Multi language translation

Dear All,
I am using qt-embedded-linux-opensource-src-4.5.3 for my development.
I want to use multi language conversion,
I am doing in my application
fun()
{
{
QTranslator mTranslator;

QString msStrLanguage[13];

msStrLanguage[0]= QString(ENGLISH_QM);
msStrLanguage[1]= QString(GERMAM_QM);
msStrLanguage[2]= QString(NETHER_QM);
msStrLanguage[3]= QString(SPAIN_QM);
msStrLanguage[4]= QString(FRANCE_QM);
msStrLanguage[5]= QString(ITALIA_QM);
msStrLanguage[6]= QString(SWEDEN_QM);
//msStrLanguage[6]= QString(POLAND_QM);
msStrLanguage[7]= QString(PORUTO_QM);
msStrLanguage[8]= QString(RUSSIA_QM);
msStrLanguage[9]= QString(TURKEY_QM);
msStrLanguage[10]= QString(TAI_QM);
msStrLanguage[11]= QString(CHINA_QM);
// msStrLanguage[12]= QString(JAPAN_QM);
msStrLanguage[12]= QString(KOREA_QM);

QString path ="/system/"+msStrLanguage[12] ;
//path.append(Qtopia::qtopiaDir());
//path.append(msStrLanguage[12]);

qDebug("\n\n\n------- %%%%%%% $$$$ ( load path) 222 = %s \n\n",qPrintable(path));
mTranslator.load(path);

qApp->installTranslator(&mTranslator);
}

after this i am calling like

m_pLabelHelpTools->setText(qApp->tr("Enter")); this for language translation.
In target i have copied the .qm files with same /system/i18n/*.qm files.

When i am calling the function its not getting translating the string.

When i do configuration for qt in my build server i have not done any thing specially for translator

So i need to add any thing in code path first, before do qmake?
or what went wrong i am doing...?

Please any one help me to make it work.
Many many thanks in advance...for ur help.
