How to read file in flex ?.

can anyone of you help me to know how to read a file in local
disk with flex.

You cannot! Flex is flash player based player meant to work
with browsers and browsers are not allowed to access the local
disks.
You can either read/write file on the server. or consider
using AIR.

[Urgent] How to read files from different directories?

I am new to Java Programming, I would like to know how to read files from directories other than the current one? (example as follows)
ProjectDirectory
|--MainDirectory
|--MainProgram.java
|--SupplementDirectory
|--SupplementProgram.java
|--Pictures
|--Image.gif
What should I write in the MainProgram.java so that I can use the supplementProgram.java from MainProgram and read the Image.gif file from the MainProgram.java?
Thanks

How to read file from remote machine

Hello,
Hi, i would like to know how to read text file from remote machine using java source code, any code ?
Thanks very much;
Best regards

On the server, perform the following steps:
Parse the request and determine the file to serve
Open a FileInputStream to the appropriate file
Obtain a reference to the Servlet OutputStream
Pipe the bytes from the file to the output stream
Flush and close the streamYou might want to call HttpServletResponse.setContentType("application/octet") to indicate to the browser that a file download will be occurring. Do so before getting the reference to the Servlet's OutputStream.

How to read file from server if I have a logical file path?

Hi guys,
I'm having a pretty "on the run" question,
My program is currently reading a file from server using "open dataset" with file path like this (just example)
/usr/interface/abc/bcd/testfile.dat
Now I got a requirement to make it more consistent to read files, instead of reading that physical file name, I should read the files from a specific folder using logical path.
So I go to T code "FILE" and created a logical path called ZABC_FILE_PATH, unix compatible, with physical path is (for example),
/usr/interface/<sysid>/<client>/<filename>
My question is, can I still use open dataset statement to read this? if yes, how do I do that? If no, there should be alternative way, please let me know what you think. Thanks,

Thanks all, I figured it out.
ONe thing is that typo double quote
The other thing is the importing part, I need the full file path.

How to read file header/open filein binary mode

i am using FileConnenction API to read from a file. how can i open a file in binary mode so that i can read file header. In other words i want to open a file in binary mode.

You can always try looking at the [Header Signatures|http://www.techpathways.com/uploads/headersig.txt]. But it would probably be easier to adjust your application so it doesn't have to guess.

How to read files....plzzz

Hi! All,
I have a problem in reading files using jfilechooser class.
when i select open menuitem from the file menu and reading it through
the file reader class it is giving nullpointer exception.
Also i tried by hardcoding filename in filereader class instead of using getSelectedfile().This time it is not giving null pointer exception but it is showing any stuff.
Here's the code i am using...
int returnVal = fc.showOpenDialog(openpanel);
if(returnVal == JFileChooser.APPROVE_OPTION){
file = fc.getSelectedFile();
               //This is where a real application would open the file.
if(fc == null)
     file = new File("D:\\karthik\\java\\");
     file = new File("D:\\karthik\\java\\kar.txt");
     fc.setCurrentDirectory(file);
BufferedReader infile = new BufferedReader(new FileReader(file));
     files.append(infile.readline()); //files is the textarea..

how come you do a fc.setCurrentDirectory(file);?
where exactly do you get the NullPointerException? what does your stacktrace say?

How to read file on demand (or) avoid polling in bpel 11g?

Hello -
Scenario - Receive two files(A & B) which should end up in two tables (Header, Lines)
BPEL process -
1) Receive acitivity - To Read file (A) via File adapter
2) Tranformed
3) Invoked the Db adapter to insert into "Header" table
4) Added another Receive activity - To Read file (B) via File adapter
5) Transformed
6) Invoked the Db adapter to insert into "Line" table
Issue - Step 4 gets fired as a SEPARATE instance (but no data in lines table) . At the end - I see the BPEL process which is waiting for File B. Even after I dropped File B - I dont see any records going into tables.
Is there a better way to design this process? Do I need to separate BPEL process to insert into Header & Line table? If so - how can I make this sequential process?
Appreciate detailed steps, if possible
Thanks
Babu

If its really a SyncRead Step 4 willl not run as a seperate process.
Step1: Initiates the process once the header file arrived
Step4: Will be invoked like a normal partnerlink.
Just make sure, you put the lines file before the header file in the directory.
If it doesnot resolve the problem, send your project to me helloprasanna at rediffmail.com . I'll have a look.

WebDynpro: How to read file content?

Hi,
My business scenario requires:
1, The file name is passed in through inbound plug parameter
2, I need to read the file content and then attach it to my CRM transaction
Please share with me how to read the file content.
The following approaches do not fit my scenario:
1, UI element: FileUpload
The reason is obvious: there is only file name parameter instead of any UI interface
2, Function Module: GUI_UPLOAD
The reason is that dump will happen in WebDynpro environment
Thanks & Best Regards,

and for the cert, if i have a biz relation with moto, they could give a "Develop Certification", or i must pay a third party to get a cert...
what a world~~~~~~~~~~~is unfair!!!

Do anybody know how to read file...

Hello,
I have a problem with reading config file. Do anybody know how to read config file from the same dir as class.
Now the situation is like:
filePath I hardcoded like:
fileName = "C:\\apache-tomcat-5.5.17\\webapps\\ROOT\\WEB-INF\\classes\\config.sales";
Is it possibility to read config file wich is used by java classes (in prj) from the same dir as classes are?
Thanks in advance.

If the file is in the class path you should be able to access it using the Class.getResourceAsStream method. It is the same concept as loading a properties file:

How to read file from server

Hi,
When i try to read file from server,the following message is displayed .
ORA-29532: Java call terminated by uncaught Java exception: java.security.AccessControlException: the Permission (java.io.FilePermission /tmp read) has not been granted to EWMTRACKTEST. The PL/SQL to grant this is dbms_java.grant_permission( 'EWMTRACKTEST', 'SYS:java.io.FilePermission', ' /tmp', 'read' )
ORA-06512: at "EWMTRACKTEST.GET_DIRLIST_EWM", line 1
ORA-06512: at line 1
thanks and regards
P Prakash

it seems obvious, user EWMTRACKTEST doesn`t have access to directory /tmp and the file under that.
try to give read permission and try again.
you could use command line like 'chmod' to grant permissions.
