JSF vs Struts - both with tiles

I'm running in the problem migrating from Struts to JSF.
In struts I have the following fragments:
jsp (actualy in the resulting html):
log4j
struts-config:
<forward name="log4j-page" path="doc.log4j"/>
tiles-config:
<definition name="doc.log4j" extends="doc.mainLayout">
<put name="body" value="/WEB-INF/html/examples/log4j.jsp" />
</definition>
As a result this links the anchor on jsp page to my 'mainLayout' with 'body' replaced with ...log4j.jsp.
I found no way to replicate this link in JSF.
I tried <h:commandLink...> with a certain action. It seems that in faces-config fragment: <to-view-id>foo</to-view-id> JSF framework is always looking for foo.jsp.
I'm wondering if there is any way of pointing in the faces-config to the definition name in tiles-config.

Hello,
There are differences between the two and some similarity. A couple of major differences I have noticed is that in using JSF you have much better control over user events and page response to user actions. The reason why is because JSF uses an event-driven model (e.g., you can write ActionListeners, EventHandlers, and event Dispatchers) to respond to any user activity on the page. Also JSF tags are far more programmer-friendly (in my opinion) than Struts. Another thing I would keep in mind (especially if you are a programmer) is that Craig Mc C. was the developer of both (with help from others); How often have you said to yourself after completing a project "given what I know now, If I started over from scratch I would make it so much better by doing... instead of ..."? Having used Struts for both large and small projects in the past, I really see JSF as a "simpler, leaner, smarter, more intuitive Struts than Struts". I think its much easier to learn and maintain than Struts (of course that depends on your coding style), and here is a key point: JSF will soon have visual drag and drop coding editors that both IBM and Sun will provide, and hopefully an open source version will appear as well. Visual design and development is not for everyone but it certainly has its place (in my opinion).
I suggest you try create a simple app that includes all of the usual form components (checkboxes, lists, radiobuttons, textareas, submit buttons, etc. though not necessarily all on one page) using JSF and then Struts (or vise versa) then you can have a feel for how simple or complex it is using either for the usual web UI development assignment.
Cheer,

JSF Actions and ActionListeners with Tiles and forms

I�m having a problem trying to use the Tiles functionality in Struts 1.1 with JSF and was wondering if anyone could help me.
I have defined a very simple header, menu, content Tile that doesn�t involve nesting of tiles (ExampleTile_content1Level.jsp).
I have 3 JSP pages, the first testHarness.jsp is NOT built using Tiles and is just used to load some test data into a session scoped bean using an actionListener and then forward to a Tile generated page (ExampleTile3.jsp) using a hard-coded action �applicationSummary� when a commandLink is pressed. This works fine for both the action and actionListener.
ExampleTile3.jsp contains another commandLink that is meant to forward to another tile ExampleTile2.jsp. This also works until I try to add the <h:form> � </h:form> tag around the outside of the <h:panelGrid> tags in ExampleContent1.jsp when the action and actionListener then fail to fire and I get an �Error on Page� message in Explorer the detail of which says �Error �com_sun_rave_web_ui_appbase_renderer_CommandLinkRendererer� is null or not an object�.
However I need a form so that I can bind UI controls to data from the bean stored in the session scope. This is only a problem when I use Tiles to define the pages. Does anyone know what I am doing wrong?
Any help would be much appreciated.

Hi everybody,
I want to overload a method so it can take either 2 Actions, 2 ActionListeners, or one of each. The issue with this is that I'd have to make 4 overloaded signatures and almost identical methods, like this:
method( action, action )
method( action, listener )
method( listener, action )
method( listener, listener )
Well, if you want to support that then you are just going to have to do suffer through it, the only shortcut I can recommend is that your method(action, listener) and method(listener, action) are the same so you only have to implement 1 and just use the other as a entry point to call the one you wish to contain the code.

Is in JSF (with Creator) a tehnologie similar with Tiles?

Hy! I'm new and I want to ask: is in JSF a tehnologie similar with Tiles? How can I make my jsf pages to have some header and footer? Of course, in Creator.
Thank you very much.

