Absent Code attribute in method that is not native or abstract in class file javax/servlet/ServletException

I am planning to use Java servlets in my application. I included the following in my project's POM.xml file to load Java servlet 3.0 implementation jar.

<dependency>
    <groupId>org.glassfish</groupId>
    <artifactId>javax.servlet</artifactId>
    <version>3.2-b05</version>
</dependency> 

The project compiles fine. However, when I run it, I get the following error:

java.lang.ClassFormatError: Absent Code attribute in method that is not native or abstract in class file javax/servlet/ServletException

I searched for it here and found some good answers.

I figured out from them that this error happens when we include the JAR which contains only interfaces defined by servlet API and not the actual implementation. So, I checked that the glassfish jar I am using is just interfaces or it contains implementation too. I found that it is an implementation and not just interfaces.

So now, I am wondering why I am getting this error at runtime. Anyone?

UPDATE:

Just now, I found out that it was a blatant error from my side (I was adding the jar to one project, while, was running an altogether different project!). I am sorry for this. Adding the glassfish servlet implementation DOES solve the issue.

Thanks, Sandeep
