Jsp Servlet Exception

I saw some kind of similar answer to this question, perhaps, but I feel that my situation is different. I am developing a spring MVC application that has been working fine so far, that is, I included hadoop api in my project when I included hadoop, this exception started when I try to open the dashboard start page that worked earlier:

java.lang.AbstractMethodError: javax.servlet.jsp.JspFactory.getJspApplicationContext(Ljavax/servlet/ 
ServletContext;)Ljavax/servlet/jsp/JspApplicationContext;
 org.apache.jsp.ServerInfo_jsp._jspInit(ServerInfo_jsp.java:63)
 org.apache.jasper.runtime.HttpJspBase.init(HttpJspBase.java:52)
 org.apache.jasper.servlet.JspServletWrapper.getServlet(JspServletWrapper.java:158)
 org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:328)
 org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:336)
 org.apache.jasper.servlet.JspServlet.service(JspServlet.java:265)
 javax.servlet.http.HttpServlet.service(HttpServlet.java:803)
 org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:9

Here's what my hadoop dependency looks like:

<dependency>
            <groupId>org.apache.hadoop</groupId>
            <artifactId>hadoop-client</artifactId>
            <version>0.23.1-mr1-cdh4.0.0b2</version>
        </dependency>
        <dependency>
            <groupId>org.apache.hadoop</groupId>
            <artifactId>hadoop-core</artifactId>
            <version>0.23.1-mr1-cdh4.0.0b2</version>
            <exclusions>
                <exclusion>
                    <groupId>org.mortbay.jetty</groupId>
                    <artifactId>jetty</artifactId>
                </exclusion>
                <exclusion>
                    <groupId>javax.servlet</groupId>
                    <artifactId>servlet-api</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

As soon as I add this to my application, it can no longer be used and, naturally, without these dependencies everything works very smoothly. What am I missing here?
