RE: JAAS struts 2 Tutorial?
Better a late replay than none at all :) > Is JAAS the best way to go, or there are better alternates? 'JAAS' encompasses a lot of stuff, so it depends what you are trying to do... Let me assume for the minute that you are talking about login/authentication... In this case, it depends whether you need your user to be authenticated to your J2EE container or not. (If for example you want to control authorisation to any EJBs that you call via their deployment descriptor, then you will need to be authenticated to the container ) JAAS will give you this, but unfortunately will require you to write a server specific LoginModule for every server you need to support. If, however, you don't need this, then something like Acegi (http://www.acegisecurity.org/) will give you a more portable solution cheers Perryn -Original Message- From: news [mailto:[EMAIL PROTECTED] On Behalf Of Muhammad Momin Rashid Sent: Wednesday, 12 September 2007 7:32 PM To: user@struts.apache.org Subject: JAAS struts 2 Tutorial?

RE: [s2] Struts head tag KILLS (> 10s) page load time
Ah, thanks Musachy, that explains what I was seeing.
The total latency experienced for the dojo files to load every time was
pretty high when running over a long distance, as the files are requested
sequentially, rather than as parallel requests... Not sure what the best
solution would be to this one apart from customisation of the dojo
includes??

Re: Newbie question about parameters for an Action
I presume you mean org.apache.struts2.servlet.ParameterAware. If I implement
setParameters(), it is not called before the execute() method. I'm still in

RE: [s2] Struts head tag KILLS (> 10s) page load time
Hi Martin,
Yes, that's right.
The dojo "requires" seemed unexpectedly slow during our tests. I was using
Firefox's Firebug to check page load times. From memory, it looked like the
dojo includes were being requested sequentially and seemed to give
substantial page loading overhead (>2s) even if the dojo .js files were
cached.
I never fully understood why there was a large overhead although the dojo
files were supposedly cached. It might have been a quirk with firebug and
dojo "requires", or maybe the "requires" routine itself is slow, when called
30+ times.
About 5 dojo files were consistently returning "not found" as well, which
may not have helped the load times.
Removing as much dojo stuff as I could, and upgrading from Struts 2.0.8 to
2.0.9 has solved our page load time issues.
Regards
Jason

Newbie question about parameters for an Action
I would like to draw a Pie Chart using JFreeChart. I call the action from a

The action is very simple:

private int kinesthetic;
public String execute() {
System.out.println("Visual: " + getVisual());
System.out.println("Auditory: " + getAuditory());
System.out.println("Kinesthetic: " + getKinesthetic());
DefaultPieDataset pieDataset = new DefaultPieDataset();
pieDataset.setValue("Visual", getVisual());
pieDataset.setValue("Auditory", getAuditory());
pieDataset.setValue("Kinesthetic", getKinesthetic());
chart = ChartFactory.createPieChart("Learning Profile",
pieDataset, true,
true, false);
return SUCCESS;
}
public JFreeChart getChart() {
return chart;
}
public int getVisual() {
return visual;
}
public void setVisual(int visual) {
this.visual = visual;
}
public int getAuditory() {
return auditory;
}
public void setAuditory(int auditory) {
this.auditory = auditory;

Re: [s2] How do I output unicode characters please help
Er, no; property files are required to be in ASCII format. Using a UTF-8 character encoding in a properties file will not work. @Dave: ü is a valid encoding of the character \u00fc, it's equivalent; in fact, I think it's equivalent regardless of character encoding for the served HTML, which would make it the most portable representation. Why do you want something else? If you really can't work with the encoded output, you may be able to get the raw character, for example with escape="false"/>. L.

[EMAIL PROTECTED] wrote: If your action class implements ModelDriven and Preparable and your prepare method returns a null object, ParameterInterceptor tries to set the parms which are names appropriate to properties in model object that is expected to be on the top of stack. However, since model was null, it was NOT SET on top of the stack and all the parameters are now looked for in the action class. They are not found there (naturally) so all the parm setters fail. Should the ModelDriven interceptor create a model when it is null? This is as documented [1]: "Note: The ModelDrivenInterceptor will only push the model into the stack when the model is not null, else it will be ignored." When implementing ModelDriven, it is your action's responsibility to create the model. Whether you choose to accomplish that in a prepare() method, or by other means, is up to you. L.

