Re: Validation with DynaValidatorForm not working - help
I guess that would work if you have validations corresponding to a
form i.eyou are extending DynaValidatorForm.
If you need to extend DynaValidatorActionForm, i.e give validations
corresponding to a action (as single form can be reused in different actions
and not all fields need to be validated in each case) then I feel you need a
call to validate.
Correct me if I'm wrong :-)

Re: Validation with DynaValidatorForm not working - help
You are right that there is no need to create a form bean if you are using
dyna form.
However if you want to link your form with the validation framework then you
do need to create a local form bean. This form bean would not have any
attributes and their getter and setter methods as they all are defined in
Struts config.
All it would contain is a validate method with a call to super.validate().
Please refer to the sample code in my last note for reference.

Re: Enabling links according to user's authorization
Hi,
To check the users access the best approach is to check the access on the
action by giving the roles attributes in the Struts Config and overriding
the processRoles() method of action class.
In addition to this if you want to limit weather a link is dispalyed to the
user or not you can take help from the following custom tag code and create
one for your application on similar grounds.
Tag Class
public class RolePresentTag extends TagSupport {
private String _role = null;
public void setRole(String sRole) {
_role = sRole;
}
public String getRole() {
return _role;
}
public int doStartTag() throws JspTagException {
boolean present = false;
ResourceBundle bundle = null;
HttpServletRequest request = null;
String roleName = null;
StringTokenizer st = null;
try {
bundle = ResourceBundle.getBundle(Constants.RESOURCES);
request = (HttpServletRequest) pageContext.getRequest();
st = new StringTokenizer(_role, ",", false);
while (st.hasMoreTokens()) {
try {
roleName = bundle.getString(st.nextToken());
} catch (MissingResourceException e) {
continue;
}
if (Util.isUserInRole(roleName, request)) {
present = true;
break;
}
}
} catch (Exception ex) {
throw new JspTagException(ex.getMessage());
}
return present ? EVAL_BODY_INCLUDE : SKIP_BODY;
}
public int doEndTag() {
return EVAL_PAGE;
}
}
Util.isUserInRole :
In this method track the current role of the user from session and check if
it is one of the assigned role for this link
tld :
http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_1.dtd";>
1.0
1.1
rolepresent
present
com.util.tag.RolePresentTag
JSP
role
true
true
JSP Code :
Hope this solves your problem.

Re: Validation with DynaValidatorForm not working - help
Hi,
Simply having your dyna form bean of the type Dyna Validator form will not
work. You have to declare your form bean in the Struts Config as type any
local form bean you have. ( )
Then your ABCForm will extend DynaValidatorForm or DynaValidatorActionForm
depending on yor requirement.
It would have code similar to one given below
public class LoginForm extends DynaValidatorActionForm{
public ActionErrors validate(ActionMapping mapping, HttpServletRequest
request) {
ActionErrors errors = null;
errors = super.validate(mapping, request);
return errors;
}
}
Hope this solves your problem.

Re: Validation Problem - very urgent please reply
Hi,
I feel that the approach given by Peter would be fine.
You might be populating the drop down by iterating a collection fetched from
Database. When you submit the form only the selected value is submitted from
the drop down not the entire collection (That is why you do not get the
collection back on page load after validation failure).
Ideal workaround is to iterate the entire collection again within the JSP
and submit the same as hidden.
If your collection is of some object having attributes like id and value
then you need to submit two separate collections one for each type of
attribute.
In this case you need to ensure that in your form bean if there is a
validation error you need to map the hidden collection back into the form
just the way you do it while loading the page from the action class. You
will need to iterate through both the collections and remake the collection
of objects from the same and set it into the appropriate form property.
Please let me know if you need any further information.
Regards,
Vishal
