Client Call back and socket permissions
Hi,
Im thinking of a client call back from the server. I dont know much about the RMI under a firewall.
Do I need to make an entry in the firewall proxy server so that the RMI Server make a call back to the client?
Or the client can directly call a server behind a fire wall and a server can make a client which is behind a fire wall too.
Any suggestions, please let me know.
Thanks,
ananth
Servers cannot "call back" to clients behind firewalls. Period.
Clients can call servers behind firewalls, but you will probably have to provide a custom socket factory so that a fixed port - rather than a random port - is used for remote method calls.

I'm doing some research and it wasn't clear to me in the
documentation I came across how Developer (Forms) Server
supports client-side callbacks when a client-side firewall is in
place. Can anyone offer some insight here?
Thanks!

Hi, every one:
Here's my question of my day - >>>
I am using weblogic 6.1 SP2 right now - running on Unix and Win 2K, and
I got a web service up and running called Price Update web service through
which user can pick up a price and push a deal to another web service
called: deal service, the deal service will take the user deal and book the
deal ( sending a JMS message to a Queue, a MD will pick up and do the work,
then send the confirmation to another JMS Queue ), then the confirmation
will be picked up and sent to another web service , called: User Deal
Confirmation Service, here's the question:
1. Since the client application is only allowed to see its own confirmed
deals, how I can make the confirmed deal encrypted based on a server
generated key or the session id that client application provides
2. Now, I have 3 webservices: update, deal and confirm, each of them has a
client.jar file available - from the client application point of view, do I
need all these 3 client.jar, or I just need one of them ?????
3. How can I use web service call back in wls 6.1 sp2 ?????? - in the 7.0
beta, you can do this easily in the workshop, in the second question above,
I think I need some how relate the confirmation to the client conversation
id ??
thanks a lot for the input, have a nice day.
regards,
mark.Any comments ?

Issue with Task Control Call back and Event Choice in WLI BPM 8.1
Hi,
I am using a Task Control Factory to create Task Control Instances in a loop
and then
create tasks and assign them to a predefined group. I have an event choice
for two events
waiting for the onTaskCompleted and onTaskAborted event call backs.
I have two such operations (of task creation) in the same loop. For
simplicity I have used two separate task factory controls for each of the
tasks (because I even had worse problems using a single control factory for
both tasks in the same loop).
When I instantiate the process, through work list I am able to claim, start
and complete the first task. When I try the same procedure (claim, start and
complete) on the second task, the the event choice for the corresponding
task receives 2 event call backs. First it receives the onTaskCompleted as
expected, but then it also received another call back of the same type which
displays the error on the server log as:
<Sep 24, 2003 9:43:56 AM EDT> <Warning> <WLW> <000000> <on process

Does anybody know why two events are fired for the same work list action?
Thanks in advance.

ITunes Match Skipping for months. 2 seperate apple staff promise to call back and never do!
Dear all,
I loved iTunes match for almost a couple of years. However for the last 3 months or so what ever songs I add to my iTunes library on my iMac and then send to iTunes match will not play on either my iPhone, or iPad. I am extremely annoyed about the whole thing as I have phoned Apple technical support on 2 separate occasions and gone through all the usual try this and try that. I have even restored my iPhone and iPad but still it does not work. Strangely all songs work fine on my Apple TV's and my iTunes library on my iMac.
What annoys more than it not working is the fact that I have had 2 members of staff promise to look into it and call me back, they never do! I have had a direct email for the 2nd member of staff and even had a few replies from him arranging a suitable time to call but he didn't. I then tried to email him the other day to find that the email got an automated reply saying no such address. I can only assume the member of staff in question has left?
PLEASE PLEASE PLEASE someone help. Apple staff - do you read these posts? If so SOMEONE CALL ME BACK!
For the record all devices are up to date. I even upgraded to ios8 and have even bought an iPhone 6 but the problem still occurs.
I love Apple and their products but this is a complete shambles. 3 months of a service I cannot use and my subscription is about to renew. I am a music teacher so this feature used to be great. I think I will not be using this anymore unless it gets fixed asap?
Can Apple wipe the iTunes Match data for my account so I start again and upload my library as if all brand new?
Moan over I await a response but I won't hold my breath.I have probably spent 15 hours over 3 months trying to solve this problem.......to no avail.

