Jackson throwing nosuchmethod error while

I have following class which i am returning from spring rest server

public class Message {
    private String name;
    private String text;

    public Message(String name, String text) {
        this.name = name;
        this.text = text;
    }

    public String getName() {
        return name;
    }

    public String getText() {
        return text;
    }
}

And I am getting following error when i try to access the api

g.springframework.web.util.NestedServletException: Handler processing failed; nested exception is java.lang.NoSuchMethodError: com.fasterxml.jackson.databind.type.TypeFactory.constructType(Ljava/lang/reflect/Type;Ljava/lang/Class;)Lcom/fasterxml/jackson/databind/JavaType;

    javax.servlet.http.HttpServlet.service(HttpServlet.java:729)
    org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52)

here is my jackson mapping tree via mvn dependency:tree | grep jackson

[INFO] +- org.codehaus.jackson:jackson-mapper-asl:jar:1.9.9:compile
[INFO] |  \- org.codehaus.jackson:jackson-core-asl:jar:1.9.9:compile
[INFO] \- com.fasterxml.jackson.core:jackson-databind:jar:2.7.0:compile
[INFO]    +- com.fasterxml.jackson.core:jackson-annotations:jar:2.7.0:compile
[INFO]    \- com.fasterxml.jackson.core:jackson-core:jar:2.7.0:compile

and here is my actual jackson dependency in pom.xml

<dependency>
    <groupId>org.codehaus.jackson</groupId>
    <artifactId>jackson-mapper-asl</artifactId>
    <version>1.9.9</version>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.7.0</version>
</dependency>

I have tried including latest version of both libraries. I am not sure what i am missing here.

Which Spring version are you using? Check out the library requirements for Spring on the Spring wiki.

If you're using Spring 4+, you don't need org.codehaus dependencies.

Now there are some issues with Jackson 2.7 - this version will be supported in Spring 4.3 (see SPR-13728 and SPR-13483). In the meantime, you should stick to Jackson 2.6+.
