Instantiating Beans on Tomcat

I am trying to instantiate a very simple bean on Tomcat in a JSP using the
directive...

<jsp:useBean id="sessionBean" scope="session" class="InfoBean" />

Everytime I try to run it, I get the following exception...

javax.servlet.ServletException:  Cannot create bean of class InfoBean

Any idea why this is happening, my java code doesn't have anything in it
yet, I just want to test it so that the bean will work, here is what I have
in the java in case I have that wrong...



public class InfoBean {
  private String sample = "Sample";

  public InfoBean() {
			  }//end constructor


  public String getSample() {
    return sample;
  }
  public void setSample(String newSample) {
    sample = newSample;
  }
}

Any ideas on what I'm doing wrong, could this be due to some session
settings in Tomcat?

Thanks!

Brandon

Yeah, there must be something I'm missing, maybe there's some setting in
tomcat which allows me to use beans or something, but I can't find where
that would be.

I was getting those but it was because my bean didn't have a constructor
that took no args but it looks like yours does...

Not sure...
