[midPoint] Problem adding an ICF connector - Error creating connector instace: The classes (JAR) of connector: ... (OID:...) were not found by the ICF framework

[Radovan Semancik]

Hi,

This sound like an interesting problem.

ICF is a tricky thing. It is using its own classloaders. Therefore the 
things may be slightly different that it may seem at the first sight. 
Firstly please make sure that the you are using the correct annotation 
in the connector class. Something like this:

@ConnectorClass(displayNameKey = "UI_CONNECTOR_NAME", configurationClass 
= DummyConfiguration.class)
public class DummyConnector implements Connector, ......

The archetype is maintained by the OpenICF project and I'm not 100% sure 
that it works correctly. We actually do not use it and we usually create 
the connector structure manually. Therefore it is possible that the 
archetype does not create a correct code. It is better to double-check 
the generated code.

Secondly please make sure that the JAR classes of the connector are 
placed in the <midpoint.home>/icf-connectors/
Simply placing the JAR files on the classpath is not enought. ICF 
classloaders in midPoint are set up to look at this specific location.

Also please make sure that the JAR contains a correct MANIFEST.MF file. 
It should look like this:
