Opening a file with its filename from a servlet- avoid buffer to cach files

Hi,
I am building an URL with the following code and calling that particular file from this servlet using request dispatcher. When I am geting alcCode from getParameter method then it is not caching the pages
but when I am geting the same through a session value it starts caching the page after cirtain number of requests and shows up the previously requested file.
I guess it is because it always names the file with the package name.
for example if my package is sree then the file opened is named as
sree[1].pdf. Please help me solve this problem
alcCode = req.getParameter("alcList");
HttpSession userSession= req.getSession(false);//if request is from //submit action from a FORM
String alcCode;
alcCode = req.getParameter("alcList");
System.out.println("request.getparameter alcCode "+alcCode);
if (alcCode==null){
alcCode= (String) userSession.getValue("alcCode");
//else get the alc code from the session that has been stored
Calendar todaysDate=Calendar.getInstance();
int selectMonth=todaysDate.get(Calendar.MONTH);
int selectYear=todaysDate.get(Calendar.YEAR);
if(selectMonth <10)
//selectMonth = InvoiceDate.substring(1,i-8);
urlPdf="/reports/RPTS"+selectYear+"0"+selectMonth+"/PDF-FORMAT/E"+selectYear+"0"+selectMonth+"_"+alcCode+".PDF";
}else{
urlPdf="/reports/RPTS"+selectYear+selectMonth+"/PDF-FORMAT/E"+selectYear+selectMonth+"_"+alcCode+".PDF";
res.setContentType("application/pdf");
res.reset();
res.resetBuffer();
res.setHeader("Content-disposition","attachment; filename" +urlPdf );
System.out.println(urlPdf);
try{
ServletContext sc = getServletContext();
RequestDispatcher rd = sc.getRequestDispatcher(urlPdf);
rd.forward(req, res);
Thanks in advance.

I had a similar problem when I used the attachment argument to the Content-Disposition header.
try replacing this:
res.setHeader("Content-disposition","attachment; filename" +urlPdf );
with this:
res.setHeader("Content-Disposition","inline; filename=" +urlPdf );

I can't set Firefox to open PHP files with Firefox (in preferences- applications-php files) Firefox won't accept anything but "always ask" and Preview. I want to preview php files in Bbedit and that requires that Firefox can open it.

with an open php file in Bbedit (Macintosh) it was possible to preview appearance by chosing "Preview in.." in Bbedit's "Markup" menu. This called Firefox to open and display the file. Now, doing this continually repeats a "Open with (choose)" request.

Unfortunately this solution doesn't work for me for local files (on my computer). Still I can only choose to open in Notepad or "other". It seems that I can select Firefox, but it won't do anything when I actually select it.... I did NOT have this problem with the previous version of Firefox (before 6.0.2). The only thing that's changed, is the Firefox update from yesterday (September 28th, 2011).

Problem with opening a file in its application using Runtime

Dear experts,
excuse me for my ignorance, but I am facing a problem and I would really
appreciate some help. I am working on a java program in which I want the user
to have the ability to save the contents of a JTable into a file of his preference (the file could be of any type i.e xls, txt, doc...) and then open this file in its
default application (i.e the txt file through notepad, the xls file through excel etc..).
Everything works fine with the code below, if the filePath does not contain blank spaces. I did some search on the forun and the web, and also tried to
find a solution through the great link
http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html but I still
cannot solve the problem. Below I quote the part of the code (actually the actionPerformed dunction of the equivallent button) which is responsible for the opening of the file.
    excelButton.addActionListener(new ActionListener()
       public void actionPerformed(ActionEvent e)
         //saveFileName is the File that I want to open
         String filePath = "\""+saveFileName.toString()+"\"";
         System.out.println(""+filePath);
         try
          String cmd="cmd.exe /C start "+filePath;
          String cmd="cmd.exe /C start C:\\Documents and Settings\\test.xls";
          Process p = Runtime.getRuntime().exec(cmd);
         }catch(IOException ec){}
     });Thank you in advance for your help!
Sincerely yours,

Dear BillBlalock ,
thank you for answer!! You are very kind and helpful!! I would like to inform everybody that I have finally find another way of soilving my problem and I announce it to the forum in case somebody else encounters the same problem. Well, I soved the nproblem by using the following code:
    excelButton.addActionListener(new ActionListener()
       public void actionPerformed(ActionEvent e)
         String filePath = "\""+saveFileName.toString()+"\"";
         System.out.println(""+filePath);
         try
           String cmd="explorer "+filePath;
           Process p = Runtime.getRuntime().exec(cmd);
         }catch(IOException ec){}
     });I hope it can be useful to somebody!! By this code, I can make a button (in my case the excelButton) to open any file in its default application. Keep up the great work you are doing guys!!

Externally opening a file with the program its associated with

Basically I'm looking to simulate what would happen if you double clicked on something in a windows explorer window. I want to have the operating system open a file with the application that as associated with it.
how do I do it?

Have you considered the portability issue?
Win - Associate by editable user preferences
Mac - Associate to creation program
Unix/Dos - Explicitly associate program at command
Rather than just using exec, you could look into something encapsulated to set which program to use so you could use on other system.

I need to open a file with an associated programm.

I need to open a file with an associated programm.
I'm looking for two solutions:
1. for Linux/Solaris/Unix/...
2. for Windows 95/98/Nt/2000
For Windows I have done this with command line
Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler " + uSavePath);
but it doesn't work on windows2000. We need an universal solution.
For linux
Process p = Runtime.getRuntime().exec("netscape openURL " + uSavePath);
But may be anybody know better solution?

You are right. For unix better solution is that my program to care about all association itself. As I undestend now it's a common solution for unix applications.
But for windows it will be ugly enough. I've found another way for windows
Win2000/NT: "cmd /C start filename /B"
other Wins: start filename
for linux I've stopped at doing this via Netscape.
May be in future I'll make my property file.
start filename - on Win95(may be 98/ME) returns -1 if file not assotiated with a programm, and doesn't shows openWith dialog. It solved using something like "rundll32 shell32, OpenWith filename"
It's all for those how will solve this problem in future.

Opening a file in its native application from Flex.

Is it possible to open a file on whatever native application the user runs it as? Or even, at that, to simply open the directory it's in, in an explorer window?
We have a search application and the frontend is in Flex, and I'm trying to find a way to do this, such that when a use double clicks on a result (in a datagrid - but that's trivial), it opens the file or at least the location of the file on the OS.
Any system call where I can say system("explorer.exe " + filepath); or something?
Any help would be appreciated.

I can't open a file I just created a week ago and it says pages needs to be updated to open the file but its up to date

I can't open a file I just created a week ago and it says pages needs to be updated to open the file but its up to date, what do I do?

You have 2 versions of Pages on your Mac.
Pages 5.2.2 is in your Applications folder.
Pages '09/'08 is in your Applications/iWork folder.
You are alternately opening the wrong versions.
Pages '09/'08 can not open Pages 5 files and you will get the warning that you need a newer version.
Pages 5.2 can open Pages '09 files but may damage/alter them. It can not open Pages '08 files at all.
Older versions of Pages 5 can not open files from later versions of Pages 5.
Once opened and saved in Pages 5 the Pages '09 files can not be opened in Pages '09.
Anything that is saved to iCloud and opened in a newer version of Pages is also converted to Pages 5 files.
All Pages files no matter what version and incompatibility have the same extension .pages.
Pages 5 files are now only compatible with themselves on a very restricted set of hardware, software and Operating Systems and will not transfer correctly on any other server software than iCloud.
Apple has removed over 110 features from Pages 5 and added many bugs:

You can add the icon of the missing Pages on your Dock or open Pages from the Apple menu > Recent Items list.
Or you can archive Pages 5 so that it doesn't automatically open.
If you are unhappy about this review/rate Pages 5 in the App Store.

Copied that (.sdf) file to Desktop, and when I try to open with SQL Server 2005 management studio, its showing error "make sure the application for the file type (.sdf) is installed."
How can I open this file with SQL server?

Opening a file with FILE_SHARE_DELETE mode (Only on Windows)

Hi,
We have an application that imports logs from several 3rd party vendor's applications. Basically what we do is import the logs in real time, i.e we do have a live FileInputstream connection to the log file. Now, when the 3rd party applications that rotate these logs (many of them do when they grow big or scheduled periodically), all unix flavors dont see to have any problem, while the windows does complain that the device or resource is busy and the original application is not allowed to rotate it. When i dug into the native code of windows jvm, i found that the file is not opened in the FILE_SHARE_DELETE mode and only with FILE_SHARE_READ and FILE_SHARE_WRITE modes. When we wrote a separate C++ application the opens a file with FILE_SHARE_DELETE mode, we found that the logs are rotatable.
Now, how can we instruct the JVM to open a file with FILE_SHARE_DELETE mode? Is there any such implementation already or do i have to come up with another class extending the FileInputStream and use a totally different open method where the file is opened with this mode in the native code?
Thanks
Manava

Hello,
I think you can write :
Runtime.getRuntime().exec("start.exe " + MyFileDialog.getDirectory() + MyFileDialog.getFile());
So, "start.exe" choose the application (not valid for NT machine), ".getDirectory()" return the PATH and ".getFile()" return the NAME.

Can't open a file with spaces on the filename.

Lets say I have a file:
/home/orv/Open - Me - Please.txt
When I double click to open that file with any program, the result is something like this:
"Unable to find /home/orv/Open%20-%20Me%20-%20Please.txt"
I'm not sure what to call that process of converting the file name so I've been unable to google it up to find a fix or a way to change the behavior of the file manager.
I've checked the settings in Nautilus and nothings there. Any clues? Thank you!

I tried removing everything in my home directory to erase all settings, still the same problem.
I tried using a different file manager and still the same problem.
Here's another example of my problem and its quirks:
Lets say I have a file called:
/home/orv/I am a Movie.avi
In nautilus or thunar, double-clicking that file so I can play it with Mplayer will give an error:
Failed to open file:///home/orv/I%20am%20a%20Movie.avi
However, when I drag and drop using the file manager into Mplayer, it works.
So my problem is this automatic conversion of whitespaces into the %20 which I don't know how to turn off.

I am unable to open files on amything!!! a box pops up that asks me what do i want to open the file with..every time!! I want files to open when i click on them!! This happens with emails, websites, everything

I try to open attachments in emails and they will not open! A box comes up asking 'what do I want to open the file with', and it wants me to select from a list of options like - Firefox, IE, Word, Yahoo Browser. When I make a selection (usually Firefox) a new tab opens with a blank page! This always happens on attachments, links, websites......everything!

These files were lost two years ago.
That's not consistent with what you wrote in your first message. I can't help you unless I know what's going on. Either you do, or do not, have backups of all the data you want to keep. If you do not, then the first thing you need to do is back up those files. It makes zero sense to do anything else. In order to back up, you'll need either of two things: another Mac, in working order, with a FireWire port and enough space on its internal drive to hold your files; or an external drive, also with enough space.
On the other hand, if you do have backups, or if you simply don't care about any of the data, then the solution to your problem may be quite simple. All you have to do is boot from your installation disc (your profile says you're running Mac OS 10.5), erase your internal drive, reinstall the Mac OS, then restore your data from backup. You will need to be selective in restoring software, because incompatible software may be what caused the issue.
But it's also possible that you have a hardware failure, in which case you can't get your computer working again until it's repaired.
