The following preconditions must be met before you can install the Widget Framework Core:
A suitable version of the Escenic Content Engine and Escenic assembly tool have been installed as described in the Escenic Content Engine Installation Guide and are in working order.
You have the credentials needed to access Escenic's SW repositories.
The following plug-ins have been installed as described in the relevant plug-in guides, and are in working order:
Menu Editor (3.1 or later)
Analysis Engine (3.0 or later)
Until recently, all
components had to be installed by manually downloading and unpacking
archive files. This is no longer the case. The
itself, the assembly tool, the ece scripts and all plug-ins are now
deb packages (for installing on
Ubuntu/Debian systems) and as
rpm packages (for
installation on RedHat/CentOS systems). This is now the recommended method
systems, although it is still possible to use the old method based on
manually downloading and unpacking archives. Note, however, that when you
are installing a plug-in on an existing
installation, you should use the same installation method as you used for
Using the new package installation method offers many advantages over the old manual installation procedure:
It is faster and quicker
It is significantly less error-prone
It supports a fully automated upgrade process in which not only the installed packages themselves are upgraded, but also deployed EAR files. An upgrade script automatically checks the EAR files for copies of JAR files that have been updated, and replaces them with the new versions.
The old installation method will continue to be documented for the moment.
Components installed using the new method are installed in
/usr/share/escenic, whereas the old method recommends
/opt/escenic, and some other path
components are slightly different. To cope with these differences, the
following placeholders are used in some paths:
|Placeholder||NEW METHOD path||OLD METHOD path|
When installing the Widget Framework, you should use the same method as you used to install the Escenic Content Engine.
Note that if you are planning to install the
Escenic Content Engine
using the new package-based method, you can install the
simultaneously by simply including the
package name (
widget-framework) in the
apt-get installation command. You only need to follow
this procedure if you have already installed the
and now need to install the
If you use CUE as your Escenic editor, then in addition to installing the Widget Framework, you should also install a matching CUE Widget Framework plug-in into CUE. This plug-in adds template editing capabilities to CUE. Whichever method you plan to use for installing the Widget Framework itself, CUE plugins are always package-based installations. For details, see CUE Plug-in Installation.
