Tomcat Java Eclipse ENCODING drive me crazy

This is what I update.
Under Tomcat 7 folder/conf/server.xml
Find 8080 word. This will be like:
URIEncoding="UTF-8"
/>
Add URIEncoding="UTF-8" if the encoding needs to be set UTF-8. Or you can change to any other fix charset.

Remember set same encoding on JSP file


Now...... Another problem happened. Same issue when using Eclipse to start Tomcat.
Solution: Expand "Server" on the Project Explorer (left side). There is anotehr Server.xml. The physical location should hiding under "workspace" folder. Change same URIEncoding="UTF-8".

NOW..... Database make the same issue.... The "words" select from DB and the data from web page is not equal........