Stateless Bean - scope of instance variable in EJB Timer call back function
Hi,
I would like to know on the scope of an instance variable of a Stateless Bean object,
when used in a EJB Timer call back.Let me explain this in more detail below.
I have a requirement to use a EJB Timer.
For this, I have created a stateless object since Timer creation needs to be done
from a stateless bean. I have a member variable "count" of the stateless bean class.
In the timer call back(ejbTimeout), I am able to use this count variable during
each time of the call back, and the value of this variable is also updated properly.
I have a few queries with respect to the above behaviour:
1) Does stateless bean object not get destroyed once the Timer is created from the Bean?
2) If the Bean object is not destroyed, then when does the bean object get destroyed?
3) If both (1) and (2) are not true, then can anyone explain on how the above behaviour is possible?
Thanks in advance,
UlrichHi Ulrich,
The ejb timer is associated with the stateless session bean component, not with a particular bean instance. There is no formal relationship between the bean instance that called createTimer() and the bean instance on which the timer callback happens. If they're the same in your test run that's just a coincidence and not something your application should be depending on.
In the stateless session bean model, the container can create and destroy stateless session bean instances at any time. The container is free to pick any stateless session bean instance to service any client invocation or timer callback. If you need to pass context into a timer callback, one way to do it is via the timer "info" object. However, the info object is immutable so it wouldn't be a good match for a counter. You could of course always just use a database for any necessary coordinated state.

I'm quite new to using unity and IVR so sorry if this is a stupid question. I have a group of users who have asked If a client called and no free agent is avaliable or busy that the IVR will prompt the agent if they would like a call back. Then callcenter should automatically do call back for these clients (who select call back) but when agents become free. Is it possible and how?
ThanksWhere does Unity fit into IVR, scripted call backs, and etc? Is this a CUE deployment? What type of setup do you have going?

Calling back with empty distribution points list
Hello
We are running sccm 2012 R2 cu0 and encounter a strange behavior regarding users not able to use the software catalog.
Some background :
We setup primary site and 3 DPs while running sccm 2012 sp1, then upgrade ro R2, then cu0
then we setup 10 DPs and start deploying clients.
All Clients looks well configured using the "Configuration Manager". All packages are replicated onto those DPs (except ms updates so far)
Clients that are assigned to boundaries linked to the 3 DP made while running sccm 2012 sp1 are running smoothly. They can use the apllication catalog
The one that are assigned to site where dp have been build with R2 cu0 can't use catalog.
They all got this message in the :
LocationService.log on the clients
Calling back with empty distribution points list LocationServices 11/12/2013 12:27:05 78432 (0x13260)

Ad schema is ok, boundaries and boundary groups also.
I compare new DP vs "old" ones and there is no difference in the configuration.
I looked at some logs but didn't found any relevant information.
I also read all similar post but none looks "similar" to our configuration
If someone can "guide" me to troubleshoot this, it will be appreciate.
Feel free to ask for any information
ThanksHi,
Could you please use IP ranges instead of your boundary to test whether
the clients could get DPs?
If this could work, there should be a problem with the boundary of AD sites.

I have already contacted apple thru email, twice. I don't see that they have an option for a call back for a missing iTunes balance, I did however see where I could get a call back(and did) for not being able to sign in on another device to make a purchase. This problem was resolved quickly for this device. I told this rep about the unresolved problem of the missing iTunes balance and he said he could transfer me but the wait times are very long. In my 2 email correspondences on this missing balance issue both times I was told to check my balance history- which does not resolve the issue that I am having to go thru a huge hassle to get my missing balance back prior to my card purchase. I had a balance of $5.86 show on my ipad2 and on my Mac book pro prior to applying the $25 gift card. Then the balance showed only $25 after apply my gift card, now here's what's weird: aprox. A week and a half later I sign in on my iPod touch and shows a balance of $5.30!, but when it has me resign into iTunes that balance disappeared, and the $25 gift card balance shows up. I made NO PURCHASES to use the $5.86/ or $5.30- so I want my money to equal $30.30/ or $30.86 as it should, and I want to not go thru so much to take care of it. To just hope Apple would have a call back option for this type of issue. I won't be buying iTunes gift cards or purchasing thru iTunes if my balance disappears when I do so.
When you tried to contact Support with the card's images how were you trying to do it, on your phone or a browser on your computer ? And have you tried a different browser to see if you get the same error message ?
As well as images of the card they might also want an image of its receipt.
And to contact Support you were using : http://www.apple.com/support/itunes/contact/ , and clicked on Contact iTunes Store Support on the right-hand side of the page, then iTunes Cards And Codes ? -
For all those who say Verizon never calls back.
I tried to activate a STB last night that was picked up at a store just before closing. The box would not activate, even after the Cable CARD did an automatic firmware update. I contacted Customer Support and the box still would not activate because of some type of pending order on my account. Normal tech support agents cannot access accounts, for the customers protection, and theirs.
I was told that I would receive a return call within one to two hours. WOW! Within 15 minutes a supervisor called back and said the issue was resolved with the pending order for some type of future activation. Glitch? But the Supervisor had the box up and running within 30 minutes, and staid on the phone with me until I could go upstairs and Verify the proper operation.
Kudos to Verizon and their Fiber Solutions Center CSRs!that would explain why I never get a call back - my guy was busy calling you

