CMIS Configuration and WebSphere ECM Adapter

Hello,

I am working on integrating OpenText Content Server into an enterprise solution with WebSphere Process Server as the middleware. Recently, IBM introduced an ECM Adapter to simplify integration with CMIS-enabled content repositories. We are not in control of the OpenText environment, but have been working with the support team to have ELS configured correctly. Thus far, we haven't had luck.

To give an overall picture of the solution, OpenText Content Server 10.0 is installed with ELS 10.2.0. The CMIS Connector is apparently installed (I am able to view all the service descriptions and WSDL's through a browser), and an ELS Application has been set up for us. However, we haven't quite figured out how all these pieces tie together, and I have not found a comprehensive set of documentation that describes our scenario. (The ELS Scenario Configuration guide provides very little information about CMIS and the CMIS Technical Documentation does not provide sufficient information about the configuration).

Are there any comprehensive examples available that will help us with the end-to-end configuration of our scenario? I believe there must be something missing on the OpenText side.

From a WebSphere ECM Adapter side, it requires only the following information:

CMIS Server URL - not sure exactly which URL is required here, but I'm guessing it's the same as my Repository Service URL minus the "RepositoryService" part of it.
Username / Password- do I use the ELS Application credentials? Or should I be using CS user credentials?
CMIS Repository Service - we have this information.

Any help would be greatly appreciated!

Hello Faraz,

the CMIS Services are laid on top of the Enterprise Library Services Application (which is the Java Service Layer for the Content Server) and map all CMIS service functionalities to the ELS ones.

If you installed and configured ELS correctly you don’t need further configuration for CMIS after installation.

If you get the WSDL from the browser, then the CMIS connector is working properly.

To bind the CMIS Web Services please use the URL http://<els_server>:<els_port>/ot-cmis/services/RepositoryService?wsdl

ELS 10.2.0 doesn’t support Atompub binding. This was implemented in the ELS 10.2.1.

As for the CMIS specification (http://docs.oasis-open.org/cmis/CMIS/v1.0/os/cmis-spec-v1.0.html ) you’d need to call the RepositoryService.getRepositories() to get the list of the available repository Ids. The Content Server Workspace would be typically exposed with Id=2000 on standard installations. Then you could request a RepositoryService.getRepositoryInfo(“2000”) (just an example) to retrieve further repository information.

Working with OT CMIS requires ELS Credentials (OTDS or CAP according to the installation) either through a “Basic Authentication” or through an “OT ELS Authentication”. About the latter please refer to the ELS Programming Sample here.

The authentication seems indeed to be your problem by now (“No ticket is returned”).

Regards,

Stefano

Hi Stefano,

Thanks for the information. I agree that the authentication appears to be the missing piece. For credentials, we have tried the following:

Content Server Credentials (e.g. the username/password I can use to access Content Server from the browser)
The ELS Application Credentials (e.g. the Application Name and Password)

Are the ELS Credentials required different from what I've listed here?

I'll take a look at the sample applications you suggested.

Thanks,

Faraz

Hi Faraz,

ELS Credentials are the same as for the Content Server, no matter if your installation uses OTDS or the legacy authentication (CAP). In general you don’t need to authenticate the ELS application especially if you then try to connect the Enterprise Workspace repository (id=2000).

For a first try I would use administrator’s credential, if any available, to override any further restrictions you might encounter.

Hi Faraz,

in the case you use OTDS, you must make sure that the user is member of an OTDS Access Role which belongs to the RCS-Resource.

Faraz,

Did your team ever manage to connect WebSphere to the CMIS Connector? I'm looking to do the same with IBM WebSphere Portal 8 and Connections 4.0 but I don't have ELS in my environment, only the CS 10 server. I wanted to know if it was even possible before I standup Archive Server and ELS in a sandbox.

Thanks

Joaquin

Hi Joaquin,

I can't give you an answer concerning connecting IBM Webshpere to CMIS, but want to tell you that for CMIS you could use a system without Archive Server.
For a proof of concept, this is absolutely fine. It might make things a bit easier.
Note however, that ELS is required.

Regards
Uwe

No, we were not able to make this work with the ECM Adapter. We are using the CMIS Web Services directly instead.
