RE: Commons validation framework and struts
Hello Ben, I am not using Dynamic forms. I have defined my own form object which derives from ValidatorForm. Are you saying that I must switch to dynamic forms if I want to use the validator framework? Or define my own validtors? One thing which I couldn't find in the validation framework was how to do validation only for a specific value. In my example I have operand1, operand2 and operator. If the operand2 is 0 and the operator is "/", then I would like to check this and raise an error "division by 0 not allowed" for other operators 0 is allowed for operand2. Actually with this prototype I was trying to find out how useful the validation framework is. Also, last time when I worked on struts the validation logic was put inside the form class itself. Is that still allowed? I also have some concerns regarding the use of the XML based validation framework. For my application, validation can get very complex. If I try to do everything via XML then the XML will get bloated and perhaps more complex than the java code. I would need advise from people who have used this framework for complex data validation to confirm whether it can easily be achieved and whether the xml code is easily understandable.

Re: What goes where?
I would say JDBC drivers should not be in the WAR file (WEB-INF/lib) but should go to container. I am wondering, why would you not use a DAO, for my own reasons, since there are questions on user list regarding JDBC, when I think DAO should be used (unless people using DAO just have no problems) and not JDBC; like why would once decide to use JDBC? (vs SQL based DAO like iBatis for example; but any DAO is much better than JDBC). .V Eric SCHULTZ wrote: Good afternoon...

Re: Repopulation fails after validation
You might have somehow cleared the loginForm bean at the beginning of the jsp, then when it is reshown, it is cleared. Remember that the logonForm was created automatically, and should still have your data. If you do a back, your data should also still be present on the original submit.

Newbie can't get saveErrors() working
Hi folks,
I'm in love with the validation framework included with Struts. The
fact that I can do validation with regular expressions and have
client-side JavaScript created for me automatically is fantastic.
However, there's one error that I have to catch on the server-side in
some cases: an attempt to create a duplicate entity. In this case, I'd
like an error message to appear close to the form input for which it
applies.
So I'm creating an ActionError in my Action and saving it as follows:
} catch (DuplicateDomainAliasError e) {
ActionErrors errors = new ActionErrors();
ActionError error = new ActionError("error.domainAliasName.exists");
errors.add("domainAliasName", error);
saveErrors(request, errors);
}
I have error.domainAliasName.exists in my message bundle:
error.domainAliasName.exists=A domain alias with that name already exists.
Because domainAliasName is a property of the ActionForm associated with
the I have in my JSP, I expect the message to be displayed
with the following tag:
However, that tag renders the empty string.
Can someone point out what I'm doing wrong here? I can get the error
displayed at the top of the page by using declarative exception
handling, but the page has a lot of stuff on it, and I'd like the error
displayed close to the form input that it relates to.
Thanks,
Sheldon.

form beans
hi! i have a page that shows user operations. Each user operation is represented as a userbean that includes info about the user and a Tree structure for functions that the user can make. the structure is eg: manage database agency table add edit delete this structure is managed through a TreeNode class. the action preceeding the page loads a list of user beans into session and in the page itself i iterate through the list. against each entry i have an edit and delete option. what i would like to know and do is that if someone clicks the edit button against a particular user, the values for that user are shows as editable form fields at the bottom of the same page.(the tree strutcure is displayed through checkboxes) how do i relate a an empty form at the bottom of the page to be filled with information depending upon the button clicked. i currently have an empty form to add a new user at the bottom. thanks ajay _ Hot chart ringtones and polyphonics.
