Hi:
Recently, I find my OSGI Application cannot find OSGI Configuration
occasionally.
A error of ConfigAdmin indicate the osgi configuration has been
bound to one bundle and cannot be visible to another bundle;
While? Or a bug of felix config admin?
Some details are list as following ps;
1) Ps. The log details
15:10:44,770 | ERROR | guration Updater | configadmin |
5 - org.apache.felix.configadmin - 1.2.4 | Cannot use configuration
wssecurity_resource_out_process for [org.osgi.service.cm.ManagedService,
id=352, bundle=152]: Configuration bound to bundle
mvn:com.tongtech.ti/app-deploy/1.0-SNAPSHOT
Explain of the log:
mvn:com.tongtech.ti/ti-app-deploy/1.0-SNAPSHOT :
the Bundle which deploy properties files as osgi config;
Bundle=152:
the application bundle which using the osgi config;
2)Ps. Some details of my application
My application is composed of two bundle (simplified)
1) AppDeploy bundle: First deploy a Java Properties File as Dynamic
OSGI Configuration and then deploy and start a application bundle. One
Property File will be transformed to One OSGI Configuration(pid=file name).
2) Application Bundle: lookup the OSGI Configuration by the pid at
start up time, and use it.
But occasionally, OSGI Configuration find by application Bundle is
NULL.
Dictionary conf = cm.getConfiguration(pid).getProperties() ; //here
conf is null;
3) The configuration is only visible in App Deploy Bundle;
4) The simplified source code of My application ( details of processing
Factory Osgi is omitted)
1) AppDeploy bundle
String filter = "(felix.fileinstall.filename="+pid+".cfg)";
Configuration[] configs = getConfigAdmin().listConfigurations(filter);
Configuration config = null;
if(configs != null && configs.length>0)
config = configs[0];
if(config == null){
config = getConfigurationAdmin().getConfiguration(pid, null);
}
config.update(properties);
2) application bundle
Configuration config = getConfigurationAdmin().getConfiguration(pid)
//I have ensured,the application bundle started after AppDeploy has update
config of pid;
Config.getProperties(); //return null occasionally;
