Error while finding folder in repository

[knkpchari]

Hi All,

When i am trying to find the folder details in repository using below code i am getting error which is a number changing every time. How to solve can any one help me in this.

public String DISCOVERY_SERVICE_WSDL_LOCATION = "/alfresco/cmisws/DiscoveryService?wsdl";
public final static QName DISCOVERY_SERVICE_NAME = new QName("http://docs.oasis-open.org/ns/cmis/ws/200908/", "DiscoveryService");

query.setStatement("select * from cmis:folder where cmis:name LIKE '"+reg_id+"'");
QueryResponse queryresponse=null;
try{
    queryresponse = disvcoveryServicePort.query(query);
}catch(CmisException ex){
    System.out.println("The value of exception ::::::::::::"+ex.getMessage());
    ex.printStackTrace();
}
‍‍‍‍‍‍‍‍‍‍‍‍‍

I am using Alfresco4.0. The above code is working fine in alfresco3.4.

It is not recommended to call disvcoveryServicePort directly ,you can use opencmis api instead.

hi,
Thanks for you reply. Can you please suggest some material on this as in am not getting equivakent for navigation service.

For query,you can use apache chemistry opencmis client and execute cmis query like following,

String url= "http://localhost:8080/alfresco/api/-default-/public/cmis/versions/1.1/atom"; //for 1.1
//String url= "http://localhost:8080/alfresco/api/-default-/public/cmis/versions/1.0/atom"; //for 1.0
      SessionFactory sessionFactory = SessionFactoryImpl.newInstance();
      Map<String, String> params = new HashMap<String, String>();
      params.put(SessionParameter.USER, "admin");
      params.put(SessionParameter.PASSWORD, "admin");
      params.put(SessionParameter.ATOMPUB_URL, url);
      params.put(SessionParameter.BINDING_TYPE, BindingType.ATOMPUB.value());
      params.put(SessionParameter.OBJECT_FACTORY_CLASS,
            "org.alfresco.cmis.client.impl.AlfrescoObjectFactoryImpl");
      List<Repository> repos = sessionFactory.getRepositories(params);
      if (repos.isEmpty()) {
         throw new RuntimeException("Server has no repositories!");
      }

      Session session = repos.get(0).createSession();
      ItemIterable<QueryResult> qrs = session.query("select * from cmis:folder where cmis:name LIKE '"+reg_id+"'", false);
      for(QueryResult q : qrs) {

      }
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

For navigation,you can use getObject()/getObjectByPath() method of Session class and combine getDescendants/getChildren method of Folder class
or You just get navigation service from binding and use it directly,like following:

 
session.getBinding().getNavigationService()

Thanks kaynezhang your reply really support me. I had followed the url for cmis
https://github.com/jpotts/alfresco-developer-series/blob/master/content/content-tutorial-cmis/src/ma...

downloaded cmis from :
http://chemistry.apache.org/java/download.html

Where as in my alfresco i am getting error for
Cannot access WSDL: http://localhost:9080/chemistry/browser/RepositoryService

can you  please sugget what might be the problem or how to publish this now.

Hi,
After changing the url for webservice i am getting error as below:

Changed url : parameter.put(SessionParameter.WEBSERVICES_ACL_SERVICE, serviceUrl + "/ACLService?wsdl");

Error is occurred when i am calling
session = factory.createSession(parameter);
<blockcode>19:17:55,617 ERROR [STDERR] Caused by: java.lang.ClassCastException: $Proxy456 cannot be cast to com.sun.xml.ws.developer.WSBindingProvider

[kaynezhang]

What bindding are you using? you are using browser binding? why do you provide a url like

http://localhost:9080/chemistry/browser/RepositoryService‍

Please paste your code here.

