Scanned text files

Once agian.... every question I ask is NEVER answered. I can't believe that I am the only person in the world that has this simple problem.
I want to add a simple scan to my iMovie project. No matter what I do or what file I import, the image is blurred or pixelated???
I need to add a "form", a image of a page to my iMovie. How the heck do you do it??

If it is text and not a photographic image you might have better luck scaning as a png
PNG format is a lossless compression file format, which makes it a common choice for use on the Web. PNG is a good choice for storing line drawings, text, and iconic graphics at a small file size.
JPG format is a lossy compressed file format. This makes it useful for storing photographs at a smaller size than a BMP. JPG is a common choice for use on the Web because it is compressed. For storing line drawings, text, and iconic graphics at a smaller file size, GIF or PNG are better choices because they are lossless.

Trying to Scan in a List of Names Using a Delimiter from a Text File

Hello everyone,
I tried posting this question onto [Codecall Forums|http://forum.codecall.net/java-help/16064-trying-scan-list-names-using-delimiter-text-file.html] for an answer, but nobody really helped to solve this problem, so I'm reposting it here.
I'm trying to solve this problem on the Euler Project for practice. For the first part of the problem, I am supposed to scan in names in the following format: "name1","name2","name3". To solve this, I wrote the following code:
import java.io.*;
import java.util.*;
public class AlphabeticalSort
     public static void main(String args[]) throws IOException
          //import the file
          Scanner input = new Scanner(new File("names.txt"));
          input.useDelimiter("[\",]");
          System.out.println(input.delimiter());
          //scan it for the length of the array
          int n = 0;
          while (input.hasNext())
               input.next();
               n++;
          System.out.println(n);
          //import the names into the array
          Scanner input2 = new Scanner(new File("names.txt"));
          input2.useDelimiter("[\",]");
          String[] names = new String[n];
          for (int i=0; i<n; i++)
               names[i] = input2.next();
               System.out.println(names);
}However, when I tested this with a file containing "BOB","STEVE","MARK", n equaled 7 and my output was the names each separated by two empty lines. There are other methods I can use to solve this problem, but I would really like to know why my delimiters are not working so I can use them in the future.
Thanks,

Take a look at [Quantifiers in Java regex|http://java.sun.com/docs/books/tutorial/essential/regex/quant.html].
I believe "[\",]+"{code} will get you the results you need.

How can users who have Acrobat Reader only save scanned pdf files so that the text on them is searchable using ctrl-F? I just use the recognize text with ocr feature in the full version of Acrobat and this seem to do the trick. Reader doesn't work!

Our users have scanned pdf files they want to be able to search using ctrl-f. I got them to be searchable by doing a recognize text using ocr with Acrobat Professional vesion 8. They want to know if they can make the files searchable with Acrobat Reader only or if they need the full Acrobat Professional software to make the files searchable.
Thanks for the help!!
Ken K. - 2191

To clarify a bit they need to have Adobe Acrobat, not Adobe Reader. Reader has not been associated with the Acrobat name for 3 or more versions. The process you are asking about is a creation process - the purpose of Acrobat - and NOT a reading feature.

Scanning characters in a text file

Hello, firstly I am trying to get the program to work, then I will use different methods (program description shown in code).
I have not done Java for a while therefore I do not know if i am on the right track or not - please say. Basicly I have the characters in an array, but when I display them its looks like 160, 160, 12, 13, etc etc i.e. their is a separate number for each character.
What I need to know is how to I get this number back to a character?
Thank you anyone
import java.io.*;
* Write an application which scans through a text file, and counts
* (and displays) the occurrences of a particular character (supplied
* by the user) on each line of the file. Use a method to count the
* occurrences on one line. The specification of the method should be:
* private int countCharacters(String line, char c)
* The method returns the number of �c� character in the line.
public class TextfileScan2
     public static void main(String[] args)throws Exception
          byte[] byteArray = new byte[100];
          FileInputStream in = new FileInputStream("File.txt");
          int byteRead;
          int index = 0;
          while ((byteRead = in.read()) != -1)
               byteArray[index] = (byte)byteRead;
               index++;
          in.close();
          for(int i = 0; i < byteArray.length; i++)
               System.out.println(byteArray);

