How to use JMF in p2p system ??

I want to develop a system about p2p stream,and I use the jmf as the client.
could you guys suggest me ?? and provid some material to me ??
PLEASE !!!!

Find on the net AVReceive2, AVTransmit2, AVReceive3, AVTransmit3 and RTPSocketAdapter Java source files. Just search in google or yahoo, for instance, they are available everywhere. These are the the most used when beginning to work with JMF. Number "3s" are actually the ones you might be looking for. Something like p2p video/audio streaming.
Hope that helps

Hi Captfoss!
I fixed it but now I have another problem. My application send me this message:
Cannot initialize audio renderer with format: LINEAR, Unknown Sample Rate, 16-bit, Mono, LittleEndian, Signed
Unable to handle format: ALAW/rtp, Unknown Sample Rate, 8-bit, Mono, FrameSize=8 bits
Failed to prefetch: com.sun.media.PlaybackEngine@1b45ddc
Error: Unable to prefetch com.sun.media.PlaybackEngine@1b45ddc
This time the fail is prefetching. I have no idea why this problem is. Could you help me?The system cant play an audio file / stream if it doesn't know the sample rate...somewhere along the way, in your code, the sample rate got lost. Sample rates are highly important, because they tell the system how fast to play the file.
You need to go look through your code and find where the sample rate information is getting lost...

How to use BPM itegrate different system aysnchronously

for example, 3 enterprise applications need to be integrated together with BPM, which are Bid system, ERP system, Finance system,
and erery business document should be approved by persons one by one in the 3 different application system with its workflow respectively, we can't change the workflow in the
different system, and only when the document is finished approved in the BID system asynchronously, it can enter the ERP system, an so on .
after the business document is approved in the Bid system, it should be returned in the BPM contexts,and the BPM user will dicide whether it will be enter the next system.
so how to integrate the 3 application system?
I draw a[ BPM process|http://www3.picturepush.com/photo/a/2586651/640/Picture-Box/aaa.jpg], but in this process, the "ERP human activity" activity, this activity how to get data from the "BID system asyn workflow" which is an asynchronized
wrokflow?

Gavin,
For asynchronous cases, you should adopt the "wait and trigger" principle. In BPM, you can acheive it by using a timer and an automated activity. Set the timer repeat time to say 15 mins (you should change it as per your business scenario), and then execute / trigger an automated activity, which will call your Bid system to check the state (whether the data entry / specific workflow is over). If the state is completed, (you may check using exclusive choice), move to next step. Else, pass back the control to timer which will again make the process wait. This way the objective could be attained.
Hope this helps.

How to use a portal jdbc system to delete or insert by IExecution.execute

hi everyone:
I create a jdbc system in portal. Then I use following codes to query a table
IQuery query = client.newQuery();
query.execute("SELECT * FROM [Categories]");
It is fine.
Now, I wanna do insert or delete operation. I can't use the IQuery object. I think it is only for query and it is Deprecated. I find there is a method: IExecution.execute(IOperation). But I don't know how to use that method. Can I insert/delete records using that method? The last question is how to control the sql transaction by that IExecution object.
thanks
elliot

Hi,
I followed the interface framework to complete a query.

How to use AET in a system without any masterdata?

Hello,
we know how to use the AET in general.
But we have a developmentsystem where it is not allowed to create masterdata or documents.
Therefore it is not possible in this system to open for example an existing customer in WebU and enhance a new field to BP_HEAD\details for example.
Is there a way to use the AET without having master data available in the dev-system?
Thank you.
Kind regards
Manfred

Hi,
thank you for this very helpfull answer.
This works for the most components like BP_HEAD.
It does for some reason not work for component ERP_H.
"Exception during toolbar processing".
The component is displayed but without buttons - also no configuration button for AET.
Any ideas.
Kind regards
Manfred

How to use JMF in ipv6?

I wrote a program that can run in ipv4. But when I change the IP address from a IPv4 address to a IPv6 address, it doesn't work any more. Do I miss anything? Is there something else I should do to make it work in IPv6?
p.s. I can have my program contact server with a IPv6 address using only socket, but I can't do that using JMF. Why?

I have never tried doing what you are soing so I am just thinking aloud. I think that using datamerge for this is going to assign the same ID to the fields, which is why the checkboxes are filling when selecting one of them. Open the PDF in Acrobat to check it though.
Another thought. Are you merging to a new document or direct to PDF? If going direct to PDF, try creating the merge document first. If that doesn't work, I think it will be the field IDs being also replicated. If so, then the only course of action would be either manually changing them in Acrobat, or an ID script and or an Acrobat script. Neither of which I have heard of. But if they do have the same IDs, then I would inquire in both the ID scripting forum and the Acrobat forum.
Good luck. Interesting use of datamerge. I hope you find a suitable answer.
