Why don't you give us the money your Boss pays you.. then we'll see what can be done ;)
Seriously, it might be smart to start your own research first. Check out what VoiP and SIP are all about, and the check how it fits into J2me.

1. how can i get sound from mic to use in app and in which format
2. is it ok to buffer sound n then transfer it over network?
3. voice buffer direclty goes to other client mobile or processed at sipserver before reaching the client mobile.
4. audio streaming is possible or not for S60 3rd edition.

How to implement Lag over in OWB?

Hi,
Could any one please explain, how we can implement lag over in OWB?
Thanks and regards
Gowtham Sen.

Hi Borkur,
Thanks for reply.
Actually I want to implement it in OWB. But after I got the answer from you, I decided to do in some othere way.
The way you mentioned is right when we are performing the operations directly on a table.
But in my scenario, an intermediate data is generating. I want to perform lag over operation on those records. Its possible by view.
So for performing operations for intermediate result, Oracle is providing Table Function concept. I can pass the result to it.
But the problem again is, how to implement the lag over operation there.
Any idea.?
Thanks and regards
Gowtham sen.

How to implement SQL Over-ride on Source Tables in OWB?

How can we acheive SQL-Override feature similar to the one available in informatica on OWB.
We are thinking of using a view to filter the required data.And defiinig the view as the source in the mapping.
Is this the best approach to go by,any thoughts suggestions?

Informatica is a pipelined client/server ETL tool which means that if you read from a table and then apply a filter it will read all of the data onto the client (i.e. the application server, not a user machine) and then filter the data so it is not unusual for developers to want to put a lot of the logic into the SQL to reduce the number of records (which sort of defies the purpose of using the tool in the first place).
OWB is more of a ELT/code generator so if you create a similar mapping with a table and filter it will generate the SQL with the filter included. To be honest, I'm not 100% sure about this bit but I believe if you have a source via dblink (or even ODBC) then that full generated SQL should be sent to the source. In other words, although some people might be more comfortable with custom SQL I dont think it is actually necessary in most if not all cases.

How to implement QoS over UDP ?

Hi
Excuse me fo my poor english.
Is-it possible to implement QoS with java and socket UDP ?
Thanks

The term QoS means a number of different things. Which one do you mean? See here: http://en.wikipedia.org/wiki/Quality_of_service
Are you sure you want to use UDP? It is an unreliable protocol, and often takes quite a bit of work to use properly.
Also google for udp qos etc.

How to develop VoIP client using SIP in J2ME?

Hi Everybody,
I want to develop a VoIP client in J2ME that connects to asterisk server of debian and can call to the registered user of asterisk server and can have a telephonic talk session easily.
Do anybody have idea regarding the development of the client or having tutorial that teaches the development of VoIP in J2ME or in any other way.?
PLZ help me to provide the solution.
Thanks in anticipation.
with regards,
KHAKHAR SAGAR

Hi
I am interested about developing VoIP application (using SIP) in J2ME platform. But I am stuck with the problem of MMAPI. Without using MMAPI J2ME has no access to mobile media devices, such as speaker or microphone, and without creating a player MMAPI can't play media data, such as sound or video. But its not possible to record voice and play voice data simultaneously using player in J2ME. So it seems almost impossible to implement VoIP application maintaining all its constraints and requirements, specially in case of delay and jitter.
I am looking for some solution, which will provide the ability to overcome this problem. I come out with two possible solutions, but not sure about their out come. If we can develop a native media application, we can have access to it by using KNI (K Native Interface). In that way we can take some risk to develop VoIP application for J2ME. My another solution is, we can handle the player using MMAPI to record and play voice data in mill second level, so that we can have a real time feeling, though I am not sure if its possible by using RTSP.
If any one have solution of this problem, please help us.

VOIP over VPN need clarification

Hi,
Recently I have implemented Site-to-Site VPN between ASA and sonic wall firewall.
Problem: I can able to make call from ASA side(inside) Ip phone to sonic wall (inside) side Ip phone and vice versa and it’s ringing, But not able to hear voice. So I created VOIP over VPN configuration and applied appropriate service policy towards outside interface. But still I was not able to hear voice.
Tried below mentioned t’shot steps:
From ASA side we had two subnets (10.20.1.x/24 – Data and 10.20.2.x/24 – Voice ) and one subnet (192.168.x.x/24 ) from sonic wall side as interesting traffic ( lan to lan). When I configured site-to-site configuration on both ends my phase-1 and phase-2 came UP and can able to communicate between each other. (In interesting traffic I created two objects and bind those objects as one object-group for source i.e. ASA side lan subnet and one object for remote-Lan as destination)
My call manager is rest behind ASA and Ip phones needs to communicate from sonic wall side to inside ASA.
I can able to make call from ASA side(inside) Ip phone to sonic wall (inside) side Ip phone and vice versa and it’s ringing, But not able to hear voice. So I created VOIP over VPN configuration and applied appropriate service policy towards outside interface. But still I was not able to hear voice.
So, I done supernetting the data subnet and voice subnet into single network i.e. 10.20.x.x/16 at ASA side and applied the configuration changes (changed ACL, nonat rule, Voice QOS ACL accordingly), and I’m able to hear voice both end and I can communicate properly from ASA inside Ip phone to Sonic wall inside Ip phone and vice versa.
My question: I’m not understanding the logic how this supernetting resolved dead voice issue.
Pls clarify my question I’m bit confused on this.

It's not recommended. Although VPNs guarantee a secure pipe end-to-end, they don't guarantee latency and variations in latency (Jitter).

Solution: Gizmo VoIP over 3G/WCDMA with the Nokia ...

Copied from: http://www.elisanet.fi/~y639777/sipvoip
I have received some emails asking about how to get Nokia E-series working with Gizmo (SIP VoIP) over 3G/WCDMA.. So these are the steps that worked for me..
Steps:
1) first ensure that SIP VoIP is working over your wireless connection, ie following these instructions
2) disconnect from your Gizmo account if connected:
Nokia E51: Menu: Connectivity --> Internet tel. --> Options --> Disconnect from service
Nokia E71: Menu: Communications --> Internet tel. --> Options --> Disconnect from service
..then click "Back" and "Exit" until you get exit all the menus..
3) Find your default access point:
E51/E71: Menu: Tools --> Settings --> Connection --> SIP settings --> GIZMO VoIP (Not registered) --> Default access point
4) change you access point from your wireless network to 3G data connection, eg in my network the access point is called "internet".. then click "Back" and "Exit" until you get exit all the menus..
5) go back to the Gizmo account in Internet telephony:
Nokia E51: Menu: Connectivity --> Internet tel. --> Options --> Connect to service
Nokia E71: Menu: Communications --> Internet tel. --> Options --> Connect to service
6) Select your 3G data access point, it should be having a star and 3G label next to it
Notes:
- My wireless network is a simple configuration, basic ZyXEL ADSL box configured with NAT
- I know my operator doesn't block SIP VoIP traffic, additionally I checked this with a PC based SIP VoIP client
- My Nokia E-series device is not an operator variant. If you have an operator variant these features may be disabled in the firmware

Well I have found out that my 3G provider is not blocking ports. However, I have found that the issue only happens on that particular network, not others ..
I wonder if there are any setting I can change on my phone adapter that can help ..

Can't Figure Out How To Implement IEnumerable T

I have no problem implementing IEnumerable but can't figure out how to implement IEnumerable<T>. Using the non-generic ArrayList, I have this code:
class PeopleCollection : IEnumerable
ArrayList people = new ArrayList();
public PeopleCollection() { }
public IEnumerator GetEnumerator()
return people.GetEnumerator();
class Program
static void Main(string[] args)
PeopleCollection collection = new PeopleCollection();
foreach (Person p in collection)
Console.WriteLine(p);
I'm trying to do the same thing (using a List<Person> as the member variable instead of ArrayList) but get compile errors involving improper return types on my GetEnumerator() method. I start out with this:
class PeopleCollection : IEnumerable<Person>
List<Person> myPeople = new List<Person>();
public PeopleCollection() { }
public IEnumerator<Person> GetEnumerator()
throw new NotImplementedException();
IEnumerator IEnumerable.GetEnumerator()
throw new NotImplementedException();
class Program
static void Main(string[] args)
// Create a PeopleCollection object.
PeopleCollection peopleCollection = new PeopleCollection();
// Iterate over the collection.
foreach (Person p in peopleCollection)
Console.WriteLine(p);
Console.ReadLine();
That code compiles (basically because I haven't really done anything yet), but I get compile errors when I try to implement the GetEnumerator() methods.

The List<T> class implements the IEnumerable<T> interface, so your enumerator can return the GetEnumerator call from the list.
class PeopleCollection : IEnumerable<Person>
List<Person> myPeople = new List<Person>();
public PeopleCollection() { }
public IEnumerator<Person> GetEnumerator()
return myPeople.GetEnumerator();
IEnumerator IEnumerable.GetEnumerator()
return myPeople.GetEnumerator();
class Program
static void Main(string[] args)
// Create a PeopleCollection object.
PeopleCollection peopleCollection = new PeopleCollection();
// Iterate over the collection.
foreach (Person p in peopleCollection)
Console.WriteLine(p);
Console.ReadLine();

how to implement "sum(c) over(partition by a order by b)" in odi interface mappings

Hi
if you don't want to aggregate try to define a user function
analytic_sum($(value))
implémented by
sum($(value))
after that
replace your
sum(NOTICES) over ( partition by property order by RELAVANTDATE range between interval '30' day preceding and current row)
by
analytic_sum(NOTICES) over ( partition by property order by RELAVANTDATE range between interval '30' day preceding and current row)

How to implement this code in labview?

How do implement this pseudo code in labview? Please keep in mind "a" and "c" in the code below ARE VARIABLES
for i =0 to i=maxvalue
if i <= a
output = output2
else if i > a AND i<=c
output = output2
else if i < c
output = output3
else i = d
output = output4
I understance i can use a case structures and modify the label, but i do not know how to make the label dependent on a variable value.
Thanks

Try an array of boudaries and use threshold array. See this old example:
Now just iterate over an array of values using a FOR loop.

How to implement this need help

I created a datacontrol for a named query which (using Ejb entity beans) which accepted a employee id and click on find show me the respected employee details in a table.
case 1: In one single page
when i added the form consisting of a single text box , button and the table to show the result of the find method in one single page it worked out perfectly,,,
case 2 : using 2 different pages
But then i tried adding only the form in one page named page1 and and the table to show the result in another page i.e page2 , Also in the command action of find button of page1 i asked it to redirect to page 2 and show result . But it never showed me any results..
Question :
1) How to implement case2 i.e to have a form on one page and the resultant table to be show on another page i.e When users sees first page he adds the employee id in text box and clicks find .The user then needs to be redirected to page2 and the result of search should be shown in table...
Can anyone guide me over this... ???

Hi,
you use a method on the EJB that takes a argument (e.g. the employee ID). You then put the method result set on page 2 (the method argument shall be pointed to a request or session attribute using EL : #{sessionScope.EmployeeId}
On the search page - when the user hits the search button - you set the attribute "EmployeeId" in the session before navigating to the next page
