Getting AuthenticationService in ActionHandler

dynamolalit — Tue, 13 Apr 2010 12:02:29 GMT

Hi,I am using Alfresco 3.2r with Tomcat 6.I have written a workflow in which i am tyring to move a document from one space to another using ActionHandler.I am calling my ActionHandler from WF as<node name="approved"> <event type="node-leave"> <script>

I don't get why you're trying to get the implementation class, or why using the authenticationService when the code is being executed inside alfresco, better use the AuthenticationUtil.runAs() , this way you won't need to include the password in your class, and avoid the whole problem with getting AuthenticationServiceImpl.


public void execute(ExecutionContext context) throws Exception {


 AuthenticationUtil.runAs(new AuthenticationUtil.RunAsWork<Object>() {

            public Object doWork() throws Exception {

logger.debug("Inside execute of KMReviewProcessAction logger@@@");
      System.out.println("Inside execute of KMReviewProcessActionsyso");
      // authserv.authenticate("admin", "admin".toCharArray());
      ContextInstance contextInstance = context.getContextInstance();
      String wfFlag = (String) contextInstance.getVariable("wfFlag");
      logger.debug("wfFlag in  KMReviewProcessAction logger @!@!" + wfFlag);
      System.out.println("wfFlag in  KMReviewProcessAction syso" + wfFlag);
      if (wfFlag.equalsIgnoreCase("Approved")) {
         // to do for approval!!
         String password = "km@jindal!";
         authenticationServiceImpl.authenticate("jindaladmin", password.toCharArray());      
         StoreRef storeRef = new StoreRef(StoreRef.PROTOCOL_WORKSPACE,
               "SpacesStore");
         System.out.println("searchService  " + searchService);
         ResultSet rs = searchService.query(storeRef,
               SearchService.LANGUAGE_XPATH, "/app:company_home");
         NodeRef companyHomeNodeRef = null;
         try {
            if (rs.length() == 0) {
               throw new AlfrescoRuntimeException(
                     "Didn't find Company Home");
            }
            companyHomeNodeRef = rs.getNodeRef(0);
         } catch (Exception e) {
            logger.error("Error while getting company home "
                  + e.getMessage());
         }
         List<ChildAssociationRef> children = nodeservice
               .getChildAssocs(companyHomeNodeRef);
         for (ChildAssociationRef childAssoc : children) {
            NodeRef childNodeRef = childAssoc.getChildRef();
         System.out.println("childNodeRef inside  execute  " + " " + childNodeRef.getId()
                  + childNodeRef.getStoreRef());

         }
      }

},    AuthenticationUtil.getSystemUserName()     };
}

if the problem with authenticationService was the only thing preventing your code from working it should be solved now.
Hope it helps.

PS: if you check the runtime class of AuthenticationService returned by serviceRegistry isn't neccessarily AuthenticationServiceImpl, but a proxy class returned by static method of "java.lang.reflect.Proxy", thats why you should always stick to using the interface and not the the implementation.

Hi Sohaib,

Thanks for your reply.

I tried the approach you suggested.Still my problem persists.Here is my code:

public void execute(ExecutionContext context) throws Exception {
      System.out.println("Inside execute of KMReviewProcessAction");
      final ContextInstance contextInstance = context.getContextInstance();
      String systemUserName = AuthenticationUtil.getSystemUserName();
      System.out.println("systemUserName "+systemUserName);
      AuthenticationUtil.runAs(new AuthenticationUtil.RunAsWork<Object>() {
      String wfFlag = (String) contextInstance.getVariable("wfFlag");   
      List<ChildAssociationRef> children = null;
         public Object doWork() throws Exception {
            System.out.println("wfFlag in  KMReviewProcessAction "+ wfFlag);            
            // authserv.authenticate("admin", "admin".toCharArray());            
            //logger.debug("wfFlag in  KMReviewProcessAction logger @!@!"+ wfFlag);            
            if (wfFlag.equalsIgnoreCase("Approved")) {
               // to do for approval!!
               String password = "km@jindal!";
               //authenticationServiceImpl.authenticate("jindaladmin",   password.toCharArray());
               StoreRef storeRef = new StoreRef(
                     StoreRef.PROTOCOL_WORKSPACE, "SpacesStore");
               System.out.println("searchService here !! " + searchService);
               ResultSet rs = searchService.query(storeRef,SearchService.LANGUAGE_XPATH, "/app:company_home");
               NodeRef companyHomeNodeRef = null;
               try {
                  if (rs.length() == 0) {
                     throw new AlfrescoRuntimeException(
                           "Didn't find Company Home");
                  }
                  companyHomeNodeRef = rs.getNodeRef(0);
               } catch (Exception e) {
                  logger.error("Error while getting company home "
                        + e.getMessage());
               }
               children = nodeservice
                     .getChildAssocs(companyHomeNodeRef);
               for (ChildAssociationRef childAssoc : children) {
                  NodeRef childNodeRef = childAssoc.getChildRef();
                  System.out.println("childNodeRef inside  execute  "
                        + " " + childNodeRef.getId()
                        + childNodeRef.getStoreRef());

               }
            }
            return children;
         }
      }, systemUserName);
   }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Its saying error is @ line no 108 as

at com.jindal.alfresco.km.bpm.KMReviewProcessAction$1.doWork(KMReviewProcessAction.java:108)

Which is

ResultSet rs = searchService.query(storeRef,SearchService.LANGUAGE_XPATH, "/app:company_home");

Means still its not able to get SearchService??

Re: Getting AuthenticationService in ActionHandler

dynamolalit — Fri, 16 Apr 2010 12:23:47 GMT

Hi,

What i got from my RnD is that Alfresco 3.2 will not allow you to get services directly the way i am trying.

As another approach , if you want to get a service say searchservice, you have to get it thru managed bean whose entry should be in faces-config-beans.xml with particular service as

<managed-property>
         <property-name>searchService</property-name>
         <value>#{SearchService}</value>
      </managed-property>

Now you can get it in your code.May be if you want to get services in Workflow ActionHandler, you may need to make it a managed bean. :roll:

May be I am not right fully. :idea:

Any ideas or comments?
