How to install Web and Mobile as standalone or for your existing Plone site


This document tells how to install Web and Mobile as standalone or to the existing Plone CMS site.

Supported operating systems are all operating systems which run Plone

  • Linux
  • OSX
  • Windows (note: for Windows complete instructions are not available)


The following software stack is needed in order to install and run mFabrik Web and Mobile

  • GCC compiler
  • lxml / libxml2 libraries
  • Python Imaging Library
  • Internet connection is needed during the installation process

Installation of fresh site

These instructions apply if

  • you do not have an existing Plone site
  • you want to test Web and Mobile locally
  • For Plone versions 4.x


Python 2.6 needed, see Python installation instructions below if your Ubuntu distribution does not support Python 2.6 as the default Python interpreter.

sudo apt-get install python2.6 python-imaging wget build-essential python2.6-dev python-setuptools
easy_install ZopeSkel
paster create -t plone3_buildout gomobile # Will create folder called "gomobile"
# Choose Plone version 4.0.1, set your admin password and just hit enter to otherq uestions
cd gomobile
mv gomobile.plone-4.cfg buildout.cfg # Rename to buildout.cfg
bin/instance fg # Start Plone in foreground mode

If your system doesn't have lxml==2.2.6 installed, you can set it up in your virtual environment (no root access required):

If you are using virtualenv, and it has no PIL, just do:



First install XCode and Macports.

The following Terminal spell installs and starts Web and Mobile, after installing Macports

sudo port install python26 py26-pil wget #make sure to install and use python26 from macports
easy_install ZopeSkel
paster create -t plone3_buildout gomobile # This creates gomobile folder
# Choose Plone version 4.0.1, set your admin password and just hit enter to otherq uestions
cd gomobile
mv gomobile.plone-4.cfg buildout.cfg # Rename to buildout.cfg
bin/instance fg # Start Plone in foreground mode


You need MingW compiler enabled.

  • Manually install Plone 4
  • Install lxml for Python used with Plone 4
  • Edit buildout
  • Run buildout
  • etc.

Setting it up

Go to http://localhost:8080.

Follow Create a new Plone site link and create a site with the following add-ons checked.

  • Username/password is admin and defined in your buildout.cfg. buildout.cfg option affects this option only during the installation time and you can change the password in the future through the web interface.
  • Check Go Mobile
  • Check Go Mobile Default Theme

Tick these add-ons

Modifying your local hosts file

Hosts file is your operating system text file which allows you to manually add DNS names on different IP addresses. For testing and developing Go Mobile for Plone you need to assign another name for your local computer, also known as localhost or by IP address

After modifications, the following URL will render in web mode (like before modification)

..but the following will result to the mobile mode

...and the following page is laoded by mobile simulator

hosts file location

On Windows: C:\\Windows\\SYSTEM32\\Drivers\\etc\\hosts

On UNIX: /etc/hosts

Adding required lines

Add the following line to hosts file (note that on UNIX you need to use sudo):       m.localhost preview.localhost

Installation for existing Plone sites

These instructions apply if you want to mobilize an existing Plone site.

Plone 4 buildout.cfg changes

Edit buildout.cfg and add lines:

extends =

eggs =

Plone 3 buildout.cfg changes

Edit buildout.cfg and add lines:

extends =

eggs =

Then follow the instructions above how to modify hosts file and install add-ons in the site setup.

Trunk version for developers

This is needed if you wish to develop Web and Mobile code base.


Subversion 1.6 or later is required, as otherwise Mr. Developer recipes "ignore certificate errors" does not work.

Modify buildout to include Web and Mobile trunk version sources

The following buildout extends are available for you:

  • Plone 3 anonymous
  • Plone 3 commiter
  • Plone 4 anonymous
  • Plone 4 commiter

See gomobile.buildout project for available URLs and files.

