Need help setting up cacheable annotation

Everything seems to be ok, but nothing gets cached. I have followed the other threads that have discussed this to no avail. there has got to be something I am missing.

Here is my configuration:

<ehcache:config configLocation="classpath:/ehcache.xml" serializableFactory="XSTREAM" />

<ehcache:annotations>
<ehcache:caching id="licenseAssetCacheModel" cacheName="licenseAssetCache"/>
<ehcache:flushing id="licenseAssetFlushModel" cacheNames="licenseAssetCache"/>
</ehcache:annotations>

I have this dependency setup in my pom.xml

<dependency>
<groupId>org.springmodules</groupId>
<artifactId>spring-modules-cache</artifactId>
<version>0.9</version>
</dependency>
<dependency>
<groupId>net.sf.ehcache</groupId>
<artifactId>ehcache</artifactId>
<version>1.5.0</version>
</dependency>

Everything seems fine at startup:

I have annotated the interface as such:

Cacheable(modelId = "licenseAssetCacheModel")
LicenseAsset getLicenseAsset(Long assetId);

Then, nothing. no caching. what gives.

anybody. thanks.

check out previous postings...

try to remember using

Code:

code tags..

for posting code...

within Spring-Modules search for RShelley post with the title "Declarative Caching" (I can't post links yet). It has a lot of useful information on setting up.

tip -> make sure the annotated part is being done in the interfaces, not the implementation classes.

Hey josh, thanks for the tips, I read those in the researching my problems. I finally got it working but I'm not proof positive why. The most obvious answer is that I was suffering my jar issues on the classpath. In the process of getting the 0.8a jar working I must of cleared a discrepancy. I then went and put back the 0.9 jar and all was fine.

Thanks,

zach

Hey,

How did you get it work?

If you are trying to use Spring 3.0, there is a new project listed at the end of this thread that uses annotations for caching. I haven't had time to try it out yet, but it might be worth looking into.

I have already configured it to load cache file after servlet configuration. Also I am using spring aop 3.0 and with that I was getting "java.lang.ClassNotFoundException: org.springframework.metadata.Attributes" as all are getting on other threads. So I had included spring 2.5.6-jar and after that it is not throwing exception but caching is also not happening.
