Sorry, I've forgotten to activate logging, here an extendet version of tomcats
output, maybe now
you are able to see what is happening:
<snip/>
[org.apache.cocoon.el.impl.objectmodel.ObjectModelImpl] for bean with name
'scopedTarget.org.apache.cocoon.el.objectmodel.ObjectModel' defined in URL
[jar:file:/home/pepemuck/_opt/tomcat55/webapps/isacWebApp/WEB-INF/lib/cocoon-pipeline-impl-1.0.0-RC2.jar!/META-INF/cocoon/spring/ObjectModel.xml]:
problem with class file or dependent class; nested exception is
java.lang.NoClassDefFoundError:
org/apache/commons/collections/map/AbstractMapDecorator Caused by:
java.lang.NoClassDefFoundError: org/apache/commons/collections/map/AbstractMapDecorator
Ok. Now everything is clear.
Class org.apache.cocoon.el.impl.objectmodel.ObjectModelImpl comes from cocoon-expression-language
module, its dependencies can be found here:
http://cocoon.apache.org/2.2/core-modules/expression-language-impl/1.0/dependencies.html
As you can see, EL module depends on commons-collections:3.2, now let's take a look at your
dependencies listings:
myDomainBlock:
[INFO] commons-collections:commons-collections:jar:2.1.1:compile
isac:
[INFO] commons-collections:commons-collections:jar:3.2:compile
isacWebApp:
[INFO] commons-collections:commons-collections:jar:2.1.1:compile
As you see, wrong version (coming from myDomain) lands in your webapp and that's why it breaks. I
think that Patrick it's crucial now for you to understand how transitive dependencies work in Maven
in order to effectively resolve such problems.
You sould study [1][2] and then decide to use exclusion mechanism or direct dependency specification
(so right version is being pulled).