Add Web and Mobile snippets to buildout.cfg as described below:


 parts =

 # Need to refer to buidout.cfg extension which lives on Google Code servers.
 extends =

 extensions = mr.developer

 eggs =


For trunk, use eggs = ${gomobile.config:eggs} instead of eggs = mfabrik.webandmobile

If you want to run unit test also include:

recipe = zc.recipe.testrunner
defaults = ['--auto-color', '--auto-progress']
eggs =

You can also make sure that no release versions are included in development buildout:

rm -rf eggs/gomobile.*
rm -rf eggs/mobile.*

Different trunk version buildout options are

You can find available versions here.

gomobile.trunk.cfg is an buildout extension file defining trunk package versions using Mr. Developer buildout extension. You do not want to include this file directly, as depending on the commit access and Plone version you need to get one of the options above.

Files ending with commit-access.cfg and anonymous.cfg are alternative config files extending gomobile.trunk.cfg with the setting of HTTP or priviledged HTTPS checkout protocol.


Dexterity (new Plone system) component version configuration is used as a base to have a good known set of version for Go Mobile for Plone.

Running buildout with Mr. Developer

You can checkout the all code after accepting the certificates using steps above.

Step 1

Activate your Python 2.4 virtual environment (depends on how your Python is installed):


Step 2

Run buildout. This will downlaod remote extensions over HTTP and set-up Mr. Developer scripts:


This will result an error, but makes bin/developer command available.

Step 3

Checks out source code for all packages.

bin/develop co ""

Step 4

Build codebase with checked out source code:


Start Plone


bin/instance fg

...and hope there was no version incompatibilities between products.


To remove Web And Mobile from your site, uninstall all the following add-ons

  • Go Mobile
  • Go Mobile Convergence
  • Go Mobile Default Theme


Uninstallation will lose mobile content settings on all content.

Running automatic test suite

After you have succesfully launched Plone, you can run automatic Go Mobile test suite which includes unit and functional tests. This will guarantee that your operating system libraries and Python module set is compatible with Go Mobile.

To run test suite (using zc.recipe.testrunner):

bin/test -m gomobile* -m mobile*

After test suite completes, it should report zero failures:

Total: 119 tests, 0 failures, 0 errors


lxml too old

If you get start up error:

zope.configuration.xmlconfig.ZopeXMLConfigurationError: File "/home/moo/code/gomobile3/parts/instance/etc/site.zcml", line 15.2-15.23
    ZopeXMLConfigurationError: File "/home/moo/code/gomobile3/eggs/Plone-3.3.5-py2.4.egg/Products/CMFPlone/configure.zcml", line 116.4-116.60
    ZopeXMLConfigurationError: File "/home/moo/code/gomobile3/eggs/gomobiletheme.basic-0.9.3-py2.4.egg/gomobiletheme/basic/configure.zcml", line 16.2-16.39
    ZopeXMLConfigurationError: File "/home/moo/code/gomobile3/eggs/", line 19.4-19.34
    ZopeXMLConfigurationError: File "/home/moo/code/gomobile3/eggs/", line 24.4-29.10
    ImportError: No module named lxml.html

... your lxml library is too old.

Possible workaround

  • Update system-wide libxml2 and libxslt
  • Create python virtualenv with updated lxml

This container already has a Virtual Host Monster

You get this when trying to create fresh Plone 3 site Web and Mobile:

  File "/home/moo/code/gomobile3/parts/zope2/lib/python/zope/interface/", line 535, in subscribers
  File "/home/moo/code/gomobile3/parts/zope2/lib/python/OFS/", line 116, in dispatchObjectMovedEvent

    raise BadRequest, ('This container already has a %s' %
zExceptions.BadRequest: This container already has a Virtual Host Monster

Reason: bug in Plone / Zope. For some reason, it fails to create fresh ZODB database (Data.fs file) properly.


  • Remove mfabrik.webandmobile from buildout
  • rm var/filestorage/Data.fs to clear broken database
  • Run buildout
  • Start Plone bin/instance fg
  • Stop Plone, press CTRL+C
  • Add new Zope admin user bin/instance adduser admin admin
  • Renable mfabrik.webandmobile in buildout
  • Run buildout
  • Start Plone

Unable to preview

If you get this error when opening the preview:

Unable to connect

Firefox can't establish a connection to the server at preview.localhost:8080.

You need to set up /etc/hosts file as explained in the installation instructions.
