Hello Vitaly:
Sorry for the belated reply, I was out of office for a few days.
See below. I put this in a jsp file and put it right under /jetspeed at
this point.
Also, if you don't want to include Jetspeed library, you may enable the
"shared" in /assembly/cache.xml file as:
<bean id="cacheManager"
class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
<!-- get it through the class path
<property name="configLocation"
value="${applicationRoot}/WEB-INF/conf/ehcache.xml"/>
-->
<!-- <property name="shared" value="true" /> -->
</bean>
This way, you don't need to use the jetspeed API and you can use
//CacheManager ehCacheManager=CacheManager.getInstance(); as commented
out in the following... Either way will work...
