HttpSession class not found - maven

Question

I am building a project using groovy on grails 2.3.7. Rather that using the default grails plugins I want to configure the plugins as maven dependencies.
I also want to use jetty server instead of tomcat server and mongodb instead of the regular relational databases.
After creating the project I executed 'grails create-pom' to create the pom.xml file for the project.
I have added the following changes to the pom.xml.
Removed the dependency for hibernate and added the following dependency for mongodb
<dependency>
<groupId>org.grails.plugins</groupId>
<artifactId>mongodb</artifactId>
<version>3.0.1</version>
<scope>compile</scope>
<type>zip</type>
</dependency>
Removed the default plugin for tomcat and added the following plugin for jetty.
<dependency>
<groupId>org.grails.plugins</groupId>
<artifactId>jetty</artifactId>
<version>3.0.0</version>
<scope>compile</scope>
<type>zip</type>
</dependency>
I have also configured the repository for grails plugins.
While executing the code I get the following error.

Can anyone please tell me, what plugin I am missing or is there some thing I have configured incorrectly.

Answer 1

Add this to you pom.xml and see if it helps:-
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.0.1</version>
</dependency>
