1.1	1	= Use MongoDB =
2.1	2
1.1	3	If your application uses an important set of values, you can choose to store them in MongoDB :
2.1	4
4.1	5	* create a database: use databaseName;
	6	* create a user on it: db.createUser({user : "username" ,pwd : "password",roles :["readWrite"]}) ;
	7
	8	In the System Parameters, modify MongoHost, MongoPort, MongoDatabase, MongoUser and MongoPassword
	9	[[image:Capturedecran2015-06-04a15.45.54.png]]
	10
6.1	11	You have now to create a java class in order to make your bundle to listen to the service TimeSerieMongoClientService. In the pom file’s directory of your bundle execute following command:
	12
	13	* mvm clean install
	14	* mvn eclipse:eclipse
	15
	16	Then import the bundle as an eclipse project to add that class which activate the service :
	17	Right click -> Import -> General -> existing project into workspace and specify the folder of your bundle in tomcat/dysoweb.home/application
	18	[[image:Capturedecran2015-06-04a16.13.56.png]]
	19
	20	Create a class Activator in the folder src/main/java:
	21
	22	{{code language="java"}}
	23	public class Activator implements BundleActivator {
	24
	25	private BundleContext fContext;
	26	private IApplicationService fApplicationService;
	27	private static Activator fInstance;
	28	private ITimeSeriesMongoClientService fMongoService;
	29
	30	public Activator() {
	31
	32	}
	33
	34	public void start(BundleContext context) throws Exception {
	35	fContext = context;
	36	registerApplicationServiceListener(context);
	37	registerMongoServiceListener(context);
	38	fInstance = this;
	39	}
	40
	41	public void stop(BundleContext context) throws Exception {
	42	fContext = null;
	43	fInstance = null;
	44	}
	45
	46	public static Activator getDefault() {
	47	return fInstance;
	48	}
	49
	50	public IApplicationService getApplicationService() {
	51	// retrieve the import service for the running instance
	52	return fApplicationService;
	53	}
	54
	55	private void registerApplicationServiceListener(BundleContext context) throws InvalidSyntaxException {
	56	// get the service ref if the auth plugin is already started
	57	ServiceReference sr = context.getServiceReference(IApplicationService.class.getName());
	58	if(sr != null) {
	59	fApplicationService = (IApplicationService)context.getService(sr);
	60	}
	61
	62	ServiceListener sl = new ServiceListener() {
	63
	64	@Override
	65	public void serviceChanged(ServiceEvent ev) {
	66	ServiceReference sr = ev.getServiceReference();
	67	switch (ev.getType()) {
	68	case ServiceEvent.REGISTERED: {
	69	fApplicationService = (IApplicationService)fContext.getService(sr);
	70	}
	71	break;
	72	case ServiceEvent.UNREGISTERING: {
	73	fApplicationService = null;
	74	}
	75	break;
	76	}
	77	}
	78	};
	79
	80	String filter = "(objectclass="
	81	+ IApplicationService.class.getName() + ")";
	82	context.addServiceListener(sl, filter);
	83	}
	84
	85	private void registerMongoServiceListener(BundleContext context) throws InvalidSyntaxException {
	86	// get the service ref if the auth plugin is already started
	87	ServiceReference sr = context.getServiceReference(ITimeSeriesMongoClientService.class.getName());
	88	if(sr != null) {
	89	fMongoService = (ITimeSeriesMongoClientService)context.getService(sr);
	90	}
	91
	92	ServiceListener sl = new ServiceListener() {
	93
	94	@Override
	95	public void serviceChanged(ServiceEvent ev) {
	96	ServiceReference sr = ev.getServiceReference();
	97	switch (ev.getType()) {
	98	case ServiceEvent.REGISTERED: {
	99	fMongoService = (ITimeSeriesMongoClientService)fContext.getService(sr);
	100	}
	101	break;
	102	case ServiceEvent.UNREGISTERING: {
	103	fMongoService = null;
	104	}
	105	break;
	106	}
	107	}
	108	};
	109
	110	String filter = "(objectclass="
	111	+ ITimeSeriesMongoClientService.class.getName() + ")";
	112	context.addServiceListener(sl, filter);
	113	}
	114
	115	public ITimeSeriesMongoClientService getMongoService() {
	116	return this.fMongoService;
	117	}
	118	}
	119
	120	{{/code}}
	121
	122	To solve import errors, edit the pom.xml file:
	123
	124	* add a dependency:
	125
	126	{{code language="xml"}}
	127	<dependency>
	128	<groupId>com.requea.dynapage</groupId>
	129	<artifactId>com.requea.dynapage.mongo</artifactId>
	130	<scope>provided</scope>
	131	<version>4.0.245</version>
	132	</dependency>
	133
	134	{{/code}}
	135
	136	* add an import package:
	137
	138	com.requea.dynapage.mongo,
	139
	140	* add a field bundle-activator after Import-Package mark:
	141
	142	{{code language="xml"}}
	143	<Bundle-Activator>com.requea.schneider.dlvm.Activator</Bundle-Activator>
	144	{{/code}}
	145
	146
	147	Under src/main/META-INF, edit MANIFEST.MF:
	148
	149	* add com.requea.dynapage.mongo in the section Import-Package
	150	* add the section Bundle-Activator: com.requea.name.Activator
	151
	152	Recompile the bundle with the command line mvm eclipse:eclipse
	153
	154	You can now add your bundle by typing that command in the shell platform (under http://localhost:8080/dysoweb/dysoweb/panel/secure/shell.jsp):
	155
	156	start reference:file: /path to the bundle //com.requea.name///src/main
7.1	157
	158	If you change the version of Mongo and get an authentication error, you have to delete and recreate the folder /data/db
