Say if I have two text fields, one label is Please enter name:, and the
other label is Please enter SSN:. In struts validator framework, if I
need to validate these two fields using required validator, is there any
way to relate the field label to the message? Or does struts validator
support displaying the validation message right next to the field (so
that the user easily know which fields are invalid)?
Thank you very much.
Attachment:
user_186499.ezm (zipped)You define the field label using an argument, i.e.
<field property="username" depends="required">
<arg0 key="prompt.username"/>
</field>
So the validator is using the field's label to fill in the message. The default message for errors.required is:
errors.required={0} is required.
So, it will replace {0} with the prompt.username entry that also appears as a resource.
To display the error next to the field, you could place an <html:errors property="username" /> next to the field. IF you do this though, realize that Struts is going to place the errors.header, errors.footer, errors.prefix and errors.suffix around the items. If you use the defaults that would not look right next to a field - fine for the top of the page, but not for a field. You'll have to change them.
Otherwise, you could use an <html:messages> tag specific for that field and then format the html yourself as it iterates one (or possibly several) error messages for each field.
Good luck,
Eric

user_186500.ezm (zipped)In my application "id" attribute is int type of "Group" bean.
In my JSP I have written like that :-
<s:textfield name="group.id" value="%{group.id}"/>
Now if user puts a string into this text field, then error message come like
that
*invalid value for the field group.id
But I want to show the error message with only "id" not "group.id".
Is there anybody, who can show me any example how to do that.

Attachment:
user_186507.ezm (zipped)Read the section "Type Conversion Error Handling" in:
http://struts.apache.org/2.x/docs/type-conversion.html
You need to define an "invalid.fieldvalue.<your property>" to do custom
type conversion error.

Hi,
Im looking for a nice and easy way to alter the color of every second
textfield.
We are yousing a custom theme to render the textfields including a tablerow.
Is something like this possible?
<s:textfield cssClass="%{++itemcount % 2 = 0 ? blue : red}" ...

<s:if test="#status.odd">
<s:set name="class" value="'rowdark'" />
</s:if>
<s:else>

user_186508.ezm (zipped)Hi,
then you could have this managed by your action class creating
a getter method for your counter.
Maybe something like that:
Action.class:
public void initCounter() {
this.counter=0;
}
public int getCounter() {
return counter++;
}
Your JSP:
<s:if test="counter%2!=0">
<s:set name="class" value="'rowdark'" />
</s:if>
<s:else>
<s:set name="class" value="'rowlight'" />
</s:else>
Might work :)

Yes you are right...might work :-) but not very nice. Putting such things
into an action is not the right way I think. Is there no way doing this with
freemarker themes.

I suggest you use FireBug or the HttpHeaders plugin for FireFox to
examine the header for the response from your action compared to a wmv
served directly by the container. It's likely that the
Content-Disposition header, Content-Size or Content-Length is
incorrect. You'll probably need to change the parameters passed to the
StreamResult.

user_186509.ezm (zipped)Hi,
I am new to Struts2 and stumbling immediately.
I want to have an initialization routine in my web app which will connect to a data base etc. at startup time. This routine needs some parameters (e. g. the path of a config file to be read). How can I access such external information?
With Servlets I would normally implement a ServletContextListener which would get its information as an init-param from web.xml.
But for Struts2 there is no <servlet> spec where I could put it.
Writing Struts1 applications I typically utilized a plugin which could read parameters from struts-config.xml. Maybe this is still possible, but the Struts2 plugin mechanism seems to be too powerful (or just overwhelming) for me.
What is the preferred way?
Thanks
Martin

user_186515.ezm (zipped)hi Martin,
I here, do not use Spring nor hibernate and indeed need defining a
ServletContextListener implementation that I configure in web.xml that
initializes database connections etc.
In an ideal world:
- You are starting a new web application project from scratch
- You are open to see best practices and learn by example
- You do not have constraints on which technologies to use (e.g. Spring,
Hibernate, Sitemesh, etc)
THEN
Please do yourself a favor an use AppFuse, it will give you a beautiful
Struts 2 application setup out of the box including user-management and
authentication on top of MySQL database. The only thing I can complain
about it though is its usage of sitemesh where I prefer tiles. Maybe
their GenericDao implementations could be polished as well.
Checkout their web site: http://appfuse.org/display/APF/AppFuse+QuickStart
Basically you only need to:
1) Install maven & subversion & MySQL
2) mvn archetype:create -DarchetypeGroupId=org.appfuse.archetypes
-DarchetypeArtifactId=appfuse-basic-struts
-DremoteRepositories=http://static.appfuse.org/releases^
-DarchetypeVersion=2.0.2 -DgroupId=com.mycompany.app -DartifactId=myproject
3) cd myproject and execute "mvn appfuse:full-source"
Then you can start a full forensic analysis on it :) and get the idea
how to structure a beautiful web app :) they even offer a tutorial how
to get you going from that point on.
HTH,
regards,
Giovanni

