Hi I am using two servlets, one to process CheckOut and the other to process Check In. I am currenlty using the CheckOutCheckInServiceThis is my code for CheckOutServletpackage com.xpflow.dam.poc.repository;import java.io.IOException;import java.io.InputStream;import java.io.OutputStream;import java

Hello,

I obtain the same exception (bad credentials) when I try to checkin a file but it's not in the same context. There is an extract of my code :


    private static void testCheckInFile(ServiceRegistry serviceRegistry) throws Exception{
        NodeService nodeService = serviceRegistry.getNodeService();

        // authenticate
        AuthenticationService authenticationService = serviceRegistry.getAuthenticationService();
        authenticationService.authenticate("admin", "admin".toCharArray());
        
        // get the store
        StoreRef storeRef = new StoreRef(
                StoreRef.PROTOCOL_WORKSPACE,
                "SpacesStore"
                );
        if (!nodeService.exists(storeRef))
        {
            return;
        }
        CheckOutCheckInService checkOutCheckInService= serviceRegistry.getCheckOutCheckInService();
        
        NodeRef companyHomeNode = getCompanyHome(nodeService, storeRef);
        
        if (companyHomeNode == null)return;
        
        NodeRef fileNodeRef = getNodeByPath(serviceRegistry, companyHomeNode, "testContent:testVersionedTextFile");
        if (fileNodeRef == null){
           System.out.println(" node created for versioned file not found");
        }
        else {
           System.out.println(" node created for versioned file found : " + fileNodeRef);
            Map<String, Serializable> versionProperties = new HashMap<String, Serializable>();
            versionProperties.put(Version.PROP_DESCRIPTION, "checkin made by test program");
            versionProperties.put(VersionModel.PROP_VERSION_TYPE, VersionType.MINOR);
            
           NodeRef workingCopy = checkOutCheckInService.getWorkingCopy(fileNodeRef);
           ContentData contentData;
           String contentUrl;
           contentData = (ContentData)nodeService.getProperty(workingCopy,ContentModel.PROP_CONTENT);
           contentUrl = contentData.getContentUrl();
           System.out.println("content Url :" + contentUrl);
           checkOutCheckInService.checkin(workingCopy, versionProperties, contentUrl );
        }                    
    }

This produce the following exception stack :

   Your problem is probably not related to the servlet environment. May be, the way we obtain the reference of the "workingCopy" is relevent : we both use the "getWorkingCopy" method. When you test the checkin in your checkoutServlet, you obtain the reference of the "workingCopy" as the result of the "checkout" method.

   I hope this will help. Of course, I am interested by the solution.

         Regards,

                    Andre

Hi

Make sure you use the pattern:

Authenticate …
try
{
stuff
}
finally
{
clear authentication
}

Post 1:
Seems to be another method that gives the problem??

Post 2:
I am not sure about mixing the JCR session with the Alfresco API.

An any case, there should be a security filter setting up authentication base on a ticket or redirecting for login.

BTW, you can use the authentication service to print out the name of the current user.

Regards

Andy

Hi,

I am sure the authentication is correct : I use the same pattern for this test than for other tests that work.

If I modifiy the "public-services-context.xml" file as it :


    <bean id="CheckoutCheckinService" class="org.springframework.aop.framework.ProxyFactoryBean">
       <property name="proxyInterfaces">
          <value>org.alfresco.service.cmr.coci.CheckOutCheckInService</value>
       </property>
       <property name="target"><ref bean="checkOutCheckInService"/></property>
       <property name="interceptorNames">
          <list>
              <idref local="CheckoutCheckinService_transaction" />
                <idref local="exceptionTranslator" />
                <!–  idref bean="CheckoutCheckinService_security" / commented by AWE –> 
             <idref local="CheckoutCheckinService_descriptor" />
          </list>
       </property>
    </bean>

‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Then my code works! I obtain the checkin of my node with correct information about the modifier (here it is made by "admin"). Maybe there is problem in the bean "CheckoutCheckinService_security".

