JSP and Forms: if a field is empty

[Atrisa Milani]

Hi. I have the following code that gets the input names and their values from a form that is to be sent to my email. This is working fine.

  Enumeration paramNames = request.getParameterNames();
     while(paramNames.hasMoreElements()) {
       String paramName = (String) paramNames.nextElement();
       String paramValue = request.getParameter(paramName);
       message.println(paramName + ": " + paramValue);
       
      }

Then, when submitting the form, I want to leave out the fields that are empty, so I added an IF statement to the above:

  Enumeration paramNames = request.getParameterNames();
     while(paramNames.hasMoreElements()) {
       String paramName = (String) paramNames.nextElement();
       String paramValue = request.getParameter(paramName);
       if (paramValue != null) {
       message.println(paramName + ": " + paramValue);
}
       
      }

But the IF loop doesn't work and don't know why. I appreciate if anyone could help me with this.

Thanks in advance

Go it.

if (request.getParameter(paramName) != null && 
               request.getParameter(paramName) != "") {
       message.println(paramName + ": " + paramValue);
       }

One thing though: after this, the email goes to the spam folder rather then my inbox. I guess it is because I am testing and sending so many emails frequently and could be some security settings. When I try a new sender email then it goes to my inbox. Anyway, if any of you has a better explanation, please share it with me.
