[rules-users] Upload an existing .drl for the Guvnor dynamically

Is it possible to retrieve all rules within a category via the Rest API 
(or some other means) ?

Thanks

Hi Dirk,

You could also try using the existing remote API with Guvnor to push up 
new content to the server.

Try: 

1. GET 
http://servername:port//org.drools.guvnor.Guvnor/api/packages/{packageName}

To pull the list of assets from the Guvnor API for a specific package.

2.  You can POST a DRL using the existing rest api like so.

A) Create a post request to "
http://servername:port//org.drools.guvnor.Guvnor/api/packages/{YourPackageName}/{YourAssetName}
"

e.g., POST h
ttp://servername:port//org.drools.guvnor.Guvnor/api/packages/{YourPackageName}/{YourAssetName}

B) Append your file data to the POST request as part of the request (as 
you would with a POST'ed file upload).

"REST" based calls are handled through two classes:

org.drools.guvnor.server.filesRestAPIServlet
(in the drools-guvnor module)

and

org.drools.repository.remoteapi.RestAPI
(in the drools-repository module).

3.  PUT calls handle updates to existing resources on the server, in a 
similar way, with DELETE allowing removal of resources. 

4.  In terms of WebDAV, JCR also has a nice WEBDAV client implementation 
available that extends Apache's httpclient, but with some WEBDAV specific 
support built in. 

The RestAPI class in Drools-Repository has some very good detail on how 
this process works, and I'd suggest looking there if you have questions 
(on the REST API side).

There is some discussion about REST, as well, currently on the dev mailing 
list if you search Nabble.

A few ideas,

Andrew

Hi!

I would like to accomplish the same thing. Is there really no programmatic
way to do this?
I noticed that the files are uploaded through the eclipse-plugin using
webdav. Is it documented
what has to be done in order to install/update a drl using webdav?

Thx,
Dirk
