[Android/iOS] Alfresco Mobile : Reverse proxy configuration

jm_pascal — Thu, 06 Dec 2012 09:34:04 GMT

Hello,CMIS in AlfrescoAs you may know, Alfresco Android Mobile uses CMIS protocol to retrieve informations and data from an Alfresco Repository.Since Alfresco 4.x, Alfresco incorporate 2 implementations of CMIS. One historical based on Webscript (/service/cmis) and one based on Apache Chemistry Open

I have only Share server (Alfresco repository is on separate server) exposed externally.
So how does config this apply to that scenario? Is there a way to have Share server act as cmis proxy to repository server? Should the service URL then be /share?

Unfortunately, both the Android & iOS mobile apps communicate with the repository directly i.e. it is not possible to proxy the requests via Share.

It has also transpired that the configuration below will not help with a 4.x server. The /cmisatom binding in 4.x is actually using the server component from OpenCMIS (http://chemistry.apache.org) so the instructions detailed in this mailing list discussion (http://www.mail-archive.com/dev@chemistry.apache.org/msg01759.html) are applicable here too.

I tried with adding new remote endpoints to share-config-custom.xml

        <config evaluator="string-compare" condition="Remote">
                <remote>
                        <endpoint>
                                <id>cmisatom</id>
                                <name>Open CMIS</name>
                                <description>Open CMIS connector</description>
                                <connector-id>http</connector-id>
                                <endpoint-url>http://localhost:8080/alfresco/cmisatom</endpoint-url>
                                <basic-auth>true</basic-auth>
                                <identity>user</identity>
                        </endpoint>
                        <endpoint>
                                <id>service</id>
                                <name>Open CMIS</name>
                                <description>Open CMIS connector</description>
                                <connector-id>http</connector-id>
                                <endpoint-url>http://localhost:8080/alfresco/service</endpoint-url>
                                <basic-auth>true</basic-auth>
                                <identity>user</identity>
                        </endpoint>
                </remote>
        </config>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Then I use for Service URL: /share/proxy
I still get "An error occurred during session creation…", the tomcat access logs shows the initial steps working

What do you think, can this be a possible way (with some additional config) to get share to act as proxy work?

It's highly unlikely this route is going to fully work to be honest. It's not an environment/configuration we have tested and it's not something we're ever likely to support I'm afraid.

If you feel strongly that it should be supported I'd suggest raising this an improvement/enhancement in JIRA so product management can take it into consideration.

Hi JM Pascal,

Your hint did not work for me. Is it verified against 4.2.b/c versions? Ive just replaced the server URL, no servlet or context paths. Reverse proxy works fine using Share.

Thanks in advance.

A solution/workaround is now available for configuring the Android app with an Apache proxy server.

The issue was originally raised as https://issues.alfresco.com/jira/browse/ALF-17109 so I have added details to the JIRA ticket.

I set this up on a 4.1.x server but the same approach should work on 4.2 community servers too.

Please let us know if this configuration does or doesn't work for you.
