Change external alfresco url (/service/cmis) for iphone ap

goebel

Hi

We have a testing alfresco server (4.0c) which is behind a firewall an we want to open it for external use. We did some apache rewrite rules and the web interface for alfresco and share is available from internet. So everything works correctly for alfresco and share.

The server is available through internal url : http://myalfresco:8080/alfresco
The server is available through external url : http://www.mycompany.com/alfresco

But when we try the iphone/ipad application, we are able to connect and see the sites. But when we try to enter a site we get an error in the ios app "Alfresco Mobile did not connect to http://myalfresco:8080/alfresco/service/cmis/s/workspace/…..
The problem is that the iphone app gets the internal url from the webservice. When I try the url from internal network I am able o download the xml data which is send from the server to the client. In this xml data, all the href point to http://myalfresco:8080/alfresco instead of http://www.mycompany.com/alfresco

I checked the forums and tried a lot of modifications in alfresco-global.properties but whithout success 😞
For instance, I tried to change these parameters

repo.remote.url=http://www.mycompany.com/alfresco
url.serviceContext=http://www.mycompany.com/alfresco
url.serverPath=http://www.mycompany.com/alfresco

Every time I tried the cmis services, I always get the internal hostname

Does anybody have a hint how to fix it ?

Thanks a lot

The last comment in that JIRA issue is definitely the correct way to solve the problem. I say "definitely" because we had to solve the exact same issue for our soon-to-be-released cloud service.

Thanks,

Thanks for your reply

Which version you tried 3.4 or 4.0 ? I use 4.0.c and there is no folder <tomcat>/shared/classes/META-INF
So I created the folder and file but it still does not work as expected

Georges

That should work on both 3.4 and 4.0. Check your Tomcat configuration is set to look in the shared/classes area. Look at steps 3 and 4 here: http://wiki.alfresco.com/wiki/Install_Tomcat6

Thanks,

Hi

I use the alfresco 4.0c distribution where tomcat is bundled. Nevertheless, I tried your advise but still without any change

In alfresco 4, there is a folder "alfresco-4.0.c/tomcat/shared/classes/alfresco/extension" with a sample file "web-scripts-config-custom.xml.sample". I also changed this file with the modifications of the JIRA MOBILE-42. Still no change 😞

In the file ./tomcat/webapps/alfresco/WEB-INF/classes/alfresco/web-client-config.xml there is a section

<config evaluator="string-compare" condition="Server">
      <!– The public web server hosting this web client –>
      <server>
         <!– Enable and adjust the following settings to allow for proxied use of Alfresco 
         <scheme>http</scheme>
         <hostname>localhost</hostname>
         <port>8080</port>
         –>
      </server>
   </config>
‍‍‍‍‍‍‍‍‍‍‍‍

But changing the values to the external adress does not affect the behaviour of the iphone app. Ther is still the local url in the xml. (I try from an external client the adresse http://www/mycompany.com/alfresco/service/cmis)
The resulting xml contains the internal hostname. Is there somewhere else a property to change

Here you find a sniped of the xml

Please try again with the correct path and filename that are specified in the JIRA ticket.

Thanks,

Hi,

I did exactly what was written in the JIRA issue

1) I created the missing directory META-INF : alfresco-4.0.c/tomcat/shared/classes/META-INF
2) I created the file spring-webscripts-config-custom.xml in the folder alfresco-4.0.c/tomcat/shared/classes/META-INF
3) restarted alfresco
4) tried with iphone

Still the same issue

Next I added the folder alfresco-4.0.c/tomcat/shared/classes/META-INF to the catalina.properties in tomcat/conf and restarted. Same issue

Do I miss something ?

Georges

goebel

It is working !!!!

You have to add "shared.loader=${catalina.base}/shared/classes" to the tomcat/conf/catalina.properties (without META-INF) and the restart.

You have to create the folder and file as described in the JIRA

Thanks man, you saved my day. Now I will grab some beer to celebrate 🙂

Unfortunately I seem to have also bumped into the same problem.

I'm using nginx to provide reverse proxy, and access on both http and https works for web and android (using JM Pascal's ALF-ACC Mobile lite, and Zia's Freshdocs for testing). But on ipad (and other iphones), with Alfresco Mobile, and Zia's Freshdocs, this only works on the http interface, and fails on the https interface with the error messages:

"Alfresco Mobile did not connect to https://externalhostname:443/alfresco/service/cmis…

The URL is correct, since when I just swipe off https, I can connect again via http.

My steps are:

1. mkdir /opt/alfresco/tomcat/shared/classes/META-INF

2. vi /opt/alfresco/tomcat/shared/classes/META-INF/spring-webscripts-config-custom.xml

<alfresco-config>
      <config evaluator="string-compare" condition="Server">
      <server>
         <scheme>https</scheme>
         <hostname>externalhostname.com</hostname>
         <port>443</port>
         <path>alfresco</path>
      </server>
   </config>
</alfresco-config> ‍‍‍‍‍‍‍‍‍‍

3. check that /opt/alfresco/tomcat/conf/catalina.properties has:

"shared.loader=${catalina.base}/shared/classes"‍

In fact, my installation already has

shared.loader=${catalina.base}/shared/classes,${catalina.base}/shared/lib/*.jar‍

4. restart alfresco

On the ipad, I can use Safari to connect to the URL https://externalhostname:443/alfresco/service/cmis, and after a login, get the cmis output, which shows my URLs are of the correct form,e.g.

…
<collection href="https://externalhostname.com:443/alfresco/service/cmis/s/workspace:SpacesStore/i/05754434-33cb-410b-885e-4506d6fa621c/children">
…‍‍‍

Prior to doing the 4 steps above, the URLs were just "http://127.0.0.1:8080" so obviously this change is working.

Any thoughts as to why this isn't working? Bearing in mind that on the Android platform, all the apps I've tried so far appear to be working, so is this an issue specific to the iOS (Apple, no Cisco) platform?

xarope

anybody else encountered this same problem with access via apple products and SSL proxy? As I mentioned, it seems to work on the android devices and apps I've tried (as well as normal web access), just not on any ipad/iphone apps.

xarope

anybody? I'm desperate enough to do some packet capture and try to figure out what is going on (I can feel my eyes watering already!)

Hey everyone,
I am also facing the same issue while accessing the URL from an iPad app but in a Multi-tenant environment with SSL enabled.
I was able to solve this issue when MT was not enabled.
But the same issue started occuring after enabling Multi-tenancy.
THis totally works fine in Android devices but not in iPad. The META-INF folder creation has no effect in MT and SSL enabled server. Could somebody pls help on this ????

Thanks !!!!!

umamaheswari

Hey hi !!!

I am facing the same issue.. Were you able to resolve that in any means?? can u pls help with this ??

Hi all,

in my environment, the changes have effects only with the old (alfresco 3.x) CMIS AtomPub binding "alfresco/service/cmis":

https://your.dns.com/alfresco/service/cmis

If I configure my Android device with the new CMIS endpoind Urls, it doesn't work.
You can check the correct server hostname by opening the available CMIS Urls in your browser:

For Alfresco 3.x : https://your.dns.com/alfresco/service/cmis
For Alfresco 4.0.x and Alfresco 4.1.x : https://your.dns.com/alfresco/cmisatom
For Alfresco 4.2 and Alfresco 5.0: https://your.dns.com/alfresco/api/-default-/public/cmis/versions/1.0/atom

My App Stack
- HTTPS access through Apache Server 2.0 with http proxy/reverse
- Alfresco Community 4.2.e
- Android 5.1.1
