Java Question

Cannot find the declaration of element 'ehcache'

I am implementing url caching in my web application. I have error in ehcache.xml file while run time. I am using spring 2.5 jar file.

ehcache.xml

<?xml version="1.0" encoding="UTF-8"?>

<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="ehcache.xsd" updateCheck="false"
monitoring="autodetect" dynamicConfig="true" maxBytesLocalOnHeap="2m"
maxBytesLocalOffHeap="2m" maxBytesLocalDisk="2m">


<defaultCache eternal="false" maxElementsInMemory="1000"
overflowToDisk="false" diskPersistent="false" timeToIdleSeconds="0"
timeToLiveSeconds="600" memoryStoreEvictionPolicy="LRU" />

<cache name="videoItemsCache" eternal="false"
maxElementsInMemory="1000" timeToIdleSeconds="1200" timeToLiveSeconds="1200"
overflowToDisk="false" diskPersistent="false"
memoryStoreEvictionPolicy="LRU" />

</ehcache>


Error is :

ERROR: VideoClubPortal 27-Sep-2012 11:53 context.ContextLoader Context initialization failed

Try something like this, this I am using in my project

applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>

</beans>

ehcache.xml

<ehcache>
