Runtime.exec() is not parsing properly when a argument contains space

Hi,
Runtime.exec("a.exe hai \"how r u\"); to execute a sample application...
In windows the argument received by a.exe are as follows:
hai
how r u (as a single argument)
In Solaris the argument received by a.out are as follows:
hai
"how
r
u"
Why it's happening this way??
using jdk1.5_08
Note: using processbuilder is not possible as of now..
Thanks.

folks thanks for your reply..
But I think will not solve my problem. These things
will surely work, but our customer have this running
in the their work place and facing this problem only
in solaris and not in windows.. so we can fix this in
the next release.. but want could be the solution now
!You could prefix the command with "sh -c " so that the shell is active once again but on some shells this does not work. Must be worth a try.
>
We need to give a reply to them, saying whether it is
our bug or a problem in Java API since it's working
fine in Windows.Behind the scenes, Windows (or really DOS) has created frigged version of the Unix 'C' exec() calls library so that they behave similar but not the same a the Unix version. I suspect Java just uses this library.
>
Question : Why passing whole command with argument as
a single works in windows and not in solaris/unix ?
Can I conclude and say this is due to a bug in Java
API?Definitely NOT.
Edit : I have been racking my brains and I think you need the command string to be
"sh -c \"YourExecutable hai \"how r u\"\""
because the -c option says treat the next argument as a command to the shell.

If after you charge it for about three hours and it only last about five minutes the battery is probably dead or there could be another hardware problem. I would go back to the Apple store and ask them specifically how can it be OK if the fully charged battery only lasts five minutes.

Clip inspector in imovie not working properly - when I select a picture - and select clip adjustment it tells me that I need to select one or more clips to view Inspector tools and in a clip the audio adjustment only shows a speaker? help

Clip inspector in imovie not working properly - when I select a picture (in project library) - and select clip adjustment it tells me that I need to select one or more clips to view Inspector tools and when I select a movie clip and then click on audio adjustments the audio adjustment appears as a speaker icon and I don't know how to get to the various audio options? It was working fine one minute and then I seemed to lose the functionality. Also editing a photo in a photo or getting rid of ken burns effect etc does not seem to work. help

Can anyone shed any light on this as I am having the same problem? One minute it works fine, the next you get the error message above.
Many thanks.

Thanks for that information!
I'm sure I will be calling AppleCare, but the problem is, they charge for the phone calls don't they? Because I don't have money to be spending to be on the phone with a support service.
In other things, it seemed like the only time my MacBook was working was when I had Snow Leopard without the 10.6.8 update download that was supposed to be done to prepare for OS X Lion.
When I look at the information of my HD it says that I have 10.6.8 but that was the install that it claimed to have failed and caused me to restart resulting in all of the repeated problems.
Also, because my computer is currently down, and I've lost all files how would that effect the use of my iPhone? Because if it doesn't get fixed by the time OS 5 is released, how would I be able to upgrade?!

Hi bunjamin,
just go to BlackBerry World, and update all your apps including BBM.

you can turn off the magnifying glass :
device settings >> accessibility >> magnify mode >> OFF
you can deactivate the "reset to Hub view" :
hub >> overflow (bottom right button) >> Settings >> Display and actions >> Return to Default View When Idle >> OFF

why is that we insist on seeing the source file ?
There is no one way of doing things in flash and no one can
help
you based on "does not work description".
This is way to broad of a subject to even try to guess.
Same as asking "my car does not work, what's up with
that"....
Please upload the problematic file and provide url for us to
check.
Otherwise you need to try to troubleshoot it yourself as we
can't
guess from here what possibly is wrong with that file.

Application does not work properly when I press a CommanButton

Hi all, I am having a problem with weblogic 10.3.5.
It turns out that an application built with JDeveloper 11.1.5, I test it, and everything goes well in the JDeveloper integrated Weblogic.
But when deploy in a standalone weblogic 10.3.5 server, the application does not work properly when I press a CommanButton to go to another page search (the property "action" is set correctly) , but nothing happens, stays in the same home page. Similarly when a commanButton link to run a task-flow, It do not work , however in the JDeveloper integrated Weblogic it runs correctly.
How I can solve these problems?
Thanks.

Thanks Frank for help us, but when I writing this comment we are doing at home. So, we going to test the page in a stand alone weblogic server 10.3.5. We wrote the URL as :
" http://<our ip>:7001/myApp/faces/index.jspx "
this application contains a report desing and compiled with iReport 4.5.1 ( last version in the moment ), we can see the report when I press a commanButton without any problem.
But now, we need try your suggestions in the office, and give you more information about it . Thanks for the moment.
In the Afternoon we gonna give you more information about it .

Why do the youtube clips not expand properly when I double click on the page

why do the youtube clips not expand properly when I double click on the page

The exclamation mark is telling you that iPhoto has broken the file path/link to the original file. Assuming you're using iPhoto 9 or later Apply the two fixes below in order as needed:
Fix #1
1 - launch iPhoto with the Command+Option keys held down and rebuild the library.
2 - run Option #4 to rebuild the database.
Fix #2
Using iPhoto Library Manager to Rebuild Your iPhoto Library
1 - download iPhoto Library Manager and launch.
2 - click on the Add Library button and select the library you want to add in the selection window..
3 - Now that the library is listed in the left hand pane of iPLM, click on your library and go to the Library ➙ Rebuild Library menu option.
4 - In the next window name the new library and select the location you want it to be placed.
5 - Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments but not books, calendars or slideshows. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.

Actually i simply want flip card animation which is not working here in my code. When i tapped button to invoke animation its behavior not exactly flipping. Its one side work properly but other collapsed suddenly not rotate if i keep mouse right at
the button, but if i change mouse pointer at that very time after tapping it works properly. Mouse Pointer Over mean screen points where i tapped.
Triggered Function is here:
private void btnChangCase_Tapped(object sender, TappedRoutedEventArgs e)
if(isCaseChanged==false)
isCaseChanged = true;
FlipOpen.Begin();
else if(isCaseChanged==true)
isCaseChanged = false;
FlipClose.Begin();
