Problem while setting object directly from s:select tag
Hi,
I am having problem while setting my selected list object directly to my
bean class.
My code looks like given below:-
s:select name=user.item list=itemList listValue=name/
public MyAction extends ActionSupport {
...
public ListItem getItemList() {
return (a list with itemobjects in it);
}
public User getUser() {
return user object;
}
}
public class User {
private Item item;
public Item getItem() {
return item;
}
public void setItem(Item item) {
this.item = item;
}
}
public class Item {
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
My listKey contains the Object of type Item.
But when i am trying to save my user object gives me following error.
Error : Invalid field value for field user.item.
Can anybody help me to find solution.
Thanks in advanced,
Jignesh

Debug shows that the code in the action method is executed, but the browser shows an empty page after executing the action. I would expect that simple nothing would happen (as the real download functionality/the response) isn't implemented yet. It's perfectly normal! Since you are forwarding to nothing, a response MUST be sent to the client, and it is a default response (no content, but the HTTP headers are present). To be more precise, I'd expect the browser to show the search mask and the result still. Do you mean that you expected that the original page is still present after that request? This is true, if the file is not HTML, plain text, and other formats that are directly interpretable by the browser. If you put in the response, say, a zip file, your browser will ask you to save/open it (possibly you have to set the Content-disposition HTTP header parameter). Antonio
[S2] validation annotation problem
I use model driven actions and want to use validation by annotation.
so I have somethings like:
@Validation
public Class ...Action implements ...{
...
@VisitorFieldValidator(message = , appendPrefix = false)
public TestModel getModel() {
return testModel;
}
...
in the model class TestModel I have:
@Validation
@Entity
@Table(name = ...)
public class TestModel implements IPersistable {
...
@VisitorFieldValidator(message = )
public void setSubModel(SubModel subModel) {
this.subModel = subModel;
}
...
(beside validation you see some hibernate annotations)
Now the problem I see when debugging (JBoss 4.0.3SP1) is:
the first VisitorFieldValidator is recognized correctly, but within the
TestModel class no annotations at all are found!
when I write a simple unit tests which does pretty the same then in the
validation annotation logic of struts2 / xwork, I get the annotation!
What is difference / problem here?
the units tests found the Annotation (size of array = 1),
debugging real application shows size = 0
(yes I am sure I have deployed the same class which is used in Unit Test)
Part of Unit Tests (which works) is:
@Test
public void testGetAnnotation() {
TestModel testModel = new TestModel();
Method[] methods = testModel.getClass().getDeclaredMethods();
for (Method method : methods) {
if(method.getName().equals(setSubModel)){
System.out.println(method: + method.getName());
Annotation[]annotations = method.getAnnotations();
System.out.println(annotation size: +
annotations.length);
}
}
}
Any help highly appreciated,
thank you in davance

Re: struts 2 action messages / action errors
Struts 2 allows you to style them, but using themes. Themes are both more powerful and more complicated than what Struts 1 offered. Before you dive into customizing a theme, see if you can style it entirely with CSS. You're best better is probably to View source in your browser to see the rendered HTML, noting the classes that the built-in themes use. Then, override these styles with your own stylesheet. Using the built-in css_xhtml theme (add struts.ui.theme=css_xhtml to struts.properties) will give you more flexibility, compared to the default theme (xhtml). If that doesn't give you the look you want, it's time to dive into themes. Themes are documented here: http://struts.apache.org/2.x/docs/themes-and-templates.html http://struts.apache.org/2.x/docs/extending-themes.html Mark Menard has provided an excellent tutorial on creating custom themes here: http://www.vitarara.org/cms/struts_2_cookbook/creating_a_theme On Oct 24, 2007, at 11:58 AM, Brian Relph wrote: Does struts2 handle the css-styling of action errors and messages the same as struts1?