No need to get quite so uptight. Anyway I think I am making progress although what I have does not compile as it says I need to add curly braces to lines 28 and 44.
Can someone please tell me why I get this error. Maybe the name of the methods - have tried changing but no luck.
cheers

Envy 4500 won't scan text to produce a searchable PDF file

I used to have a Photosmart 4400 C printer that would let me scan to produce searchable PDF files, i.e. I could select letters or words using a text selection tool in my PDF reader. Today I Just purchased a ENVY 4500 e- All-in-One-Series. It will only scan text to give me a graphic PDF file that is not searchable. I updated to the latest driver EN4500_198.exe but that doesn't help. Does anyone have a solution?

Hi, No, the Envy 4500 does not have any OCR software by default, you have to pay for that software and believe this or not, the software is more expensive than the printer itself. You can buy the software or you can try to use few free software around: http://www.techsupportalert.com/best-free-ocr-software.htm Regards,

Using get -childitem to scan different drives but append one text file.

Folks,
I need some help, I wrote the below to scan for certain files types on client machines but I cant get the script to scan anything other than the C$. Apologies I am kind of new to scripting and PS. The script is kicked off using a batch file that makes the
CR directory on the clients. I think the problem stems from the $disk variable or the way I have used foreach or the loop - any help would be appreciated
Set-Location c:\
$s = new-object -comObject SAPI.SPVoice
$s.speak("Scan in progress")
write-host "Scanning for files"
$Extension = @("*.zip","*.rar","*.ppt","*.pdf")
$Path = "$env:userprofile\Desktop"
$disks = "c$","D$"
foreach ($disks in $disks)
{get-childitem -force -include $Extension -recurs -EA SilentlyContinue >$path\files.txt}
$s.speak("Scan completed")
Write-Host "Scan complete, files.txt created on your desktop - press any key to exit..."
$x = $Host.UI.RawUI.ReadKey("NoEcho,IncludeKeyUp")
Remove-Item c:\cr -recurse -EA SilentlyContinue
exit

Then there is "$x = $Host.UI.RawUI.ReadKey("NoEcho,IncludeKeyUp")" , What are you trying to do?
It looks like that is a pause after the code has completed to give the user time to read the message prior to exiting.
@V Sharma - As gaff-jakobs has mentioned, there are some parts of your code that need looked at. Please take a look at what he has advised and make the necessary changes. If you want to append data (doing a > does not append), I would look at using Out-File
-Append -FilePath <filename> to accomplish this.
Usually, outputting to a text file limits what you can do with the output once it goes to a text file. I would look at using something such as Export-Csv -Append -Path instead (assuming you are running PowerShell V3). But if saving to a text file is part
of your requirement, then just be sure to use the first method I mentioned.

Want to scan to text file on hp oj8600, software indicates only pdf or jpg file creation

want to scan to text file on hp oj8600, software indicates can do. However printer system software only allows pdf or jpg file type creation.

Hello @Richf95,
Welcome to the HP forums.
I understand that you are trying to save scans as a text file.
I would like to help.
PDF has become the standard file type used when scanning/saving a document.
Most printers will not have text as a default option.
Try the following:
Open the HP scan utility
In the lower left hand corner select 'Create New Shortcut...'
Name your new short cut. I went with Text.
In the next window select the file tab.
In the drop down menu, select Text.
This should create a shortcut that will allow you to save scans as a .txt file.

How to scan/ read a text file, pick up only lines you wanted.

