Obtain assets from KnowledgeBase

marnold Jan 10, 2012 12:26 PM

I have stored some files in my Guvnor repository - just plain files, not model, rules or processes. I would like to obtain them programmatically for a particular package snapshot.

I am already loading my KnowledgeBase through a KnowledgeAgent, but this only appears to give me access to rules and processes (getRule(), getProcess()).

The Guvnor REST API doesn't seem to support snapshots. It has versions for each asset, but not snapshots.

Can anyone help or suggest alternatives? Thanks in advance.

You can use Guvnor's webdav access to get those files.

You could use the "old" Guvnor api to get this. At what point this may be deprecated I really don't know but works fine with Guvnor 5.3.1 which is used in jBPM 5.2. The URL for lets say my-image.png in package myPackage and snapshot LATEST would be:

http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/myPackage/LATEST/my-image.png

You should be able to substitute LATEST with your snapshot name.

Hope this helps.

Esteban,

Thanks - WebDAV works fine.

Tihomir,

Thanks for your suggestion. But I'd rather not use a deprecated API. And, FYI, unexpectedly, when I try to GET...

http://localhost:8080/guvnor/org.drools.guvnor.Guvnor/package/${package}/snapshot/${snapshot}/${filename}

... I always get the entire package in binary form - no matter what I put as ${filename} in the URL (using Guvnor 5.3.1). But this doesn't concern me. I will use WebDAV.

Thanks.

Hi Tihomir,

Is it possible to get the files from different versions of the package. Lets say, i have default package, and some files in that, and i update the files.

When i use them in my process i always get the latest files, is it possible to get files with different version other than latest?

Thanks