Re: Spring tutorial
You might also look at the 'Core J2EE Patterns' book (also now online at sun) and look at the 'Service Locator' pattern. (This assumes the DB is registered with a central registry, as it usually is.) Most of the book's examples are about EJB (ugh), but there is a good example there of setting up access to a database with good architecture. They have sample code (example 7.8) which you can probably use with almost no modification. They also have some good advice there about separating Data Access code from the rest of your app. What you need to keep in mind is that these things are not really different in Struts than in another programming mode. Struts only wires thing together for you, and the way you design your app and the code you write isn't that much dependent on the framework (or at least, it shouldn't be). So you need to learn the framework, but more important, you need to know the fundamentals of how to design your app so that it has the least dependence on the framework. When you build a house, it shouldn't matter what kind of vacuum cleaner you use. In the same way, when you build an application, it shouldn't matter too much what the provider framework is. The framework just provides services which you app can use. But if that service was not available thru the framework, you could get it some other way, and then the *use* of that service wouldn't have to change. Look at Struts as a big bag of nice services you can use, and then your app uses those services. If you went to another service provider, not everything would have to change. If it does, then that is an indication that your architecture doesn't properly separate concerns. Of course, all that is 'theory', and implementation always has to make compromises. But it helps to keep it in mind as an ideal. - Ray Clough > - Original Message - > From: "Nuwan Chandrasoma" <[EMAIL PROTECTED]> > To: "Struts Users Mailing List" > Subject: Re: Spring tutorial > Date: Mon, 24 Sep 2007 00:16:03 +0530 > > > Hi, > > you can use the same approach you used in servlets. if you use > spring it will help you write the code in more elegant way :) > > Thanks, > > Nuwan > > rama krishna yalagandula wrote: > > Yes...

modified the styles.css file in template/xhtml, and also the one in

Hi Rama Krishna, you can still use the same JDBC thin driver, in fact since your learning curve with struts is quite steep, I would suggest you just take a good example of your usage of JDBC and encapsulate it using the Factory design pattern for instance, and then call your factory classes from your struts actions. It would be good to keep the actions and the database access seperate. Then at some future point once you are further up the learning curve, you can decide whether to use Spring.

Mapping multiple enums to a nested object
Hi all,
I'm quite new to Struts2 and so far I love what I see. Currently I'm having
a problem trying to map a checkboxlist based on a set of enums to a model
object nested in my action. Here's what I have now:
JSP:
Action:
public class CreateSimpleFoodAction {
private FoodService foodService;
private SimpleFoodCreationRequest foodCreationRequest = new
SimpleFoodCreationRequest();
public CreateSimpleFoodAction() {
}
public String prepareNewSimpleFood() {
return Action.SUCCESS;
}
public String createSimpleFood() {
String result;
try {
foodService.createSimpleFood(foodCreationRequest);
result = Action.SUCCESS;
}
catch (FoodException e) {
result = Action.INPUT;
}
return result;
}
public SimpleFoodCreationRequest getModel() {
return foodCreationRequest;
}
public List getAvailableGroups() {
return Arrays.asList(Group.values());
}
public List getAvailableNutrients() {
return Arrays.asList(Nutrient.values());
}
public void setFoodService(FoodService foodService) {
this.foodService = foodService;
}
}
Model:
public class SimpleFoodCreationRequest implements SimpleFoodPropertyProvider
{
private String name;
private Group group;
private Set nutrients = new HashSet();
public SimpleFoodCreationRequest() {
}
public Group getGroup() {
return group;
}
public void setGroup(Group group) {
this.group = group;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public void setSelectedNutrients(Nutrient[] selectedNutrients) {
nutrients.clear();
for (Nutrient n : selectedNutrients) {
nutrients.add(n);
}
}
public Nutrient[] getSelectedNutrients() {
return nutrients.toArray(new Nutrient[0]);
}
public Set getNutrients() {
return Collections.unmodifiableSet(nutrients);
}
}
CreateSimpleFoodAction-conversion.properties:
model.group=com.opensymphony.xwork2.util.EnumTypeConverter
model.selectedNutrients=com.opensymphony.xwork2.util.EnumTypeConverter
Element_model.selectedNutrients=com.gb1.healthcheck.domain.nutrition.Nutrient
When I submit this form, the selected checkbox list items are not mapped to
my SimpleFoodCreationRequest object. The console shows the standard message
"error setting 'model.selectedNutrients' with..."
Any ideas?
Thanks!
GB

