Finding all the running instances of JVM

We have to write a tool to upgrade an existing installation of our Java based application. For that we need to determine whether our java application is running.
1. One way which I don't find that clean is listing all the processes on the machine and then find my application.
2. Other option is using jps, but it is part of JDK and not jre, so that rules it out.
Does java provide anything inbuilt to find all the running jvm on the host(something like jps)
Thanks,
Sumit

How we can find out the running window application ?

hi all,
how can i find out the running windows application through my java program?
if anyone know any methods or classes please inform me soon...........
one way to ask is "how one can trap the running window's application through java code"?
Please do inform, if you have any valuable guidelines to achieve this
Thanks in advance

I pretty sure this isn't possible. You could write something which uses JNI to call native methods, but you'd have to have methods avaliable to call. So suppose you wanted a process on a Windows machine to read the text in an instance of IE's address text box you'd first need a way to do this with Windows specific code. And I can't think how you'd do that - unless you are directly interacting with the OS. So I'm afraid there is no easy way to do this in Java, and even the very difficult way with JNI may not even be possible.

Satellite Pro L40 PSL43E I need to find all the XP drivers

I need to find all the XP Drivers for this particular notebook. Any ideas where i can find them. on this site i only get the "how to downgrade" Pease Help ASAP

If such drivers are available then you will be able to find such drivers on the Toshiba European driver page.
If the drivers are not available on the Toshiba European driver page, then the drivers were not released.
But Ive got one hint; I found some XP drivers for Sat L40 series. Some series supports the same devices and therefore the drivers should run too.
Check some single XP drivers from different L40 series and maybe it would run.

Finding out the deleted instance from a recurrent set of events

Good Morning,
We have a requirement to find out all the events which belong to a uid in a recurrent event. When the event is created the RRULE returned is:
RRULE:FREQ=MONTHLY;BYMONTHDAY=16;COUNT=6;INTERVAL=1;WKST=SU
I then change the date of one of the instance in the event and the rrule and rdate are returned as follows
RRULE:FREQ=MONTHLY;BYMONTHDAY=16;COUNT=6;INTERVAL=1;WKST=SU
RDATE:20060717T060000Z
I then delete one of the instance and there is no change in the properties rrule or the rdate.
Is there a way to find out the deleted instances in the recurrent set while doing the fetch on the calendar.
Best Regards
Joyce

Good Morning,
We can use the EXDATE and EXRULE property to get the events in exception.
Thanks
Joyce

To get list of all the running applications

Hi all,
Hey can anyone tell me how i wil get list of all the running applications on windows using java?

Cant it be done even using Runtime.exec()?Well, sure. Assuming there is a command-line program
that does what you want. But then your question is
"What can I run at the Windows command line to get a
list of all the running applications?" and (I am sure
you will agree) this is nothing at all to do with
Java programming.
I completely agree... I just find it amazing that this guy knows exactly what he wants to do but is unable to point a web browser to a search engine, type in what he wants to do the read the resulting pages.

My Top Rated songs, when I synch my iP4S - comes up with an error message saying it can't find all the songs. When I check, library has songs listed but with a "!" bubble next to them. When I click on them they play. What am I doing wrong?

When synching, itcomes up with an error message saying it can't find all the songs. When I check, library has songs listed but with a "!" bubble next to them. When I click on them they play. What am I doing wrong? This happens every time so I click them and it sorts them (boring with 200 odd). How can I prevent this?

Once you successfully add you iTunes library to iTunes Match, you go to Settings>iTunes & App Store on your iOS device and turn on iTunes Match. Your iTunes Match library will then appear on your iOS device.

Can I get a List of all the running processes in the system using java ?

I want a complete list of all the Running processes currently in the system.
List of running processes is like, in MS Window environment while we presses ctrl + alt + del and we get a small window containing a list of all the running processes currently in system.
I hope somebody have done the same and will help me.
thanx.

Here is the sample code to get All running process in your system .
Its in C++.And you have use JNI to use this code.

How to find all the tables associated for a particular transaction

Hi-
May I know how to find all the tables, related(foreign key) tables for a transaction within SAP GUI?
Up to my technical knowledge, this can be achieved by looking database diagrams from DB level. But that would be for entire database as a whole. What I'm expecting is to see transaction level relative tables that too from SAP GUI. Please share the possibilities if any.
Regards
Sekhar

Dear Micky Oestreich
May be we possess expertise or high level experience, it should not show up in our way of communication. Every professional starts with the basic stuff to learn. When the question is raised in such minimum polite way, the same level of courtesy is expected in return. If you felt my question was basic, you might have refused it gently. If you are in good mood or bad mood it doesn't matters.
Hi Vengal Rao
Thanks for your response. It helped me.

How to find all the parts used from stock for 1 machine

Dear Sap community,
I'm trying to find all the spare components that are used for 1 specific machine.
If I look in the work orders under components it only gives the components that are orderd.
But I would like to find the components that come out of stock. I asked the stockkeeper and he said he writes it all in the work orders but we can't find it back.
It would be nice to just find it on the work order but it would be easier if I could just choose a machine and then find all the spare parts used from stock.
So my question is can I find all the spare parts used for 1 machine or just find the spare parts in the work order?
Thank you for any help you can provide in this situation,
Michael Claes

Report/FM to find all the tasks involved by an agent

Hi,
Is there anyway to find all the workflows/tasks involved by one user in the system. I want to route all those work items to different user.
Thanks
Swamy

Hi,
1) Set up a substitution between the users with report RMPS_SET_SUBSTITUTE. => Set up the substitute for the person (user1) who left the company.
2) Fix the sitution. If the wrong user (user1) is still getting work items, try to find out why, and then do the necessary changes in master date or whatever, so that the new user will start receiving the work items.
Regards,
Karri

Is it possible to find all the documents for a serial number ?

Hi all,
I'm using materials with serial numbers in complaints.
Is it possible to find all the documents for this serial number ?
Is it possible to check if this serial number is allready in use in any document ?

Hi Mengelkemier,
I think you're posting in the wrong forum. This forum is intended to be used to discuss virtualizing Exchange Server on the the vSphere platform. The question you're asking seems to be a mobile device specific question.
You would probably get better visibility posting on a forum dedicated to your particular device. And for what it's worth, some devices will let you sync all of your email and others will only let you sync a certain amount. It's dependent on the device you're using.
Good luck in finding your answer.

Why can't iTunes find all the album artwork?

Why can't iTunes find all the album artwork?

That would fall under Browsing History. Firefox > History -> Show All History
Firefox doesn't use Temporary Internet Files for anything except Windows Media files.
Type '''about:cache''' in the URL bar and hit Enter. <br />

Finding all the Purhcase Order if we have the Material Number

Hi Gurus,
In 2009, we set up the Purchase Orders for particular material with standard cost, now in 2010 the vendor has changed the standard cost of the material,however in our books we did not change the standard cost in the PO.
Now we want to change the standard cost in all the purchase orders at once. is there any way to find all the purchase orders against any particular material, so that we can update the Purchase order.Actually we are not aware how many purchase orders have been created for such material.
Thanks

Dear,
Use transaction ME2N and find the purchase order for particular material or material group..
