Is it possible to find and Replace a string inside a textfile using JSP?

FileInputStream fs = new FileInputStream("/opt/Abhishek/software/tomcat/webapps/AMS/listpass");
DataInputStream in1 = new DataInputStream(fs);
while (in1.available() !=0)
String str1=in1.readLine();
StringTokenizer st1 = new StringTokenizer(str1);
String node=st1.nextToken();
if (node.equals(sports))
String pass=st1.nextToken();
out.println (""+sports[i]+" ");
out.println("**Your Required Password**");
out.println(pass);
out.println(" ");

Hi ,
I have a text file (named listpass in the above code) inside tomcat-webapps folder containing a node name and its password.You could see the path of the text file at the starting line of the code.The Scene behind the program is once the particular node is clicked the password is retreived for the user against the particular node.What i would need is to change the password in the text file once it is retreived. So i would need to find the password that is retreived recently and change that one with a randomnly generated new password in the text file.
So can i do this?Is it possible to search for the string in the text file and replace that with a new one using JSP.For your note i am running all my HTML amd JSP inside the same folder where i have the text file in which the string has to be replaced .
Could anyone give your comments on this please?

Nasty in so many ways.
First off you shouldn't be doing stuff like this in a JSP. JSPs should just build HTML, use a Servlet and then pass data to a JSP for formatting.
Web applications are multi-threaded, so you have to consider what happens if several of these transactions come in at the same time, each trying to change the same data file.
It's not practical to amend text files in place, generally you have to create a new version of the file for each change because if the size of a password changes the subsequent bytes of the file would all need moving.
Use a database. Databases are designed to deal with these issues and there are perfectly good free ones around like Derby, MySQL and H2.

[Forum FAQ] How to find and replace text strings in the shapes in Excel using Windows PowerShell

Windows PowerShell is a powerful command tool and we can use it for management and operations. In this article we introduce the detailed steps to use Windows PowerShell to find and replace test string in the
shapes in Excel Object.
Since the Excel.Application
is available for representing the entire Microsoft Excel application, we can invoke the relevant Properties and Methods to help us to
interact with Excel document.
The figure below is an excel file:
Figure 1.
You can use the PowerShell script below to list the text in the shapes and replace the text string to “text”:
$text = “text1”,”text2”,”text3”,”text3”
$Excel
= New-Object -ComObject Excel.Application
$Excel.visible = $true
$Workbook
= $Excel.workbooks.open("d:\shape.xlsx")
#Open the excel file
$Worksheet
= $Workbook.Worksheets.Item("shapes")
#Open the worksheet named "shapes"
$shape = $Worksheet.Shapes
# Get all the shapes
$i=0
# This number is used to replace the text in sequence as the variable “$text”
Foreach ($sh in $shape){
$sh.TextFrame.Characters().text
# Get the textbox in the shape
$sh.TextFrame.Characters().text =
$text[$i++]
#Change the value of the textbox in the shape one by one
$WorkBook.Save()
#Save workbook in excel
$WorkBook.Close()
#Close workbook in excel
[void]$excel.quit()
#Quit Excel
Before invoking the methods and properties, we can use the cmdlet “Get-Member” to list the available methods.
Besides, we can also find the documents about these methods and properties in MSDN:
Workbook.Worksheets Property (Excel):
http://msdn.microsoft.com/en-us/library/office/ff835542(v=office.15).aspx
Worksheet.Shapes Property:
http://msdn.microsoft.com/en-us/library/office/ff821817(v=office.15).aspx
Shape.TextFrame Property:
http://msdn.microsoft.com/en-us/library/office/ff839162(v=office.15).aspx
TextFrame.Characters Method (Excel):
http://msdn.microsoft.com/en-us/library/office/ff195027(v=office.15).aspx
Characters.Text Property (Excel):
http://msdn.microsoft.com/en-us/library/office/ff838596(v=office.15).aspx
After running the script above, we can see the changes in the figure below:

Thank you for the information, but does this thread really need to be stuck to the top of the forum?
If there must be a sticky, I'd rather see a link to a page on the wiki that has links to all of these ForumFAQ posts.

Find and Replace text string in HTML

Opps... I hope this forum is not just for Outlook. My Html files reside on my hard-drive. I am looking for VBA code to open specified file names ####File.html and then find and replace text strings within the html for example "####Name" replaced
with "YYYYY"
I drive the "####File.html" names and the find and replace text strings from an Excel sheet. I am an artist and this Sub would give me time to paint instead of find and replace text. Thank you!

Hello Phil,
The current forum is for developers and Outlook related programming questions. That's why I'd suggest hiring anybody for developing the code for you. You may find freelancers, for example. Try googling for any freelance-related web sites and asking such
questions there.
If you decide to develop an Outlook macro on your own, the
Getting Started with VBA in Outlook 2010 article is a good place to start from.

