How to delete existing BPMN processes from guvnor programatically

[bulejava]

right click 

then hover  menu named "Gvnor" click  "delete"

if you want to delete it thorough,then you have to  open http://loclahost:8080/drools-guvnor

left menu  Administrator  Archive

you can delete them from the table

From the Java  Program how can I delete the particular selected process.

For example, I have a Delete button on the JSF web page when I submit it, should delete the selected process.

Please suggest

You have to use the Guvnor REST API, more info in the docs: http://docs.jboss.org/drools/release/5.3.0.Beta1/drools-guvnor-docs/html_single/index.html#d0e1680.

Hope this helps.

Thanks for the reply Tihomir.

I added cxf-bundle-jaxrs.2.3.0.jar and droolsjbpm-ide-common.5.3.0.jar to the project classpath. I am always getting the following error when creating instance of WebClient.create("http://127.0.0.1:8080/")

Code Segment which I am using to delete:

WebClient client = WebClient.create(http://127.0.0.1:8080/); //Getting error in this line only

Response response =client.path("/drools-guvnor/rest/packages/SDS/assets/assetName").accept("application/xml"

).delete();

Error

java.lang.AbstractMethodError: javax.ws.rs.core.UriBuilder.encode(Z)Ljavax/ws/rs/core/UriBuilder;

I tried googling for the compatible jar version, those are giving different errors. Can you please suggest the compatible jar

Guvnor contains cxf jars version 2.4.1, maybe that will help to use the same ones as what's in Guvnor already (in /WEB-INF/lib). I have used so far only standard HttpUrlConnection which has worked fine.

[uvijayreddy657]

I tried using HttpURLConnection to delete the process using the following code as WebClient is always giving me the UriBuilder error. But it is not deleting the process. Can you please suggest whether this works or not/ any modifactions required  for deleting asset

URL url = new URL(guvnorRepoURL

                     + "/drools-guvnor/rest/packages/SDS/assets/"

                     + asset.getName());

connection = (HttpURLConnection) url.openConnection();

connection.setRequestMethod("DELETE");

connection

                     .setRequestProperty(

                     "User-Agent",

                     "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.2.16) Gecko/20110319 Firefox/3.6.16");

connection

                     .setRequestProperty("Accept",3

                     "text/html,application/xhtml+xml,application/xml;q=0.9,*;q=0.8");

connection.setRequestProperty("Accept-Language",

                     "en-us,en;q=0.5");

connection.setRequestProperty("Accept-Encoding",

                     "gzip,deflate");

connection.setRequestProperty("charset", "UTF-8");

connection.setReadTimeout(5 * 60 * 1000);

connection.connect();

Hi you can see some specific examples here: https://github.com/tsurdilo/process-designer/blob/master/src/main/java/com/intalio/web/server/TaskFormsServlet.java , https://github.com/tsurdilo/process-designer/blob/master/src/main/java/com/intalio/web/server/TransformerServlet.java , and here: https://github.com/droolsjbpm/jbpm/blob/master/jbpm-gwt/jbpm-gwt-shared/src/main/java/org/jbpm/integration/console/shared/GuvnorConnectionUtils.java

For deleting assets here is an example:

String deleteURL = ExternalInfo.getExternalProtocol(profile)

                    + "://"

                    + ExternalInfo.getExternalHost(profile)

                    + "/"

                    + profile.getExternalLoadURLSubdomain().substring(0,

                            profile.getExternalLoadURLSubdomain().indexOf("/"))

                    + "/rest/packages/" + packageName + "/assets/" + assetName

                    + assetExt;

URL deleteAssetURL = new URL(deleteURL);

                HttpURLConnection deleteConnection = (HttpURLConnection) deleteAssetURL

                        .openConnection();

                applyAuth(profile, deleteConnection);

                deleteConnection.setRequestMethod("DELETE");

                deleteConnection.connect();

                _logger.info("delete connection response code: " + deleteConnection.getResponseCode());

If have set up authentication in Guvnor, the applyAuth method sets the Basic Authorization header with the encoded username and password.

Hope this helps.

Thanks for the reply Tihomir.

The code fragment which you posted is almost same what I posted in my previous one. However this code is not deleting the process from Guvnor repository.

[tsurdilovic]

>> However this code is not deleting the process from Guvnor repository. << Then something else is wrong, and you should try to debug and look at the logs. What Guvnor version are you using?

[uvijayreddy657]

I replaced jar jsr311-api-1.0.jar to  jsr311-api-1.1.1.jar solved the URIBuilder Error Issue. Now I am able to delete the process from the guvnor repository using the following code snippet.

WebClient client = WebClient.create("http://localhost:8080/drools-guvnor/rest/packages/SDS/assets/"+ asset.getName(), "admin", "admin", null);

Response response = client.delete();

I hope this would help someone.

Thanks.