Regards,

Andre

Hi

Please, consider this test. The following code works :


   private static void testCheckOutCheckInFile(ServiceRegistry serviceRegistry) throws Exception{
        NodeService nodeService = serviceRegistry.getNodeService();
        CheckOutCheckInService checkOutCheckInService= serviceRegistry.getCheckOutCheckInService();

        // authenticate
        AuthenticationService authenticationService = serviceRegistry.getAuthenticationService();
        authenticationService.authenticate("admin", "admin".toCharArray());
        
        // get the store
        StoreRef storeRef = new StoreRef(
                StoreRef.PROTOCOL_WORKSPACE,
                "SpacesStore"
                );
        if (!nodeService.exists(storeRef))
        {
            return;
        }
        
        NodeRef companyHomeNode = getCompanyHome(nodeService, storeRef);
        
        if (companyHomeNode == null)return;
        
        NodeRef fileNodeRef = getNodeByPath(serviceRegistry, companyHomeNode, "testContent:testVersionedTextFile");
        if (fileNodeRef == null){
           System.out.println(" node created for versioned file not found");
        }
        else {
           System.out.println(" node created for versioned file : " + fileNodeRef);
           NodeRef workingCopy = checkOutCheckInService.checkout(fileNodeRef);
           // workingCopy = checkOutCheckInService.getWorkingCopy(fileNodeRef);
           
            Map<String, Serializable> versionProperties = new HashMap<String, Serializable>();
            versionProperties.put(Version.PROP_DESCRIPTION, "checkin made by test program");
            versionProperties.put(VersionModel.PROP_VERSION_TYPE, VersionType.MAJOR);
           checkOutCheckInService.checkin(workingCopy, versionProperties);

        }                          
    }
    
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

but if I uncomment the line "// workingCopy = checkOutCheckInService.getWorkingCopy(fileNodeRef);", then I obtain the exception "Exception in thread "main" net.sf.acegisecurity.BadCredentialsException: Bad credentials presented
".

It seems that the "getWorkingCopy" method do not return a good reference.

More interesting : if I modify this code like this :


           System.out.println(" node created for versioned file : " + fileNodeRef);
           NodeRef workingCopy = checkOutCheckInService.checkout(fileNodeRef);
            NodeRef workingCopy2 = checkOutCheckInService.getWorkingCopy(fileNodeRef);
           if (workingCopy != workingCopy2){
              System.out.println("workingCopy != workingCopy2");
           }
           else {
              System.out.println("workingCopy == workingCopy2");
           }
            Map<String, Serializable> versionProperties = new HashMap<String, Serializable>();
            versionProperties.put(Version.PROP_DESCRIPTION, "checkin made by test program");
            versionProperties.put(VersionModel.PROP_VERSION_TYPE, VersionType.MAJOR);
           checkOutCheckInService.checkin(workingCopy, versionProperties);

‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I obtain the following output :


workingCopy != workingCopy2

   Notice that the exception occurs during the execution of the call to checkOutCheckInService.checkin(). Then it seems that the call to checkOutCheckInService.getWorkingCopy() will disturb the next (we do not use here the reference returned by getWorkingCopy as an argument to checkin).

Hi,

I still have the same problem : if I call "checkOutCheckInService.checkin()" after a call to "checkOutCheckInService.getWorkingCopy()", I obtain an exception : net.sf.acegisecurity.BadCredentialsException: Bad credentials presented during the excecution of "checkOutCheckInService.checkin()". It occurs even when I do not use the nodeRef returned by checkOutCheckInService.getWorkingCopy()".

There is an extract of my code. The problem occurs if I uncomment the call to "checkOutCheckInService.getWorkingCopy()". Of course, it's not usefull here but in real cases where we do not already have the reference of the "working copy".


          System.out.println(" node created for versioned file : " + fileNodeRef);
           NodeRef workingCopy = checkOutCheckInService.checkout(fileNodeRef);
           /* if I uncomment the following lines of code, I obtain an exception during the execution
            *   Exception in thread "main" net.sf.acegisecurity.BadCredentialsException: Bad credentials presented
               at ec.ep.dit.isp.sp.alfrescoeval.TestApiWithVisualChecks.testCheckOutCheckInFile(TestApiWithVisualChecks.java:812)
            *   (this is the line where I call the "checkin" method). 
            *
            NodeRef workingCopy2 = checkOutCheckInService.getWorkingCopy(fileNodeRef);
           if (!workingCopy.equals(workingCopy2)){
              System.out.println("workingCopy != workingCopy2");
           }
           else {
              System.out.println("workingCopy == workingCopy2");
           }
           */
            Map<String, Serializable> versionProperties = new HashMap<String, Serializable>();
            versionProperties.put(Version.PROP_DESCRIPTION, "checkin made by test program");
            versionProperties.put(VersionModel.PROP_VERSION_TYPE, VersionType.MAJOR);
           checkOutCheckInService.checkin(workingCopy, versionProperties);
