Hello
I am using cacheable in my code . I am experiencing a issue while using it .
I have a method in ONE class which is cacheable , its working. After this class second gets the call , in which I have another method which is also cacheable, this method in the second class isnt working . I mean even though the @cacheable is there , the method code executes every time rather than picking from cache.
Does any body have experienced this kind of issue , please post.
Rest all , if you would put your thoughts , will be helpful.

"cacheName is not resolvable " . The cachable class contains key,value and condition only no variable like cacheName.

Currently I am using standalone ehcache i.e. with out TC but in future I will be using TC opensource.

@Cacheable(value = "attributes", key = "#p0")
public CacheableBean<Attribute> getCachedAttributes(String cacheKey, Connection connection) {

}

I am caching a POJO bean with above method.

Hello there,
I have used @ cacheable on a method which I have not kept synchronized , because on google code site http://code.google.com/p/ehcache-spring-annotations/wiki/UsingCacheable' target='_new' rel="nofollow"> http://code.google.com/p/ehcache-spring-annotations/wiki/UsingCacheable
of ehcache , in @cachable setting sections , its clearly written that its synchronized but actually its not. I have tested with two threads simultaneously accessing the @cachable method . Both threads enter the method instantly with out waiting.
Is there any setting to enable synchronization on @cachable annotation?

Sorry I coudnt get you Sir, I have tried the urls to search the answer , but dint get what I was looking for i.e. starting/stopping terracotta server programitically most probably thru java code.

.Currently I am starting/stopping the terracotta server using start-tc-server.bat script file only. But now I have a need where I haveto start the terracotta server on my webserver e.g. jboss/tomcat startup.

thanks for reply .currently I am starting/stopping the terracotta server using start-tc-server.bat script file only. But now I have a need where I haveto start the terracotta server on my webserver e.g. jboss/tomcat startup most prob ably through java code.

Hello there,
I am using terracotta-ehcache spring version in my app . Currently I have to start terracotta server using the batch file start-tc-server.bat and it works as expected.
Now I have a need to start the terracotta server through java code rather than a batch file . I am using jboss as app server and I need to start/stop the terra cotta server when jboss starts/stops. Is there any way to achieve this using spring or through java code?
Please post your inputs/experiences related to the same.
thanks in advance

Hello All,
I am new user of Ehcache . I am trying to use ehcache in my application. I have written
CacheManager cacheManager = CacheManager.getInstance(); in init method of my servlet. While loading the servlet I am seeing exception in logs. Its

However instead of servlet if I put the same statement in my JSP which gets called on user click , there is no exception and it works fine.
But I need to use the cache manager at start of my web app only i.e. in servlet.
If any one can put their valueable comments/experiences about the same , will be very helpful.
thanks
