hi stephen,
the "bin/BLOCK-INF/block.xml" looks like:
<container name='econ'>
<classloader>
<classpath>
<repository>
<resource id="avalon-framework:avalon-framework-impl" version="4.1.5"/>
</repository>
</classpath>
</classloader>
<component name='hello' class='tutorial.impl.HelloComponent'/>
</container>
in HelloComponent.xinfo there is:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE type PUBLIC "-//AVALON/Type DTD Version 1.0//EN"
"http://avalon.apache.org/dtds/meta/type_1_1.dtd"; >
<type>
<info>
<name>hello</name>
<version>1.0.0</version>
<lifestyle>singleton</lifestyle>
<collection>hard</collection>
</info>
<dependencies>
<dependency key="random" type="tutorial.RandomGenerator" version="1.0.0"/>
<dependency type="tutorial.Identifiable"/>
</dependencies>
</type>
and the concole shows:
