JMF and X session

Hi All,
I am currently working on a XML-RPC related program which plays sound on the server using JMF. The funniest thing is that if I ssh to the server with X session enabled, for example, in linux, I go "ssh -Y root@server" and then run the program, everything works fine. However, If I just do a plain ssh without X session, the program returns me the error message as follows:
javax.media.NoPlayerException: Cannot find a Player for :file:/usr/java/jdk1.5.0_05/sounds/testsound.wav

I don't really have any idea about what's going on.
Please help. Any advise will be appreciated.

Thanks for the reply.
The ssh part is just part of my troubleshooting because that piece of program worked fine in Windows. Therefore I was suspecting that there is something to do with X or, JMF needs some graphical stuff. I'll probably put it into rc.local at the end once I get it working so whether ssh is fixed is not the main concern.
I don't really know what to check at the moment.

Under Excel Service Application --> session management; what is the difference between Session timeout and Short Session timeout?

Any call made from the API will automatically be set to the “Session Timeout” period, no matter
what. Calls made from EWA (Excel Web Access) will get the “Short Session Timeout” period assigned to it initially.

Problem with Frameset and page session

All,
I am having a problem with Framesets and page session attributes. I
have a client who's application uses a three frame frameset. They
have a requirement on several pages that when a button is pushed two
different pages load into the right and left frames. The way they
are accomplishing this is that on the pages were this is required,
they are adding target="_top" to the form declaration in their JSP.
Then they store the page names they want to display in session,
forward the request to the frameset, the frameset then determines
which pages to display based on the session variables. This works
exactly how they want it to.
Here is our problem. We need to store some information in page
session attributes. We have tried to get a handle to the desired
view bean and call the setPageSessionAttribute method. However,
since we are forwarding to the frame and the frame handles displaying
the desired JSP, that view bean we had the handle to is not the one
that is created to hand the display of the JSP.
The next thing I tried was to use the request object. In the
handleBtnRequest method, I set an attribute in the request object. I
then query the request object in the beginDisplay event of the view
bean. When the frame is reset the request object does not contain
the attribute that I have set. I'm confused by this because I
thought the request object would be available to me throughout the
life of the request.
Given the above information, does anyone have any suggestions? Also,
am I going about this in the wrong manner.
The client had been storing this information in user session, which
seemed to work. However, since the data being stored dealt
specifically with data for the requested page, we felt that storing
it as page session was more appropriate.
Thanks,

Screen Sharing and SSH sessions freeze occasionally on multiple mac minis

I have 28 Mac Minis at work. With such a large number of minis, I obviously can't have a monitor attached to each of them so I've got them plugged into a network switch and access them via Screen Sharing (both via regular Screen Sharing and ARD) and SSH sessions.
A few of them seem to suffer from intermittent problems however. I'll be using Screen Sharing when the session freezes. It may unfreeze eventually, but I can also usually just quit out and re-connect and it will be unfrozen. The same thing happens when I'm connected via SSH, it will freeze and I won't be able to type in any more commands.
I need help troubleshooting (or if anyone knows what could be causing this, that'd be cool too).
I've tried connecting from both a Mac Pro on the wired network and a MacBook Pro on the wireless network. The freezing seems to only happen on certain Mac Minis as well.
I've tried switching network cables from a Mac Mini that doesn't suffer from this problem with one that does and nothing changed.
I also thought it might be a bandwidth issue at first, despite being a gigabit switch connected via cat6 to the rest of our gigabit network, but even when no significant bandwidth is being used, the freezing still occurs.
One more thing I want to test is the connection between the switch all these Mac Minis is plugged into and one of the other switches that all our other network traffic goes through. I didn't set it up myself so I fear that it might be an old, damaged cable or something. Failing that, I have no idea what the problem could be, which is why I'm posting here.
So, does anyone have any idea what the problem could be? Or any other ideas for troubleshooting the problem? Thanks.
(They're all running 10.6.8, and range from Mid-2007 to 2009 models).

It would be in the system log. However, the next step would be to safe-boot in order to eliminate third-party system modifications. That goes for both client and server. If you can reproduce the problem in safe mode, then you probably have a network issue. Take everything offline except one client and one server, and test.

How to get stateful and stateless session bean in second jsp

I create stateful session bean in the first jsp, then how can I get the stateful session bean in the second jsp? I find that somebody store the bean in HttpSession.
If I store the stateful session bean in HttpSession, then I can get it in the second jsp. My problem is that I can store the stateless session bean in HttpSession, and get it in the second jsp. Then, both stateful and stateless can maintain the state in the second jsp. What is the difference between stateful and stateless session bean in this case ?
I understand the definition of stateful and stateless session bean, but I'm confuse how to use session bean. Can anyone provide sample jsp to show difference of stateful and stateless? How the stateful session bean can maintain the state for the client?

