Read bytes in file and print in clear text
Hi
I'm using hsql and use cached tables. This results in all data beeing stored in a binary file (Some of the data is stored in plain text though, but encrypted). The binary data starts and ends with ' (singlequote), the format is hexadecimal. How can I read this file and present all data in plain text, there is no need to decrypt the encrypted strings though.
Example of how the data is stored in the file:
W@ ` � M 43.6 Torticollis (nacksp��rr) h � X M 50 !Disksjukdom med halsryggssm��rtor � p � M 50.0 *Diskbr��ck i halskotpelaren med myelopati � p � 0 M 50.1 ,Diskbr��ck i halskotpelaren med radikulopati X h 0 M 50.2 !Annat diskbr��ck i halskotpelaren � p � � X M 50.3 'Annan diskdegeneration i halskotpelaren 0 `
I have some questions..
This results in
all data beeing stored in a binary file (Some of the
data is stored in plain text though, but encrypted).Encrypted text is binary data.
The binary data starts and ends with ' (singlequote),In your example, where is the '
the format is hexadecimal. In your example, I cannot see any hexidecimal formatted data.
Hexidecimal would look like: ABFEFDC8214634896FA8623EDB
How can I read this fileThe same way you would read any other file.
and present all data in plain text, there is no need
to decrypt the encrypted strings though.If you cannot decyrpt the string, it is not going to be in plain text, I fear.
Do you mean you want to see a binary file as hexidecimal?

Reading a image file and printing it by a Servlet
In a IMAGE TAG of HTML file i am calling servlets what will write a image to the browser.
<IMG SRC="http://localhost/WriteImage" width="50" height="100">
The Servlet WriteImage has to read a image from a location(it could be gif,jpeg,png or another format of images ) and it has to write to the above image tag.
Anyone can u help me out how i can do this...
I tried out with javax.imageio package but couldn't get it.
Thank Q
VijayYour WriteImage servlet needs to read the image file in from wherever it is (hard drive, database, whatever), then write it back out to the browser. To do that, first use the HTTPServletResponse object to send the appropriate headers, then call the getOutputStream() method to get an output stream to write the data to. This data will be sent to the browser which, if you've set the headers correctly, will display it as an image.
It's been a long time since I did this (we abandoned storing images in databases quite a long time ago), so I can't be more specific than that, but hopefully that'll be enough to get you going. If you run into any problems, reply and I'll see if I can help further. -
Issue : Read a text file and print the same
Hi, My requirement is to read a text file and print it the same way.
import java.io.BufferedReader;
import java.io.FileReader;
public class CatFile {
public static void main(String[] args) throws Exception
FileReader file = new FileReader("D:/Test/Allfiles.txt");
BufferedReader reader = new BufferedReader(file);
String text = "";
String line = reader.readLine();
while (line != null)
text += line;
line = reader.readLine();
System.out.println(text);
The text file i used contains
A
B
C
but my output is ABC.
What change should be made to print it the same way in the txt file ?Hi EJP,
I modified the code based on your suggestion and now its working as expected. Thanks
Modified code :
import java.io.BufferedReader;
import java.io.FileReader;
public class CatFile {
public static void main(String[] args) throws Exception
FileReader file = new FileReader("D:/Test/Allfiles.txt");
BufferedReader reader = new BufferedReader(file);
String text = "";
String line = reader.readLine();
while (line != null)
System.out.println(line);
line = reader.readLine();
text += line;

Reading in any file and converting to a byte array
Okay what I am trying to do is to write a program that will read in any file and convert it into a int array so that I can then manipulate the values of the int array and then re-write the file. Once I get the file into an int array I want to try and compress the data with my own algorithm as well as try to write my own encryption algorithm.
What I have been looking for is code samples that essentially read in the file as a byte array and then I have been trying to convert that byte array into an int array which I could then manipulate. So does anyone have any sample code that essentially takes a file and converts it into an int array and then converts it back into a byte array and write the file. I have found code that is close but I guess I am just too new to this. Any help would be appreciated.You can read a whole file into a byte array like this:File f = new File("somefile");
int size = (int) f.length();
byte[] contents = new byte[size];
DataInputStream in = new DataInputStream(
new BufferedInputStream(new FileInputStream(f)));
in.readFully(contents);
in.close();Note that you need to add in the proper exception handling code. You could also use RandomAccessFile instead of the DataInputStream.
Writing a byte array to a file is easier; just construct the FileOutputStream, call write on it with the byte array, and close the stream. -
How read a pdf file and change TableCell height after reading it using itext api

