JSP and Forms: if a field is empty

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.

Code:

---

  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:

Code:

---

  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.

Code:

---

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.