Greetings,
I create stateful session bean in the first jsp, then how can I get the stateful session bean in the
second jsp? I find that somebody store the bean in HttpSession.Which is the correct scope for sharing client-specific data when 'request' scope is insufficient.
If I store the stateful session bean in HttpSession, then I can get it in the second jsp. My problem is
that I can store the stateless session bean in HttpSession, and get it in the second jsp. Then, bothWhy is that a "problem"? Does your application not require the stateless bean to be shared? If so, then don't store the EJBObject reference in the session...
stateful and stateless can maintain the state in the second jsp. What is the difference betweenWhat do you mean by this exactly?..
stateful and stateless session bean in this case ?Statefulness of session beans is in regard to maintaining client state (er, in all cases). If your "stateless" bean is receiving information from the client (i.e. its caller) - either through a create method or a business method - and that information is available (retrievable from the bean) on subsequent method calls, then that bean is, in fact, stateful - regardless of how it is deployed.
I understand the definition of stateful and stateless session bean, but I'm confuse how to use
session bean.The correct question, it here seems, is "when" to use which type... Use a "stateful" bean when information about (from) the client (i.e. the caller) must be maintained across method calls of the bean. Use a "stateless" bean for general business methods that do not depend on "prior knowledge" of the client (i.e. the caller).
Can anyone provide sample jsp to show difference of stateful and stateless? How the statefulA "sample JSP" would yield nothing additional... The semantics of calling, using, and "persisting", bean references are always the same - regardless of type or class. However, the reason(s) for using one over the other depends entirely on the needs of your application.
session bean can maintain the state for the client?I recommend that you spend more time learning about EJBs generally. In particular, it seems you require more fundamental understanding of their scope and lifecycle. Refer to sections 4, 6, and 7 of the EJB 2.0 Specification.

JMF and Windows 7

I have a program using JMF which worked fine on XP and Vista but is behaving very oddly on Windows 7.
The program displays two mpg files synchronised with each other and I also control the playback speed. This has worked fine for 18 months.
On Windows 7 I still see two videos but the speed control doesn't work and one or other of the videos (appears random which one) splits vertically in the middle and I see it compressed both above and below the split. Is anyone else having problems with JMF and Windows 7?

The last version of Windows that JMF lists as supported is Windows 2000.
Most of the codec support in the Windows Performance Pack are native codecs, meaning they're precompiled DLL libraries. DLLs from one Windows version often times aren't compatible with any other Windows versions, so it's actually quite amazing JMF worked with XP or Vista, at all.
It sounds like what you're experiencing is simply DLL incompatibility using Windows 5 libaries on a Windows 7 system...

Hello,having a problem with Logic 9 on a Mac Pro.Working on a lenghty song and apparently session got corrupted.Doesnt let me export tracks,program crashes.Already tried start brand new session with the tracks imported into it but still wont export.Suggestions?

Thanks, Ian. Yeah, that's how I do it now...or with the controls in the left side pane. Still, I would have liked that quick on-the-spot edit capability...especially while sketching.
Ian Turner wrote:
Sorry Mark, you are out of luck as it does not do that - it works the same as L8. The way I would achieve that with more accuracy and control would be to route all the tracks you want to fade to a Bus then use volume automation on the bus. To do this you will need to add a standard audio track, then re-assign it using (Control Click on the track header) to the Bus track. You can then automate volume/plugins etc on the Bus track.

Javafx use jmf and capture audio device

Hello, I noticed a problem with the use JavaFX and Java Media Framework (JMF), in a project javafx call Java classes using JMF, but are not recognized PC audio devices, in fact when I executed 's the code CaptureDeviceManager.getDeviceList (null), displays the error: "could not commit protocolPRefixList", without recognizing any audio device. Instead I call if my application using JMF, outside of a JavaFX project, the devices are found and everything works properly, perhaps this problem depends on the security settings of JavaFX, or inability to use JavaFX is that jmf interfaces with audio and video devices?
thanks for the help

I'd use jmf and javafx but it was not for capture devices.
If you use jmf there are native libraries.
The thing i found was about the java.library.path wich is overriden when you start javafx that jmf can't load approriate libs.
Try to compare the System.getProperties for java and javafx then you should find where is the problem.

JMF and Darwin Streaming Server.