I am facing the same problem. Please help me out. I just want to read a PDF file as bytes from one location and write it as another pdf file in some other location with a diolog box prompting to open or save in the location where we want.
I executed the following code:
try{
File report =new File(location);
BufferedInputStream in=new BufferedInputStream(new FileInputStream(report));
response.setContentType("application/x-download");
response.setHeader("Content-Disposition", "attachment; filename=" + report.getName());
OutputStream outs = response.getOutputStream();
int readlen;
byte buffer[] = new byte[ 256 ];
while( (readlen = in.read( buffer )) != -1 )
outs.write( buffer, 0, readlen );
outs.flush();
outs.close();
in.close();
response.setStatus(HttpServletResponse.SC_OK);
} catch (FileNotFoundException fileNotFoundException) {
PrintWriter out= response.getWriter();
out.print("<center><Font color = 'RED'><b>"+PxDSLUtils.getApplicationProperty("label.error.CTM_E017")+"</b></Font></center>");
Though it prompts with open, save dialog box when i try to open directly or when i save it some where locally and then open it i am getting the following message " File is repaired ot damaged.Operation failed." Any idea about what can be done??? Its very urgent.Please suggest.
I am not convetin to string just reading and writng as bytes itself.
Thanks in advance,

Problem with file and printer sharing
I just installed a Linksys WRT54G to replace a D-Link wireless router and cannot reestablish my file and printer sharing since replacing the router. I had file and printer sharing working fine before installing the WRT54G. All of the computers are running either XP Pro or 2000 Pro. I have two printers attached to one of my computers that I was previously sharing with all of the other computers on our home network. One is attached via a parallel port, the other via a USB port.
Here's what I've tried so far without success.
1. The IP of the WRT54G is 192.168.1.1, and the IP's it assigns to my LAN computers begin 192.168.1.XXX. The old IP of the D-Link was 192.168.0.1 and its LAN IPs were 192.168.0.XXX, so I've gone into my firewall and changed the settings for the range of trusted computers to correspond to the WRT54G's IP addresses.
2. I've tried uninstalling the printers and reinstalling them, including reinitializing printer sharing.
3. When I try to use the Windows "Add printer" wizard to add a networked printer, it can see the computer that has the printers attached, but it does not see the printers.
4. I haven't fooled around with the file sharing settings, but they've all be lost too, so I suspect there is a common problem for both printer and file sharing.
Any suggestions would be most welcome. I don't know what would be different about the WRT54G that would cause this problem.Try this to Enable File and Printer Sharing...Turn Off the Router Firewall...Make sure the Windows Firewall is also Off...

File and Printer Sharing problem
Message Edited by bartman_60042 on 11-13-2007 05:47 AM
Oops...somehow submitted without any text.
My set-up: Linksys Cable Modem with Linksys Wireless Router. 2 Desktop Computers (Black and Grey) and 1 Laptop. Windows XP SP2 with all current upgrades on each.
While setting up File and Printer Sharing, I have the following:
1) The Black computer can file/printer share from both the Grey computer and Laptop.
2) The Grey computer can only file/printer share from the Laptop; not from the Black computer.
3) The Laptop can only file/printer share from the Grey computer; not from the Black computer.
All 3 computers were configured the same as far as I can tell. The only difference I notice is that the Black computer boots without the XP 'login' screen (no password required), could this be causing the problem? If this is the issue, how would I change the settings to 'login' to the Black computer? Any thing else which may be wrong? -

