JBoss does not have a Servlet implementation

[cqql]

Hi,

I am using org.jboss.resteasy.plugins.guice.GuiceResteasyBootstrapServletContextListener as a servlet listener and have also set resteasy.scan.resources to true. This leads to the following error:

13:44:28,824 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/project]] (MSC service thread 1-4) Exception sending context initialized event to listener instance of class org.jboss.resteasy.plugins.guice.GuiceResteasyBootstrapServletContextListener: java.lang.NoClassDefFoundError: javax/servlet/ServletContext

Why is there no class definition for javax.servlet.ServletContext? My maven dependencies do not cover it so it should find the implementation which JBoss must have.

I am using JBoss 7.0.2.

Thanks in advance,

The missing class should be in modules/javax/servlet/api/main/jboss-servlet-api_3.0_spec-1.0.0.Final.jar

[cqql]

But why is it not loaded automatically?

[peterj]

You verified that the JAR file exists, and that the file is not corrupted, and that it contains that class?

Also, which download are you using? The Web Profile or Everything? And how are you starting the app server?

[cqql]

I am using Everything. And yes, I have verified that the ServletContext class exists in that file.

I start the app server with "./bin/standalone.sh"

[peterj]

I suspect a classloader issue/ Try adding "-verbose:class" to one of the JAVA_OPTS settings in standalone.conf, then redirect stdout and stderr to a file when starting the app server. The -verbose:class  option prints the JAR file for each class laoded, look for JAR files that are not loaded from the "modules" directory. Especially look for where GuiceResteasyBootstrapServletContextListener is loaded.
