Esteban I too am trying to integrate the Rule editing widget into my web page. I followed your writeup, very helpful indeed. What is missing though is a handy method to get all rules under a category. In my app (and I suspect in most cases where people are trying to embed the asset editor), we only want to retrieve those rules that belong to the category that the web user has access to. There seems to be no way of doing this in the REST API or the service classes built on top of RulesRepository.

I am observing that RuleRepository object is coming as null. Note: Through the integrated app If I hit the Guvnor URL than it is working as normal. private ServiceImplementation getService() { ServiceImplementation impl = new ServiceImplementation(); RulesRepository repository = impl.getRulesRepository(); return impl; } What is the suggested way of using the Guvnor services from the jsp/java ? _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users ----------------------------------------- The information contained in this communication (including any attachments hereto) is confidential and is intended solely for the personal and confidential use of the individual or entity to whom it is addressed.

GPatel(a)tsys.com wrote: Hi Ghanshyam, Once the new JAX-RS based REST interface is in place (its not there yet, but will come in soon), you can use following ways to retrieve rules under a category. For example: A HTTP GET request to URL http://host:portnumber/repository/categories with Accept="application/atom+xml" returns a list of categories in the repository in Atom Feed format. A HTTP GET request to URL http://host:portnumber/repository/categories/testCategory1/assets with Accept="application/atom+xml" returns a list of assets under the testCategory1 in the repository in Atom feed format. A GET request to http://host:portnumber/repository/categories/testCategory1/assets/testAsset1 with Accept="application/atom+xml" returns an atom entry which is a summary info of that asset as well as its meta data. A GET request to http://host:portnumber/repository/categories/testCategory1/assets/testAsset1 with Accept="application/octet-stream" returns a binary attachment (if that asset has a binary attachment as content). A GET request to http://host:portnumber/repository/packages/testPackage1/assets/testAsset1 with Accept="application/source" returns the asset source in text format (if that asset has a content in text format). A GET request to http://host:portnumber/repository/packages/testPackage1/assets/testAsset1 with Accept="application/json" returns a json object which is the summary info of that asset as well as its meta data. Will this meet your requirement? Thanks, Jervis

Hello Esteban, Thanks for your invite to contribute. Actually I really like Drools and belive it has most of the things required for a successfull product. Right now(for 1.5 months) I cannot do main stream contribution but I promise that whatever I do to integrate or enhance Guvnor for our custom requirements I will make it available to all.. I hope the stuff I have done might be useful for somebody. For drools-guvnor users, primary purpose is to integrate it into their custom app.(if they don't want to deploy guvnor separately) 1. Merging of Guvnor into a cutsom app is not a very difficult tasks. One needs to copy all the Guvnor resources into the respective folders of the cutsomApp. Also the web.xml has to be updated with the Guvnor stuff. Note: My custom app was based on spring MVC. No GWT but it fits decently. 2. Authentication & Authorization: The general requirment would be to do authentication & authorization in the Guvnor based on the custom apps. Update the components.xml with customAuthenticator & role based permission as true. (There are other better ways to solve the problem like SSO, SAML but since I was able to merge the apps so I depended on the HttpSession.) silent authentication. The session can be accessed in your customAuthenticator by AdminContext authenticatedAdminInfo = (AdminContext)Contexts.getSessionContext().get("adminSession"); I have written a CustomIntegrator class which does the implicit package creation, assign role to a user on a package. RepositoryService instance can be created by (ServiceImplementation) Component.*getInstance*( "org.drools.guvnor.client.rpc.*RepositoryService*" ); RoleBasedPermissionStore instance can be created by RoleBasedPermissionStore store = (RoleBasedPermissionStore) Component.* getInstance*("org.drools.guvnor.server.security.RoleBasedPermissionStore"); store.addRoleBasedPermissionForTesting(userName, new RoleBasedPermission(userName, RoleTypes.PACKAGE_ADMIN, orgName, null)); ------------------------------------------------------------------------code snippet--------------------------------------------------------------------------------- package org.drools.sample; import javax.security.auth.Subject; import javax.security.auth.login.LoginException; import javax.servlet.http.HttpSession; import org.jboss.seam.annotations.Name; import org.jboss.seam.contexts.Contexts; import org.jboss.seam.security.Identity; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import com.sample.admin.framework.adminmgmt.PrincipalAdmin; import com.sample.admin.framework.policy.AdminContext; import com.sample.admin.framework.web.controller.AbstractCygnetController; @Name("sampleAuthenticator") public class SampleAuthenticator { private static final Logger log = LoggerFactory.getLogger( SampleAuthenticator.class ); /** * @param session * @return */ public boolean authenticate() { log.info( "User logged in via sample admin login module ."); AdminContext authenticatedAdminInfo = (AdminContext)Contexts.getSessionContext().get(AbstractCygnetController.SESSION_ADMIN_CONTEXT); if(authenticatedAdminInfo == null) return false;//no session available for the user PrincipalAdmin principalAdmin = authenticatedAdminInfo.getPrincipal(); if("ACTIVE".equalsIgnoreCase(principalAdmin.getAuthStatus())) { Identity.instance().getCredentials().setUsername( principalAdmin.getUserID() ); //CallbackHandler callbak = Identity.instance().getCredentials().createCallbackHandler(); //callbak.handle(callbacks); SamplePrincipal[] authPrincipals = new SamplePrincipal[3]; //Adding username to the subject authPrincipals[0] = new SamplePrincipal(principalAdmin.getUserID()); //Adding organization to the subject authPrincipals[1] = new SamplePrincipal(principalAdmin.getOrgName()); //Adding role to the subject authPrincipals[2] = new SamplePrincipal(principalAdmin.getRole().getName()); Subject subject = Identity.instance().getSubject(); for (int i = 0; i < authPrincipals.length; i++) { if(!subject.getPrincipals().contains(authPrincipals[i])) { subject.getPrincipals().add(authPrincipals[i]); } } return true; } return false; } /** * @param session * @return */ public boolean sessionAuthenticate(HttpSession session) { log.info( "User logged in via sample admin login module ."); //AdminContext authenticatedAdminInfo = (AdminContext)session.getAttribute("adminSession"); AdminContext authenticatedAdminInfo = (AdminContext) session.getAttribute(AbstractCygnetController.SESSION_ADMIN_CONTEXT); if(authenticatedAdminInfo == null) return false;//no session available for the user PrincipalAdmin principalAdmin = authenticatedAdminInfo.getPrincipal(); if("ACTIVE".equalsIgnoreCase(principalAdmin.getAuthStatus())) { Identity.instance().getCredentials().setUsername( principalAdmin.getUserID() ); //CallbackHandler callbak = Identity.instance().getCredentials().createCallbackHandler(); //callbak.handle(callbacks); SamplePrincipal[] authPrincipals = new SamplePrincipal[3]; //Adding username to the subject authPrincipals[0] = new SamplePrincipal(principalAdmin.getUserID()); //Adding organization to the subject authPrincipals[1] = new SamplePrincipal(principalAdmin.getOrgName()); //Adding role to the subject authPrincipals[2] = new SamplePrincipal(principalAdmin.getRole().getName()); Subject subject = Identity.instance().getSubject(); for (int i = 0; i < authPrincipals.length; i++) { if(!subject.getPrincipals().contains(authPrincipals[i])) { subject.getPrincipals().add(authPrincipals[i]); } } } try { Identity.instance().authenticate(); } catch ( LoginException e ) { log.error( "Unable to login.", e ); return false; } return Identity.instance().isLoggedIn(); } } 2010/12/23 Esteban Aliverti <esteban.aliverti(a)gmail.com&gt;
