Problems reading files. Updated
Hello
This is a update for my old topic, my real problem was read the file and then pass to a String variable, I try to read the file in binary mode, then the buffer with data pass to a String with the constructor String a = new String( bytearray, 0. bytearray.length()); then the problem occurs, the non printable characters appear like ?, I don't want this behavior
Can you help me on this?
Thanks
How about something like this?BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(new File("my file name"))));
String s = br.readLine();Mark

Yes, but that would not cause the "build failed" message.
right I missed that part. Looks like two problems then.

Problem reading file after using webutil_file_transfer.as_to_client
Hi all,
The Forms webapplication I'm working on has to talk with a cardreading-application on the client-PC. The communication is carried out by exchanging small files. Reading from the client by Forms on the AS goes well (using client_text_io from webutil). The problem arises when the application has to respond back with a file. The file is made on the AS and then transfered from the AS to the client using webutil_file_transfer.as_to_client. This file can not be read by the cardreading application when the AS is on Linux. Our developement AS server is on a Windows 2000 box and then the communication doesn't show this problem.
If I open the file from the AS on Linux , I can see that there is only 1 long line. The Windows version of the file contains 2 lines (as it should be). It seems that before/during/after the transfer some special characters like carriage return and tab are causing the problem.
Looking in web_file_transfer.as_to_client I see that the procedure reads lines from a temporary file into a buffer. The lines are separated by a CHR(10). Could the transfer from Linux to Windows(DOS) cause a problem with these characters ?
Has anyone experienced this problem ? If someone has a clue this would be very welcome.
We work with :
- Forms and AS 10.1.2.0.2
- Webutil 1.0.6
- Development OS: Windows 2000 (Service Pack 4)
- Production OS: Red Hat Enterprise Linux AS release 3 (Taroon Update 3)
- Client-PC OS: Windows 2000 (Service Pack 4)
Thanx,
EnricoWithout going into a long winded answer, the only thing I can really offer is to say this... If you feel as though your code has been correctly written and you simply cannot identify any other possible solution, add SYNCHRONIZE. In short, its execution acts similar to a reset or refresh button.
Another common place where SYNCHRONIZE has been helpful is when calling RUN_REPORT_OBJECT. For example, if you use the code we offer in the Forms/Reports Integration document you will find that it works very well - most of the time. However, sometimes it fails for what seems to be unexplainable reasons. If you message out the values being assigned you will see that some variable values are not being set even though the code execution has already passed the point where a value should have been assigned. Adding the SYNCHRONIZE just after the point where the value should have been assigned forces the assignment before executing the next line of code. For example,
v_rep := RUN_REPORT_OBJECT(repid);
rep_status := report_object_status(v_rep);
In the above code, a request for a report is made followed by a check of its status. At this point you would expect that the status would be something like one of the following:
'RUNNING', 'OPENING_REPORT', 'ENQUEUED'
However, we have seen instances where the value assigned to the variable would actually be NULL, which of course will make the rest of the code likely fail. By adding SYNCHRONIZE the problem is correctable.
v_rep := RUN_REPORT_OBJECT(repid);
rep_status := report_object_status(v_rep);
SYNCHRONIZE;
It is important to understand, however that using SYNCHRONIZE comes at a price. Each time it is executed a network round-trip occurs which will give the application the appearance of degraded performance. So use this built-in only when you know you must. -
Hello,
the following code reads a file into a byte stream:
URL url = new URL("some filename under the codebase");
InputStream inStream = url.openStream();
int inBytes = inStream.available();
byte inBuf[] = new byte[inBytes];
int bytesRead = inStream.read(inBuf, 0, inBytes);
inStream.close();
this code used to work, but after changing virtual machine it doesn't. the problem is that only part of the file is being read. I'm sure there is better code for this situation - any ideas?
thanks,
OriProblem is the use of "inStream.available();" available() is not giving you the actual size of the file it gives you the number of bytes that you can read without blocking that means the number of bytes that has be downloaded to the client.
here is a better solution:
ByteArrayOutputStream()
URL url = new URL("some filename under the codebase");
InputStream inStream = url.openStream();
ByteArrayOutputStream tempBuffer = new ByteArrayOutputStream();
byte b[] = new byte[1024];
int count=0;
while ((count = inStream.read(b))!=-1){
tempBuffer.write(b,0,count);
inStream.close();
byte inBuf[] = tempBuffer.toByteArray();By the way what are the data in the file that you are reading If it is it text or something else
If it is text you can directly use DataInputStream to read line by line -
Problem reading file in tomcat
Hai I have a problem,
i am working on project for which we have created a directory in the defaultroot directory of the apache tomcat server.I have written a java program to read a file.Now the problem is coming as to where to put the file and if i want to place that file in the created directory under defaultroot,what path should i give to access this file..
for eg: i want to put the file test.txt under the folder /defaultroot/test/test.txt then what path should i give in my java program. if i use ../test/test.txt then it says path is not present since using ../ is going into the tomcat directory. i can explicitly give ../defaultroot/test/test.txt but i dont want to hardcode defaultroot. Any suggestions?
thanksU can considering having the path in a property file and using it in the problem