I have darwin streaming the sample files.
I use JMF to connect to darwin.
The connection is made, The server knows Jmf is connected , the server streams, verified with packet monitor.
The problem is that JMFStudio just does not start playing the video.
Any one know why, or have it working??

One strange thing I noticed, is that while monitoring jmfstudio transmit to jmfstudio across network,
I use ETHEREAL to monitor the packets, and ports being used. ETHEREAL usually just picks JMF RTP packets as UDP, which is right, but.....
DSS5 even though JMF is connected across lan to DSS5 the picture does not show.
WHile monitoring the packets, ETHEREAL picks the DSS5 packet s as RTP and every 20th RTCP.
So, what i am thinking is the DSS5 RTP packetizer is of better quality than JMF, and the result is that JMF is not fully aware of the 'true' specifications of RTP.
maybe......

V$BGPROCESS and V$SESSION

This is on 10g.
V$BGPROCESS displays information about background processes
V$SESSION has some rows representing background processes.
What is the difference between two ?
Am I correct in understanding that ; v$bgprocess contains total allocated processes whereas, v$session represents total runtime processes on that instance?
That being said, for example, if there are 10 sessions, all 10 sessions will have same number of bacground processes. Is that true?
To explain further, say if v$session displays DBW0 and DBW1, it means two instance of DBWR processes are running for this instance. But if v$bgprocess has DBW0.. DBW9 processes, that means, you can maximum have 9 DBWR processes on that instance.
Please concur if above is correct.
Thanks
R
t

it gives 157 rows, but in production it gives only 70 rows. Does this mean that maximum number of bg processes allowed are less on prod box than dev box?Your production database has 70 BG process, so its showing you this value.
The BG process can differ instance to instance, such as ARCH process, if archiving is enable for an instance, then you will have this one from your query, and you will not have this one where the archiving is not enabled.
You can set the PROCESSES parameter in DB, there is no parameter relate to BG process solely.
you would have the value of PADDR=00 for the inactive BG processes.
Those BG processes are active will have a value of PADDR which is the address of the process state object.
Look at below :
you will find that PADDR !='00' from v$bgprocess retrieve the same columns as querying the v$process and v$session by joining and have the PADDR=value/not 00, that is the active BG processes

Why not jdeveloper creates the persistance unit and the session client and

why you do not create the persistance unit (outside) and the session client and ...the interface and other required opjects automatically when I create the application or the project?
why you are using symbols like AFD, JSF, JSP, JPA,.JEE...and tens more, why you do not use a meaningfull names of these process symbols.
Thanks
Ali

Asalman,
I'm quite happy the JDeveloper behaves the way it does. Why? Because in most of my scenarios I don't want to be driven in a particular direction of development. This my choice of development and I don't like tools that dictate this to me.

Not able to recognize any video/audio devices using jmf and java soun

Hi ,
I need one help from your side.
Here I am expecting some clarifications from you. Before that let you my environement.
My working environment :
Eclipse tool and added jmf jar to my project I did not do any thing more.
If any thing I need to do just let me know. My target platform is MAC & UBUNTU.
Please bare with my questions.
1) I am not able to recognize any video/audio devices using jmf and java sound APIs on My system.
( I checked with the app mentioned in the http://www.java-forums.org/new-java/11201-jmf-cannot-connect-device.html )
Do we need any administrives rights for our working PC.
What is the procedure/ setup I need to follow from a java application to enable particular audio/video device since I dont about end-user system setup right.
If possible send some sample code to recognize /r detect audio device ( voice input ). It should run on both MAC and UBUNTU.
2) I run the one sample audio recording application of this link (http://www.jsresources.org/examples/SimpleAudioRecorder.java.html) which is provided by YOU.
I got output audio file and able to hear voice on UBUNTU system but not able to hear voice on MAC system.
I heared that default line in ( audio setup of the sys) is wont take any voice data on MAC.Why I made this stmt means we are getting false when using isSupported methods of JAVA SOUND API.
( like for TragetdataLine ...i,e, all ports are getting false)
I have one sample audio recording app implemented by QUICKTIME API. In this case also he taking audio ftom device only using quicetime API.
With that we are able to record and hear audio ( voice input --> not line in , external device we added some thing like SSB...)
3) In case of Video capturing DataSource, Streams are implemented by PullBufferDataSource , PullBufferStream intefaces used.
In case of Audio capturing DataSource, Streams are implemented by PushBufferDataSource, PushBufferStream intefaces used.
Can you explain the reasons ? I gone through API but i am not clear.
HOPE I WILL BE CLARIFIED EVERY THING FROM YOU.
Thanks
