"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.


<dependencies>
    <dependency>
        <groupId>org.glassfish.extras</groupId>
        <artifactId>glassfish-embedded-all</artifactId>
        <version>3.1.1</version>
       <scope>provided</scope>
    </dependency>
</dependencies>

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 :-)".
