We want to migrate our project from IBM WebSphere 6.1 to Tomcat 6, but in our JSP-JSF UI pages we have extensively used below IBM JSF tags.
ScriptCollector
PanelRowCaregory
PagerWeb
OutPutSelections
InputRowSelect
InputHelperDatePicker
InputHelperAssist
ConvertMask
And to replace above tags, we are trying to find the equivalent tags from Sun JSF or any other open source libraries, but we didn't find any equivalent tags.
I wanted to know whether any body has already worked on this kind of migration project, if yes can you please share the equivalent tags?
or if you solved it differently even that info also will be useful.
Thanks in Advance.
There's no standard JSF equivalent for the <hx:scriptCollector> (although the JSF 2.0 <h:head> comes close). The <hx:scriptCollector> is only required by those IBM-specific <hx:xxx> components. It's designed to collect all JavaScript files required by those <hx:xxx> components and then render the desired <script> tag(s) without potential duplicates when multiple components require the same JS files. It's not required by any standard JSF component.
In other words, just get rid of it without replacement.
As to other tags, just check the available standard components in tag documentation or Java EE tutorial. If none is available, just pick a component library like PrimeFaces or RichFaces. If you still can't figure out, ask an individual question for the particular tag.

I'm busy getting this red-line when trying to use <rich:notifyMessage>. I'm used to primefaces but for this project richfaces is inevitable, hence i'm quite a novice here. I'm using richfaces 3.3.4 final and all required jars are included. What could I be missing? Is there a perfect alternative for a notification message pop-up apart from <rich:message> or <rich:messages>? I'd really appreciate a working example too. Thanks in advance.
I have used Bootstrap while development of Web Application. Now I have started learning of BootsFaces. While learning very first question pop up in my mind is
What is Exactly difference between Bootstrap and BootsFaces? and
what are their pros and cons over each other?
I searched for these answers but there wasn't any answer which make my doubt clear. Please help me for these questions.
BootsFaces is a JSF component library which generates HTML that uses Bootstrap. BootsFaces allows you to easily work with Bootstrap in a JSF application. Comparing them would be more or less the same as comparing red paint to a red painted board.
Some info from the BootsFaces showcase on this subject, specifically on layouting:
Why BootsFaces? Why not using Bootstrap natively?
BootsFaces takes full advantage of Bootstrap's Grid system while maintaining the benefits of being a JSF framework. Actually, we believe it's more concise and more expressive than programming Bootstrap natively. Convince yourself: inspect the source code of the demo in your browser's source code view. After reformatting, the form is 81 lines. The JSF source is is 45 lines.
BootsFaces being a JSF framework means that you can leverage Bootstrap's layout feature using - for example - the JSF templating system and JSF's conditional rendering to achieve and maintain very complex layouts without much effort.
This website is an example itself: it uses a page template with ui:insert and ui:include and the pages are ui:compositions.

What is the need of JSF, when UI can be achieved with JavaScript libraries such as jQuery and AngularJS
We're trying to use the <f:view contracts="xxx" /> feature from JSF 2.2, with many simultaneous contracts, as "contract1,contract2".
In our contract1, we have a file style1.css, and in our contract2, a style2.css. We include both in our views through <h:outputStylesheet /> tags.
If I only use contracts="contract1" in the view, JSF logs than style2.css is missing, which is logical.
If I use contracts="contract1,contract2", JSF imports both style1.css and style2.css, but with a faulty url (it uses &con=contract1 instead of &con=contract2 to get the resource).
Is it a bug? Is it normal? I can't find any documentation about the use of many simultaneous contracts.
That's normal behaviour, as I've found in the Apress Pro JSF and HTML 5 text book. An excerpt:
It's possible to map multiple contracts to a single mapping. In that case, it will go through each contract sequentially to look for the required templates. Once a template has been found, it will stop processing other templates.
As to why it's allowed, if all it's going to do is pick the first suitable option, I'm with you on the fact that it may be pointless after all.

I'm on the hunt for some more reading on JSF's HTML5 tag H5. I saw IBM's JSF 2 fu articles on it , but haven't really seen much else except presentations and slide shows on 'the promises of html5' and such.
Can anyone suggest some recommended technical reading ?
I'll bet that you're talking about this article. The h5 taglib just points to composite components which wraps some HTML5 specific elements. Composite components are just Facelet files which can be declared and used as a single JSF component in other pages. Even more, the full source code is posted in public in chapter "A JSF 2 HTML5 canvas component" of the article. You just have to copypaste it into your project to get it to run. It's not some component library like RichFaces/PrimeFaces or whatever which you have to download, install and configure first.
JSF doesn't care if the output is XHTML or HTML5. Both are equally valid as long as you adhere the XML syntax (i.e. the document must always be well-formed). You can perfectly inline HTML5 specific tags in JSF pages/components. Your only concern is the browser support.
If your concrete problem is more the lack in understanding of the purpose of composite components and how they work, then I'd suggest to get yourself through the appropriate sections of the Java EE 6 tutorial.
Java EE 6 tutorial - Chapter 5 - Facelets - Composite Components
Java EE 6 tutorial - Chapter 13 - Advanced Composite Components

Closed 5 years ago.
I'm using RichFaces per a client requirement, but the markup it (and the stock JSF controls) generates is an awful mess of nested tables. Are there any control libraries out there that generate nicer markup? AJAX support is a huge plus!
There is ICEFaces which provides more semantic support than RichFaces .Also you can try Nitobi suite which also provides similar kinda solution.If you are not satisfied with any of these I suggest try to write your own part extending the Sun faces
Short answer: No I have not yet found one.
Your options include using less complicated controls and know what html the standard controls emit. Thing like h:panelGrid render as a table. There is nothing stopping you writing your own rendering family which produces more standards compliment html, but this would be a big time investment.
As for using RichFaces if you stick more to the a4j: namespace of tags you will still be getting the cross browser ajax with out all the mark up you don't like.