How to find and replace any string between " "

Hi everyone,
Here my sample
String szTest;
szTest = "Yellow banana";
szTest = "Blue monkey";
szTest = "Red mango";
szTest is only needed when it's in testing progress. Now I want to put all of that in the /*comment*/ so the released program won't run those code any more (but still keep szTest so I can use it for future develop testing).
So Here what I want after using the Find and Replace Box:
//String szTest; //Manual
/*szTest = "Yellow banana";*/ //use find and replace
/*szTest = "Blue monkey";*/ //use find and replace
/*szTest = "Red mango";*/ //use find and replace
I think I can do this with Regular expressions or Wildcards. But I don't know how to find and replace any string between " and ".
Find: szTest = " ??Any string?? ";
Replace with: /*szTest = " ??Any string?? ";*/
Thanks for reading.

Hi Nathan.j.Smith,
Based on your issue, I suggest you can try the Joel's suggestion check your issue again. In addition, I find a MSDN document about how to use the Regex.Replace Method to match a regular expression pattern with a specified replacement string,
maybe you will get some useful message.
https://msdn.microsoft.com/en-us/library/xwewhkd1(v=vs.110).aspx
If the above suggestion still could not provide you, could you please tell me what language you use to create the program for finding and replace any string using regular expression so that we will find the correct programming develop forum to support this
issue?

Program for find and replace a string in all the reports in a package

Hello experts,
Is there any standard report or transaction provided by SAP which can be used to find a String in all the program in a package ?
As per my knowledge there is a program RPR_ABAP_SOURCE_SCAN which can search for a string in a package but this program doesnot support the replacement .
Any clue in this regard will be helpful.
Thanks
Vivek

Vevek, you are searching for something very very destructive.. do you realize that?
its better if you could explain us the requirement, by the way for a automated change you need to have INSERT REPORT called inside some program, so start searching that line if you can get it
else, write a piece of code for it..

Find and Replace a Blank in Load Rules

 Does anyone know if it is possible to find and replace a blank cell with a member name within Essbase Load Rules? My source data (a .txt file) has blanks within a single dimension that I need to replace with an Essbase member name so I can load it into the essbase cube. Until I add characters into the 'Find' window within Find and Replace, the option to add it in is greyed out. I am using Essbase 6.5.1 

From the DBag: Replacing an Empty Field with Text You may want to replace empty fields in a column with text. If, for example, empty fields in the column represent default values, you could insert the default values to replace the empty ones or insert #MI to represent missing values. Replacing an empty field with text requires several steps. To replace an empty field with text: Select the column containing the empty fields you want to replace. Choose Field > Create Using Text or click the Create Using Text button, . Enter the text to put in the new field. Enter a dummy string that is not in the selected column, such as "temp." Click OK. Join the new field with the column containing the fields to replace. Select both columns, choose Field > Join, and click OK. The previously blank fields now contain the dummy string you entered in step 3; for example, temp. Select the column containing the dummy string and choose Field > Properties or click the Field Properties button, . Click the Global Properties tab. Enter the text string you want to replace in the Replace text box. This should be the dummy string you entered in step 3; for example, temp. Now enter the text to replace it with in the With text box. This should be the final value you want to put in the fields, for example, default. Select the Match Whole Word. Click Add and then click OK. Now replace the extra dummy strings in the column with nothing. Choose Field > Properties or click the Field Properties button, . Click the Global Properties tab. Enter the dummy string in the Replace text box; for example, temp. Enter nothing in the With text box. Make sure the Match Whole Word option is not checked. Click Add and then click OK.

Find and replace string in file

hi,
i need to find and replace text (string) data in about 100+ files, i've decided to write a small java program to do it but i'm stuck on how to replace.
here is what i'm heading towards:
class ReplaceString {
BufferedReader in;
BufferedReader os;
public static void main(String args[]) {
    ReplaceString obj = new ReplaceString();
    obj.replace();
   void replace() {
     try {
       in = new BufferedReader(new FileReader("a.txt");
       os = new BufferdWriter(new FileWriter("a.txt");
       // read until end of file
       String currentLine = new String();
       while((currenLine=is.readLine()) != null) {
         // if matching text then replace????
         if(currentLine.equals("Version 001") {
            // how to now replace the Version 001 with Version 002???
     }catch(IOException e) {
        System.out.println(e);
        in.close();
        os.close();
     in.close();
     os.close();
}the above code i just typed so there might be errors, but looks ok to me, is there any way once i find the string i want to replace, to replace the string with another string. basically i want to replace all occurrences of the text "Version 001" with "Version 002"
Thank you.

Is it always true, as in your example, that the replacement is the same length as the existing string? If so, this one's easy.
Is it also true that you don't need to worry about 16-bit chars? (Again, as in your example.) If you're using just ASCII characters, this gets easier still.
1) Segregate the file I/O from the search/replace process.
2) Main becomes:
readFile();
replace( "this", "that" );
writeFile();Use a byte array buffer, defined in your main class. Fill it via the readFile() code. Use a RandomAccessFile, check its length() to allocate your byte array, then do a single read() to fill the buffer.
A brute force search will certainly work: scan for the first search character, then check the rest for a match, replace if you've got a match and continue scanning. Alternative if your file's aren't too big: create a String from the byte array:
// buffer is a byte array
String s = new String( buffer );And use the String.replaceAll() to do the search/replace. Recover the buffer with:
buffer = string.getBytes();A single write() and close() should handle the remaining work.

