Hi all,
we have build a webapp based on cocoon 2.2. Everything is working fine
if a single person is using the app, but as soon as we have concurrent
user the code fails with NPE in different lines of the code.
My questions are:
Every pipeline is thread safe, right?
The mounts to the different servlet (blocks) is synchronized, right?
Is there a connection timeout for inner block communications?
The architecture is as follow:
main webapp - mounts dispatcher sitemap (from block)
Main match:
<map:match pattern="**.html">
<map:generate src="lm://resolve.structurer.{1}" type="jx">
<map:parameter name="lenient-xpath" value="true"/>
<map:parameter name="getRequest" value="{1}"/>
<map:parameter name="contextPath"
value="{request:contextPath}"/>
<map:parameter name="getRequestExtension" value="html"/>
</map:generate>
<map:transform type="dispatcher">
<map:parameter name="cacheKey" value="{0}"/>
<map:parameter name="validityFile"
value="lm://resolve.structurer.{1}"/>
<map:parameter name="request" value="{1}"/>
<map:parameter name="type" value="html"/>
<map:parameter name="hooksTransformer"
value="lm://hooks-to-html.xsl"/>
</map:transform>
<map:transform src="lm://namespace-stripped"/>
<map:transform src="lm://strip-dispatcher-remains-html.xsl"/>
<map:serialize type="xhtml"/>
</map:match>
Have you made sure that your dispatcher transformer is configured correctly? If
it is *not* threadsafe, you have to use the "prototype" scope. Otherwise you can
use the "singleton" scope (which is actually the default!).
This is what I always thought and how it is in 2.1 and the old 2.2.
version of cocoon that forrest is using.
<bean id="dispatcher"
name="org.apache.cocoon.transformation.Transformer/dispatcher"
class="org.apache.forrest.dispatcher.transformation.DispatcherTransformer">
<property name="manager"
ref="org.apache.avalon.framework.service.ServiceManager"/>
</bean>
Just to be clear, if you configure you transformer like this, it has to be
threadsafe.