I didn't do a complete inspection of your code (because it's too much and unreadable as it is) and I don't know POI, but creating a new HSSFWorkbook for each input file sounds fishy to me ... try re-using the workbook and just creating a new sheet in each iteration. -
Reading A xml file and sending that XML Data as input to a Service
Hi All,
I have a requirement to read(I am using File adapter to read) a xml file and map the data in that xml to a service(schema) input variable.
Example of xml file that I have to read and the content of that xml file like below:
<StudentList>
<student>
<Name> ravi</Name>
<branch>EEE</branch>
<fathername> raghu</fathername>
</student>
<student>
<Name> raju</Name>
<branch>ECE</branch>
<fathername> ravi</fathername>
</student>
<StudentList>
I have to pass the data(ravi,EEE,raghu etc) to a service input varible. That invoked Service input variable(schema) contains the schema similar to above schema.
My flow is like below:
ReadFile file adapter -------------------> BPEL process -----> Target Service.I am using transform activity in BPEL process to map the data from xml file to Service.
I am using above xml file as sample in Native Data format(to create XSD schema file).
After I built the process,I checked file adapter polls the data and receive the file(I am getting View xml document in EM console flow).
But transform activity does not have anything and it is not mapping the data.I am getting blank data in the transform activity with only element names like below
---------------------------------------------------------------------------EM console Audit trail (I am giving this because u can clearly understand what is happening-----------------------------------------------------
-ReceiveFile
-some datedetails received file
View XML document (This xml contains data and structure like above xml )
- transformData:
<payload>
<InvokeService_inputvariable>
<part name="body">
<StudentList>
<student>
<name/>
<branch/>
<fathername/>
</student>
</StudentList>
</part>
</InvokeService_inputvariable>
'Why I am getting like this".Is there any problem with native data format configuration.?
Please help me out regarding this issue as I am running out my time.Hi syam,
Thank you very much for your replies so far so that I have some progrees in my task.
As you told I could have put default directory in composite.xml,but what happenes is the everyday new final subdirectory gets created in the 'soafolder' folder.What I mean is in the c:/soafolder/1234_xmlfiles folder, the '1234_xmlfiles' is not manually created one.It is created automatically by executing some jar.
Basically we can't know the sub folder name until it is created by jar with its own logic. whereas main folder is same(soafolder) ever.
I will give you example with our folder name so that it would be more convenient for us to understand.
1) yesterday's the folder structure : 'c:/soafolder/130731_LS' .The '130731_LS' folder is created automatically by executing some jar file(it has its own logic to control and create the subdirectories which is not in our control).
2) Today's folder structure : 'c:/soafolder/130804_LS. The folder is created automatically(everytime the number part(130731,130804).I think that number is indicating 2013 july 31 st like that.I have to enquire about this)is changing) at a particular time and xml files will be loaded in the folder.
Our challenge : It is not that we can put the default or further path in composite.xml and poll the file adapter.Not everytime we have to change the path in composite.xml.The process should know the folder path (I don't know whether it is possible or not.) and everyday and file adapter poll the files in that created subfolders.
I hope you can understand my requirement .Please help me out in this regard. -
File and printer sharing for Microsoft Networks on Windows server 2008
Hi Expert,
I found that the properties of File and printer sharing for Microsoft Networks service disabled after I install the windows server 2008 64bits. I tried to install that service via adding the file and printer sharing services in the properties of local area connection, but it doesn't contain any service in the popup box. Also, no such service file available in the disk when I tried to install the service from installation disk of windows server 2008 64bits. Is the file "sacsrv.dll" corresponding to the service name of file and printer sharing? I found it is in the directory of "Windows\system32". I have no idea about where is the problem? Do I miss some components? Please tell me what can I do for it? Thanks!
Best Wishes,Do any experts know the reason of this problem? Thanks!

Read in a file and convert into Binary
Hi there, i am new to java so plz give me a hand on this problem.
I am suppose to read in a file(with whole bunch of different records), and what i need to do is convert the file into binary.....how do i do that??
the original Q asked:
Create a java program that will read the products file and write the products data into a java binary file. Adhere to good data typing conventions. That means, if a column in the input file is of type integer, then the data in that column should also be written to the output file in integer format. Same thing for String...
Here is the code i have so far
import java.io.*;
class FileIO {
/* Main method */
public static void main(String[] args) throws IOException {
FileReader file1 = new FileReader("test.txt");
BufferedReader fileInput = new BufferedReader(file1);
FileWriter file2 = new FileWriter("test1.txt");
PrintWriter fileOutput = new PrintWriter(file2);
String text;
text = fileInput.readLine();
//toBinaryString(text); <---i think there is something to do with the tobinary string but i am not sure
System.out.println(text);
fileOutput.println(text);
// Close file
fileInput.close();
fileOutput.close();
E-mail me directly if it's possible, thanks a lot~!!!!!Maybe not the answer the teacher is looking for, but I'd be highly tempted to point out that the file, regardless of what's in it, is already binary. Even if it's a text file, what do you think the characters are defined as? Bytes.

