Ehcache and SLF4J error -

i new ehcache , slf4j .i using ehcache-2.6.6

i have used

slf4j-api-1.6.1 jar

slf4j-jdk14-1.6.1 jar

when extracted ehcache-2.6.6-distribution.tar these 2 jars in folder lib .

this ehcache.xml

when run program getting following output

though getting expected output there error in beginning saying :

i in slf4j-api version not match of binding error not error

i saw similar error here ehcache: simple program not working taking distributed cache. code took reference java/ehcache: simple example of use of ehcache 2.6.2

any please why getting error in beginning?

as warning says

to avoid warning consider using cachemanager factory methods create singleton cachemanager or specifying separate ehcache configuration (ehcache.xml) each cachemanager instance. 

the following line using singletonehcacheprovider may fix issue

<property name="hibernate.cache.provider_class">net.sf.ehcache.hibernate.singletonehcacheprovider</property>
