"Sniffers with type [connector] and type [ejb] should not claim…" And Solution

The error:

"java.lang.IllegalArgumentException: Sniffers with type [connector] and type [ejb] should not claim the archive at the same time. Please check the packaging of your archive"

happens, when GlassFish doesn't know how to interpret a content of a deployment archive. The error is usually caused by wrong packaging of your archive.

I usually forget to set the scope (see bold tag below) in the pom.xml of the glasssh-embedded-all (needed because of Maven / Java EE 6 trouble), what causes the deployment of the whole embedded GlassFish with the WAR and the error above.


I would provide a error message like: "Deployment of servers inside WARs is unusual in Java EE 6 context and may result in not portable applications :-)".

Perfect solution, thanks a lot! :)

Thank you! I had updated my pom to pull the latest version of a glassfish jar rather than use the one on my machine and of course left out the "provided". Your blog has been very useful to me as I try to catch up with what Java has been up for the last 10 years....
