Problem in using JFileChooser

Hi all
i m using JFile chooser
here is the code:(at class level)
private JFileChooser fileChooser = new JFileChooser(){
protected void fireActionPerformed(String command) {
if (command != null && command.equals(JFileChooser.APPROVE_SELECTION)) {
super.fireActionPerformed(command);
when i open the form, following exception arises.
java.io.IOException

     at sun.awt.image.ImageFetcher.run(ImageFetcher.java:136)
however it is not hindering my work, but why it is...
Pls help

Hi all,
I think no one in the bord knows the answer.
or the problem is so trivial that, no one want to reply.....

Problem using JFileChooser

Hi,
I am encoutering a strange error dialog, javaw.exe No-Disk dialog box with this message "There is no disk in the drive. please insert a disk in drive A" when using JFileChooser.
I have been referring to some forums and understood this is a bug. But most encountered this when they are using it with Java Web Service or some web application.
I have Windows 2000 and mine is a java application. I have tried a workaround with WindowsAltFileSystemView but that does work with Windows 2000.
So is there any workaround..help needed.
thanks.

If you do not do so already, try setting a starting point for your JFileChooser.
JFileChooser chooser = new javax.swing.JFileChooser();
chooser.setCurrentDirectory( someDirectory );The "someDirestory" could be any directory you want or need depending on Platform independance or not.

Problem with the JFileChooser

Hello all,
I'm having a small problem with the JFileChooser, the thing is whenever I click the cancel button in the dialog box a NullPointerException is thrown, so does anyone know wut is wrong?

Either way, it's an extremely important skill to learn to read the API and become familiar with the tools you will use to program Java. Java has an extensive set of documentation that you can even download for your convenience. These "javadocs" are indexed and categorized so you can quickly look up any class or method. Take the time to consult this resource whenever you have a question - you'll find they typically contain very detailed descriptions and possibly some code examples.

RMI -How to use JFileChooser to see remote computer FileSystem

i hav made a program in RMI which uses JFileChooser to show remote-machine File System. i have made my own FileSyatemView class (MyFileSyatemViewClient which extends FileSystemView) and override all the methods of FileSystemView Except getFileSystemView.
Similarly i have made my own FileView(MyFileViewClient).
i fed these to the JFileChooser. And object of JFileChooser i am recieving from the server through remote method getFileChooser(). Thus the code is like:
                         MyFileSystemViewClient mfsvc; //Defined Globally
                         MyFileViewClient mfvc; //Defined Globally
public void actionPerformed(ActionEvent ae)
if(ae.getActionCommand().equals("Open"))
                         mfsvc = new MyFileSystemViewClient();
                         mfvc = new MyFileViewClient();
try
JFileChooser jfc=fi.getFileChooser();
// "fi" is the FileInterface through which we access server-side methods.
                              jfc.setFileSystemView(mfsvc);
                              jfc.setFileView(mfvc);
                              int retval = jfc.showOpenDialog(null);
                              if(retval==JFileChooser.APPROVE_OPTION)
                                   getf = jfc.getSelectedFile();
                         catch(Exception e)
                              System.out.println("Error Occurred In OPEN :"+e);
MyFileSystemViewClient class looks as :
public class MyFileSystemViewClient extends FileSystemView
               public MyFileSystemViewClient()
                    //super();

//.....................................................End of the MyFileSystemViewClient.......................
Thus each method in the class MyFileViewClient brings the required information from the server. BUT we are getting two problems:
1) so many folders at the server-side are shown as files in the dialogbox.
2)dialog box shows all "folders of the desktop" of the local filesystem and some more "local drives without any name". when i click a folder in the dialog box which is on my local machine, nothing happens. they are just the icon with the name but don't show the content. although i can easily see the drives of the remote filesystem and browse through except for the problem stated above at no.1.
ok guys now its your turn to speak up.....
plz give some suggestions and comments..
ciao!!

