Form and Pass the Form to the Business Tier

2003-12-23 Thread Caroline Jen 
My JSP provides several text fields for visitors to
fill out.  And my form bean stores those information;
for example:

public String getThreadTopic() {
return threadTopic;
}
public void setThreadTopic(String threadTopic) {
this.threadTopic = threadTopic;
}

public String getThreadBody() {
return threadBody;
}
public void setThreadBody(String threadBody) {
this.threadBody = threadBody;
}

However, I have to supply a number of additional
properties for the business tier to process.  For
example, the property threadType is to be assigned to
zero manually and the property parentPostID is to be
found from another class, how do I code them in the
form bean?  Do I use get methods shown below (without
set methods)? 

public int getThreadType() {
   return 0;
}

public int getParentPostID() {
   return ParamUtil.getParameterInt( request, parent
);
}

This is fine I assume.

 public int getParentPostID() {
return ParamUtil.getParameterInt( request, parent
 );
 }

This wouldn't work properly.  I would make a setter for parentPostID and in
the jsp write something like:
html:hidden name=yourformname property=parentPostID value=%=
request.getParameter(parent)%/

HTH,

Thank you for your response.

According to my understanding of your advice, if I
want to pass a hidden field from JSP to a form bean, I
must have name=myFormName in the JSP's html:hidden
  tag?  Please confirm.

Another additional property that is to be assigned a
value in my form bean is now with Timestamp type. 
Do I code this way in my form bean class?  Please
confirm:

pubic Timestamp getNow() {
   return DateUtil.getCurrentGMTTimestamp():
}

 must have name=myFormName in the JSP's html:hidden
   tag?  Please confirm.

From the docs:
The attribute name of the bean whose properties are consulted when rendering
the current value of this input field. If not specified, the bean associated
with the form tag we are nested within is utilized. (RT EXPR).

I always put it as good practice.

 Another additional property that is to be assigned a
 value in my form bean is now with Timestamp type.

 confirm:

 pubic Timestamp getNow() {
return DateUtil.getCurrentGMTTimestamp():

Ya that looks fine.
