This utility converts unicode escape strings in a file to UTF-8 encoded. Suppose you received a properties file with contents like:
# @(#)codepoint_zh_CN.properties 1.4 05/09/27
#...
You can use this utility to convert it to UTF-8 and view or edit.
import java.io.*;
/**

This utility is equivalent to:
native2ascii -reverse -encoding utf-8
using the standard Java native2ascii utility.

The -d switch for cURL sends HTTP POST with data from the command line. To verify the data being posted, this is a CGI script that echos the data back:
#!C:/perl/bin/perl.exe ## ## echo -- echos ... Examples: POST data from command line: C:\>curl -d input1=value1^&input1=value2 http://lo... POST data from stdin (with @ before the - symbol): C:\>curl -d @- http://localhost/cgi-bin/echo.pl ... POST data from a file (with @ before the - symbol and input redirect): C:\tmp>cat data.txt abcd 1234 xyz ... For some reason, @ with file name didn't work as expected: C:\tmp>curl -d @data.txt http://localhost/cgi-bin/... One thing to notice is that cURL removes the new line characters when posting (thus the echo back is only one line instead of three). This can...

cURL is a command line tool for transferring files with URL syntax. The main purpose and use for cURL is to automate unattended file transfers or sequences of operations.
It's really easy to see HTTP headers with curl:
C:\>curl --head http://www.google.com
HTTP/1.0 ...
or, headers and page together (dump headers to stdout):
$ curl --dump-header - http://www.google.com HTTP/...

Use useradd to add a user (the switches are not required, but it's a good idea to give them. For example, without -m you'd create a user without a home directory):
# -d switch specifies user home directory
# -m ...
You also need to use the passwd command to set a new password before the user can log in.
To delete a user, use the userdel command:

The caret ^ is DOS command line escape character.
Example 1: echo < and > as is, not interpreting them as input/output redirect.
@rem sign an XML file. Requires Java class utils.x...
Example 2: treat & literally, not as the special character to combine two commands.
@rem search "dos command line" in Google.

It seems that the key to aligning a checkbox with its label lies in the line-height property of the label. This simple HTML snippet aligns well:
<!DOCTYPE HTML> <html> <head> <style typ... which is rendered like this: Change the font size of the label to 12px throws off the alignment: label.checkbox { font-size: 12px; di... In case 1, the height of the checkbox is 13px with 3px top and bottom margin, for a total of 19px , which is exactly the height of the label div. As can be seen from Firebug : Checkbox layout Label layout In case 2, the height of the label div shrinks to 15px , while the height of the checkbox remains the same: Checkbox layout Label layout And...

In this note I'll show you how to create and package a JSP custom tag. The purpose of this tag is to display a random splash image for a home page, among a set of images. We should be able to add or delete candidate splash images from the WAR archive without the need to change the JSP. This is the intended use of the tag:
<%@ taglib uri="http://custom.tag.com/demo" prefix... In the above example you provide a set of images named splash*.png (e.g., splash1.png, spalsh2.png, ...), and the tag will pick a random one to display when the JSP is rendered. Let's get started. I'll use Maven for this purpose. Create the standard Maven directory structure ./pom.xml ./src ./src/main ./src/main/jav... pom.xml <project xmlns="http://maven.apache.org/POM/4.0.0"... SplashTag.java package tagdemo; import java.util.ArrayList......

This is a utility to generate SQL insert statements for Oracle for one table, or a set of tables. It doesn't cover all possibilities but should be good enough for most cases.
import java.io.*;
import java.sql.*;
import ...
To generate insert statements for multiple tables, simply put the table names in a file, one per line, and use the -f switch.

From X(7) manual page : Although the layout of windows on a display is controlled by the window manager that the user is running (described below), most X programs accept a command line argument of the form -geometry WIDTHxHEIGHT+XOFF+YOFF (where WIDTH, HEIGHT, XOFF, and YOFF are numbers) for specifying a preferred size and location for this application's main window. The WIDTH and HEIGHT parts of the geometry specification are usually measured in either pixels or characters , depending on the application. The XOFF and YOFF parts are measured in pixels and are used to specify the distance of the window from the left or right and top and bottom edges of the screen, respectively. Both types of offsets are measured from the indicated edge of...