I'm new to Labview, I trying to wire a VI which can read a text file
example below:
Example: My Text File:
1 abcd
2 efgh
8 aaaa
1 uuuu
and pick out only any line which start with number 1 (i.e 1 abcd)
then output these 2 lines out to a a new text file?
Thanks,
Palmtree

Hi,
How do you creat your text files? Depending on the programm, there is added characters in the beginning and at the and of the file. So here you will find a VI to creat "raw" text files.
To debug your VIs, use the probs and breakpoints, so you can solve the problem by your self or give an more accurate description of it.
There is also the VI that read a integer and two strings (%d %s %s)

How to retrieve specific data from a text file

Hi, everyone
For my project it is required that a parameter file is read at the beginning, in order for certain variables to be initialized with specific values that change with the user.
At the moment, the way it is done is the following: The values at a specified sequence in a text file are read and saved in an array and the elements of the array are retrieved according to their index.
The problem with this implementation is, that if for some reason the format of the file changes, e.g. we want to use a parameter file from a previous version of the program that has the values for the same variables but in a different order, the only way to have the right values for the parameters is to change everything accordingly, which is really time wasting.
Could someone suggest a different implementation that would make the reading of the different values independent from their order in the file, e.g. by scanning the file for specific strings and reading the value after the string?
Thank you very much.
P.S. I have attached a screenshot of the routine I am using now.
Solved!

Hi panagiov,
Find attached Folders.
Method 1: in this you can search for each variable separately. You can use "Config file vis" to get all keys(Variables) at once and then you can use for loop to get their values. Or you can access individual values as shown in this code.
Method 2: here you will get all data at once. You will get Variable and Data (2D array) You need to search variables as and when required.
I hope you will understand these methods.
Best of luck

How to parse data from a text file with no convenient delimiters?

I need to read data from a text file. This file contains one line of data with the repeating pattern "time 00 ADVar2: ___ Height: ____ time 01 ADVar2: ___ Height: ___ ..." I need LabView to parse out the "time" and "height" values, build an array with the values, and graph the correlation on an X&Y plot. Does Labview have an automated way to read to the input data file and parse out the correct values, even without convenient delimiters? Thank you.

You actually do have a convenient delimiter: "time". Thus, you can make an array using that as the delimiter. Only caveat is that the first array element will be empty. Then you can conveniently use the Scan From String function in a for-loop. Something like this:

Find words within a text file

Hey all.
I am playing around with the idea of finding a line of text within a text file, by using scanner and some next methods.
The way I am trying to get it to work is that one enters a string and the program then finds all the lines of text containing that
user-entered string and then prints them.
The text file in question contains names of University papers and their room numbers, quantity of students etc.
Example:
IBUS212     EALT006     1am     72     AL     LI
BMSC241     MCLT102     2     pm     8     AL     COOREY
My problem annoyingly enough seems to be that I can't think how one could compare the string entered to the lines of text being
scanned in the text file.
My latest go involved what you see in the code, scanning the examdata.txt file for a user-entered course number, using course.next();
by going with the example above it would be IBUS212. The task was to then to find all of the lines containing that number and print them out using
println (what I have tried with id and line) as well as the rest of that line eg: EALT006     1am     72     AL     LI .
   public void printCourse()
    try
        String details, input, id, line;
        int count;
        Scanner user = new Scanner(System.in);
        System.out.println();
        System.out.println();
        System.out.println("Please enter your course ID: ");
        input = user.nextLine();
        Scanner course = new Scanner(new File("examdata.txt"));
        course.next();
        course.nextLine();
        id = course.next();
        line = course.nextLine();
        if(input.equals(id))
            System.out.println("Your course times are: " + id + "and" + line);
        else
          System.out.println("Your course does not exist.");
        catch(IOException e)
            System.out.print("File failure");
}Any advice/help/troubleshooting would be greatly appreciated.

You'll want [to loop while|http://java.sun.com/docs/books/tutorial/java/nutsandbolts/while.html] the course Scanner has a next line and then print the line if it contains the entered text.
For useful methods you can check the Javadoc of String and Scanner (use your browser search on keywords like 'next' or 'contains' to find them).

