Problem in loading chinese properties file [*.properties]
Hi !
I want to load the "Chinese.properties" file in object of Properties Class. "Chinese.properties" is a unicode based language file. This file includes keys in english and values in chinese [actual representation not unicodes]. When I load it in my object of properties. It is not loading properly. Here is my sample code:
publicclass ASC_LoadLanguage{
publicstatic String m_strLangName;
publicstatic Properties m_objCurrentLang =new Properties();
publicstatic String m_strEncoding ="Unicode";
public ASC_LoadLanguage(){
}
publicstaticvoid main(String[] args){
try{
ASC_LoadLanguage obj_LoadLanguage =new ASC_LoadLanguage();
obj_LoadLanguage.loadLanguage(args[3]);
UIManager.put("OptionPane.messageFont",new Font("Arial Unicode MS", Font.PLAIN, 11));
//This part of code is not displaying any thing. actually it contains null
//The name of key is accurate. Fetches data for other languages e.g. English, //Spanish.
JOptionPane.showMessageDialog(null, m_objCurrentLang.getProperty(ASC_Keys.KEY1));
}
catch (Exception ex){
ex.printStackTrace();
}
}
publicvoid loadLanguage(String a_strLanguagePath){
try{
System.out.println("Loading language: " + a_strLanguagePath);
InputStream is =new FileInputStream(a_strLanguagePath);
m_objCurrentLang.load(is);
is.close();
is =null;
System.out.println("Current language to be used is: " + a_strLanguagePath);
}
catch (Exception a_e){
a_e.printStackTrace();
}
}
}
Please help me in this regrad. If I'm doing anything wrong.
Regards,
KS.

> "Chinese.properties" is a unicode based language file. Okay. But does it follow the rule that it has to be encoded in ISO-8859-1 with Unicode escapes for non-Latin-1 characters? The API documentation for the Properties class explains this in detail.
Thanx for your interest. I have resolved this Issue by this:
I have used *.xml as my properties file instead of using *.properties.
Here is the sample code:
public class ASC_LoadLanguage {
public static String m_strLangName;
public static Properties m_objCurrentLang = new Properties();
public static String m_strEncoding = "Unicode";
public ASC_LoadLanguage() {
}
public static void main(String[] args) {
try {
ASC_LoadLanguage obj_LoadLanguage = new ASC_LoadLanguage();
//obj_LoadLanguage.loadLanguage(args[3]); //Loading from "*.properties" file
obj_LoadLanguage.loadLanguageFromXML(args[4]); //Loading from "*.xml" file
m_objCurrentLang.list(System.out);
UIManager.put("OptionPane.messageFont", new Font("Arial Unicode MS", Font.PLAIN, 11));
JOptionPane.showMessageDialog(null, m_objCurrentLang.getProperty(ASC_Keys.KEY1));
}
catch (Exception ex) {
ex.printStackTrace();
}
}
public void loadLanguageFromXML(String a_strLanguagePath){
try {
System.out.println("Loading language: " + a_strLanguagePath);
InputStream is = new FileInputStream(a_strLanguagePath);
m_objCurrentLang.loadFromXML(is);
is.close();
is = null;
System.out.println("Current language to be used is: " + a_strLanguagePath);
}
catch (Exception a_e) {
a_e.printStackTrace();
}
}
public void loadLanguage(String a_strLanguagePath){
try {
System.out.println("Loading language: " + a_strLanguagePath);
InputStream is = new FileInputStream(a_strLanguagePath);
m_objCurrentLang.load(is);
is.close();
is = null;
System.out.println("Current language to be used is: " + a_strLanguagePath);
}
catch (Exception a_e) {
a_e.printStackTrace();
}
}
}

Looks like you've already resolved the issue using the loadFromXML() method, so this is fyi.
In the upcoming JDK 6, an overloaded method of Properties.load(), which takes a Reader instance, was added. So Properties files in any encoding can be loaded into Properties directly with this method.

Hi
I'm doing the following task, here is sample code:
//import statements
import java.awt.*;
import java.io.*;
import java.util.*;
import javax.swing.*;
//args[0] is not null, it contains "default.xml"
loadLanguageFromXML(args[0]);
public void loadLanguageFromXML(String a_strLanguagePath){
try {
m_objCurrentLang = new Properties();
System.out.println("Loading language: " + a_strLanguagePath);
InputStream is = new FileInputStream(a_strLanguagePath);
//exception is coming at the line below
m_objCurrentLang.loadFromXML(is);
is.close();
is = null;
System.out.println("Current language to be used is: " + a_strLanguagePath);
}
catch (Exception a_e) {
a_e.printStackTrace();
}
}
But I'm having following exception at the line of code:
m_objCurrentLang.loadFromXML(is);
java.util.InvalidPropertiesFormatException: java.lang.NullPointerException
at java.util.XMLUtils.load(Unknown Source)
at java.util.Properties.loadFromXML(Unknown Source)

... 4 more
This exception is occurring when I want to load XML-property file. Note that It is running fine in my IDE, but when I created its release and run from a *.bat file then it is giving above defined exception.
Here is code of my *.bat file
Batch File name...LoadXMLLang.bat

JRE\bin\javaw -classpath "lib\asc_csv2properties.jar" ASC_LoadLanguage "default.xml"

Please help me in this regard, because I'm unable to resolve the issue.
