[jira] [Created] (FELIX-4750) getAllServiceReferences() Throw
IllegalStateException: Invalid BundleContext
Chenqiulin created FELIX-4750:
---------------------------------
Summary: getAllServiceReferences() Throw IllegalStateException: Invalid BundleContext
Key: FELIX-4750
URL: https://issues.apache.org/jira/browse/FELIX-4750
Project: Felix
Issue Type: Bug
Components: Framework
Affects Versions: framework-4.0.1
Environment: Centos 6.0 JDK 6
Reporter: Chenqiulin
I register service like this:
public void start(BundleContext context) throws Exception {
Dictionary props = new Hashtable();
// service.pid
String symbolicName = (String) context.getBundle().getHeaders()
.get("Bundle-SymbolicName");
props.put("service.pid", symbolicName);
props.put(Constant.COMMANDNAME, "manager");
serviceRegistrationRuntime = context.registerService(
AgentAction.class.getName(), new ManagerAction(context), props);
logger.info("manager Service regist success.");
}
and I get the service like this:
public Response handle(Message message) {
ServiceReference[] serviceRefs = null;
Response result = null;
try {
String mess = message.getContent().toString();
logger.debug(mess);
Map map = JsonUtil.toBean(mess, Map.class);
logger.info("begin to handle message " + map.get(MODULENAME));
serviceRefs = context.getAllServiceReferences(
AgentAction.class.getName(), "(" + Constant.COMMANDNAME
+ "=" + map.get(MODULENAME) + ")");
// serviceRefs = context.getAllServiceReferences(
// AgentAction.class.getName(),null);
if (serviceRefs.length == 0) {
throw new Exception("has not command service like this");
}
if (serviceRefs.length > 1) {
throw new Exception("more than one command service like this");
}
AgentAction action = (AgentAction) context
.getService(serviceRefs[0]);
// handle the command
result = action.handle(message);
} catch (Exception e) {
result = message.createResponse();
result.setErrorMsg( e.getMessage());
logger.error(e.getMessage(), e);
}
return result;
}
the phenomenon is I always catch the Exception(about 50%) like this:
ERROR - cn.tianya.amm.agent.service.AgentMessageHandler - Invalid BundleContext.
java.lang.IllegalStateException: Invalid BundleContext.
