---------------------------------------
Assignee: Carsten Ziegeler (was: Felix Meschberger)
> Allow for better configuration of sling home folder
> ---------------------------------------------------
>
> Key: SLING-2203
> URL: https://issues.apache.org/jira/browse/SLING-2203
> Project: Sling
> Issue Type: Improvement
> Components: Launchpad
> Affects Versions: Launchpad Base 2.3.0
> Reporter: Felix Meschberger
> Assignee: Carsten Ziegeler
> Fix For: Launchpad Base 2.4.0
>
>
> Currently a few files and folders in the ${sling.home} folder can be more
> freely located than others:
> * The org.apache.sling.launchpad.base.jar file is expected inside
> ${sling.home}, hardcoded
> * The sling.properties file is expected inside ${sling.home}, hardcoded
> * The start folder containing initial bundles to install is expected inside
> ${sling.home}, hardcoded
> * The Felix framework cache location is configured by the
> org.osgi.framework.storage property
> * The location of Configuration Admin configuration is configured by the
> felix.cm.dir property
> * The location for File Installer (of the OSGi Install facility) is
> configured by the sling.installer.dir property
> To have more flexibility, two new properties should be added:
> * sling.properties (default: ${sling.home}/sling.properties) -- Provides the
> path and name of the sling.properties file contains the configurable
> properties used for starting Sling and then becoming Framework properties
> accessible with the BundleContext.getProperty(String) method. This property
> itself is also available as a Framework property and will be set to the
> default value by the Sling Launcher if not already set. The property must not
> contain a reference to another property but if it is not an absolute path, it
> is resolved against ${sling.home}.
> * sling.launchpad (default: ${sling.home}) Defines the location of Sling
> Launchpad related files and folders. At the moment this is the location of
> the org.apache.sling.launchpad.base.jar library which provides the OSGi
> Framework and the startup folder which takes bundles to install on framework
> startup. The property must not contain a reference to another property but if
> it is not an absolute path, it is resolved against ${sling.home}.
> The defaults are defined such, that they account for backwards compatibility.
> From a little code inspection, probably the following areas have to be
> updated:
> * The Sling class must ensure the property values
> * The Sling class (loadConfigProperties method) must be modified to read
> the sling.properties file from the location indicated by the
> ${sling.properties} property
> * The Launcher class must be modified to look for and place the launcher
> jar in the ${sling.launchpad} folder (instead of ${sling.home})
> * The BootstrapInstaller class must be modified to expect bundles in the
> ${sling.launchpad}/startup folder
