| [virgo-dev] Classloading & Inner frameworks supportability commands |
|
Hi, We are currently working on some supportability features for
OSGi and in particular Equinox. This includes: ·
Classloading - by a given class name list all
bundles that: o
contain it o
export it o
can load it ·
Inner frameworks o
lists all inner frameworks in a tree view o
lists details: § Start
time § Origin
bundle § System
bundle's class § Startup
call stack o
executes certain commands in the inner framework
(list, start/stop, install/uninstall/update) The classloading commands (bundle) can be found here: The inner framework files can be found inside the zip
located here: To install the inner framework bundles & agent: 1. Place the
three main components in one folder (Java agent(FDAgent), Collector
library(FDLib), instrumentation library(javassist)) 2. Add the
package of the framework collector library (com.sap.osgi.frameworkdetection.lib)
to the bootdelegation property (org.osgi.framework.bootdelegation).
Before starting the server add
-javaagent:<path-to-the-agent>FDAgent_1.1.jar to the command line after
the java keyword. 3. Install the
Framework Detection Command bundle in the Equinox environment you just
launched, start that bundle and use the commands it provides. We would like to contribute the code to Virgo since we think
the commands will make the diagnostics of problems (often needed in server
environment) much easier. What do you about this idea? Regards, Hristo Iliev |
