Hi all,
I have a system where i have a servlet generating xml from some ejb's
I use cocoon to apply xsl to the xml and produce the various outputs.
I have tried two methods, and both works fine, but i need to cache the
result ans the servlet is QUITE slow and rarely changes its output.
i have tried this:
<map:match pattern="test">
<map:generate src="http://server/genXML"/>
<map:transform src="stylesheets/transform.xsl"/>
<map:serialize/>
</map:match>
and this
<map:match pattern="readXML">
<map:read src="http://server/genXML"; mime-type="text/xml"/>
</map:match>
<map:match pattern="test2">
<map:generate src="readXML"/>
<map:transform src="stylesheets/transform.xsl"/>
<map:serialize/>
</map:match>
as stated it all work fine but is not cached as far as i can tell.
Is there a way for me to monitor the cache. but im quite sure it is not
cached as it is still very slow.
I have striped my sitemap.xmap to the minimum and is deploying the
application with all the libs from cocon. so im not as such using
cocoon.war
I guess my problem is that i need something more in either sitemap og
xconf
sitemap:
<map:components>
<map:generators default="file">
<map:generator name="file"
src="org.apache.cocoon.generation.FileGenerator"
pool-max="32" pool-min="16" pool-grow="4"/>
</map:generators>
<map:transformers default="xslt">
<map:transformer name="xslt"
src="org.apache.cocoon.transformation.TraxTransformer"
pool-max="32" pool-min="16" pool-grow="4">
<use-store>true</use-store>
<use-request-parameters>false</use-request-parameters>
<use-browser-capabilities-db>false</use-browser-capabilities-db>
</map:transformer>
</map:transformers>
<map:readers default="resource">
<map:reader name="resource"
src="org.apache.cocoon.reading.ResourceReader"/>
</map:readers>
<map:serializers default="html">
<map:serializer name="html"
mime-type="text/html"
src="org.apache.cocoon.serialization.HTMLSerializer"/>
</map:serializer>
</map:serializers>
and the pipline with the above lines.
in cocoon.xconf i have:
<stream-pipeline
class="org.apache.cocoon.components.pipeline.CachingStreamPipeline"
pool-max="32" pool-min="16" pool-grow="4"/>
<stream-cache
class="org.apache.cocoon.components.store.MRUMemoryStore">
<parameter name="freememory" value="1000000"/>
<parameter name="heapsize" value="60000000"/>
<parameter name="cleanupthreadinterval" value="10"/>
<parameter name="maxobjects" value="100"/>
<parameter name="usecleanupthread" value="true"/>
<parameter name="threadpriority" value="5"/>
<parameter name="filesystem" value="true"/>
</stream-cache>
<event-pipeline
class="org.apache.cocoon.components.pipeline.CachingEventPipeline"
pool-max="32" pool-min="16" pool-grow="4"/>
<event-cache
class="org.apache.cocoon.components.store.MRUMemoryStore">
<parameter name="freememory" value="1000000"/>
<parameter name="heapsize" value="60000000"/>
<parameter name="cleanupthreadinterval" value="10"/>
<parameter name="maxobjects" value="100"/>
<parameter name="usecleanupthread" value="true"/>
<parameter name="threadpriority" value="5"/>
<parameter name="filesystem" value="true"/>
</event-cache>
I have read the docs on caching, an i think what i do is right, but i
dont quite understand the xmlserilization part, but i have tried to
include
<xml-serializer
class="org.apache.cocoon.components.sax.XMLByteStreamCompiler"/>
<xml-deserializer
class="org.apache.cocoon.components.sax.XMLByteStreamInterpreter"/>
but to no avail.
The bedst would be if it was cached at the html setilization step, but
at xml generation step would be ok. I have also tried to generate the
xml with generate / xml seriliaze instead of read.
Thanks alot for any inputs. Thanks.
I really hope to solve this, as the system cant go live till i have
solved the performance problem.
thanks again
Jesper