[knkpchari]

I am using webservice binding

SessionFactory factory = SessionFactoryImpl.newInstance();
        Map<String, String> parameter = new HashMap<String, String>();
        serviceUrl=alfrescoURL+"/alfresco/cmis";
        // user credentials
        parameter.put(SessionParameter.USER, cmsUser);
        parameter.put(SessionParameter.PASSWORD, cmsPassword);

        
        parameter.put(SessionParameter.BINDING_TYPE, BindingType.WEBSERVICES.value());
        parameter.put(SessionParameter.WEBSERVICES_ACL_SERVICE, serviceUrl + "/ACLService?wsdl");
        parameter.put(SessionParameter.WEBSERVICES_DISCOVERY_SERVICE, serviceUrl + "/DiscoveryService?wsdl");
        parameter.put(SessionParameter.WEBSERVICES_MULTIFILING_SERVICE, serviceUrl + "/MultiFilingService?wsdl");
        parameter.put(SessionParameter.WEBSERVICES_NAVIGATION_SERVICE, serviceUrl + "/NavigationService?wsdl");
        parameter.put(SessionParameter.WEBSERVICES_OBJECT_SERVICE, serviceUrl + "/ObjectService?wsdl");
        parameter.put(SessionParameter.WEBSERVICES_POLICY_SERVICE, serviceUrl + "/PolicyService?wsdl");
        parameter.put(SessionParameter.WEBSERVICES_RELATIONSHIP_SERVICE, serviceUrl + "/RelationshipService?wsdl");
        parameter.put(SessionParameter.WEBSERVICES_REPOSITORY_SERVICE, serviceUrl + "/RepositoryService?wsdl");
        parameter.put(SessionParameter.WEBSERVICES_VERSIONING_SERVICE, serviceUrl + "/VersioningService?wsdl");
        parameter.put(SessionParameter.REPOSITORY_ID, repositoryId);
        
        session = factory.createSession(parameter);
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

i am getting the error as shown above…kindly let me know how to get session object.

Following is sample code ,please write it like this

   public static String webservicesUrl="http://localhost:8080/alfresco/cmisws/";
   public static String username="admin";
   public static String password="admin";
   public static Session getSession()

   {

      SessionFactory sessionFactory = SessionFactoryImpl.newInstance();
      Map<String, String> parameter = new HashMap<String, String>();
      parameter.put(SessionParameter.USER, username);
      parameter.put(SessionParameter.PASSWORD, password);
        final String BINDING_TYPE = BindingType.WEBSERVICES.value();
        parameter.put(SessionParameter.BINDING_TYPE, BINDING_TYPE);
        parameter.put(SessionParameter.WEBSERVICES_ACL_SERVICE, webservicesUrl + "/ACLService?wsdl");
        parameter.put(SessionParameter.WEBSERVICES_DISCOVERY_SERVICE, webservicesUrl + "/DiscoveryService?wsdl");
        parameter.put(SessionParameter.WEBSERVICES_MULTIFILING_SERVICE, webservicesUrl + "/MultiFilingService?wsdl");
        parameter.put(SessionParameter.WEBSERVICES_NAVIGATION_SERVICE, webservicesUrl + "/NavigationService?wsdl");
        parameter.put(SessionParameter.WEBSERVICES_OBJECT_SERVICE, webservicesUrl + "/ObjectService?wsdl");
        parameter.put(SessionParameter.WEBSERVICES_POLICY_SERVICE, webservicesUrl + "/PolicyService?wsdl");
        parameter.put(SessionParameter.WEBSERVICES_RELATIONSHIP_SERVICE, webservicesUrl + "/RelationshipService?wsdl");
        parameter.put(SessionParameter.WEBSERVICES_REPOSITORY_SERVICE, webservicesUrl + "/RepositoryService?wsdl");
        parameter.put(SessionParameter.WEBSERVICES_VERSIONING_SERVICE, webservicesUrl + "/VersioningService?wsdl");

        
        parameter.put(SessionParameter.OBJECT_FACTORY_CLASS,
            "org.alfresco.cmis.client.impl.AlfrescoObjectFactoryImpl");
      List<Repository> repos = sessionFactory.getRepositories(parameter);
      if (repos.isEmpty()) {
         throw new RuntimeException("Server has no repositories!");
      }

      return repos.get(0).createSession();
   }

Hi kaynezhang,

After changing url for webservice to
http://localhost:8080/alfresco/cmisws/NavigationService?wsdl
Stil i am getting error at
List<Repository> repos = factory.getRepositories(parameter);
Is there any problem with alfresco 4.0 with cmis.

Please suggest what should i do for getting session so that i can create a folder.
My initial code is in alfresco3.4d with direct web services which is working fine, same code is not working for me on alfresco4.0 so i changed to cmis.