Someone called me and didn't get my voicemail
I know that my voicemail is set up, has been for years. And if it isn't the caller gets a message that either it's not set up or the account is full. But I had someone tell me that they called me and there was nothing. Is this something that could have been cause by me picking up the phone call at just the right point and a switching error happening? Because I remember picking up a phone call and no one being on the other side.
The person that called probably hung up just as you answered. The phone wasn't ringing long enough to go to voice mail and that number gets registered on your missed call log. Since you said that your voice mail has been set up for a long time. it's probably working fine. Have that person call back and leave a voice mail and see what happens. If it works, nothing to worry about.

RMI call back - How to refer to the client project from the server project?
Hi, I am working on an RMI assignment which basically needs me to use the RMI call back for the server to notify the clients.
I have 2 projects , one for the client and another for the server.
In the client project, I have a client interface and the main client class implements this interface.
In the server project, I have a server interface and a class that implements this interface.
I can use the server interface in the client project's code by adding the server project in the path of the client project. it lets me use the server interface in the code if I put "import.." statement.
But the issue is I can not do the same to access the client interface from within the server project's code. Since that will be a circular reference, the compiler does not let me use the client interface from within the server's code. This is putting me in a great difficulty and I am stuck here. What should I do so that I can use the client interface and the compiler won't complain?
Thanks for any help..
Regards.. jsLet me explain what I tried: I manually generated stub class of the client using the Eclipse IDE as mentioned in my previous message. The StockMSClient_Stub.class got created in my client project.
The common project has the 2 interfaces - one from the client and one from the server.
I have added reference to the common project from the client and server projects to use the interfaces.
With the above mentioned in place, when I run the server project, the registry binding of the server objects is very fine. But I am getting error in the applet at the line where I am passing the client object to the method provided by the server interface. The following is the code snippet in the applet where I am getting the error.
specifically the line: String response = objs.login(userId, password, smsClient); ====================
public void login() {
Registry reg = null;
String userId = "test";
String password = "test";
this.smsClient = new StockMSClient();
try {
reg = LocateRegistry.getRegistry(rmiHost,rmiPort);
UserInterface obj = (UserInterface) reg.lookup(rmiStrings
[1]);
User u = obj.find(userId);
if (u == null) {
System.out.println("This user is not valid");
} else {
UnicastRemoteObject.exportObject(smsClient);
reg = LocateRegistry.getRegistry(rmiHost, rmiPort);
LoginLogoutInterface objs = (LoginLogoutInterface) reg
.lookup(rmiStrings[0]);
//getting error at the following line.
String response = objs.login(userId, password, smsClient);
System.out.println("response :" + response);
} catch (AccessException ae) {
System.out.println(ae);
} catch (NotBoundException nbe) {
System.out.println(nbe);
} catch (RemoteException re) {
System.out.println(re);
} //end login()====================
Error is:
java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is:
java.lang.ClassNotFoundException: sms.rmi.graphics.StockMSClient_Stub (no security manager: RMI class loader disabled)================
I don't know why this is happening..Please help.

Re: Forte and OrbixWeb call-back
We have created a business process manager (BPM) layer between our client GUI
and business model objects that supports Java call-in/call-out. This enables
switching out the Forte windows with Java windows for a web solution with
minimal code re-write.
We were able to get most functionality to work as per our design, which
included registering a call back function from a Java GUI in the BPM, but had
to make some sacrifices due to a Forte bug, at least under 3.0.D. We turned
in case #38434, detailing errors when we tried to fire a callback method with
parameters, example below ("callback" was the Java object passed in.)
method TestIIOPBackend.FireCallback(input message: Framework.string)
begin
if callback != nil then
task.part.logmgr.putline('Firing callback');
//WORKS
callback.CallMe();
//ERROR!
callback.CallMeString(message);
else
task.part.logmgr.putline('Callback not set');
end if;
end method;
This may have been fixed in 3.0.F, we found a way to work around it in our
design and haven't investigated since.

1) Do you have experience with PowerBuilder and Forte' applications running at
the same time on the same (laptop) computer? Here I'm thinking
about any potential resource constraints? Memory Requirements?As log as you are using Win95 or NT you should not be concerned about WIN-resources. Memory depends more on what your 2 tier PB application requires than what your Forté would require.
