ApplicationContext refresh and Hibernate cache

[Jakob O.]

Hello community,

I wanted to reload the spring configuration from within my web-app and used:

ServletContext ctx = JsfContextUtils.getServletContext();
ConfigurableApplicationContext appCtx = (ConfigurableApplicationContext)
            		WebApplicationContextUtils.getRequiredWebApplicationContext(ctx);
appCtx.refresh();

Unfortunately the hibernate cache seems to not like it (I am using EHCache for second level caching btw.):

Caused by: java.lang.NullPointerException
	at org.hibernate.cache.impl.bridge.RegionFactoryCacheProviderBridge.nextTimestamp(RegionFactoryCacheProviderBridge.java:93)
	at org.hibernate.impl.SessionFactoryImpl.openSession(SessionFactoryImpl.java:637)
	at org.hibernate.impl.SessionFactoryImpl.openSession(SessionFactoryImpl.java:646)
	at org.springframework.orm.hibernate3.SessionFactoryUtils.doGetSession(SessionFactoryUtils.java:318)
	at org.springframework.orm.hibernate3.SessionFactoryUtils.getSession(SessionFactoryUtils.java:233)
	at org.springframework.orm.hibernate3.support.HibernateDaoSupport.getSession(HibernateDaoSupport.java:170)
	at org.springframework.orm.hibernate3.support.HibernateDaoSupport.getSession(HibernateDaoSupport.java:143)

Any hints on that one?

Thank you in advance

Jakob

Gentle bump. Should I probably rather ask in the "Data"-Forum than here?

Why do you think this is ApplicationContext related problem... Error you posted says a NullPointerException. Also posting complete error stack may help.

I have not seen you asking this question any where else, is this problem resolved?

Hi,

no I didn't solve the problem, but I didn't want to cross-post. I guess it's an application-context related problem since the application works fine until I try to refresh the context, which might be caused by not shutting down the second level cache cleanly and reinstantiating it when the session factory singleton is refreshed (destroyed and recreated).

Additionally I will turn on spring logging and add the output.

Regards

Jakob
