1. Create a cache in your service (in the components.xml) like so:

   Code Block
   xml xml
   <bean id="org.sakaiproject.user.api.UserDirectoryService.cache" class="org.springframework.cache.ehcache.EhCacheFactoryBean"> <property name="cacheManager"> <ref bean="org.sakaiproject.memory.api.MemoryService.cacheManager"/> </property> <property name="cacheName"> <value>org.sakaiproject.user.api.UserDirectoryService</value> </property> </bean>

2. Spring inject the cache into your service like so:

   Code Block
   xml xml
   <bean id="org.sakaiproject.user.api.UserDirectoryService" ... ... <property name="cache"> <ref bean="org.sakaiproject.user.api.UserDirectoryService.cache" /> </property> </bean>

3. Use the cache within your code:

   Code Block
   java java
   cache.get(key).getObjectValue(); cache.put(new Element(key,value)); cache.remove(key);

• NOTE This cache is not cluster wide and exists on one server only. You have to handle cluster wide expiring yourself.
