Hi,
(anyone with any ideas about this...thanks in advance) /regards Peter
I'm having trouble getting a container to classload an artifact (a jar file) needed by a component declared within the container directive, se my kernel.xml snippet below. The "hello" component impl.class is in the cappuccino-1.0.0.jar and is internally using the class org.apache.avalon.framework.logger.Logger. Thus the dependcy to the avalon-framework-api-4.2.0.jar
If I remove all reference to the Logger in the java source for the HelloComponent everything is working properly, with a full lifecycle run by the merlin kernel, but trying to use the Logger it fails.
The avalon-framework-api-4.2.0.jar file is located in the local maven repository, the directory /home/petje/.maven/repository/avalon-framework/jars
I also tried using the fileset directive with this directory explicitly set with the same malfunctional result.
<?xml version="1.0" encoding="ISO-8859-1"?> <kernel>
<repository>
<hosts>
<host path="http://www.dpml.net/"/>
<host path="http://www.ibiblio.org/maven/"/>
</hosts>
</repository><container name="gonzo">
<classloader>
<classpath>
<fileset dir="/home/petje/cappuccino/target">
<include name="cappuccino-1.0.0.jar" />
</fileset>
<repository>
<resource id="avalon-framework:avalon-framework-api" version="4.2.0"/>
</repository>
</classpath>
</classloader>
<component name="hello" class="com.euronetics.cappuccino.HelloComponent"/>
</container>
</kernel>
This is the debug log...(look for the [WARN] statement)
