Could not get service from ref [javax.servlet.Servlet, javax.servlet.ServletConfig, java.io.Serializable]

[jond1978]

Hi,

While deploying our  application we are getting a WARN which says:

*WARN* [FelixFrameworkWiring] org.apache.sling.servlets.resolver [org.apache.sling.servlets.resolver.SlingServletResolver(593)] Could not get service from ref [javax.servlet.Servlet, javax.servlet.ServletConfig, java.io.Serializable]

Is this an expected behavior from OSGi bundles (Services may appear/disappear at any time).
Any pointers to solve this issue would be helpful.

Thanks

In AEM - services do not randomly appear and disappear. Are you seeing any strange behaviour in your application. Is your servlet working properly?

Hi jond1978

Agreeing with Scoots post, Service do not behave randomly.

Just for the reference, i would like you to go through the below mentioned article and gauge if you can find some ambiguity in the way you are doing the OSGi deployment. 

It is covering creation of OSGi service and how to deploy it.

I hope this would help you.

Thanks and Regards
