Encoding JSP Pages globally with specific encoding (Servlet 2.4 onwards)

if you are using servlet 2.4 and jsp 2.0

you can use the following special config in web.xml:

from http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd and http://java.sun.com/xml/ns/j2ee/jsp_2_0.xsd

<jsp-config>
<jsp-property-group>
<display-name>Setup default encoding</display-name>
<url-pattern>*.jsp</url-pattern>
<page-encoding>ISO8859-1</page-encoding>
</jsp-property-group>
</jsp-config>
