hi

i am creating an jsf liferay faces project.i wana use the dependency:
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>3.0.1</version>
<scope>provided</scope>
</dependency>
i can compile it wihtout errors but when i try to deploy it on liferay server then i get this error:
java.lang.classcastexception: class javax.faces.webapp.facesservlet

so how can i use the version 3.0.1 of that javax.servlet?
