Hello,
This is killing me. I've got a form that posts to a servlet. I simply want
to get the form variables into a bean's properties.
I can find only one reference to what I'm trying to do here. it is a
formToBean() method from a FormUtils package, that some company sells.
Reading form variables into and out of javabean from a servlet has to be a
common activity. I can find heaps of info about using beans from JSP pages
(specifically about introspection), but I need to manipulate bean properties
from both Servlets and or JSPs. How do I do the introspection thing within a
servlet?
Code included below.
JSP Post to a Servlet. -> Servlet instantiates a FormBean ->
FormBean.validate() is called. -> but the validate() is always false because
the bean property vals are empty. Do I have to explicitly read each
request.getParameter("FORM_VAR") and set that to a bean property?
// from the servlet
//////////////////////////////////////////////
FormBean fb = new FormBean();
fb.setProperty(*); // ***** this aint workin - here *****
if (fb.validate()) {
URL = "WELCOME";
} else {
// go back
URL = "INDEX";
}
// from FormBean
//////////////////////////////////////////////
private String UserName;
private String Password;
public boolean validate() {
Debug.log (this, "validate","GETTING THIS FAR AT LEAST");
boolean allOk=true;
if (UserName.equals("")) {
errors.put("UserName","Please enter a username");
//UserName="";
allOk=false;
}
if (Password.equals("") ) {
errors.put("Password","Please enter a valid
password");
Password="";
allOk=false;
}
return allOk;
}
public void setUserName(String uname) {
UserName = uname;
}
public void setPassword(String pword) {
Password =pword;
}
public String getUserName() {
return UserName;
}
public String getPassword() {
return Password;
}
SORRY IF THIS IS MORE OF A STRAIGHT JAVA QUESTION THAN A TOMCAT QUESTION. I
AM USING TOMCAT. JI JI. TIA.
