[rules-users] Drools library - updating Drools jar

[Pegram, Macon]

There's another way.....

 

In the Eclipse Plugin Preferences (Eclipse -> Preferences -> Drools ->
Installed Drools Runtime) you point to the location of the Drools
runtime you want to use.  If you swap out the MVEL file at the location
of your Drools Runtime it should pick up the right version of the MVEL. 

 

You could also duplicate the jar files in that folder into a "Patch"
folder, replace the MVEL jar in the PATCH copy, and setup a "Patch
Drools Runtime" if you want to keep your original installation pristine.

 

You will likely need/want to bounce Eclipse for this to take effect.

   Does not matter the order in the "libraries" tab. You need to set
them in the "Order and Export" tab.

Edson thank you very much for your suggestions.

I wonder if it didn't work because I used 2.0.13? - I did that because I
couldn't find 2.0.12 on the download page at
http://docs.codehaus.org/display/MVEL/Downloading+MVEL - as you can see
from
the attached pic I did try adding that jar to the project build path,
ahead
of the "standard" Drools library.

I'll download 2.0.14-SNAPSHOT and try it with that. Don't have the
strength
to rebuild etc right now! I'll report back. Thanks again for your help,
much
appreciated. :)
