Hi,
the problem is located in the creation of your "toolChooserLogic" bean.
Your class have a constructor, as you stated, but you want to create the
bean with no arguments, but setting the value for the
"xlinkServiceManager"through a setter. The correct construction of the
"toolChooserLogic" bean would look like this:
<bean id="toolChooserLogic" class="org.openengsb.ui.admin.xlink.ToolChooserLogicImpl">
<argument ref="xlinkServiceManager" />
</bean>
Then it should work :-)
Kind regards
Felix
