Some standard OSGi framework configuration properties
Property name
Spec
Meaning
R4.2
A file system path to a directory,
which will be created if it doesn't
exist. If this property isn't set, a
reasonable default is used.
org.osgi.framework.storage
R4.2
Specifies if and when the storage
area for the framework should be
cleaned. If no value is specified,
the framework storage area isn't
cleaned. Currently, the only pos-
sible value is
onFirstInit
,
which causes the framework
instance to clean the storage
area the first time it's used.
org.osgi.framework.storage.clean
org.osgi.framework.system.packages
R4
Using standard
Export-
Package
syntax, specifies a list
of class path packages to be
exported from the system bun-
dle. If not set, the framework
must provide a reasonable
default for the current VM.
org.osgi.framework.system.packages.extra
R4.2
Specifies a list of class path
packages to be exported from
the system bundle in addition to
those from the previous system-
packages property.
org.osgi.framework.startlevel.beginning
R4.2
Specifies the beginning start
level of the framework.
org.osgi.framework.bootdelegation
R4
Specifies a comma-delimited list
of packages with potential wild-
cards to make available to bun-
dles from the class path without
Import-Package
declara-
tions (for example,
com.sun.*
).
By default, all
java.*
packages
are boot delegated. We recom-
mend avoiding this property.
org.osgi.framework.bundle.parent
R4.2
Specifies which class loader is
used for boot delegation. Possible
values are
boot
for the boot
class loader,
app
for the applica-
tion class loader,
ext
for the
extension class loader, and
framework
for the framework's
class loader. The default is
boot
.