sry to all friends there who can't read the code clearly. as per the suggestion i am putting the code afresh..
the main client class which binds to the server contains following piece of code :
MyFileSystemViewClient mfsvc; //Defined Globally
MyFileViewClient mfvc; //Defined Globally
public void actionPerformed(ActionEvent ae)
     if(ae.getActionCommand().equals("Open"))
          mfsvc = new MyFileSystemViewClient();
          mfvc = new MyFileViewClient();
          try
               JFileChooser jfc=fi.getFileChooser();//Requesting JFileChooser object from server.
               // "fi" is the FileInterface through which we access server-side methods.
               jfc.setFileSystemView(mfsvc);
               jfc.setFileView(mfvc);
               int retval = jfc.showOpenDialog(null);
               if(retval==JFileChooser.APPROVE_OPTION)
               getf = jfc.getSelectedFile();
          catch(Exception e)
          System.out.println("Error Occurred In OPEN :"+e);
}i again like to convey that, "fi" is the FileInterface through which we access server-side methods.
MyFileSystemViewClient class looks as :
public class MyFileSystemViewClient extends FileSystemView
               public MyFileSystemViewClient()
                    //super();
                    try{
                    fi.invokeMyFileSystemViewCons();
                    }catch(Exception e){
                         System.out.println("Error in invokeMyFileSystemViewCons : "+e);
               public File[] getFiles(File file,boolean tr)
                    try{
                    return fi.getFiles(file,tr);
                    }catch(Exception e){
                         System.out.println("Error in getFiles : "+e);

Using jfilechooser

hi all,
how to use jfilechooser to select a file available in another computer of my LAN.
i used setFileSelectionMode(JFileChooser.FILES_ONLY);with this statement, if i give 'c:' or any local/mapped drive names in text box, it lists the files properly and i can choose the file.
but, if i give the IP address of another system, i.e like '\\192.168.0.243', it simply accepts this (\\192.168.0.243) as filename and closes the file chooser dialog. if i type the ip address, the file chooser should list the shared drives in that system. how to do this?
i tried java.awt.filedialog, but it does this, but supports only single file selection
thanking you.

Cross-posting is really rude, it means that you don't care about the time that people spend answering questions. Most frequenst posters at all forums and mailing lists will tell you that.
Cross-posting and not saying in the post that you are cross-posting is even worse. (Cross-posts are often removed from these forums).

Most frequent posters would have done that if they had found out that you were cross-posting. The only mistake that Darryl did is that he thought that you were going to listen to his advice even if he didn't make that specific post as a moderator.

The warranty for the iPhone is not and has never been International.
Warranty and support are ONLY valid in the country of origin. The only exception is the EU where the entire EU is treated as one country.
If the device will be used in India, buy it in India.
An unlocked iPhone will work on any supported GSM carrier world wide. The LTE portion of a US purchased, unlocked iPhone is unlikely to work outside North America as it does not support the appropriate bands used in other countries.

Problem on using Crystal Report Viewer on windows application ("specified type is not valid ")

Hi
I am having problem on using Crystal Report Viewer on one of my windows application.
I am not sure how to put the Crystal Report Viewer 11 Control onto the tool box.
I could found a Crystal Report Viewer control on my computer, but it is version 8.5.
I have also found another one which is Called Crytal ActiveX Report Viewer, i don't think it is the one I can use. As when I try to load a dummy report on to the Crytal ActiveX Report Viewer, It return an error. "specified type is not valid"
Please see the Code sample below.
private sub loadReport()
     Dim r as New ReportDocument
     'v is the name of the Crystal ActiveX Report Viewer Control
     r.Load("C:\Report1.rtp")
     v.ReportSource(r) <---It throw error on this line.
End Sub
Could you give me some advice about what have I done wrong, How to check if I have set up the Crystal Report Component correctly in my Visual Studio 2005 Standard edition.
Thanks in advances.
Many thanks
Chi

VS 2005 Standard and Express editions do not come with Crystal Reports; only the Professional and higher editions will have CR bundled. However, I believe you can purchase CR XI R2 Developer and it will give you the components you need to create a VS .NET 2005 application using the Standard edition.

Here I want to fetch Material PO text in Material master to my report.
I just dont know in which field of table "it_thead" the actual text is available.\
I tried debugging the program but was not successful.
I have also tried using READ_TEXT but it gives an error if no Text exists.
    CALL FUNCTION 'SELECT_TEXT'
      EXPORTING
        client     = sy-mandt
        object     = 'MATERIAL'
        name       = wrk_matnr
        id         = 'BEST'
        language   = sy-langu
      TABLES
        selections = it_thead.
How do i print the actual MAterial PO text in IT_THEAD ?
hope u understand the question...please do let me know if any details are required from myside..

Hi,
My mistake.
Check below sample code.

