@In

org.jboss.seam.RequiredException: @In attribute requires non-null
value: sharedObjectStore.sipSession

I have used the @In attribute for a SipSession...and obviously it s
null....so where do i initialize it first..in the class that handles
my Sip events?

[zubeen]

and as @out?

[Vladimir Ralev]

Most likely you are trying to inject SipSessio from Web context. SipSession is available from SIP and Media context only. If you need to access SipSession from Web context you sould organize them in your own structures (see IPBX where SipSession are stored in a global store)

If this explanation is confusing for you it just means that from a web page action the SipSession doesn't exist. I forgot to tell you that it is a common mistake to call the same component from web and sip/media context. In most cases you can simply do
@In(required=false) and @Out(required=false)

Otherwise what I said is still valid, try to find some way to organize the SipSessions in a shared place.

[zubeen]

i did use required=false...
though im not injecting them anymore...using@Resource for the
SipFactory...which solved the prob BUT
getting a Null Pointer Exception at SipApplicationSession session=
sipFactory.createApplicationSession();

Where is your global store in the ipbx? PbxEventHandler?

[Jean Deruelle]

could you share that stakctrace ? are you sure the sipfactory is injected ? can you post the code using this and the @Resource annotation ?

You sipFactory was not injected, you need to specifically states which application you're accessing

depending on the name of your application

@Resource(mappedName="java:/sip/<appname>/SipFactory") SipFactory sipFactory;

where <appname> is the app name defined in your sip.xml

Alternatively you can use the @In annotation instead.

[zubeen]

thanks...made the change...but same exception

[Vladimir Ralev]

@In SipFactory sipFactory is the right way to do it. It should work from any context
Only @In SipSession sipSession would fail when called from Web context (as SIP Sessions do not exsis in web context anyway).

[zubeen]

ie i wont be able to create a SipApplicationSession from the web
context?

[zubeen]

also, could u please direct me to the file in the IPBX where
SipSession are stored in a global store.

[Vladimir Ralev]

You can still create a SipApplicationSession the web context, you can also create a SipSession from the web context. You can also create many sip app sessions and many sip sessions from a single web context. Thus a 1 to 1 mapping between a web context and a SipSession doesn't exist, that is why it is not possible to inject a SipSession in web context.

You can inject SipFactory as it is only one per application.

[Vladimir Ralev]

It is a bit more complicated in IPBX. The SipSession is stored in http://code.google.com/p/mobicents/source/browse/trunk/applications/ipbx/src/hot/org/mobicents/ipbx/session/call/model/CallParticipant.java
Then the CallParticipant is organized by http://code.google.com/p/mobicents/source/browse/trunk/applications/ipbx/src/hot/org/mobicents/ipbx/session/call/model/CallParticipantManager.java

and other references to the SipSessions and CallParticipants are used in other structures

[zubeen]

also, im getting a null pointer exception at:
SipApplicationSession session= sipFactory.createApplicationSession
();
wether i use @In or @Resource....i think i have got some concept
wrong...as the similar thing was working in a simple sip servlet but
is not working with SEAM TELCO..

[Vladimir Ralev]

I will update the converged demo with something like what you are trying to do. Possibly that would help.

[Vladimir Ralev]

I think I found a probably cause of the wrong behaviour. It seems I deleted the components.properties from src/main the the converged demo app, if you based your app on it, can you check if it's there for you?

[Vladimir Ralev]

Event a missing components.properties should not have that behaviour, so it's still a mystery. One possible reason I can thing of is if you are raising an asynchronous event or have a method annotated with @Asynchrouns. In this case there are special rules on context propagation, only the application context is present inside these methods, if you have any.

Otherwise, I updated the converged demo with click2call function, you can examine the code here http://mobicents.googlecode.com/svn/trunk/frameworks/sip-servlets/seam-telco-framework/examples/converged-demo

[zubeen]

thanks....i found my mistake too ...

[Jean Deruelle]

What was it ? :-)

[zubeen]

mayb it was dirty convoluted code a fn in th sahred store creating
an instance of ChatAction...changed it..called chat action frm the
facelet...prob solved.
now i try to get the request which has beed set as a session attribute
in doInvite...to get the address (which i was previously harcoding to
test)but
GET AN EXCEPTION Caused by: org.jboss.seam.RequiredException: @In
attribute requires non-null value: chatAction.sipSession

public class ChatAction {
@Logger
private static Log log;

//@Resource(mappedName="java:/sip/Seample/SipFactory")
@In(required=false) SipFactory sipFactory;
@In(required=false) SipSession sipSession;

public void sendText(String text)
{
System.out.println("ChatAction : "+text);
StaticSharedStore.chat.offer("me:"+text);

// makeDirty is what actually causes the refresh
StaticSharedStore.makeDirty();

SipServletRequest request= (SipServletRequest)sipSession.getAttribute
("request");<----HERE i try to get the previuosly set attribute...
try {
sendToUser(request.getFrom().toString(),text);

} catch (ServletParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

void sendToUser(String to, String message)
throws ServletParseException, IOException {

System.out.println(to+" : "+message);

SipApplicationSession session= sipFactory.createApplicationSession
();
SipURI from = sipFactory.createSipURI("zubeen","localhost");

SipURI to1 = sipFactory.createSipURI("zubeen","localhost");
to1.setPort(5063);
SipServletRequest request = sipFactory.createRequest(session,
"MESSAGE",from.toString(), to.toString());
request.setContent(message.getBytes(), "text/plain");
request.send();
}


}

[Vladimir Ralev]

You should post the whole call stack to be sure what's going on, but I am 90% certain that you are calling sendText from a Web page (web context) and as I explained before you can not inject SipSession from Web Context. Web contexts have HttpSession, not SIP session. Just like you dont have an HTTP session for SIP messages. Injecting SipSession from HTTP just doesnt make sense.

When you need a particular SipSession from HTTP context you need to first store the SipSession in some known shared location and then recall it in the web context from that location.

Again, IPBX for example. As soon as a SipSession is created it is stroed in the  CallParticipant object, which is then stored in a map (shared location). When I need the SipSession from HTTP context (to send BYE for example) I just lookup the participant by her name and take the SipSession from there.

[zubeen]

but then..you have the name store somewhere...
for me...i need to store the uri somewhere (when getting the invite)
and retain it...while sending the chat message(which is getting called
frm the web context)...im confused :(

[Vladimir Ralev]

Well, when you are in web context and you know that you want to send a chat message to some uri, then you could use the uri as a key for a map that associated uris to SipSessions.

I understand your confusion if you are thinking in terms of HTTP sessions, where this is not allowed. Sip Sessions however can be stored anywhere and used at anytime.

I guess the scenario you want to make is as follows:
1. INVITE comes in and you handle it
2. You take the SIP session for that INVITE and store it in a map like this:
map.put(request.getFrom.getURI(), request.getSession());
3. When you want to send a mesage to some person from the Web UI you just need the SipSession of the person, you look the map and take the SipSession

Also note that in your case you probably want to send SIP MESSAGE requests to the phone. There is a shortcut in this particular case that you could use. SIP MESSAGE is a special request that doesn't need to belong to a particular SipSession (it may or may not). You can just create the request using the sipFactory and send it using a new session (i.e. the mapping is not really requiered).
