I applied spring validation in my registration page .but the follwing error are shown in my server log of my app engine server.

 javax.servlet.UnavailableException: 
    org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException:
    Line 22 in XML  document from ServletContext resource 
    [/WEB-INF/spring/appServlet/servlet-context.xml] is invalid; 
    nested exception is org.xml.sax.SAXParseException;
    lineNumber: 22; columnNumber: 30;

</beans:beans>

Answer 1

Default XML namespace of your document is http://www.springframework.org/schema/mvc, therefore you should use namespace prefix for all elements from other namespaces, including elements from http://www.springframework.org/schema/beans namespace:

<beans:property name="validator">
    <beans:bean class="com.my.validation.UserValidator" />
</beans:property>

Alternatively, you can configure http://www.springframework.org/schema/beans as a default namespace:

xmlns = "http://www.springframework.org/schema/beans"

Obviously, in this case you’d need to use namespace prefix for elemetns from mvc namespace, if you have any.
