AJAX AutoSuggest with Parameters in Greeks

Usage of the following control:
http://www.brandspankingnew.net/archive/2006/08/ajax_auto-suggest_auto-complete.html

Some changes in Javascript bsn.AutoSuggest_2.1.3_comp.js in order to support Greek language.

Replace twice the
encodeURIComponent(this.sInp)
with
encodeURI(encodeURI(this.sInp))

Read the greek parameters using in a java bean the following code:
try {
request.setCharacterEncoding("UTF-8");
nm = request.getParameter("nm");
nm = java.net.URLDecoder.decode (nm, "UTF-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}

Struts 1.x + Ajax + Greek Language (UTF-8)

In order to support UTF-8 (greek characters) in the parameters of a URI with AJAX, you have to do the following steps:

1. In the AJAX .js file, the function that requests data from the server...

function getDataFrom(str){
str = trim(str);

if ( str.length==0 ) {
document.getElementById(your_id).value = "";
return;
}

// 1. Create the XmlHttp Object
xmlHttp=GetXmlHttpObject();
if (xmlHttp==null){
alert ("Your browser does not support AJAX!");
return;
}

var url="your_struts_url_action.do?do=a&nm=" + str;

// SOS - Call twice the encoding function...
url = encodeURI (url);
url = encodeURI (url);

// 2. Event handler when readystate changes....
xmlHttp.onreadystatechange=your_function;

// 3. Request info from the db
xmlHttp.open("GET",url,true);
xmlHttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded; charset=utf-8");
xmlHttp.send(null);
}


Step 2: In the Action that you call from the AJAX function above, read the parameter and decode it:

try {
request.setCharacterEncoding("UTF-8");
name = request.getParameter("nm");
name = java.net.URLDecoder.decode ( sYphresia, "UTF-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}

mySQL - UTF-8 for JSP and Tomcat

How to display UTF-8 characters in Tomcat using MySQL as the data source!

1. Make sure your MySQL database is using the UTF-8 character set.

2.Tell the JDBC connector that it has to talk to the database using UTF-8.
To do this add useUnicode=true&characterEncoding=UTF-8 to the connection URL in the JDBC configuration. Your connection URL will look something like this: jdbc:mysql://localhost:3306/mydatabase?useUnicode=true&characterEncoding=UTF-8.

3. Make sure the browser knows that what it's receiving is actually UTF-8.
In your JSP files add <%@ page contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %>at the top.
In your Servlets, make sure the right HTTP headers are sent back to the client by adding the line response.setContentType("text/html;charset=UTF-8");.
Of course, you'll have to use another MIME type than text/html if you're not going to display HTML.

4. Tell Java that you're using UTF-8 by configuring the Java options.
Add the parameter -Dfile.encoding=UTF-8 to your Java options, either in the catalina.bat file or by clicking on the Java tab in the Monitor Tomcat program.

5. if you're using Struts to handle web forms - is to make sure all input from the client is converted to UTF-8.
This is done with a little bit of coding and a configuration change

Format dates and numbers

public String FD(String strDate){
// Converts a date from 1900-01-01 to 01-01-1900 and vice versa ....
if ( strDate != null ) {
String newDate[];
String strNewDate = "";
int indx =0;

newDate = strDate.split("-",3);

for (indx = 2; indx >=0; indx-- )
strNewDate = strNewDate + newDate[indx] + "-";
return(strNewDate.substring(0, strNewDate.length() - 1));
}
else
return ("");
}

public String FC(String strMoney){
// Converts a string from 00000000,00 to 00.000.000.000,00

if ( strMoney != null ) {
BigDecimal amount = new BigDecimal(strMoney);

NumberFormat nf = NumberFormat.getInstance();
nf.setMinimumFractionDigits(2);
nf.setMaximumFractionDigits(2);
String res = nf.format(amount);
return( res );
}
else
return ("");
