Hello everyone!
I have a problem retrieving data (arabic data)from Oracle database. Bellow is the code for a testing page that should search for a giving name from oracle database and then disply it on the screan.
PS: even though the input is a correct data, the search doesn't give me anything back!
BTW, I'm using apache tomcat.
ANY HELP WILL BE GREATLY APPRECIATED!
