Issues adding hibernate-ehcache to Eclipse project

[Jason Trinity]

Hello everyone,

I am trying to add 2nd level caching to an existing Eclipse project. It is using hibernate 3.6.0.final, so I added hibernate-ehcache-3.6.0.final, and ehcache-core-1.5.0. I added to my hibernateProperties the following lines,

<prop key="hibernate.cache.region.factory_class">net.sf.ehcache.hibernate.EhCacheRegionFactory</prop>
<prop key="hibernate.cache.provider_configuration">config/ehcache.xml</prop>
<prop key="hibernate.cache.use_second_level_cache">true</prop>
<prop key="hibernate.cache.use_query_cache">true</prop>

But I get an exception when I run the code

java.lang.ClassNotFoundException: net.sf.ehcache.hibernate.EhCacheRegionFactory cannot be found

I've tried multiple things,

Tried upgrading to:
hibernate 3.6.10.final, hibernate-ehcache-3.6.10.final, and ehcache-core-2.4.3
, but I just got the same error.

I also tried changing

<prop key="hibernate.cache.region.factory_class">net.sf.ehcache.hibernate.EhCacheRegionFactory</prop>

to

<prop key="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</prop>

But I got the error: java.lang.ClassNotFoundException: net.sf.ehcache.CacheException cannot be found

I also tried

<prop key="hibernate.cache.provider_class">net.sf.ehcache.hibernate.EhCacheProvider</prop>

but go an error java.lang.ClassNotFoundException: net.sf.ehcache.hibernate.EhCacheProvider cannot be found


I'm using Windows 7, java 1.6, and Eclipse Kepler
Any clues would be appreciated.

Thanks.

Hi Jason, welcome to the Ranch!

Two questions:

Which jar is net.sf.ehcache.hibernate.EhCacheRegionFactory in?

And is that jar in your Eclipse project's build path?

[Jason Trinity]

Paul,

net.sf.ehcache.hibernate.EhCacheRegionFactory is in ehcache-core-1.5.0.jar.

This is what my .classpath looks like

This is just frustrating. I tried switching to OSCache to see if I had any luck with it, but now I get

java.lang.ClassNotFoundException: com.opensymphony.oscache.base.Config cannot be found

I hate Eclipse, but sadly this application depends on it.

[Jason Trinity]

I upgraded my libraries to hibernate-ehcache-3.6.10.Final.jar, hibernate-core-3.6.10.Final.jar, and ehcache-2.4.3.jar and I still get the same error. It looks like Eclipse is not finding the class.

[Paul Clapham]

This seems to be a problem with Eclipse so I've moved the post into the IDEs forum, maybe more people will see it there.

Could you post the whole stack trace including the single line you posted already? That would provide more context for what's running and what's calling what.

[Jason Trinity]

Thank you. This is the error I am getting.