E3000 file and printer sharing issues
Yes, there is at least one other thread on this but it looked a bit stale.
Last Friday I replaced my BEFSR41 router and WRT54G wireless access point (which had gone brick on me) with an E3000.The E3000 is configured as a DHCP server at 192.168.168.65 with a scope of 66-115. The only other non-default setting is that I opened up the custom port for my slingbox.
Prior to making the switch, I had several network shares on an XP desktop that I used frequently from my Vista laptop. Now, however, I can no longer even "see" any other computer from any of the computers on the network, much less access their shared folders. In other words, if I view the network from any of these machines, the only machine that shows up is the machine itself. Everything else (internet access, slingbox, a print server) is working just fine.
One of the suggestions in the other thread was to turn off Norton Internet Security, which is of course not a viable option. However I did check the settings, relaxed the network default to "Shared", and raised the XP desktop to "Full Trust". This had no effect.
I pinged the various computers, and was able to do so by their IP addresses, but not by their computer names (that worked with the old router). On a hunch, I tried creating a mapped drive, and that also worked when I used the IP address, but not when I used the computer name.
So - there's nothing wrong with the network configuration, or with how the shares are set up, and Norton isn't the problem. The only problem seems to be that names aren't being resolved, which could be affecting windows discovery, too. Did the BEFSR41 provide some local DNS functionality by default, and the E3000 doesn't? Is there an option I need to enable? If so, I can't find it. Perhaps I should explicitly add the E3000's internal IP address as a third nameserver??
A note on the "support" I tried to get before I turned to the forums: The "Chat agent" asked a bunch of questions, misunderstood my configuration and my problem, and once he finally did understand said "we don't support file and printer sharing". It took me several more questions to learn that he really meant that the Chat facility isn't the place for these questions - I had to call the 800 number. I did that, and after several minutes on hold, reached an agent. After going through everything again, and with the rep going on hold several times to "speak to his supervisor", he said it was "beyond his competence". I was eventually told I had to call another FEE-BASED service. I told him that was unacceptable.Ok, another update and possibly some clues.
I was curious why at one point, when all the computers were in Workgroup2, that "Workgroup" still showed up in Explorer under the list of networks, but only on the two XP machines. Netscan showed this group association as well, which I then realized was the E3000 itself, in its role as a [I]potential[/I] NAS server. However there was no storage device attached.
Could this in itself cause the access error? If so, should users be advised that if they don't plan to host any storage, that they should to go to the E3000 Storage Administration page and change the workgroup name to something other than their actual workgroup name?
In my case, I changed it to "Workgroupx", though perphaps something like "StorageGroup" would be more meaningful, especially if the Workgroup computers could still access any storage I might install in the future.
Anyway, I repeated my original approach (after the above change and a router reboot), and at least got my original Workgroup reestablished to the point where the XP machines not longer get access errors, and most machines can access the shares on the XP desktop. The steps I used on each machine were:
remove any shares I had set up on any folders
uninstalled the File and Printer Sharing service
Accessed Computer Name properties page to change the workgroup name
Shut Down
After all 4 were done, I reversed the process:
Started computer (now coming up in new Workgroup)
Reinstalled File and Printer Sharing service
Checked visibility
At this point, the XP machines could see each other, and the Win7 and Vista machines could see each other, but initially these two cliques wouldn't interact.
Next I re-added the shared folders on the XP desktop, and the XP netbook could see and access them. After about an hour, the Win7 machine joined this clique, and could also access the shares. But six hours later, the Vista machine is still clueless. Netscan shows everything of course, and I used it to set up a mapped drive on the Vista machine to one of the shared folders.
Other possibly relevant facts:
The was all working fine with the BEFRS41/WAP54G combo
I can ping all machines by IP address, but not by name
On the Vista machine I can set up mapped drives to the XP's shared folders, but again, only by IP address.
At one point I removed NWLink from the XP desktop. Now, nbtstat -r only shows the printserver's name being resolved.
The two XP machines, being SP3, lack the LLTD responder.
So,
Is it possible the NetBIOS in NWLink was providing some kind of name caching? If so, should I reinstall the protocol driver (I don't think it is available on Win7)?
Should I request and apply the KB922120 hotfix to get LLTD onto the XP machines?
Perhaps in the morning, "by name" access will have returned, as it did on my first go-round. Needless to say this has been a real pain, what with all the reboots required. At least now I remember to hit F8 so I can select Safe Mode with Networking... -
1.is it possible to read a .xls file and load it into an oracle table
1.is it possible to read a .xls file and load it into an oracle table, using oracle database or oracle forms i.e. either utl_file, or text_io, or any other oracle tool.
As far as I know we need a csv file or a txt ( tab delimited) file ?
2.Are there any windows tools for the sameHi,
If you want to use the DDE package to read the XLS file then yes, you will neeed to know the number of rows and columns in the input file.
i.e. How will you know :
1) How many columns are there in the input file.
If I have a XLS file with the following data :
R1C1 R1C2 R1C3 R1C4 R1C5 R1C6 R1C7
xxx xx x
Where R represents row and C represents column, then how will you know the each row has 7 columns. If you know the answer upfront, then it's not a issue.
Using the DDE apprach, you will have to specify the RowNum and the ColumnNo of each idividual cells to read/write data from xls sheet.
Look at the syntax in my ealier post.
using the other approch (i.e. comma delimited text file - CSV file) , you need not know the number of columns as you can loop thru the input record till the last column is read.
All you have to do is to look for the 'n' occurances of the field delimiter say ',', do a substr from the current position to the point where the ',' was found.
This process is to be repeated in a loop till all columns are read.
The TEXT_IO package can trap for EOF (End Of File).
Hope I made myself clear.