In general, by design, JSF is a much more flexible framework as JSF is built with integration and extensibility in mind. JSF isn't easier than Struts when developing by hand, but using Sun Java Studio Creator can make it much much easier and greatly increase your productivity.
Take a look at the Craig McClanahan's Weblog (He was the original creator of the Struts Framework, and was the co-specification lead for JavaServer Faces (JSF) 1.0 )
http://blogs.sun.com/roller/page/craigmcc/20040927#struts_or_jsf_struts_and
A good place to learn more about JSF is JSF Central .
http://jsfcentral.com/
As for your second question, you could use 'Page Fragment Box'. Check the online help for "Page Fragment Box".
'This component enables you to include a page fragment in a page. A page fragment is a separate, reusable part of a page that can be included in any number of pages. For example, you might want to put a common a visual element like a header graphic in a page fragment and then include it in all the pages in an application......'
Hope that helps.

JSF 1.2 with tiles

it opens register.jsp as new page instead of opening it into tile.
Please helpmeout in knowing where I am wrong and let me know how to open next page in tile because welcome page is opening very well in tile but when I click for next page whose definition is defined in tiles-def.xml it doesnot open in tile
Thanks

Still strugling with jsf1.2+tiles

JSF versus Struts

Hi, I'm researching JSF and Struts and they look identical. Seems like the developers of JSF just took Struts and changed the wording. What I mean is:
struts-config.xml became faces-config.xml
ActionMappings and Actions became NavigationCases and NavigationRules
FormBeans became ManagedBeans
MessageResources became MessageBundle
ActionServlet became FacesServlet (in web.xml)
Both have validators and converters.
So am i missing something?
Also, are there any performance benchmarks that JSF/Struts add to response times?
Thanks,
Mike

I tried out JSF on some small projects and it worked out OK. However, when I tried using JSF on a major project, I got burned. I ended up converting all my JSF work to Struts.
Before I say what I didn't like about JSF, let me say what I do like. I like how easy it was to associate a button or a link with a method. I like how easy it is to validate input. I liked how easy it is to show or hide components based on boolean expressions. When it comes to these things, I was able to develop code a bit faster with JSF than with Struts.
However, the negatives were so great that I eventually abandon JSF...
(1) If you have a graphic artist that creates prototypes using static HTML, converting those prototypes to actual working pages is MUCH easier with Struts tags than with JSF tags. The problem with JSF tags is that you cannot always mix JSF with standard HTML. This is especially true if you are using Tiles. You may end up having to completely rewrite the static HTML tags to their JSF equivalent. This is simply more trouble than it is worth. (There are JSF tag libraries available that act like standard HTML tags, but I found the tags to be buggy and the code simply very cluttered.)
(2) Creating tables much more complicated that a textbook example can end up being more trouble than it's worth. For example, if you want to create a table where some rows are sub-headers (rows that span all columns and contain a sub-title), then you will end up having to create a custom renderer and a custom tag library. There is a learning curve involved with this. (Even if you are an expert in writing these, you still have extra code that needs to be written.) With Struts, the same thing can be accomplished with some simple logic tags.
(3) Sometimes, all I really wanted was to iterate through a list of values. JSF does not come with a simple iterate tag. You can loop through your data with a JSTL tag or you can use a datatable or you can create your own tags, but that is extra work. Even if you choose to do any of these, you still cannot reliably mix standard HTML tags with JSF tags.
(4) Everything in JSF is submitted as a POST. Sometimes, I really needed to use a GET. You can use GETs in JSF, but I found using them to be less than straightforward.
My advise: If you are building a web app, use a framework that plays well with HTML. (Ultimately, your web app is generating HTML anyway.) If you are building a stand-alone app, use Swing or some language other than Java. If you need your code to run as both, then JSF might be a solution.
I really wanted JSF to work for me, but I ended up being disappointed.

Integrating ADF with Tiles - Facing some problem with ViewHandler

Hi,
I am trying to integrate ADF with Tiles. I am able to use tiles and display one or more JSF files using ADF components on a single tile using this thread, ADF Faces Access Denied But the issue is, the functionality of the pages are not getting included, for example, I have an action on click of a command link in one of the tiles, which is not working, its not even refreshing the page. When I tried using plain jsp:include, it works.
I doubt its b'coz of Tiles - committing the response and forwarding the page, rather than including the page. Does anybody tried on this and have some work around?

