I agree with you that I have to change my oracle encoding, and everything will work fine, but it is not easy to change the configuration of oracle in my company, cause we are upgrading an old system, and cause we are in an intermediat stage, I need to use oracle with us7ascii now, in the future we will change the configuration of oracle. and until we change the oracle configuration, I need to make advantage of the new versions of Java and tomcat. thanks

The JDBC driver will work very hard to force all your Arabic characters to turn into ? marks with this configuration. You must use UTF-8 or CP1256 or ISO-8869-6 in Oracle. -----Original Message----- From: Fadwa Barham [mailto:[EMAIL PROTECTED] Sent: Saturday, May 14, 2005 12:56 AM To: Tomcat Users List Subject: Re: Arabic encoding thanks for your reply. I agree with you that utf-8 encoding is suitable for all cases, but in tc4 with jdk1.3, I write the servlets and compile them and use data from oracle with us7ascii encoding, and I don't set any encoding except: pw.println("content=\"ar-sa\">"); pw.println("content=\"text/html;charset=windows-1256\">"); and the page display all the characters correctly. I think sun microsystems and tomcat made changes to the new packages about encoding. but how to deal with the new changed? Is there special setup I've to do? thanks Fadwa Mark Thomas wrote: There are lots of potential pitfalls when using non-default character encodings. It is easy to make mistakes both with Tomcat settings and with your code. To sort out the tomcat settings, get the following index.jsp to work for whatever text you supply to the form. I have tested this with the latest TC4 and TC5 code and it works for me with any text I choose to enter. Once you have this working, you can look at your application and see what is different.
