An object can only have one object type. You can attach multiple aspects types, though. Is that what you want to do? You haven't defined an aspect type in your XML.

I appreciate your help since I am new to all this and am struggling with the whole concept. What I am trying to do is attach multiple files to a content type and I am not sure if I am doing the XML correctly, here is my last attempt. I have modified the XML but probably need a little help there along with a code hint. Here is my new XML:


<type name="hs:IdeaContent">
  <title>Hotel Solution Idea Content</title>
  <parent>cm:content</parent>
  <properties>

  <property name="hs:name">
    <type>d:text</type>
  </property>

  <property name="hs:hotel">
    <type>d:text</type>
  </property>

  <property name="hs:title">
    <type>d:text</type>
  </property>

  <property name="hs:attach1">
    <type>d:content</type>
  </property>

  <property name="hs:attach2">
    <type>d:content</type>
  </property>
</properties>
<associations/>
</type>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

So I am probably doing something wrong with the XML but I just want to attach say in attach1 a word document and attach2 a pdf document, etc. There will be a maximum of 5 attachments. I understand that Alfresco does not allow multiple attachments. The original XML was trying to set up a second <type> that would allow me to have some attributes around an attachment but I seem to be failing in both respects. I am able to create the content or create a document but my trouble is adding attachments to the content. Maybe I am crazy trying to do this but that's what the business wants :-). I really like the OpenCMIS API but am struggling a little bit since I am new to Alfresco and CMS in general and definitely OpenCMIS.

Regards,

John

CMIS only supports one content stream per document object. (It supports multiple renditions per document, but that's a different story.)
So you have to create multiple objects.

Since I don't know your application I can't tell you what would be the best way to set up your model. Here are a few ideas:

Create a folder, add your properties to that folder object and put all related documents into this folder.

Create a relationship type and connect all related documents with relationships.

Find a common key and add it all documents. Then you can find all related documents with a query.

Thanks for the suggestion. I am trying that now but getting an internal server error when I create the relationship between the Custom Content Type and any document. My code is as follows:


      Document document1 = null;
      Document document2 = null;
      ContentStream content = null;
      String path = null;
      Folder folder1 = null;
      Folder folder2 = null;
      
      try {
         //First get the folders we are working with
         session = createSession();
         
         path = "/User Homes/Ideas/";
         folder1 = (Folder) session.getObjectByPath(path);
         assertNotNull(folder1);
         String id = folder1.getId();
         assertNotNull(id);

When I run this code extrapolated from the OpenCMIS test suite it works fine:


         String path = "/User Homes/Ideas/Idea Documents";
         Folder folder = (Folder) session.getObjectByPath(path);
         assertNotNull(folder);
         String id = folder.getId();
         assertNotNull(id);
         System.out.println("ID = " + id);
   
           Map<String,String> newDocProps1 = new HashMap<String, String>();
           newDocProps1.put(PropertyIds.OBJECT_TYPE_ID, "D:cmiscustom:document");
           newDocProps1.put(PropertyIds.NAME, "Test Doc 1");
           ContentStream contentStream1 = new ContentStreamImpl("xyz.txt", null, "plain/text", new ByteArrayInputStream("some content".getBytes()));
           Document doc1 = folder.createDocument(newDocProps1, contentStream1, VersioningState.MAJOR, null, null, null, session.getDefaultContext());
   
           Map<String,String> newDocProps2 = new HashMap<String, String>();
           newDocProps2.put(PropertyIds.OBJECT_TYPE_ID, "D:cmiscustom:document");
           newDocProps2.put(PropertyIds.NAME, "Test Doc 2");
           ContentStream contentStream2 = new ContentStreamImpl("xyz.txt", null, "plain/text", new ByteArrayInputStream("some content".getBytes()));
           Document doc2 = folder.createDocument(newDocProps2, contentStream2, VersioningState.MAJOR, null, null, null, session.getDefaultContext());
           
           Map<String, Serializable> relProps = new HashMap<String, Serializable>();

Is there an issue with the custom content type having a relationship to a document? It seems to work when I use 2 documents. I have learned allot by tinkering with your replies and am getting closer to my goal each time. I can now create the custom content, documents, folders, etc. with no problem. Your help has been appreciated :-).

I'm not very clear about your requirement .
You can try to attach a foder to your workflow,and add your attached files to this folder.
