Excel POI problem when starting connector

[Andreas Grünwald]

Hello guys,

Kristof told me a few month ago that the CDL-Flex bus is using Apache POI for reading and writing Excel files. I created a connector which is using Apache POI and tried to start the bundle, but received a wiring exception (see below).

I guess the reason is that I have to start the POI bundle which is not contained by default? Where can I find the bundle and how do I install it? I searched in the Artifactory for it, but couldn't find a bundled version of the poi library (only jar)? With the available package it does not work.

Please tell me that I don't have to bundle it by myself, because this will take me another two days I guess :-/

Best regards and thank you very much,

Andreas

Hey Andreas,

Are you sure you're hitting the right list? Especially if you're after some closed source developed components :-)

Kind regards,

Andreas
