creating a filter in my spring mvc application using IDE

Question

I'm trying to create a filter, for some reason I am not seeing autocompletion when I create a class that implements a Filter.

When I type:

import javax.servlet

IDEA doesn't seem to pickup the namespace.

Is this a separate .jar that I have to setup in maven?

Update

My filter mappings look like:

<filter>

        <filter-name>performancefilter</filter-name>
        <filter-class>com.blah.core.filters.PerformanceFilter</filter-class>
    </filter>

    <filter-mapping>
        <filter-name>performancefilter</filter-name>
        <url-pattern>/</url-pattern>
    </filter-mapping>

Then you probably don't have the servlet-api defined as dependency in your pom.xml. Assuming you're using Servlet 2.5, your pom.xml should declare:

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>servlet-api</artifactId>
    <version>2.5</version>
    <scope>provided</scope>
</dependency>