Validation Best Practices?
Hey,
I have a question concerning where validation should be performed, and
what people feel best practices are. Specifically, I have a number of
business objects that validate parameters supplied to their setters
for correctness, and throw IllegalArgumentExceptions if something is
invalid. For example, in a hypothetical Person class I would have:
...
public void setAge(int age) {
if (age 0) throw new MyInvalidValueException(some i18n-ed
error msg);
this.age = age;
}
This is done so that if there is a failure to properly validate at
some other layer of the application, it will fail-fast and allow the
problem to be debugged more easily. (It also gives confidence that all
references to a business object do not contain invalid data.)
Now, we are using Struts2 and intend to use the provided annotations
for validation. The problem is, if I create the app so that HTTP
parameters are set directly on the business objects (by using a 'name'
value of person.name for a form field, for example), these
exceptions will prevent the value from being set, so validation is
never performed (and no errors are set on the action).
The way I see it, I have three options:
1) Remove all validity checks from the business objects, and rely on
Struts to validate incoming data, and the DAO layer to validate them
before inserting. This would probably be the simplest option, but I
wanted to get peoples thoughts on it first. Are argument checks like
the ones above a good idea? Or is it better to have these type of
objects be dumb-data transfer objects that will carry any value they
are given?
2) Duplicate all properties of the business objects on the struts
actions, where they can be validated using the validation annotations.
The action methods must then copy the values into the business objects
as needed. This would allow the business objects to remain unchanged,
but has a lot of duplication and maintenance overhead if fields are
added/removed/changed. (It basically reminds me of the nightmare of
Struts1 form beans :p )
3) Extend the ParametersInterceptor and/or validation interceptor to
do some kind of magic involving catching the argument exceptions,
setting appropriate errors on the action, and preserving the invalid
values so that they can be redisplayed on the form. This option is
definitely the most work (and I haven't looked at the Struts source
closely enough to know exactly how much is involved, and if its even
possibly to do in an elegant fashion).
So in addition to commenting on the above specific situation, the
general question is this: should business objects be self-validating,
and how should they handle validation errors?
Thanks in advance for any input,

Re: [S2] Websphere 6.1 Showcase application, Response already committed warning in logs
Hi, I am using RAD 7.0 with WAS test environment. My Struts2 app is not working (There is no Action mapped for action name - error) in the test environment. I exported my project as WAR and deployed it in the app server. This time it worked. I observed the same behavior even with the Struts Blank application. With resources in my workspace, it is not working but when I deploy the app as WAR it is working. I even upgraded to WAS 6.1.0.5 Fix pack but with no luck. Could anyone explain the reason for this strange behavior? Thanks Antony Stubbs wrote: Great news guys - problems solved. Everything now seems to be working great. So - to get it working, i installed the 6.1.0.5 fix pack, and the http://www-1.ibm.com/support/docview.wss?rs=0uid=swg24014758 interim fix for PK33090 . There is another related issue:PK27620. Now here's the key - what you also have to do, is set com.ibm.ws.webcontainer.invokefilterscompatibility custom property on your web container settings to 'true' for the fix to take effect. Hoorah! The struts2-blank, struts2-showcase also works great, as well as the AJAX pages! And my app as well - along with SiteMesh decoration! When a request is made for a file that does not exist at the location specified in the request the Webcontainer calls the filters (if any) associated with the request. If the filters were able to find the requested resource the request is supposed to continue on as normal. However the webcontainer is sending back a 404 error even though the filters were able to find the resource. AND If a JSP is accessed using a URI that does not exist as part of a web application (but can be mapped via a servlet filter), a 404 File not found exception will be reported. http://forum.springframework.org/newreply.php?do=newreplynoquote=1p=100026 pea1: I got a response from IBM. They ackowledge this problem and gave me a work-around. Quote: One of our level 2 technicians stated this about the apar... APAR PK27620 changed a lot of the code dealing with filters.

So we had to add a new custom property for 6.1.0.3+ The custom property he is talkin about is; com.ibm.ws.webcontainer.invokefilterscompatibility The com.ibm.ws.webcontainer.invokefilterscompatibility should be set to true through Application Servers - server - Web Container Settings - Web Container - Custom Properties.

Re: about Struts 2.0.9 portlet example ...
Ok thanks, that's good to know. There is a strong recommendation coming from a colleague to use the IBM Portlet API on WebSphere Portal, particularly because of its support for inter-portlet communication - from what I'm told, this isn't supported by the standard JSR-168 API. I'm not too keen on using proprietary extensions, unless it does provide a significant advantage. Would Struts2 provide the necessary mechanism to accomplish this communication? What are the advantages of using Struts2 on top of the standard portlet API or the IBM API?

