I went to javasoft site and it seems to me that introspection its more used
in Beans. Can I also use that in servlets? How?

Subject: Re: Null Values in Servlets
Use introspection to capture all valid .getParameters(), then the bean
associated to the form can simply check for null values when assigning them
Ie...
public void setUserName(String username) {
this.username = (( username==null)? "" : username );
}
This should alleviate the null value problems. If you are not familiar with
introspection I would recommend reading about it on the javasoft site. It
would help if you were implementing your JSP/Servlets using the Model 2
architecture as well.
Hope this helps... Dean

Importance: High
This data comes from a form and its pass to the servlet when we
press the submit button, so I don't have any type of control over that. If
the user don't write nothing, the field will have the null value in the
servlet.

One option is to use "" instead of sending empty values. Invariably, from
what I have noticed, these are 'null' values. If not set, then this causes
an error.
I hope this helps,
Girish
