not support the XSL presentations we want to give them.

So, to paliate to this lack, we can create a class that’s going to do it from the command line.

 The engine behind all this is Xalan, so we can call it via the command line like this:

java org.apache.xalan.xslt.Process -IN absoluteDCRPath  -XSL absoluteXSLPath -OUT outputfilePath

However, this does not create the extended attributes we require. For this, you will need to connect ot teamsite, acquire the file and set the attributes that are required. This class below opens the DCR, transforms it using the XSL and sets the extended attributes as required.