In the new Numbers, can I find and replace within formulas like I used to in Numbers'09?

I use Numbers with quite long formulas with reference to other tables. With Numbers'09, it was extremely useful to copy formulas and then use "find and replace" to change the terms within.
Did they remove this option? I don't seem to be able to do that with the new Version.
If it's still there, where do I find it?
If it's not there.... why would they remove it.
Thanks

Basically, I use it for payroll, taxes, and so on... I have one sheet per employee (which compiles their weekly payroll). I have then different sheets which makes the quarterly taxes calculation (state and federal taxes - 941, 940, W2, disability, UI, paystubs, tracks payments and deadlines, etc... ). It took me awhile to write all of the formulas, but now it does everything for me.
When I add an employee. I have to add a sheet, but also add a line in the calculation sheets. Because all the employee sheets are the same format, all I need to do (or used to now) was to copy the line above, and just change the reference name of the employee sheet within the formula (because there are several terms that are looked up, the reference name comes several time in the formula)... changing it manually is really annoying. What was taking me a minute or so, before, now takes me about 20 minutes. (between the different sheets, there are about between 75 to 100 changes in formulas per new employee - so the "find and replace" in formula only, was extremely useful).

Is any one has a better method using DW's "Find and Replace"

Using Templates with a 900 page site is a crime against
humanity. You reach
the optimal size for Templates between about 50 and 100.
The error you are getting suggests that there are coding
errors on the page
(perhaps even unrelated to ANY DW Template markup). We'd need
to see the
page to make progress with what that might be, as Alan says.

Possible to dock "Find and Replace" Window?

Is it possible to group the "Find and Replace" window in one
of the panels? I would prefer to have it at the bottom of my
workspace with Properties and Results.
Thanks!

It is indeed possible, providing whatever text is inside a tag of some sort. It could be in a list, heading, paragraph, div, etc... Use the Search: Specific Tag option. See screenshot (excuse the sloppy image).

How do I find and replace text in PHP files?

How can I in CS3 make sitewide changes to the text in PHP pages without changing variable names etc that have the same name?
For example if I have an installation of a PHP forum and I want to change every instance of the word 'forum' to 'message board'...
If I used the 'inside tag' search with " as the tag, then if "" contained a variable called 'forum' it would also be changed and therefore corrupt the code....
Is there a simple way around this?
Thanks!
I'm using CS3 on Windows Vista.

It looks like you're trying to find and replace source code, so you may be able to look at the various places that are looked at when finding and uncheck the ones that don't apply.
But, if it's all source code then that won't help. One thing that may work is to expand the search option - for example if the work "forum" that you're wanting to change it preceded by another word, or character or something that sets it apart, then do you find on that. You can expand that search phrase as far out in either direction that you need to to make it different, if of course that is practical in your situation.
The only other way I can think of is to somehow create an exception rule, but I'm not sure if that's possible or how to do it.

Using applescript for Find and Replace All in Pages 2.0

OK, here's another example. This one gets the text as a string and uses the offset property to find "[", presuming it to be a merge delimiter. (Pages' text doesn't support "offset of").
One failing of this scheme is that the offsets are incorrect if you have inline objects (pictures, shapes, tables, etc.). While it is probably possible to compensate for them, that's a trickier proposition.

property mergeText : {"[name]", "John Smith", "[address]", "1234 Anystreet"}

repeat with x from 1 to theCount by 2
if item x of mergeText = mergeWord then
return item (x + 1) of mergeText
end if
end repeat
-- If merge field is not found, delete it (replace it with the empty string)
return ""
end lookup
tell application "Pages"
repeat
tell body text of document 1
-- Get text as a string so that "offset of" can be used.
set allText to it as string
set startOffset to offset of "[" in allText

Folder action to find and replace text and change line feeds

I want to use a folder action to find and replace text and change Mac carriage returns to DOS line feeds inside text files.
The text to be replaced is: "/Users/wim/Music/iTunes/iTunes Music/Music" (without the quotes)
This text has to be removed (i.e. replaced by an empty string)
The text occurs many times within each file.
The files are playlists exported from iTunes in the M3U format (which are text files). They contain Mac carriage returns. These need to be changed to DOS line feeds.
I have found the following two perl commands to achieve this:
To find and replace text: perl -pi -w -e 's/THIS/THAT/g;' *.txt
To change carriage returns to line feeds: perl -i -pe 's/\015/\015\012/g' mac-file
I know that it's possible to make a folder action with Automator that executes a shell script.
What I want to do is drop the exported playlists in M3U format in a folder so that the folder action will remove the right text and change the carriage returns.
My questions are:
Is it possible to make a folder action that executes command line commands instead of shell scripts?
What is the correct syntax for the two commands when used in a folder action shell script? Especially, how do I escape the slashes (/) in the string to be removed?
Thanks for your help

Ok, I've include an applescript to run a shell command. The applesript command quoted form makes a string that will end up as a single string on the bash command line. Depending on what you want to do, you may need multiple string on the bash command lines. I've included some information on folder actions.
