issue with configuration policy=require and with factory components
-------------------------------------------------------------------
Key: FELIX-1922
URL: https://issues.apache.org/jira/browse/FELIX-1922
Project: Felix
Issue Type: Bug
Components: Declarative Services (SCR)
Affects Versions: scr-1.2.0
Environment: linux fc10, jdk1.5, jdk.1.6
Reporter: Pierre De Rop
Priority: Minor
This issue is related to the following dev post: ->
http://www.mail-archive.com/[email protected]/msg14167.html
There are two components that comes into play:
1) The first one (EnglishDictionary) has a configuration-policy="require"
parameter and a factory="true" parameter:
<?xml version='1.0' encoding='utf-8'?>
<component name='EnglishDictionary'
xmlns='http://www.osgi.org/xmlns/scr/v1.1.0' factory='true'
configuration-policy='require' modified='updated'>
<implementation
class='com.alcatel_lucent.samples.scr.dictionary.english.EnglishDictionary'/>
<service>
<provide
interface='com.alcatel_lucent.samples.scr.dictionary.DictionaryService'/>
</service>
</component>
The EnglishDictionary parameter has actually a CM Configuration which is
required before activation: that is why it uses configuration-policy='require'.
2) The second one (EnglishDictionaryFactory) is a factory component that is
meant to instantiate the EnglishDictionary component.:
<?xml version='1.0' encoding='utf-8'?>
<component name='EnglishDictionaryFactory'>
<implementation
class='com.alcatel_lucent.samples.scr.dictionary.english.EnglishDictionaryFactory'/>
<reference name='bind' interface='org.osgi.service.component.ComponentFactory'
bind='bind' unbind='unbind' target='(component.name=EnglishDictionary)'/>
</component>
The issue takes place when the EnglishDictionaryFactory component tries to
instantiate the EnglishDictionary like this:
class EnglishDictionaryFactory {
public void bind(ComponentFactory factory) {
factory.newInstance(new Hashtable());
}
}
-> The newInstance raises the following exception:
