Hi all,
I recorded a screencast which demos how to use a custom utility class in the Data Mapper.

Enjoy,
Robin

Hi Robin
Thanks for your video. It seems it is impossible to watch the video with full size.
Best regards

Hi,
This is a great video. I created my jar file and can call the java method in my map thanks to video explanations.
On the other hand the video describes a map call from a route with cMap.
I want to do a map call from a job (And not a route) with a tHmap component. What do I have to do so that my job knows my new jar ?
I added a tLibraryLoad to start the job and it works fine but isn't there a way to avoid adding this component in all the jobs using this external jar file ?
I tried to add my jar file in the module view but it didn't work...
I also tried to add it in "Preferences->Java->Build Path->User Libraries" but it didn't work either...
Thanks for your help.
Eric

Hi
Create a routine and import the external jar, call the routine in the job if requires, by default, the job will be dependency with all routines.

Hi Shong,
Thanks for your answer, but in a map of TDM we cannot call a routine.