JSF and Struts - differences and integration goal.

I am a newbie J2EE developer and I am not clear about main differences between JSF and Struts also I saw couple of articles describing integration between JSF and Struts. Could someone give me an explanation, what the main conceptual differences between those technologies and what's the goal of integration both of them?

I describe the main differences between JSF and Struts in this sample Chapter from my JSF book:

JSF or Struts

Hi,
We have a web application designed using MVC framework. Besides a web view, we now need to support mobile users using WML.
We are considering JSF and struts (customising struts to handle WML client).
I have read that JSF supports disparate clients efficiently using RenderKits.
Can anyone suggest whether JSF has an easy to use WML RenderKit. How does a renderkit work? Is there any good documentation online?
Is there a Renderkit for WML readily avaialble or will I have to make one? I know there was a link posted in one of the questions in this forum, but it is a dead link.
Thanks in advance,
Harsha

JSF is better than Sturts. ("Until now there is no sucess story on JSF.")
Becoz, Struts inventor has been hired by SunMicroSystems to work with JSF. The same guy mentioned in an interview, that struts developement will be stopped in future.
Also..,
Until now there is no sucess story on JSF. Only time can decide which is best.
My suggestion is, better spend your time in learning more jsp and servlets specifications, XML/XSLT, JMS, Webservices rather JSF/Struts.
All these frameworks like JSF/Sturts will depends on your project requirement. There is a nice book and online document in this website about design patterns. Read those things if you have time. You will get good idea.
Well.., this is all my personal opinions.

Struts validation with BC4J

We're developing an ADF/Struts app.
We started off with entity object level validation. However, we'd like nice formatable messages so decided to move towards Struts form beans and perform validation there.
Firstly, was this the right thing to do or can we place and format entity object validation errors however we like?
If we did make the right choice we aren't sure how ADF bindings and form beans interact and whether they should be used together.
We ask because of the following:
If we add a getFirstName field onto the form bean, and call the field in the JSP firstName (lower case 'f') then all is well and the form bean operates as expected with no errors.
However, if the field on the JSP is called FirstName (capital 'F') then the getter method is not found:
"No getter method for property FirstName of bean org.apache.struts.taglib.html.BEAN"
ADF bindings give the JSP properties upper case first-letter names by default. We can of course go and rename all of the bindings - but that's time consuming and as nobody has complained of something similar in the forums, we get the impression that we're doing something wrong or that they are rarely used together.
Any help appreciated.
Ben

The general rule with validation is never to rely on the UI generation layer to validate your data.
It's reasonable to place validation there, but you should back it up with validation on the EO as well.
If you want to mix Struts validators with ADF bindings then you're best using the Struts Validator framework and the oracle.adf.controller.v2.struts.forms.BindingContainerValidationForm as the type of the Form Bean for that page. That way you can use both ADF bindings and declaritive validations using the validator XML definitions

You're wanting to get back into writing web applications?
Web services?
1 - If you worked with struts before, I'd probably continue with that line. Or at least start there.
2 - I'd say Hibernate, but then I don't know that much about the others ;-)
3 - Java1.5.
I would also recommend you catch up with the changes between JSP1.2 and JSP2.0, particularly regarding JSTL and EL.
For learning JSTL, you can't past go the JSTL spec. It is quite readable, and an excellent reference. http://java.sun.com/products/jsp/jstl/reference/api/index.html

Link for BC4J Struts-JSP and Tiles

Hi,
I have a JSP-Struts application. By the default generation, JDeveloper build a main.html Page. This page have many Frames and one Frame is "navFrame". On this frame I have a link for a JSP Page : Browse. The call is OK. No Problems.
No I have another Page with Tiles :
<template:insert page="IMDLayout.jsp" flush="true">
<template:put name="title" value="Invoices Interface" />
<template:put name="header" value="/tiles/common/header.jsp" />
<template:put name="footer" value="/tiles/common/footer.jsp" />
<template:put name="menu" value="/tiles/common/menu.jsp" />
<template:put name="body" value="VInvoiceUsersView1_Browse.do" />
</template:insert>
The "body" Tiles call the same JSP Page as the link on the "navFrame", but now I have the following error :
[ServletException in:VInvoiceUsersView1_Browse.do] Response has already been committed'
Why ?
Please help me, I need a solution. Does somebody use BC4J/Struts/Tiles ? Any Experience ? Problem ?
Thanks

Should I bother with SAFARI?

