Hi,

1. I have been exploring Alfresco for programmatic data retrieval to & fro from Alfresco Repository and finding it really interesting and I think I am going to decide to go with Alfresco in production as well.
2. I was able to setup Alfresco and am able to create spaces, folders, files, upload docs, versioning, etc. but stuck at one point.
3. I am not able to create relationship between two files.

My model looks like this:
<ul><li> I have two folders(HTMLs) & (Images). Tons of files are inserted inside images folder and small part of business use case I am trying to implement is that when client asks for say chapter1.html then all the associated images to that chapter1.html should be fetched from the Repository and sent.
</li></ul>

– I am using CMIS and able to do most of the stuff that it provides. I have gone through most of the tutorials and code snippets and could create the relationship in this way:

https://anonsvn.springframework.org/svn/se-surf/branches/DEV_CMIS_2/sandbox/spring-cmis/spring-cmis-test/src/main/java/org/springframework/extensions/cmis/test/CmisCreateTest.java

1. testCreateRelationship(): works fine but again returns empty when getRelationships() called with setIncludeRelationships set on Context.

2. testBelarus(): it doesnt work and throws following exception (org.apache.chemistry.opencmis.commons.exceptions.CmisInvalidArgumentException: Bad Request).

I used the code snippet given here in 'Relationships' section
http://chemistry.apache.org/java/developing/guide.html
and was successful in creating it but again finding it difficult to fetch the referred Images for that particular HTML


Please suggest some solution as this is the only thing stopping me from going to Alfresco in prod.

If I am doing it in wrong way (creating relationships) and if there is a better solution for my requirements, please suggest.

Any help is appreciated.

Thanks,
Swanand

The problem with testBelarus is that you are trying to create a relationship of type "cmis:relationship" which is not an association in Alfresco. You need to use an association that is in the content model, like you've done in testCreateRelationship().

I can't tell what's wrong with your getRelationships() call because that code is not included in the snippet.

One thing to watch out for is that the source and target of your association must both be descendants of cmis:document or they won't show up in the getRelationships() call.
