Problem using a vector of strings as patterns to search a text file

Ideas? Goal is to use several patterns from one file to search for matches in a second file, one pattern at a time. I have added the file of patterns to a vector and created an iterator to grab each pattern successively. I also can effectively search for matches in the second file, but can't seem to find a way to combine them. I've tried nested while(s) in both orders without success.
Thank you for any suggestions.

It sounds to me like it should work. What does your search code look like?

Problem in setting vector or string[] as the "value object" in hashmap

Hey I am new to this forum.
I am doing a project in which i need to store a array of strings as "value object" for a unique key in hashmap.
as I populate the hashmap from external file according to key and setting the string[]. The hashmap is taking the value field same for each entry i.e the last field as i keep updating the same variable and then putting it into hashmap.
Please give solution to my problem???
if question not clear,please tell me- i will add more information
Edited by: AnkitNahar on Apr 4, 2009 8:06 AM

I tried using the method suggested by you...but it is of same case as using the string[].
I need to loop the statements in which the hashmap is populating so cant change the variable names in the dd.put() statements. When the below code executes it shows the same set of string for both the keys, that was the problem i was facing with string[].
here is the example with two entries....same thing in looping.
HashMap<String,Set<String>> dd=new HashMap<String,Set<String>>();
String word = "Hello";
Set<String> alternativeWords = new HashSet<String>();
alternativeWords.add("Hi");
alternativeWords.add("Yo");
dd.put(word, alternativeWords);
alternativeWords.clear();
alternativeWords.add("hey");
word="yep";
dd.put(word,alternativeWords);
System.out.println(dd.get("Hello").toString());
System.out.println(dd.get("yep").toString());

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.

Problems using parseEscapedXML with a string containing ampersant

Hi,
I'm trying to pass a string with a url in it to the parseEscapedXML funtion. The string looks like this:
http://www.test.com/test&id2
I get an error message saying the entity id2 cannot be resolved and that it must end with ;
I tried escaping (replacing & by &) and double escaping (&amp;) but that didn't solve anything.
Any suggestions?

I'll be a little more specific.
Our service takes several input parameters (all strings, amongst them is the url parameter).
We use a file template which is an xml, containing this kind of stuff:
<element>$url$</element>
We load the template into a string, then use java string replacement and getVariableData to replace the template stuff with the values that were received from the input.
To finalize, the string, forming a perfect xml, is parsed with parseEscapedXML and passed on to another service.
To sum up: if url contains
a [AMPERSANT] a
it failes.
if url contains
a [ESCAPED AMPERSANT] a
it also fails.
So Marc, I think you suspected that I had some other characters causing the problem, but they aren't there. Unless you mean I should escaped my whole template ...

Match a data string in each record of two text files

What is the easiest way to match a string of characters in each record of File1.txt with the same string in File2.txt and write out those records that match from File1.txt to File3.txt? I don't want to buy an expensive application and I don't want to write a script from scratch.
Thanks

Take a look at the diff utility in the Terminal. A google search for it should provide enough info on how to use it. Basic is diff file1 file2
Or, type "info diff" in the command line.
Oops. I read too much into your request and got it backwards. Seems grep or awk would work for what you want.

How can I use the FTP server on Oracle XML DB for plain text files?

Hi,
I need to generate comma separated files for download via FTP. The files are generated from Oracle Table data and should be published on a FTP Server. Would it be able to use the FTP Server on Oracle XML DB?
If not, any suggestions?
Thanks
Frederik Christensen

You can create a temporary CLOB with your CSV content, and then folder the CLOB into the XDB repository with DBMS_XDB.createRESOURCE()...
This would work fine....

Not using an array of strings

how do I write a java method without using an array of strings?
for example:
import java.io.File;
public class rename
public static void main(String[] args)
File src = new File(args[0]);
File dst = new File("c:\\temp\\temp.txt");
boolean wasRenamed = src.renameTo(dst);
I don't want to have main use an array of strings but I want rename to work as a class

This is what I changed it to and am getting an -- Exception in thread "main" java.lang.NoSuchMethodError: main
Sorry this is my first java program
import java.io.File;
class App {
     private App() {
          super();
     static final public void main(final String[] args) {
          switch (args.length) {
               case 1:
                    try {
                         Rename rename = new Rename();
                         rename.rename("c:\\felss\\charles.txt.bak"); // see, it's kind of silly to have same names for class and method
                         System.exit(0);
                    catch (Throwable e) {
                         e.printStackTrace();
                         System.exit(1);
                    break;
               default:
                    System.err.println("Usage: java App [new name]");
                    System.exit(1);
public class Rename {
     public Rename() {

          File src = new File(newName);

Problems using codeBase in policy file

Hi,
I'm experiencing problems using the codeBase option with the grant option in my .policy file.
I want to start a 'manager' which has limited access to files. This manager starts workers (threads) who need complete access to... everything. I know I need to use the codebase identifier to separate those two groups of rights, but I don't seem to get the codebase right. The worker threads don't get any rights at all. The manager works fine (without any codebase definition).
I've used full and relative pathnames, with and without '/-' or '/*'
The file I use currently is (slightly truncated :), pathnames are package names:
grant codeBase "file:com/response/timber/broker/*" {
permission java.security.AllPermission;
grant {
permission [..].FilePermission "manager.properties","read";
permission [..].SocketPermission "localhost","connect,[..]";
permission [..].FilePermission "com/[..]/jaxb.properties","read";
According to the various examples on the Internet, it should work, but ofcourse it doesn't. Could the use of threat have any influence on the defined security?

All I can say is I hope someone gives you
(and indirectly me) the answer. I've got a
serious problem granting special permissions
in Sun ONE to a servlet and it's jars.
One strange thing (to me), is that the format
for the .policy file seems quite different between
say Tomcat and Sun One. Things that work in Tomcat
don't work for Sun ONE. But I thought the underlying
vm et al was all the same! So did I... Why does
this have to be so Opaque? Why different syntax
platform to platform? Its all Java!

          } catch (IOException ioe) {
               System.out.println("IO Exception " + ioe);
The problem with your code is that you should first check whether there are any tokens before doing nextToken().

I have a couple of string to write into text file
---- for example--
String test1="aaa";
String test2="bbbb";
String test3="c";
String test4="dd";
--- condition to write into text file....
test1 has to write between 1 - 5 position.
test2 has to write between 6 - 15 postition.
test3 has to write between 16 - 10 position.
test4 has to write between 11 - 15 position.
how can i write those strings into a certain position?
how can i write those strings for 3 times in a text file?(make 3 rows)

figure out how write them into a string, then use my helper util class like this:
String str = "some\nstuff\nhere";
ASCIIFile file = new ASCIIFile("c:/somefile.txt");
file.setContents(str);
//done, file written!code for ASCIIFile can be found here:

Problem using the setPage(String url) of JEditorPane

Hi all !
I'm developping a text file generator which generates a text file and use a viewer to display the content of this text file.
The first time, it works correctly, it displays the text file content but the others times it doesn't work correctly, the first text file content remains displayed.
It seems that the setpage(String url) method doesn't work correctly.
Does anyone know this problem ?
In advance, thanks a lot.

hi,
there is some problem with JedtorPane when you update the page. Image or not updated all the time because the buffer keep the old image and does not update it. The problem is that class got to much protected field so you cannot change nothing. It is a bug since Two years and no body as correct it.

Use of Vector in undo operation ?

Hello,
I am developing simple paint program. And want to use undo redo operation for drawing in drawing canvas. Actually I have done it with the help of Vector. But the problem is that it is not working properly. The first drawn shape is not removing with this operation and also the problem is that When i am using CTRL+Z for undoing last drawing. It is not removing last drawn shape with first undo operation. Let me know that what is the exact problem in my coding. I am not fully java programmer. So please tell me what to do for that. I want to draw n level of drawing on drawing canvas and also want to perform n level (first drawn shape) undo actions. And also want to know how to make redo button for same coding only use of Vector or ArrayList.
My code is here:

}This is complete code for undoing.
Any help will be appreciated.
Thanks in advance.

The example code is set up for a protocol completely different than what you are doing, so you can't simply copy it and hope it works. The example code expects that the other side will send a 4-byte header containing the number of data bytes that follow, then send the data. The example code first reads that 4-byte header, casts it to an integer, and reads that number of bytes (the second Bluetooth Read).
When you run this with your device, the first read gets your 4 bytes - FF FF 22 33 - and converts that to an integer. 0xFFFF2233 is decimal 4294910515. So you then try to read this huge number of bytes and you get an error - looks like error 1, an input parameter is invalid, because you can't read 4GB at once. You can probably get your code working with a single Bluetooth Read, with a 1 second timeout (because you have a 1 second delay between packets). You'll want to wire in some number of bytes to read that is at least the size of the largest packet you ever expect, but don't use a ridiculously huge number that generates an error. LabVIEW will return as many bytes as are available when the timeout expires, even if it isn't as many as you asked to read (you might also get a timeout error, though, which you'll need to clear). You can then do whatever you need to do with that data - search for FF FF, typecast anything after that to array of U16, display it.
The output of the Bluetooth Read is a string, but it's not text - it's exactly the bytes that were sent. The Y with the dots over it is the way ASCII 255 (0xFF) displays (at least in that font). ASCII 34 (0x22) is ", and ASCII 51 (0x33) is the number 3.