Importing text file into 2D char array

Hey folks. I've aged a few years trying to figure this project out. Im trying to make a crossword puzzle and am having problems importing the answer letters into a 2D array of 15*15. The text file would look something like this:
LAPSE TAP RAH
AVAIL OLE ODE
BARGE PARADOX
etc
I have JTextFields that the user will answer and a button the user can press to see if the answers are right by comparing the 2D array answer with what the user inputted.-the user input would be scanned and put into a 2D array also.
How should i go about inserting each letter into an array? The spaces i would later need to make code to grey out the text field. This is what i have so far. Forgive me if its sloppy.
     class gridPanel extends JPanel
          //----Setting Grid variables
          private static final int ROWS = 15;
          private static final int COLS = 15;
          String[] letters = { "A", "B", "C", "D", "E" };// To test entering strings into array
           gridPanel()
             this.setBackground(Color.BLUE);
             //.......Making my JTextField grid for user input
             JTextField[][] grid = new JTextField[ROWS][COLS];
             for(int ROWS = 0; ROWS<grid.length; ROWS++)
                 for(int COLS = 0; COLS<grid.length; COLS++)
                     grid[ROWS][COLS] = new JTextField(1);
                     add(grid[ROWS][COLS]);
                 //grid[ROWS][COLS].setText("" + letters[0]);
             String an = null;
             StringTokenizer tokenizer = null;
             Character[][] answer = new Character[ROWS][COLS];
          try{
             BufferedReader bufAns = new BufferedReader( new FileReader("C:\\xwordanswers.txt"));
             for (int rowCurrent = 0; rowCurrent < ROWS; rowCurrent++)
          an = bufAns.readLine();
          tokenizer = new StringTokenizer(an);
          for (int colCurrent = 0; colCurrent < COLS; colCurrent++) {
          char currentValue = tokenizer.nextToken().charAt(0);//Needs to be changed to reflect each letter
                    answer[rowCurrent][colCurrent] = currentValue;
                System.out.println(currentValue);
          }catch (IOException ioex)
                    System.err.println(ioex);
                    System.exit(1);
        }//xword graphics end
      This obviously prints the first char of each word, it also gives me an "Exception in thread "main" java.util.NoSuchElementException" error for some reason.
Any help is greatly appreciated.
John

If the file format is stored as follows:
APPLE
L A
PARSE
N E
PEAR then we can parse this into a 2D char array:
char[][] readMap(String fileName) {
    char[][] ret = new char[ROWS][COLS];
    FileInputStream FIS = new FIleInputStream(fileName);
    int i, j;
    for(i = 0; i < ROWS; i++)
        for(j = 0; j < COLS; j++)
            ret[i][j] = FIS.read();
    FIS.close();
    return ret;
}Then you can use the resulting 2D char array in your answer checking mechanism.
Hope this helps~

Skipping Blank Lines in text File

I am working on an assignment in which i have to read from a text file and store the strings individually. The problem i have is that the text file has blank line between each set of strings. So i figured to use "fin.nextLine();" to skip that blank line and continue with storing the values. but i get
"Exception in thread "main" java.util.NoSuchElementException: No line found
     at java.util.Scanner.nextLine(Unknown Source)
     at processmsg.ProcessMessages.choice1(ProcessMessages.java:68)
     at processmsg.ProcessMessages.main(ProcessMessages.java:25)"
which is where the fin.nexLine() is at. How can i just skip that blank line?
System.out.println("Please enter the file location");
          Scanner stdin = new Scanner(System.in);
          String fileName = stdin.nextLine();
          // read the information from the file
          try {
               Scanner fin = new Scanner(new File(fileName));
               String tSendName = fin.nextLine();
               while(tSendName != null)
                    String tRecieveName = fin.nextLine();
                    String tPhoneNumber = fin.nextLine();
                    String tDate = fin.nextLine();

                    fin.nextLine();
                    tSendName = fin.nextLine();

don't know if you want the whole code, the whole code is kind of large and spread out over 3 different classes. and yes the text file is standard
sender
reciever
phone number
date
time
status
message
sender
reciever
phone number
date
time
status
message
sender
reciever
phone number

