Subject Re: initiating CpeComponentDescriptor from String or InputStream
Date Fri, 09 Sep 2016 15:34:50 GMT

That's also the solution I can think of: getting the descriptor contents
from the database and save them as temp files. Then use those temp files to
initiate the cas processors.

Best,
Xiaobin
