  * Object Cache helps to improve the database performance.
  * OJB is able to use different Object Cache Implementations.
- * The default OJB Object Cache Implementation is fast, but has [http://db.apache.org/ojb/objectcache.html#Shipped%20cache%20implementations

+ * The default OJB Object Cache Implementation is fast, but has [http://db.apache.org/ojb/docu/guides/objectcache.html#ObjectCacheDefaultImpl

  * Since Cocoon 2.1.5 the default cache implementation is based on Apache JCS.
  * Apache JCS is a distributed caching system for server-side java applications. It is far
more powerful.

 ===  Let your servlet breathe calm ===
 My first attempt to setup this configuration failed because of a {{{OutOfMemoryError}}}.
The problem showed to be that the servlet does not had enough memory to run. ie: add this
lines in {{{catalina.sh}}}:
 
-{{{
-# Set Java Options
-JAVA_OPTS='-Xms32m -Xmx128m'
-if [ -r "$JAVA_OPTS"/bin/setenv.sh ]; then

 ===  Tell OJB to use JCS ===
 In your {{{OJB.properties}}} file, find the '''Object Cache''' section. Comment the line
where is {{{ObjectCacheDefaultImpl}}} and uncomment the line where is {{{ObjectCacheJCSPerClassImpl}}}.

 ===  Tell Cocoon that OJB will use JCS ===
 Cocoon is shipped with a default JCS configuration. Cocoon allow to define new cache regions
for JCS via {{{cocoon.xconf}}}. We need to configure the default region used by the JCS !ObjectCache
implementation for OJB. Search <store> and add this parameters:
 
-{{{
-<store logger="core.store">
-    <parameter name="maxobjects" value="10000"/>
-    <parameter name="use-cache-directory" value="true"/>
-    <parameter name="jcs.region.ojbDefault" value="DC"/>
-    <parameter name="jcs.region.ojbDefault.cacheattributes"
-               value="org.apache.jcs.engine.CompositeCacheAttributes"/>
-    <parameter name="jcs.region.ojbDefault.cacheattributes.MaxObjects" value="1000"/>
-    <parameter name="jcs.region.ojbDefault.cacheattributes.MemoryCacheName"
-               value="org.apache.jcs.engine.memory.lru.LRUMemoryCache"/>
-</store>
+{{{
+<store logger="core.store">
+    <parameter name="maxobjects" value="10000"/>
+    <parameter name="use-cache-directory" value="true"/>
+    <parameter name="jcs.region.ojbDefault" value="DC"/>
+    <parameter name="jcs.region.ojbDefault.cacheattributes"
+               value="org.apache.jcs.engine.CompositeCacheAttributes"/>
+    <parameter name="jcs.region.ojbDefault.cacheattributes.MaxObjects" value="1000"/>
+    <parameter name="jcs.region.ojbDefault.cacheattributes.MemoryCacheName"
+               value="org.apache.jcs.engine.memory.lru.LRUMemoryCache"/>
+</store>
 }}}
 
 The last 4 parameters (starting with '''jcs.region.ojbDefault''') define the cache region
that OJB will use.
