I am retriving data from oracle11g and displaying the data on IE8 and IE9 browser, but the couldn't display some special characters (eg. é)

In my webpage, I have explicitly declare 'UTF-8' encoding.

For my tomcat webserver, the server.xml 

<Connector port="8080" protocol="HTTP/1.1" 
           connectionTimeout="20000" 
           redirectPort="8443" URIEncoding="UTF-8" useBodyEncodingForURI="true"/>

I read some other questions in stackflow, they mentioned to also ensure the database connection is using 'UTF-8' too.

  <Resource name="jdbc/AppDB" 
        auth="Container"
        type="javax.sql.DataSource"
        maxActive="20" maxIdle="10" maxWait="10000"
        username="foo"
        password="bar"
        driverClassName="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost:3306/      ID_development?useEncoding=true&amp;characterEncoding=UTF-8"
    />

The solution given is for mysql. How can i set the encoding if im using oracleDriver?

<Resource name="jdbc/AppDB"
       auth="Container"
       type="javax.sql.DataSource"
       driverClassName="oracle.jdbc.OracleDriver"
       url="jdbc:oracle:thin:@127.0.0.1:1521:ora11"
       username="foo"
       password="bar"
       maxActive="20"
       maxIdle="1000"
       maxWait="-1" />

Please review this answer. Regardless of fact that it's focused on SQL Developer, it contains information about tuning JDBC driver and points out how to properly handle unicode character types in Oracle.

Update
Troubles with displaying characters on the client may be caused by wrong NLS_LANG settings on the database client (Tomcat in your case). For thin JDBC driver NLS_LANG value derived from java locale settings.
For possible variants you can look through the answers on this question and check Oracle documentation.
If a real source of the problem lies to character set of Oracle database connection, then there are only two possible end points to check: NLS_LANG and oracle.jdbc.defaultNChar . So you need to examine if both set properly to figure out what is happened.

  • Thank you @ThinkJet. The data is stored in the dB successfully, i'm encountering some displaying issue. And i do not have the permission to edit the dB, only the configuration in the web server (tomcat) – jj pan Aug 28 '13 at 01:30
  • Thank you @ThinkJet. I will use your suggestion to carry on the investigation and update with my finding. – jj pan Aug 29 '13 at 05:44