[S2] [S2.0.9] s:submit method=.../ v. Ajax
Howdy, If you have an s:submit.../ with method='' or name='method:foo' attributes and set theme='ajax' is the method attribute/name-thing ignored? Thanks, Dave - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

2.0.9 OptionTransferSelect
I am trying to upgrade our app to 2.0.9 and having difficulty in the
optiontransferselect tag.
Here is a sample of what a typical OTS tag looks like in our app:
-
s:form name=editForm2 action=saveScanNotifications theme=xhtml
s:optiontransferselect
theme=xhtml
label=%{getText('item.notifications')}
name=systemUsers
rightTitle=Users Notified by Scan
leftTitle=System User List
list=%{systemUsers}
listValue=email
listKey=id
allowAddToLeft=true
allowAddAllToLeft=true
allowUpDownOnLeft=true
multiple=true
headerKey=headerKey
headerValue=--- Please Select ---
emptyOption=true
doubleList=%{notificationUsers}
doubleListValue=email
doubleListKey=id
doubleName=notificationUsers
doubleHeaderKey=doubleHeaderKey
doubleHeaderValue=--- Please Select ---
doubleEmptyOption=true
doubleMultiple=true

In versions previous to 2.0.9, the associated action executes
perfectly and everything works. The execution order in the action
layer goes like this:
1) Prepare is called.
2) saveScanNotifications (method in Action mapped class) is called.
3) Prepare is called.
In 2.0.9 the associated action executes in a different order and thus
throws NullPointerExceptions. Here is what happens in 209:
1) Prepare is called.
2) Prepare is called.
3) saveScanNotifications (method in Action mapped class) is called.
When the above happens the first prepare works and retrieves the
object from the db by id correctly. When the second prepare happens,
all of a sudden there is no id to load , or object present from the
previous prepare. Almost like it is being called without any
knowledge of the request context. Then saveScanNotifications is
called and exceptions hit everywhere b/c the object was not loaded.
Does anyone have an idea on what might have changed in 2.0.9 or where
we may have gone wrong?
Thanks,
Brian-

Struts 2 and Tomcat JDBCRealm
Hi, I am trying to add user authetication using tomcat JDBCRealm in my struts-2 application. But I don't seem to get it working. Has anyone tried it ? I have configured web.xml and my context.xml for Form based validation. but after I click submit, it goes back to error page described in web.xml for Realm. I would appreciate if you could describe me steps. Leena - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: about Struts 2.0.9 portlet example ...
It is true that inter portlet communication is not supported in the JSR168 spec, but there are ways to exchange data between portlets in a less proprietary manner. The easiest way is to use the shared session scope which is available to all portlets in the same portlet application (same war file). So if you have portlets that need to communicate, put them in the same application (which they probably should anyway, since they obviously have some relation). Without having tried it, you might also be able to build something on top of a distributed caching/JMS/database system. The Portlet 2.0 (JSR 286) specification includes support for inter portlet communication. The main advantage using Struts 2 (or any web framework that support portlets) is that you get a framework on top of the portlet API. I am not aware of any framework support for the IBM Portlet API (besides a custom struts framework that really wasn't any good the last time I tried it), so it would be like programming servlets in a web application. But still, if you know that inter portlet communication will be important for your application, and none of the proposed solutions are good enough for you to use, I guess you don't have a choice but lock yourself to a vendor. Nils-H On 10/24/07, Guillaume Bilodeau [EMAIL PROTECTED] wrote: Ok thanks, that's good to know. There is a strong recommendation coming from a colleague to use the IBM Portlet API on WebSphere Portal, particularly because of its support for inter-portlet communication - from what I'm told, this isn't supported by the standard JSR-168 API. I'm not too keen on using proprietary extensions, unless it does provide a significant advantage. Would Struts2 provide the necessary mechanism to accomplish this communication? What are the advantages of using Struts2 on top of the standard portlet API or the IBM API?

It does not include Ajax support, but you can add that yourself. I know of several projects that are using it in production already.
