We are using richfaces integrated with spring running on weblogic server.

Sometimes when we login to the application we get the following error:

ERROR BaseXMLFilter : Exception in the filter chain
javax.servlet.ServletException: Resources framework is not initialised, check web.xml for Filter configuration


The following is the filter configuration in web.xml

Code:
<filter>
		<display-name>Ajax4jsf Filter</display-name>
		<filter-name>ajax4jsf</filter-name>
		<filter-class>org.ajax4jsf.Filter</filter-class>
		<init-param>
			<param-name>createTempFiles</param-name>
			<param-value>true</param-value>
		</init-param>
		<init-param>
			<param-name>maxRequestSize</param-name>
			<param-value>100000</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>ajax4jsf</filter-name>
		<servlet-name>Faces Servlet</servlet-name>
		<dispatcher>FORWARD</dispatcher>
		<dispatcher>REQUEST</dispatcher>
		<dispatcher>INCLUDE</dispatcher>
		<dispatcher>ERROR</dispatcher>
	</filter-mapping>
Help me out.

Thanks in advance
