Hi, If you're using the felix web console, could you deploy: http://repo1.maven.org/maven2/org/apache/felix/org.apache.felix.ipojo.webco nsole/1.4.4/org.apache.felix.ipojo.webconsole-1.4.4.jar And check the state of the sampleServlet2 instance (before and after the issue). To get the state, in the web console, just go to the iPOJO Tab.