Implementing an Anti-Virus File Scan in JEE Applications
By Vlad Kofman
Go to page: 1 2 3 Next
This article will discuss one of the ways to implement antivirus file scanning in Java, particular in the JEE applications. Viruses, Trojan Horses, and different malware and spyware are a real problem for current computer environments, and especially for the Windows operating system. If you are designing any application in Java that has a requirement to be able to upload external files, you have a potential security risk. By uploading, I mean any way to get the external file inside of the corporate firewall be it via HTTP protocol or any other means. It is quite common to have this type of requirement in an enterprise application and with Java being one of the most popular web development platforms, it is unfortunate that this type of gaping security risk is quite often overlooked.
Java's Development Kit (JDK) does not have any means to do the antivirus scan right out of the box. This is primarily because Java is a programming language, and does not have any virus scanning packages. Furthermore, anti-virus software is not Sun's area of expertise or business model. Developing this type of software (or Java package), and more importantly maintaining it, would be a huge task for Sun. Mainly because viruses are constantly evolving and keeping virus definitions up-to-date is a daunting task. Large companies such as McAffee, Symantec, or Zone Labs develop virus detecting and combating products and spend a lot of resources to maintain them.
Application Environment
To implement a virus file scan in Java, a third-party package needs to be used. For the purposes of this article, I will use Symantec Scan Engine (SSE) package, which comes with Java APIs. This package is an application that serves as a TCP/IP server and has a programming interface and enables Java applications to incorporate support for content scanning technologies. For this article, I used Symantec Scan Engine 5.1, which is available as a Unix or Windows install.
If you are using an anti-virus package from the different vendor, you will need to investigate what kind of APIs are available; however, the general approach should be similar. Also, note that my implementation can be used with JEE technology and any modern MVC framework such as Struts or Spring.
The architecture is as follows: A server machine needs to have SSE running at all times. This can be the same machine that hosts your Application Server, but in an enterprise environment this should be a different machine. The Default Port needs to be open through the firewall to allow communication with the scan engine. All JEE applications that need to do file scanning can talk to the SSE server machine through a default port. Also, multiple applications running on different application servers can re-use the same scanning server. For more information, you should refer to the Symantec Scan Engine (SSE) Installation Guide, available on the Symantec web site.
When an external file that needs to be scanned is sent to the SSE via its programming interface (Java APIs using the default port), before any other operation on the file is performed, the SSE returns a result code. For instance, a file is uploaded by an external user into the web email type application as an attachment; then, the SSE API is invoked by the application and the return code of pass or fail determines the outcome of the upload and whether that email can actually be sent. If you have an account on Yahoo mail, you probably have seen that Yahoo is using Norton Antivirus to scan all attachments, although no Java.

Figure 1: Screen shot from Yahoo
For details on the Scan Engine Server Installationm please see the Symantec Scan Engine (SSE) Implementation Guide from Symantec.
Here are some key things to remember about SSE:
•     Java 2 SE Runtime (JRE) 5.0 Update 6.0 or later must be installed on the server before the SSE installation is done.
•     After installation, verify that the Symantec Scan Engine daemon is running. At the Unix command prompt (if it's a Unix install), type the following command:
ps –ea | grep sym.
A list of processes similar to the following should appear:
o     5358 ? 0:00 symscan
o     5359 ? 0:00 symscan
If nothing is displayed the SSE process did not start.
If the SSE process did not start, type the following command to restart SSE:
/etc/init.d/symscan restart
•     Keeping the virus definition up to date is the most important task and if new updates are not installed, the whole scan becomes ineffective. Symantec automatically downloads the most current file definitions through LiveUpdate. Please make sure that firewall rules are in place to allow the host server to connect to the Symantec update service.
Project Setup
For the purposes of this article, I included a wrapper for the Symantec SSE APIs, av.jar, which has Symantec Java APIs and serves as a client to the SSE server and takes care of all communications with the server. Please refer to the download source section. The av.jar should be included in the Java CLASSPATH to work with the SSE. This jar contains a class called AVClient that takes care of actually sending the files to SSE as byte arrays and returning the result.
In my project setting, I added three variables to be accessed via the System.getProperty mechanism. For example:
AV_SERVER_HOST=192.168.1.150
AV_SERVER_PORT=1344
AV_SERVER_MODE=SCAN
The AV_SERVER_HOST is the host name or IP of the machine where Scan Engine is installed.
The AV_SERVER_PORT is the port where Scan Engine listens for incoming files.
The AV_SERVER_MODE is the scan mode which can be:
•     NOSCAN: No scanning will be done (any keyword that does not start with "SCAN" will result in ignoring the call to the Scan Engine and no files will be transferred for scanning).
•     SCAN: Files or the byte stream will be scanned, but the scan engine will not try to repair infections.
•     SCANREPAIR: Files will be scanned, the scan engine will try to repair infections, but nothing else will be done.
•     SCANREPAIRDELETE: Files will be scanned, the scan engine will try to repair infections, and irreparable files will be deleted.
Note: For the file stream (byte array) scanning, the only meaning full values are "SCAN" and "NOSCAN".
Using the SSE Scanning Java APIs
In any class where scan is required, call the scanning API provided in the AVClient object located in the av.jar. The AVClient object will establish connection to the Scan Engine server and has the following APIs:
Figure 2: The significant APIs for the communication with to the Scan Engine Server.
If scanning a file on the file system, in SCAN only mode, use the call that accepts filename only.
If scanning a file on the file system, with SCANREPAIR or SCANREPAIRDELETE, use the call that accepts input and output file names.
If scanning an in-memory file (byte array), use the call accepting byte array.
For example:
import com.av.*;
Initialize setup parameters:
static String avMode =
(System.getProperty("AV_SERVER_MODE") != null)
? (String) System.getProperty("AV_SERVER_MODE") : "NOSCAN";
static boolean scan = avMode.startsWith("SCAN");
static String avServer =
(String) System.getProperty("AV_SERVER_HOST");
static int avPort =
Integer.parseInt( (String) System.getProperty("AV_SERVER_PORT"));
Scan check example for an in-memory file byte array:
public void scanFile(byte[] fileBytes, String fileName)
throws IOException, Exception {
if (scan) {
AVClient avc = new AVClient(avServer, avPort, avMode);
if (avc.scanfile(fileName, fileBytes) == -1) {
throw new VirusException("WARNING: A virus was detected in
your attachment: " + fileName + "<br>Please scan
your system with the latest antivirus software with
updated virus definitions and try again.");
Note that if you are using this code inside of the MVC handler, you can throw a custom VirusException and check for it in the calling method and perform any necessary cleanup. I have included the class in the AV Jar as well.
For example:
catch (Exception ex) {
logger.error(ex);
if (ex instanceof VirusException) {
// do something here
else {
// there was some other error – handle it

d)     my2.java – This is the class file I wrote to test that I am able to send a file and scan it and see the output in the JDEVELOPER. In this case the file is stored on the filesystem of the client machine. JDEVELOPER should be able to see the file.
NOTE:
“EICAR.com” is the test file downloaded from Symantec site to test a non malicious virus file. I n order to be able to test it like this, the Antivirus program running on your machine should be disabled, or else Antivirus will kick in and delete the file. In the first place you will not be able to download the test virus file either with anti virus running on the machine you are downloading to.
package com.av;
import java.io.*;
public class my2 {
static int my_return = 0;
* @param fileBytes
* @param fileName
* @return
public static int scanfile(String fileName){
String avMode = "SCAN";
boolean scan = avMode.startsWith("SCAN");
String avServer = "xx";--avserver ip address
int avPort = 1344;
int the_return = 0;
if (scan) {
AVClient avc = new AVClient(avServer,avPort,avMode);
the_return = avc.scanfile(fileName);
if (the_return == -1) {
return (the_return);
} else