How can I get to read a large file and not break it up into bits
Hi,
How do I read a large file and not get the file cut into bits so each has its own beginning and ending.
like
1.aaa
2.aaa
3.aaa
4....
10.bbb
11.bbb
12.bbb
13.bbb
if the file was read on the line 11 and I wanted to read at 3 and then read again at 10.
how do I specify the byte in the file of the large file since the read function has a read(byteb[],index,bytes to read);
And it will only index in the array of bytes itself.
Thanks

I would also like to hate on the name 'RandomAccessFile' almost always, there's nothing 'random' about the access. I tend to think of the tens of thousands of databases users were found to have created in local drives in one previous employer's audit. Where's the company's mission-critical software? It's in some random Access file.
Couldn't someone have come up with a better name, like NonlinearAccessFile? I guess the same goes for RAM to...Non-linear would imply access times other than O(N), but typically not constant, whereas RAM is nominally O(1), except it is highly optimised for consecutive access, as are spinning disk files, except RAM is fast in either direction.
[one of these things is not like the other|http://www.tbray.org/ongoing/When/200x/2008/11/20/2008-Disk-Performance#p-11] silicon disks are much better at random access than rust disks and [Machine architecture|http://video.google.com/videoplay?docid=-4714369049736584770] at about 1:40 - RAM is much worse at random access than sequential. -
Script to install and enable file and printer sharing windows 7
Hello
I posted this question on the Microsoft Partner Windows 7 forum and the support person told me that I should post it here.
I have a Customer that was running Novell. We will migrate them to Active Directory.
The question I have is. they did remove the file and printer sharing service on their Windows 7 workstations.
Is is possible to have a command line or a script to install and enable the file and printer sharing for Microsoft Network?
We need this enable in order to install the SCCM client remotely
Greetings
Gaetan LabrecqueHow are you going to connect to the workstations?
File and print sharing are not needed for Group Policy to work. GP can be used to re-enable file and Print Sharing.
You will also need to start by joining the machines to the domain. That will be very difficult unless all have PowerShell and are configured for WinRM.
This can be somewhat accomplished by using VBScript remotely but will require a very sophisticated admin to set up and debug in your environment. I recommend hiring a consultant who has experience in conversions or is a master VBScripter in a domain.
There is no easy answer. It is not about File Sharing.
Here is how to add roles and features with PowerShell:
