Hi ,

i am encountering the same issue . i did add the versioning aspect to my file but still error is same.
i am performing steps :

1) generate 30 unique file names: mayank_0 , mayank_1….
2) create these files in alfresco repository ——– creation works fine.
3) try to recreate files —- search for any file with same name – delete the file – recreate..

code is :

       // create parent reference
         ParentReference companyHomeParent = new ParentReference(STORE, null,
                                                         "/app:company_home/cm:TaxPlanning", Constants.ASSOC_CONTAINS, "{" +
                                                         Constants.NAMESPACE_CONTENT_MODEL + "}" + "name");
         NamedValue[] contentProps = new NamedValue[3];
         NamedValue[] titledProps = new NamedValue[2];
         CML cml = new CML();
         Query query1 = new Query();
         for(String fileName : files){
          // Assign name to children
          companyHomeParent.setChildName("{http://www.alfresco.org/model/content/1.0}" + fileName);
          //
          ContentFormat contentFormat = new ContentFormat("Adobe PDF Document", "UTF-8");
          contentProps[0] = Utils.createNamedValue(Constants.PROP_NAME, fileName);
          contentProps[1] = Utils.createNamedValue(Constants.PROP_CONTENT,
                                                       ContentFormat.getMimetype());
          contentProps[2] = Utils.createNamedValue(Constants.PROP_USER_ORGID, customerId);
          //Construct CML statement to add titled aspect
          titledProps[0] = Utils.createNamedValue(Constants.PROP_TITLE, fileName);
          titledProps[1] = Utils.createNamedValue(Constants.PROP_DESCRIPTION, "Document for
                                                                                           customer");

          CMLAddAspect addAspect = new CMLAddAspect(Constants.ASPECT_VERSIONABLE, contentProps,
                         null, "1");
          // query to search for existing file with same name
          query1 = new Query(Constants.QUERY_LANG_LUCENE,
                                         "PATH:\"app:company_home/cm:TaxPlanning/cm:" + fileName + "\"");
          ResultSet rs =service.query(STORE, query1, false).getResultSet();
          // file already exist, then, delete it and create a new one
          if(rs.getTotalRowCount() > 0){
             System.out.println("file found ::" + fileName);
             ResultSetRow[] rsRows = rs.getRows();
             System.out.println("Removing file " + rsRows[0].getColumns(3).getValue()); //show file name
             Reference reference = new Reference(STORE, rsRows[0].getNode().getId(), null);
             System.out.println("removing reference" + rsRows[0].getNode().getId());
             Predicate predicate = new Predicate(new Reference[]{reference}, null, null);
             CMLDelete delete = new CMLDelete(predicate);
             cml.setDelete(new CMLDelete[] {delete});
             service.update(cml); ————— EXCEPTION COMES HERE – DUPLICATE CHILD NAME NOT
                                ALLOWED.
          }
          logger.log(Level.INFO, "creating new content from scratch");
          //create content
          // Construct CML statement to create content node
          // Note: Assign "1" as a local id, so we can refer to it in subsequent
          // CML statements within the same CML block
          CMLCreate create = new CMLCreate("1", companyHomeParent, companyHomeParent.getUuid(), Constants.ASSOC_CONTAINS, null, Constants.PROP_CONTENT, contentProps);
          // Construct CML Block
          cml = new CML();
          cml.setAddAspect(new CMLAddAspect[] {addAspect});
          cml.setCreate(new CMLCreate[] {create});
          // Issue CML statement via Repository Web Service and retrieve result
          // Note: Batching of multiple statements into a single web call
          UpdateResult[] result = service.update(cml);
          Reference content = result[0].getDestination();

Hi mayank

I didn't go through your code. I think you didn't use checkout/checkin concept here . Just Follow these steps which i am using—

1: get your file Reference object inwhich you want to add versioning aspect and repositoryService object like this–
RepositoryServiceSoapBindingStub repositoryService = WebServiceFactory.getRepositoryService();

2: pass this file Reference object and repositoryService object to makeVersionable method–
makeVersionable(RepositoryServiceSoapBindingStub repositoryService, Reference fileRef);

3: then checkout the file. When you will do checkout then Alfresco will create a working copy of the original file

4: get the working copy Reference

5: get the Input stream from the file object and pass this object to convertToByteArray method like this—-
byte[] bytes=ContentUtils.convertToByteArray(stream);

6:then update the content of the working copy using contentService.write(—)

7: then checkin

Hope it'll help.