Re: [S2] Hooking up custom interceptors (Annotations)
Thank you Dave and Adam. I;'ve tried both suggestions. 1) Changing away from annotations, works an "proved" that my interceptors do work outside of their unit tests and actually in the system. 2) Trying the ParentPackage Annotation, works. I had read about this annotation, but convinced myself it wasn't what I was needing... Since I thought I needed to set the XWork Package for my action, not the Parent Package of the XWork Package... though given the way package inheritence works, I should have realized it would work. Now, I really want to use annotations instead of xml where possible, but the ParentPackage approach doesn't feel as clean/DRY as i would like. Configuring the interceptor stack (and global results) in XML is acceptable, since the only other options would tend to require place holder do-nothing classes to annotate. However having to annotate every action with a ParentPackage is very wrong. It feels like something like one of the following options would be needed and I can't tell if anything like this exists yet: 1) Provide some way for a default package to be declared in the struts.xml file 2) Make the actionPackages auto-detection set the XWork package based on the java package in some predictable fashion. (Not just the namespace as currently documented. ParentPackage could still override this default when needed for flexibility. 3) Move towards the "do-nothing" class to hold annotations -- some sort of ActionPackage interface... Might be able to make it slightly less useless by allowing anonymous interceptors to be defined/configured here if they don't need to be re-used in other packages? Is there some other appraoch to linking all "Zero Configuration" actions to a specified package without repeating it in every action? What could also be useful -- extend the config-browser plugin to expose an action's XWork package. It would definitely help with debugging/checking what XWork package an auto detected actionPackage is using.

Re: [S2] MessageStoreInterceptor
Digging deeper into the struts2 architecture I can see now how the ActionErrors tag is quite a lightweight thing. I'd rather avoid setting up my own mechanism for handling session usage in an action superclass as I did with struts1 - I prefer the idea of an interceptor handling it, but as I implied in my first message, I also like the idea of having this done automatically with no further configuration in any action xml. So for the meantime, I'm going to tweak MessageStoreInterceptor for this purpose. What further scenarios do you see for putting things in the session for automated transfer to the next request? To my mind, error messages and informational messages are an important enough component in their own right not to be bundled up into a more generic mechanism. I avoid the use of the term 'flash scope'. That's the Spring Webflow term you are borrowing I guess. Abstracting away from the HTTP paradigm, as 'flash', 'conversation' and the bulk of Spring Webflow mechanisms do, is counter-productive in the long term unless you are creating a restricted, RAD-style framework where the user will never need to know details of the HTTP servlet mechanism. It constantly surprises me when I see colleagues who are meant to be webapp developers unable to figure out what is going on in the server-side between the browser and the business tier (I'm disrespecting Spring Webflow here!). I see the ActionErrors tag is linked in with the HTML templating mechanism too. For applications like the one I'm working on where there's no usage of the templating framework (it's set to 'simple'), it is fortuitous that the 'simple' template for the errors tag applies exactly the HTML that I need, although I feel uncomfortable for the future that it locks me in like that. I hope this comes across as constructive! Don Brown on 21/09/07 04:43, wrote: I agree it could be made easier. I'd like to see it combined with a flash scope-type interceptor so that more than just messages could be passed via the session automatically. As for your solution, you could implement the SessionAware interface and get the session map directly, then you could do whatever you want. Don On 9/21/07, Adam Hardy <[EMAIL PROTECTED]> wrote: From the javadocs, this interceptor seems to have a relatively complicated configuration that caters for situations over and above what I need relating to message and error caching when redirects are involved. A solution to simplify MessageStoreInterceptor would be where it puts the msgs and errors into the session on one call and automatically switches its state from STORE to RETRIEVE. On the next request after doing whatever RETRIEVE does, it could then automatically flip to STORE state. Would that work? Another solution would be if the messages and errors are stored in the session all the time and then removed once they have been displayed, e.g. by the actual actionmessages or actionerrors tag. Can I abandon the MessageStoreInterceptor then and somehow tell S2 to put the actionerrors straight into the session? Then I could extend the taglib to remove them when displaying them. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