user_186516.ezm (zipped)Spring is kind of mighty to use just for some initialization parameters;
however, using Spring for dependency injection provides greatly improved
management of object dependencies for the rest of your app.
My current app is a Spring / Struts 2 app running on Tomcat.
Here is a quick overview of how I'm using Spring with Struts 2 -- I will
address your specific question after the basics below.
In my Spring configuration file (applicationContext.xml), I have all my
various beans wired together, including my Struts actions. So, for
instance, I have a UserDetailsService bean that has a reference to my
UserDao, and a UserDetailsAction that has a reference to the
UserDetailsService:
<bean id="userDao" class="com.bogus.dao.UserDaoImpl"/>
<bean id="userDetailsService"
class="com.bogus.service.UserDetailsServiceImpl">
<property name="userDao" ref="userDao"/>
</bean>
<bean id="userDetailsAction" class="com.bogus.action.UserDetailsAction">
<property name="userDetailsService" ref="userDetailsService"/>
</bean>
Then, in struts.xml, I don't have a direct reference to my UserDetailsAction
class -- instead I have a reference to the Spring-managed bean:
<action name="userDetail" class="userDetailAction" method="input">
<result name="success" type="redirect-action">userList</result>
<result name="input">/WEB-INF/secure/admin/userDetail.jsp</result>
</action>
Now -- as to your specific question. If your database connections are
handled by an object of a specific class, you can use Spring to inject the
necessary values into your database connector object. Something like this:
<bean id="databaseConnector" class="com.bogus.db.Connector">
<property name="driverClassName" value="
com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost/" />
<property name="username" value="dbUser" />
<property name="password" value="password" />
</bean>
This is actually not ideal if you're going to be migrating this application
through various environments. Better than this would be to set up a context
file in each environment and refer to it in your Spring configuration. But
if you're in the early dev stages, this works well.

user_186520.ezm (zipped)Struts2 doesn't stop you from implementing a ServletContextListener. In
fact in the Appfuse Struts2 application there is a StartupListener (extends
ServletContextListener) that does what you talk about.
It just so happens that Appfuse also uses Spring to configure its services
including its database connections. So in this StartupListener there is
some configuration read from web.xml
ServletContext context = event.getServletContext();
String something = context.getInitParameter(name_of_paramerter);
But it also initializes things like static drop-down lists for HTML selects.
It does this by connecting to the database using Spring managed beans. The
database related Spring managed beans are configured as such:
<bean id="propertyConfigurer"
class="
org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath:jdbc.properties</value>
</list>
</property>
</bean>
<!-- JNDI DataSource for J2EE environments -->
<!--<jee:jndi-lookup id="dataSource"

It also uses Hibernate, so there is a SessionFactory bean that references
this DataSource bean and then DAO classes that reference the SessionFactory
bean, but that is beyond this discussion I think.
What you see above is how an external property file is declared and then
those values included in configuration of a Spring managed bean.
The ServletContextListener gets these Spring beans by doing the following:
ServletContext context = event.getServletContext();
ApplicationContext ctx =
WebApplicationContextUtils.getRequiredWebApplicationContext(context);
(BasicDataSource) ds = ctx.getBean("dataSource");
The last interesting part of this example/topic is that the listener looks
up the list of values from the database and then puts them into the
ServletContext to be access later by struts tags.
List options = ...some jdbc that returns a list....
context.setAttribute("optionListName",options);
Then later on in a page:
<s:select list="#attr.optionListName" .... /> (Uses OGNL to get
something from the ServletContext)

user_186518.ezm (zipped)I'm just not sure when I put listValue = "name" and listKey="id" I get
and emtpy combo box with exactly 4 places (it have value option good) ?
One more thing, if I have object Person buyer; in my Fruit class (with
get/set methods), and I have Fruit fruit object in my action class,
where I also have List<Person>allBuyers in my action class. How can I
define combo box so that when buyer is selected, that Person object should
be set to my fruit.buyer object ?
When I removed listKey then it works good. But I now have the same
problem with my datetimepicker field. I have "date" attrib (of type
java.util.Date with get/set methods) in my Fruit class. I have defined it in
jsp like this:
<s:daettimepicker name="fruit.date" id="fruit.date"
displayFormat="dd.MM.yyyy" label="Date" type="date"/>
?

Ok.. if i get your idea... the list yout want to put in combobox is
fruit.buyers, hummmm?
Then, try it:
listKey="personId" name="fruit.buyers" emtpyOption="false"
hedaerKey="none"/>
if you have the object fruit, then:
listValue="personName" listKey="personId" name="fruit.buyers"
emtpyOption="false" hedaerKey="none"/>
maybe the name is not correct. Try chage the attr name to person, for
example.
listValue="personName" listKey="personId" name="person" emtpyOption="false"
hedaerKey="none"/>

user_186519.ezm (zipped)I fixed my first problem, it was naming issue. But I still have this question:
If I have object Person buyer; in my Fruit class (with
get/set methods), and I have Fruit fruit object in my action class,
where I also have List<Person>allBuyers in my action class. How can I
define combo box so that when buyer is selected, that Person object
should be set to my fruit.buyer object ?
Now I have the same
problem with my datetimepicker field. I have "date" attrib (of type
java.util.Date with get/set methods) in my Fruit class. I have defined
it in jsp like this:
<s:daettimepicker name="fruit.date" id="fruit.date"