    INPUT         = po_matnr
IMPORTING
   OUTPUT        = po_matnr
MOVE po_matnr TO l_matnr.
CALL FUNCTION 'READ_TEXT'
EXPORTING
*   CLIENT                        = SY-MANDT
    ID                            = 'BEST'
    LANGUAGE                      = sy-langu

IF SY-SUBRC <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

ENDIF.
LOOP AT i_lines INTO wa_lines.
WRITE: /1 wa_lines-tdline.
ENDLOOP.
Just execute this code by inputting ur material number.
If the text doesnot exist the error u r getting because of not commenting the MESSAGE statement after FM call. Try in the way i told above.
Thanks,
Vinod.

I have two Iphones with different email addresses sharing one Apple ID. Will that cause problems with using messaging and FaceTime?

I have two Iphones 5 with different email addresses sharing one Apple ID account.Both are using IOS 8.
I would like to set up a new Apple Id for one of the phones and remove it from the old account.
If I do that, can I move all of the purchased apps and songs to the new Apple account?
Also, will sharing one Apple ID account with two devices cause problems with using messaging and FaceTime?

Sharing an iCloud account between two devices can be done without causing issues with iMessage and FaceTime, just go into Settings for each of these functions and designate separate points of contact (i.e. phone number only, or phone number and unique email address). While that works, you'll then face the problem where a phone call to one iPhone will ring both if on the same Wi-Fi network -- but again, that can be avoided by changing each phone's settings.
Rather than do all that, don't fight it -- use separate IDs for iCloud. You can still use a common ID for iTunes purchases (the ID for purchases and iCloud do not have to be the same) or you can use Family Sharing to share purchases from a primary Apple account.

No. purchases are forever tied to the apple ID used to buy them. Delete them and buy your own copies.

Problems in using database link

Hi all,
I have problems in using the following created database link:
Name: fzanalyze
User: fzanalyze
PWD: xxx
Host: fz.domain.com
I get the following error message, if I try to start this select:
select * from tab@fzanalyze;
FEHLER in Zeile 1:
ORA-12154: TNS:Couldn't resolve service name
The problem, the TNS is correct, because I copied the hoststring from the tnsnames.ora. Also I can connect to the database by using the given hostname as follows:
connect fzanalyze/[email protected]
connected
What could be the problem, the I get the tns-Error, although I can connect normal to the database??
Thanks for helping
Dana

Dana,
Unlike Kamal, I don't use SQLNET anymore (isn't it obsolete from 8i+?), so I don't have any sqlnet.ora on my client or server.
I'm not really a sysop, so no clever thoughts behind the following ideas, I just use these for development purposes at home:
IP range at home = 192.168.x.x segment (another router server connects to the internet)
Oracle server computer name = dbserver.seinpost.nl (local address = 192.168.1.110)
instance entry in $TNS_ADMIN/listener.ora @ server:
    (SID_DESC =
      (GLOBAL_DBNAME = inst04.seinpost.nl)
      (ORACLE_HOME = /u01/app/oracle/product/10.1.0/db_1)
      (SID_NAME = inst04)
    )instance entry in $TNS_ADMIN/tnsnames.ora @ server:
INST04.SEINPOST.NL =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = dbserver.seinpost.nl)(PORT = 1521))
    (CONNECT_DATA =
      (SERVICE_NAME = inst04.seinpost.nl)
)instance entry in tnsnames.ora @ client:
INST04 =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS =
        (PROTOCOL = TCP)
          (HOST = 192.168.1.110)
            (PORT = 1521)
    (CONNECT_DATA =
      (SERVICE_NAME = inst04.seinpost.nl)
)So again, no sqlnet.ora and as you can see only on my client I use local IP addresses to prevent my client for searching the internet for the non-existing dbserver.seinpost.nl address
Hope this helps,
Michiel

File size using JFileChooser

Hi,
I have a File[] array (with directories and files on it), and want to take to another array the size of files only. I don't want to use File.length, because in this way i take the size of directories too.
I tried to use this:
for(int i=0; i<array.length; i++)
File f = new File(path, array.toString());
Size[i]=f.length();
}//for
but i don't think is good to have a Size array with "zeros" (when it finds directories) and long values (when it finds files).
What do you propose me to do?
Would it be good to use JFileChooser and how?
Thanks,
TSolonel

What do you want to do with that array? Why not having a File[] array, so you have both length and isDirectory info. Sorting? Something else? JFileChooser seems irrelevant. But again, it's all up to what you are trying to do. Clarify