byte[] b1 = new byte[4];
b1[1] = 68;
my_return = scanfile("c:\\eicar.com");
System.out.println(my_return);
e)     Then finally we have my1.JAVA, which takes the filename, and it’s contents in the bytes form and scans the file. The reason for this method is we are not storing the file on the filesystem, it is read into the memory and only if it is clean, it is put into the database or else notify the user.
package com.av;
import java.io.*;
public class my1 {
static int my_return = 0;

int the_return = 0;
if (scan) {
AVClient avc = new AVClient(avServer,avPort,avMode);
// File file = new File(fileName) ;
//byte[] fBytes = getBytesFromFile(file);
the_return = avc.scanfile(fileName, fileBytes);
if (the_return == -1) {
return (the_return);
} else
{return (the_return);}
my_return = the_return;
return (the_return);
// Returns the contents of the file in a byte array.
* @param file
* @return
* @throws IOException
public static byte[] getBytesFromFile(File file) throws IOException {
InputStream is = new FileInputStream(file);
// Get the size of the file
long length = file.length();
// You cannot create an array using a long type.
// It needs to be an int type.
// Before converting to an int type, check
// to ensure that file is not larger than Integer.MAX_VALUE.
if (length > Integer.MAX_VALUE) {
// File is too large
// Create the byte array to hold the data
byte[] bytes = new byte[(int)length];
// Read in the bytes
int offset = 0;
int numRead = 0;
while (offset < bytes.length
&& (numRead=is.read(bytes, offset, bytes.length-offset)) >= 0) {
offset += numRead;
// Ensure all the bytes have been read in
if (offset < bytes.length) {
throw new IOException("Could not completely read file "+file.getName());
// Close the input stream and return bytes
is.close();
return bytes;
// public static void main(String[] args) throws Exception {
//System.out.println("Hi there in Main");
// File file = new File() ;
// byte[] b1 = getBytesFromFile(file);
//System.out.println(b1);
// my_return = scanfile(,b1);
//System.out.println(my_return); }
Finally , you have the exceptions file,
e) package com.av;
public class VirusException
extends Exception {
public VirusException() {
super();
public VirusException(String text) {
super(text);
Once you have all these classes, you can use JDEVELOPER , to load these classes into the database: This is as follows:
Right click on the project, which has all these classes.
NEW -> deployment profiles -> load java and stored procedures.
When you are created deployment profile, you have to specify,
Loadjava options.
-f, -v (check the check boxes)
Under privileges:
-s – specify database schema these classes are loaded into
-s – create sysnonym check box
-g – grant to public or any specific users per your policy.
Under Resolver,
-r and –o (check the check boxes)
I accepted the default name storedproc1. Then you right click on the storedproc1.deploy, deploy to whichever database connection you created.
And then, In order to access this java class we need a pl/sql wrapper as follows:
create or replace package my1 is
function mycheck (pfilename in varchar2, psize in number)
return number;
end my1;
create or replace package body my1 is
     function mycheck (pfilename in varchar2, psize in number)
return number is
language java
     name 'com.av.my1.scanfile(java.lang.String, byte[]) return int';
     end my1;
And the code is invoked from sql plus as follows:
Select my1.mycheck(“filename”, “filebytes”) from dual;
One important catch in the above method is to send the filename and filecontents in bytes form. In order to send the file contents as filebytes, you will need another java class and load into the data base as described above.

Having main method helps you to run the file in JDEVELOPER or using JAVA.
DO not forget to load this class into the database.
And you create the pl/sql wrapper again as follows:
create or replace FUNCTION TOBY (pfilename in varchar2) RETURN VARCHAR2 iS
language java name
'ReadFileIntoByteArray.chk_file(java.lang.String) return byte[]';
And you call the function from sqlplus as follows:
Sql>Set serveroutput on size 20000;
Sql> call dbms_java.set_output(20000);
Sql> Select toby(“filename”) from dual; --
this file should be accessible, I mean you will not be able to send a file on your pc, from sql plus as sql/plus is running on your db server.
You will be able to see the output in sql plus:
If you are running it from the APEX:
When we use file browser widget from APEX, the file is stored in APEX_APPLICATION_FILES table. And we retrieve that into a variable and pass this variable to the function as follows:
DECLARE
scan_failed EXCEPTION;
x varchar2(400);
z number;
BEGIN
select filename into x from wwv_flow_files where name = :P1_FILE_NAME;
select my1.mycheck(x,toby(x)) into z from dual;

Can't print scanned pdf files Xerox 3450 Adobe Pro and Reader 9

I have a user that cannot print PDF's made up of scanned images to a network printer.
The job goes to the printer and spools up but hangs at either 64kb or 255kb and then errors out.
Even if I print just one page, it does the same thing.
Folks with Acrobat Pro 8 or Reader 8 can print the same file to the same printer with no problems.
OS: XP
Network Printer: Xerox Phaser 3450 PS
Adobe: Reader 9.1.3 and Acrobat Professional 9.1.3
I have tried the following:
On the Xerox 3450 PS Printer:
- disabling Advanced Printing Options
- changing Post script options to: EPS, optimize for speed, optimize for portablity
- reloading the printer drivers
- unmapping/remapping the printer on the customer's system.
In the Reader and Acrobat Pro print options:
- print only Document rather than Document and Markups
- print as image
- unchecked 'convert to true type1'
- changed options to Send for each page, send by range,
- tried using Language level 2
- reinstalling Adobe Reader 9
This happens once the customer is upgraded to Adobe Reader 9. If I disable the 'Advanced Printer options' he can print OCR/Text PDF files but cannot print even a single page Scanned image PDF file. The spooler hangs at 255kb and then the print job errors out.
I confirmed this same issue on multiple machines and on other Xerox 3450 printers on multiple print servers. It is the same for Adobe Reader 9 and Adobe Acrobat Pro 9.
The machines and users are in different parts of the country on different print servers but the symptoms are the same: after being upgraded to Adobe Reader 9.1.3 or Adobe Acrobat Pro 9.1.3 they cannot send certain PDF files (so far just scanned image files) to a Xerox 3450 PS network printer.
Any suggestions on what to try next would be appreciated.

This problem plagued me for several weeks, until I found a solution that has allowed me to print scanned documents as quickly as a text document.
I have confirmed this worked on several network X3450 printers using Adobe Reader 9.1.3 and Adobe Acrobat Professional v9.1.3
In the Reader and Acrobat Pro print options:
    Click on the Advanced button and uncheck "Print as image" if it's checked.
    Click on "Let printer determine colors" to enable this option
    Click OK and Print.
After making this change, the document queued up and printed as fast a any text document printed.
I had a single page scanned text document which was about 19 KB, but when sent to the printer, the spooler grew from 10 MB to 50 MB to 80 MB, until an error occurred. Like you I tried many combinations until one worked. Then it was a matter of figuring out which setting was primarily responsible for allowing it to print quickly.
Most likely the problem is with the raster image processor (RIP) within Adobe Reader and Acrobat. By selecting the option to "Let the printer determine colors", it passes that part of the processing over to the RIP within the printer. Since the X3450 is not a color printer, the information is easily converted to grayscale and printed.
I'm still trying to absorb the information in the articles I have read so far, and I welcome any discussion about this from those more knowledgeable than I.
I hope this fix works for you as it did for me. I made a lot of happy customers once they were able to print since most of their documents are scanned rather than created with Acrobat.