I recently got this iBook with SAFARI installed so I've been trying it out. Up til now its been Explorer which I've had no real complaints about despite many views to the contrary.
So far I'm sadly unimpressed, nay peeved at how badly it works/doesn't. I've yet to scan thru the threads on this topic and without getting into my specific complaints at this point, I'll listen keenly to any general advice re. using Safari, staying with Explorer, trying some other browser. I have given Firefox a bit of a look see.
I'm a low-demand user--text, small graphics, minimal gaming, iTunes audio file-sharing.

Oh the discusion god is with me today. Look what popped up: a two-page "safari-slow browsing" thread dating back a couple months. So I'm not alone in this am I?
So is this a little Apple secret nobody wants to 'fess up to or what?
I've already gleaned Camino and iCab recommendations thru some other threads.
And I've been beginning to suspect 3rd party anti-viral programs as I did adopt a more cautious (but uninformed) approach and add Norton Antivirus v. 9.0 concurrent with upgrading to Panther and trying out Safari. There seems to be an old Virex program lurking somewhere too as its icon pops up at start-up but being fairly novice at these things I haven't ventured into removing it. I'll ask another thread but any advice here is welcome. Can I just drag the file/folder to Trash and dump?
Advice re. anti-virus requirements is also appreciated and I'll get another thread on this too.
Still 'Internet Exploder' (as a new discussion friend so charmingly calls it) beats Safari and Firefox hands down for loading pages and must surely be negotiating with the same anti-viral programs. Please keep in mind I'm operating at a fairly low-performance level both in terms of my machines and use needs. So we're talking what takes
several seconds (2-10 usually) in IE takes 5-20 secs in Safari and Firefox. I'm a patient guy and don't mind a bit of a wait but its the stupid stuff like crashing on Apple sites like this one that really annoy me.
"So I don't have enough experience to list too many
for instances."
The other slow Safari thread (you can see current posting today) sites lots of examples that reflect my neophyte experience so it really does bring me back to my first question:
Should I really bother with Safari?

Migrate from JSF to Struts?

Hi
I have seen some threads in this form regarding migration from Struts to JSF. Most of the posters back then (1999-2003) suggested starting with Struts and then migrating to JSF for production.
Now I have one year of experience with Struts in a Tomcat environment and practically no experience with JSF. My current job involves maintaining JSF code. The boss thinks migrating to Struts would make us independent of the company to whom the JSF project was outsourced.
I would like to know your opinion on migrating from JSF to Struts. How hard is it? Our architecture has Views, View Helpers, Business Context objects, Business Delegate objects, Business Processor objects, DAO (DB2, AS/400), DTO, etc. They seem rich enough semantically when compared with Struts that groups all these under MVC, even though they are complex to manage (job security :).
I'd appreciate your feedback.
Thanks
Murthy

To quote Ron Burdundy, "That doesn't even make any sense!" :) Seriously, though (and I admit a huge bias), that seems like a huge step backward. It seems the logic is this: "We outsourced the development of this system to someone else, and now we're left either maintaining it ourselves or paying them to do it, but, if we rewrite it with $FRAMEWORK, we'll be free of them." Is that right? How is maintaining a Struts app different (frameworks aside) from maintaining a JSF app? This is probably obvious, but that's a step I would neither take nor suggest. :)

My iphone 4s and ipad 2 both with 7.0.4 update will no longer connect to wifi but non-mac lap top has no issues

my iphone 4s and ipad2 both with 7.0.4 update will no longer connect to wifi.
About three days ago the ability to connect came and went and the connection never lasted more than 10-15 minutes; it has not been able to connect since last night. I do not think it's my wifi router as non-mac lap top has no issues. I have seem many similar questions posted.

Reboot your router by removing all power from it for about 15 seconds. Also, if your router still has its default SSID (such as LINKSYS, DLINK, NETGEAR, etc) change the SSID to something unique. Note that all other devices on your network will have to be reconnected if you change the name, but if the name is still the default that is most likely your problem.
If the SSID is not the default then the reboot should fix it.