Hi,
I'm, trying to read a file that has a format similar to a sorce code.
This is the content of the file:
BEGIN
CLOCK_LOOP : LOOP
END LOOP CLOCK_LOOP;
END PROCESS;
I'm using the following code:
while((line = br.readLine()) != null) {
String result = "";
String delimiters = "+-*/(),. ";
StringTokenizer st = new StringTokenizer(line, delimiters, true);
while (st.hasMoreTokens()) {
String w = st.nextToken();
if (w.equals("BEGIN")) {
System.out.println(line);
This works perfectly. But I need to read the lines starting from CLOCK, so when I change the word BEGIN to CLOCK i get this error:
Error de E/S java.net.SocketException: Connection reset
How can I solve this?I did what you told me, so this is what I'm trying now:
while((line = br.readLine()) != null) {
String result = "";
String delimiters = "+-*/(),. ";
StringTokenizer st = new StringTokenizer(line, delimiters, true);
while (st.hasMoreTokens()) {
String w = st.nextToken();
if (w.equals("BEGIN")) {
System.out.println(line);
break;
while((line = br.readLine()) != null) {
String result = "";
String delimiters = "+-*/(),. ";
StringTokenizer st = new StringTokenizer(line, delimiters, true);

It only prints BEGIN -

Is anyone having the same type of problems I'm having with Lion. I have a new MacBook Pro, received 7 weeks ago, preinstalled with Leopard 10.6.7. I didn't migrate anything from my old iMac, wanted a clean install from the Apple Store. While there, I asked for the upgrade to Lion 10.7, however their system was down.
I installed it myself, wirelessly about a week later, and Apple emailed me a receipt. Now, I've had to call support directly last week when I lost Mail, Address Book, was unable to open Preview or iTunes, among other problems. Seemed fixed after a session that baffled even the store tech. Now I am unable to download or install the recent Mac updates for Lion, from the App Store, could not install Adobe Reader, etc. Messages range from 'A network error has occured - Check your Internet connection and try again' to 'The Installer is damaged and cannot open the package. There may be a problem with file ownership or permissions.' All fail and I'll probably have to call Apple again. I am frustrated beyond words. Logs 'Install's runner tool is not properly configured as a setuid tool', domain errors, 'attempt to write a readonly database, and on and on. I have barely done a thing on this computer except search online for help with these problems. Safari gives me a 'You are not connected to the internet' too often. Diagnostics disagrees. I do see wi-fi problems in the forum. Disk and permissions were fine at the beginning of the earlier problems, checked first by support tech. I'm not sure if support tech even knew. I was just happy they were fixed. Anyone have these download and/or install problems after a 'clean bill of health' so to speak, only a week ago?Let's try the following user tip with that one:

Problems reading RAW format after update 6.03
I have problems reading RAW format images into Iphoto 9.6 after update 6.03 or maybe earlier updates (have not imported for a few months). The images show up like half, black or partly distorted. I use a Canon 5D mk2 camera. The images looks okey when read into a PC so I don´t think it is the camera or cables. It has been working very good before! I use a Powerbook pro 13 late 2011 with Yosemite 10.10.1.
Try downgrading back to 6.02 by following the directions in this post by léonie:

Re: Digital Camera Raw Compatibility 6.02 - Nikon D800
in response to ceylin.e
[DocumentBodyStart:3bf5afd7-94e9-4fb4-acfa-7aa13198efec]
Make a backup of your system and try to downgrade the RAW support to version 6.01
To downgrade the RAW Support to the last version from before the last update try this:
To reinstall the 'RAW Compatibility Update' it is necessary to uninstall the currently installed raw support. Otherwise the installer will rightfully say, that you already have the latest version installed.
If your tests are showing that the problem happens also in a different user account, try this:
The RAW support files are installed in the System Library in the folder "/System/Library/CoreServices" Folder:
To open this folder, use the Finder's "Go" menu. Click the smiling Finder icon in the Dock to bring the Finder forward.
Then type the keyboard shortcut ⇧⌘G (for "Finder > Go > Go to folder") and copy and paste "/System/Library/CoreServices" into the text field. Click the "Go" button.
In the Finder window that will open, delete both the files "RawCamera.bundle" and "RawCameraSupport.bundle". You will have to enter your Administrator password. (don't empty the Trash, so you can put the files back, if need be)
Download the current RAW support update from Apple's Support Site:
Digital Camera RAW Compatibility 6.01 http://support.apple.com/kb/DL1777?viewlocale=en_US&locale=en_US
In the Downloads folder you will find the disk image with the installer. Double click it to open and run and the installer.
Then restart your Mac. -

The file that you downloaded is a self-contained running application that installs the update on your computer. After you download that file, you need to double-click on it and follow the prompts to install it. After it has completed you will have Lightroom 4.4 installed and it will be ready to run. If you are on a Windows computer, the installation will replace your 4.1 installation. If you are on a Mac then you will have both versions installed and you will have to be sure you start the right one.
