RE: Is Struts architecture a disadvantage?
You will not have heavily load if you put the ActionForm into the request scope. -Message d'origine- De : Yaman Kumar [mailto:[EMAIL PROTECTED]] Envoyé : vendredi, 7. juin 2002 08:51 À : Struts Users Mailing List Objet : Is Struts architecture a disadvantage? MessageHi, I have a question regarding struts architecture, As the Html form and its validation has been moved and implemented at server side ( a ActionForm ), once any validation error encounters that is shown in the same page from which this request is generated ( this is very impressing), but the page can't retain its old information other than form information. Case: An action class bound data into request scope with 3 different attribute names and forwarding to x.jsp which has got a form (XFORM) too. In x.jsp it received 3 different attributes and shown data in tabular format , when user submits this form to different action this form bean will be validated and if any errors encountered x.jsp page would be shown back to user, at this time user can't see the data that is shown tabular format. As request is new it can't hold the previous state, this compels the struts users to keep this data(3 attributes)in session scope so when user comes back he could see the error with the data too. In a big web application if we keep data in session scope the server/application become heavily loaded. Don't you think this is disadvantage of keeping /validating the formbean at server side. But I'm sure there are more and more advantages over this disadvantage. Please let me know if any better way to solve above problem and forgive me to understand this as a disadvantage of struts architecture.

Subject: Bug in struts-logic.tld - equal tag?
From: Scott Curtis [EMAIL PROTECTED]

Hi,
This is a difficult one to explain, so bare with me...
I have a bean class (MyBean) with various getters/setters for the
propertiescontained within it. Two of which are:
private boolean valid;
public boolean isValid() { return valid; }
private boolean aDTDFlag;
public boolean isADTDFlag() { return aDTDFlag; }
I then have a JSP using the struts-logic.tld tag library's equal
tag as
follows:
logic:equal name=mybean property=valid value=true
Do Something here!
/logic:equal
logic:equal name=MyBean property=aDTDFlag value=true
Do Something here!
/logic:equal
When I load this page I get:
javax.servlet.jsp.JspException: Exception accessing property
aDTDFlag for
bean MyBean: java.lang.NoSuchMethodException: Unknown property
'aDTDFlag'
The only way to make it work is to reference the aDTDFlag
property as
ADTDFlag within the logic:equal tag - ie with an uppercase
'a'?!? The
reference to the valid property is fine with a lowercase 'v'?
This isn't
working correctly because the property is named with a lowercase
'a' and
references to it shouldn't be forced to use an uppercase 'a'.
Am I correct? If so is this the right place to report this sort of
thing?
thanks

logic:iterator Class cast exception
Hi all,
I'm trying to iterate a Vector into a JSP page and I have an Class cast
exception. My vector contains an Hashtable that contains String object.
Here my ActionBean code for the iteration:
while(rs.next()) {
Hashtable table = new Hashtable();
table.put(SQLConstants.FieldName.BSP.BSP_ID,rs.getString(SQLConstants.Fi
eldName.BSP.BSP_ID));
table.put(SQLConstants.FieldName.BSP.BSP_FULLNAME,rs.getString(SQLConsta
nts.FieldName.BSP.BSP_FULLNAME));
vectorBsp.add(table);
request.getSession().setAttribute(Constants.BSP_LIST,loadBsp(errors));
}
Into my jsp, I iterate in this way.
logic:iterate id=%=Constants.BSP_LIST% name=bspList
tr class=TableValue
td%=
(String)((java.util.Hashtable)bspList).get(SQLConstants.FieldName.BSP.BS
P_ID)%
td%=
(String)((java.util.Hashtable)bspList).get(SQLConstants.FieldName.BSP.BS
P_FULLNAME)%
/tr
/logic:iterate
Here the error message.
