Struts and arabic characters

Dear All

I have a problem with struts i wish you could help me. I searched and tried a lot and I solved a part of the problem.

Arabic with Struts,

I'm building an application with Struts framework and MySQL the data inside the database is in arabic. arabic characters is displayed well and it works fine with my localhost tomcat but when I deploy the app. to the webserver on the host and test it this is what happened:

1- if i try to insert an item in arabic its saved with the fromat "???????" although it works fine with my local host and the detabases have the same configuration (Localhost database, webserver database).

 

2- this app. is for a restuarant so i display categories as links then when he click the speciefied link and i get the category name using the getParameter() method. and using the name i select all the items in this categoy. it works fine with english characters but with arabic it never returns any thing i refer this problem as the previous problem that getParam() method returns "???????" so it never finds category name "??????"

 

I'm using a filter to change the request and the response encoding to UTF-8 Encoding.

i don't know where the problem could be it works fine on my localhost machine.

I wish you could help me

thanks all
