Should we use JSF?

I'm new to JSF.
Can anyone comment how flexible it is to use JSF ? Is it expandable to other Java technologies as well in future or it will tie us down to JSF environment?
Another thing is what is the tools that most of you use to develop using JSF? Are you using Java Studio Creator? Any issue of using this tool in terms of future expandability?
Please advise.
Thank you.

stew_mic,
I have a question for you since you use Java Studio Creator 2 (JSC2) before.
Anything that we drag and drop to the form, JSC2 will actually create the code for the component in the jsp right? This include the positioning of the component.
My question is:
1. Is it only JSC2 can be used to update this position (let say we wan to update visually) ? How do you update the layout previously?
2. I came across some resource on Internet that some JSF JSP page that I see does not contains the positioning information like what JSC2 is generating. They still have html codes and just that certain part of the JSP page contains some JSF scripting. How is this different from the one with JSC2?
Your advice in this is very very much appreciate. : )
Thank you.

Why should i use JSF rather than Struts?

What makes JSF useful than Struts? In my project I am using like
<h:commandButton action="#{loginbean.execute}" actionListener="#{loginbean.handleEvent}" ..../>
In the above commandButton as you can see that i am not exposing the beanName. However i am exposing the beanMethod which are execute and handleEvent. Is there any other way to hide the name of the method because
From what i understand is Presentation Layer should be shielded from whatever is going on in the backend. So, this doesn't do good right?
Please suggest.
How does Component and Renderers help. I am using encodeEnd() method in Renderer to render what the input or the output should look like. Do we need to switch to JSF from Struts just because of this... I don't see how and why components and renderers could help me..

You can rename your method to reflect what you want to see in the front end if you want. You can use JSFTemplating to use handlers which can be mapped to any name you want to see and do not have to match the method name of the java class (although I suspect this is the opposite direction from what you are suggesting you want).
EL in jsf (i.e. #{bean.login}) is meant to do the mapping in JSF pages rather than externalize this in a separate file and force the page developer to edit multiple files for simple tasks. Although in some cases navigation is broken out into a separate file (i.e. faces-config.xml file using the default NavigationHandler navigation rules), this can also be done inline. It's a different way of doing development and has its pros and cons (easier, but mixes up presentation and controller somewhat). That said... JSF is very flexible, it CAN externalize any of this information, it just requires you to provide a different ViewHandler information that allows you to enter the data the way you like to see it (imo, you won't realize any benefit from the separation, though -- I used to think it was worth doing but have changed my opinion).
So, this doesn't do good right?Perhaps in theory... but in practice, I don't think it really has a drawback. One caveat, I like how I implemented event handling in JSFTemplating as opposed to action/actionListener attributes which are not configurable and are more opaque than I prefer. My parameterized handlers allow for better code-reuse, but arguably mix up presentation and controller code even more (depending on how they're used).
Please suggest.
How does Component and Renderers help. I am using encodeEnd() method in Renderer to render what the input or the output should look like. Do we need to switch to JSF from Struts just because of this... I don't see how and why components and renderers could help me..The idea of a component helps tremendously as someone else can create a component for you and you can benefit from it. There are many great component sets available on the market (for free and for purchase). For example: Woodstock (which has drag/drop support inside NetBeans), RichFaces, IceFaces, Tomahawk, Scales, etc.
Renderers allow you to cleanly separate the presentation of a component with the data of the component. You can then switch out the presentation to support multiple markups (i.e. client devices). In addition, JSF's rich lifecycle provide logical places for certain types of operations to occur, the renderers participate in this so that they are performing their tasks at a well defined time. And finally, many different components may re-use the same renderer, or a single component may use one of several renderers. The separation of data and display (model and view) makes this very clean.
JSF is not Struts. If you expect it to be struts, you may be disappointed (or if you expect struts to be JSF, you'll be disappointed). JSF has a lot to offer (as does struts), you have to decide what is important to you and your organization. Some things to consider wrt to JSF: very strong vendor support; many large set of components to choose from; multiple standards-based tools to choose from; very flexible (most parts of the framework are pluggable); active growing development community; component-based model which encapsulates complexity for things like Ajax, pagination, and other things (often complicated in a non-component architecture); good integration with other frameworks.
I don't know if this makes your decision any easier, but hopefully it helps clarify how you should be viewing JSF & Struts.
Good luck!

Issues in using JSF UI:Tree tag

Hi,
I am trying to work with Tree Structure using JSF UI tags. In Studio Creator i just created a JSP page and designed a Tree with two nodes under it. This is what i have in the body of my jsp.
<ui:body binding="#{Page1.body1}" id="body1" style="-rave-layout: grid">
<ui:form binding="#{Page1.form1}" id="form1">
<ui:tree binding="#{Page1.tree1}" id="tree1" style="left: 48px; top: 48px; position: absolute" text="L3">
<ui:treeNode binding="#{Page1.treeNode1}" expanded="true" id="treeNode1" style="width: 408px" text="Tree Node 1">
<f:facet name="image">
<ui:image binding="#{Page1.image1}" icon="TREE_DOCUMENT" id="image1"/>
</f:facet>
</ui:treeNode>
<ui:treeNode binding="#{Page1.treeNode2}" expanded="true" id="treeNode2" text="Tree Node 2">
<f:facet name="image">
<ui:image binding="#{Page1.image2}" icon="TREE_DOCUMENT" id="image2"/>
</f:facet>
</ui:treeNode>
</ui:tree>
</ui:form>
</ui:body>
But when i am trying to launch the jsp page from browser i am getting the below exception.
com.sun.rave.web.ui.appbase.ApplicationException
Caused by: java.lang.NullPointerException at java.io.File.(File.java:194) at com.sun.rave.web.ui.renderer.template.xml.XMLLayoutDefinitionManager.getLayoutDefinition(XMLLayoutDefinitionManager.java:142) at com.sun.rave.web.ui.component.TemplateComponentBase.getLayoutDefinition(TemplateComponentBase.java:150) at com.sun.rave.web.ui.renderer.template.TemplateRenderer.encodeBegin(TemplateRenderer.java:73) at javax.faces.component.UIComponentBase.encodeBegin(UIComponentBase.java:683)
Any suggestion to solve this issue would be greatly helpful.

Now with Unified EL - JSTL and JSF tags are supposed to work on one page.
If you want to use Unified EL you need
1) A container that is built on Servlet 2.5 / JSP 2.1 , and example of such a container is Tomcat 6.x
2) Probably need to upgrade to JSTL 1.2 , and JSF 1.2
3) If you're upgrading the container to Servlet 2.5 then web.xml should conform to Servlet 2.5 version.
4) Use correct taglib URIs for JSTL 1.2 and JSF 1.2

Using JSF and IFRAMEs

I have a basic JSF app that takes some input, does a request and creates a table on output. What I need to do with it now is to have the query "page" and results "page" in two iframes on the same page. Before the query has been run the second iframe should just be blank (or with some default text). After the query that frame should be populated but the query frame needs to still be there. I've managed to do part of this. The "search" page and the "results" page are in separate iframes:
<%@ page session="true" %>
<html>
<head>
<title>Frames</title>
</head>
<body>
<table>
<tr>
    <td width="100%" colspan="2">
      <iframe title="Synonyms Search" src="search.jsf"
          width="800" height="200">
      Alternate search content...
      </iframe>
     </td>
</tr>
<tr>
<td width="100%">
    <iframe src="results.jsp" title="Results"
      width="800" height="800">
      Results....
    </iframe>
</td>
</tr>
</table>
</body>
</html>The reason this page is not using jsf tags is that the iframes will need to contain other pages that themselves are not jsf (mostly servlets) and I wasn't sure I could make that work. Currently the problem is that previously the search page had a QueryBean that the results page accessed to create it's table of results. Now in iframes the results.jsp frame just has a jsp processing exception and running the query does nothing. I'm new to JSF so I'm sure there's parts I'm missing, these do work if I pull them outside the frames and write navigation rules in the faces-context.xml file.
Thanks,
Sarah

Using JSF and JMS

Hello Suners,
I'm developing a web project using JSF for client side development and EJB for server side development. I need to inject a stateful session bean inside my managed bean in order to send the user entries in a message to a JMS queue which in turn give it to registered MDB for asynchronous requests handling. The problem is once the session bean is initialized from within the managed bean i have a null pointer exception for the QueueConnectionFactory and in turn gives a lifecycle exception for my jsf page. I don't know where i should use my session bean. any help will be deeply appreciated, here is the beans code :
SessionBean
@Stateful
public class StockSessionBean implements StockSession {
     @Resource(name = "jms/QueueConnectionFactory",mappedName = "queueConnectionFactory")
     private ConnectionFactory connectionFactory;
     @Resource(name = "StockHistoryQueue", mappedName = "stockHistoryQueue")
     private Destination stockQueue;
@Remove
private void sendUserOptions(UserOptions userOptions) {
          try {
               Connection connection = connectionFactory.createConnection();
               Session session = connection.createSession(false,
                         Session.AUTO_ACKNOWLEDGE);
               MessageProducer producer = session.createProducer(stockQueue);
               ObjectMessage message = session.createObjectMessage();
               message.setObject(userOptions);
               producer.send(message);
               producer.close();
               session.close();
               connection.close();
          } catch (Exception e) {
               e.printStackTrace();
}ManagedBean
@ManagedBean(name = "userInfo")
@SessionScoped
public class UserInfo {
@EJB
private StockSession stockSession
public doSubmit(ActionEvent e){
stockSession.setEmail(email);

Using jsf with struts

hi;
i am trying to understand the proper architecture when using jsf and struts together.
i think i understand the differences between the technologies . it seems to me that instead of justifying jsf there should be a focus on how the two technologies actually collaborate.
specifically, i would like to know or see examples of things like replacing the view portion of struts and plugging in the jsf framework instead or how to i replace the struts actions with jsf commands or maybe they are totally different things.
where can i get information like this?
thanks.

At present, i think the best thing to do is to look at the example provided with the struts-faces integration taglib. I don't know any documentation about it.

Portal Development using JSF & Struts

Can some one explain about the feasibility of developing portals using JSF and Struts? What are the advantages and disadvantages of doing so? Is it a right decision to develop portal servers using these?

Yes I am familiar with all those links. Let me break down scenario and ask specific questions.
Server version: Netweaver 7.0 (2004s) SP18
1. Created External Library DC (i.e. ebuslib)
         - added 3rd party JARS (e.g. hibernate, Spring)
         - created two public parts - one for compilation, one for assembly (deploy)
         - activated activity
2. Create J2EE Server Component - Library DC (i.e. ebuslib2)
          - added "ebuslib" assembly PP as Used DC (build only)
3. Built "ebuslib2"
          - can see jars in the resulting sda file.
          - activated activity
          - confirmed on J2EE engine deployed library containing the jars.
Scenarios
A. EP Project DC
           - needs access to 3rd party jars
           - QUESTION: What do I need to reference? The External Library DC or the J2EE Server Component Library DC?
                         - I read that you should reference the J2EE Server Component BUT the jars are not available in the PP of that DC.
                         - One developer one talked to referenced the compilation PP of the External Library DC (i.e. "ebuslib").
                                 - this seemed to work but then I wondered how the project finds the JAR at runtime?
QUESTION: Does SAP load all the classes that have been deployed via the J2EE Server Component Library DC method and hence those JARs are globally available at runtime hence no need to reference them during development except for compilation? What if > 1 J2EE library contain the same jar or same API but different versions (e.g. Hibernate 2 vs 3).
Thanks for any clarifications. I want to understand the underlying technology and how it works. I have seen alot of information out there but some of it is confusing and conflicting.

Using JSF in search engine.

Hi,
I am implementing a search engine. I want to use jsf for for the UI part. I have few queries in this regard.
- Has anybody used jsf for the same?
- Since the search result may contain any number of result, then it is not good to first load all the results into a List object and then do the pagination.
Cheers...

Hi Tom,
I am currently involved in developing a web front end for our book search engine. We used JSF and though we had some issues initially, we are pretty happy with the results. You can check it out at http://books.infact.com.
As for pagenation, the fetching of results (including number of results retrived each time, total count of results etc) should be handled by the back end of your search engine, in my opinion. The JSF part should communicate with the backend to get the number of results it needs to display. Hope that helps.

Deploy web applications using JSF 1.2 or JSF 2.0 to WLS 10.3.5

Hello,
We have ADF web applications developed with JDeveloper 11.1.1 (using JSF 1.2 and JSTL 1.1)
deployed on WebLogic server 10.3.4.
Our department plans to :
1. upgrade to WebLogic server 10.3.5 with the ADF Runtime 11.1.2.0.
and
2. develop new ADF web applications using JDeveloper 11.1.2 (using JSF 2.0 and JSTL 1.2)
My 2 questions are the following:
1. Can we deploy all JSF 1.2, JSF 2.0, JSTL 1.1, and JSTL1.2 WAR files on the
WebLogic server 10.3.5 with the ADF Run-time 11.1.2.0.
2. Can we deploy existing ADF web applications developed with JDeveloper 11.1.1 (using JSF 1.2 ,JSTL 1.1)
and new ADF web applications using JDeveloper 11.1.2 (using JSF 2.0 and JSTL 1.2) to the WebLogic server 10.3.5 with the ADF Runtime 11.1.2.0
Any insights will be greatly appreciated.
Thanks

1) That should work
2) old adf app (developed with jdve 11.1.1.x.0) need to be migrated to jdev 11.1.2
You can also check out my blog entry about the jdev wls versions here http://tompeez.wordpress.com/2011/09/14/jdeveloper-versions-vs-weblogic-server-versions

What type of hard disk should I use if I want to use it on mac and windows?

Hey Forum,
I am using windows xp on my macbook (snow leopard). I came across some dealers who say that there are hard disks for mac only and for both mac and windows. So, I wanted to buy a hard disk so that I can use it both on mac and windows xp, so what type of hard disk should I use? Must I partition into 2?
or are there any harddisk in the market which is compatible for both mac and windows xp without screwing up the format(NTFS/Mac OS X Journaled)? Pls look into this matter and help me with it.
All of your replies and suggestions is much appreciated.
Thank you.

I feel I must move beyond iMovie, what program should I use ?

I have been happily using iMovie and iDVD from versions 1 through 6. iMovie 08 was so bad that Apple made iMovie 06 available as a free download for buyers of iMovie 08. The newer iMovies were better, but they seemed “dumbed down” (even for me). Now, I am shocked and horrified to learn that the latest iMovie does not even set chapter markers!
So, I have continued to use iMovie 06 and iDVD 08 (they seem to work fine under OS 10.9.4).   iMovie 06 is now 8 years old! I feel compelled to move forward. A lot of my work is DV.    In the past, most of my source material came out of S-Video.   I used a Canopus ADVC300 analog-to-digital converter that gave good results.   Going forward, I will have more video utilizing Component Video, or HDMI.
I am looking into 2 possibilities, Adobe Premiere elements 12, or.........Final Cut Pro X.
The final result of my work is almost always a DVD.   It is hard for me to move from iMovie and iDVD. I never read the manuals for either program, yet, I was able to produce DVDs with nice menus and overall quality close to Hollywood.
It looks like Final Cut Pro X 'can' make a DVD directly without other software. However, from what I have seen on YouTube the result is primitive compared to what iDVD was doing 10 years ago.
Adobe Premiere elements 12 can make nice DVDs and Blu-ray's directly. I have no problem with using a separate program to make DVDs but I haven't got a clue how to do that with Final Cut Pro X.   I suppose I can still use iDVD, but now I'm back to using discontinued software.
I do not need any of the high-powered affects capability that Final Cut Pro X possesses. My “movie-making” is mostly confined to simple editing (the old iMovie 06 did all I needed).
Frankly, one motivation for choosing Final Cut Pro X, is the excellent, compassionate and understanding support that the kind people on this very forum provide. So, what program should I use?

to turn perspective for a second by 180°:
Why do you want to switch to a new editor anyhow?
• iM-a never did discs - that was iDVDs job = no big change in your workflow
• iDVD is still working, and aside obsolete, complex and $$$$ DVDSP (part of obsolete FC/p) or Encore (part of Adobes CC rent package) your only option left to create disks on MacOS is indeed iDVD (...ok, there's Toast and Burn and some weird 'shareware'-stuff...)..
• iMovie-b supports the new HDef formats (AVCHD) - you mentioned converters and DVDs = no HDef in use, in your habitat, correct?
• if you don't need FCPX' bling-bling (I can't imagine that ) - why not using FCPX-lite = iMovie? 15$ ...
• chapters could be done in iDVD - just to mention that ............
• AP and FCPX are following very different concepts in usage - my personal preference is 200% on FCPX, … I was one of the loudest nay-sayers, when iM08 araised, meanwhile, FCPX is my dream!! AP (tested it) is way too complex, crowded, 'optionalized' and did I mention 'complex' for me. A bit like Windows vs. MacOS: 'everything goes' (incl. getting lost) vs. 'convenience' (incl. restrictions) ... After 2y of practice, I'm editing my weekly hobby-projects with 6-cam-Multicam, incl. tons of custom graphics, slow-mow, effects (soccer games) in less than 2h ... awesome!
summary:
• why switching?
• use iMovie10 + iDVD
• Premiere (or Premiere Elements!) and FCPX are both avail as fee trial ... test it - but you need iDVD anyhow
• 'disks' is a dwindling niché, for years!- consider to switch to 'other' distribution options
... what are 'chapters' anyhow??... (kid din'!)

Which C# Adobe library should I use to open a PDF in Acrobat Reader 9, 10, and 11?

Hi, all.
I have a Visual Studio C# application that writes an Adobe PDF using iText. Does anyone know how to programmatically open the PDF on client's computer and ensure it works for Adobe Reader 9, 10, and 11?
-I have Adobe Reader XI on my machine and "Adobe Pdf Reader" is NOT showing up in my COM references. This is the library that I've heard people use for this.
-The "Adobe Reader File Preview Type Library" is showing up there, but does not add to my project because of the following error message: "A reference to 'Adobe Reader File Preview Type Library' could not be added. Could not register the ActiveX type library....adoberfp.dll'." But I haven't persued this further becuase I'm not even convinced I should be using this library, which brings me to my next point:
-Please don't tell me to go read the Adobe SDK spec. In searching for this answer, I found posts on here with people asking this question and getting not great answers, or half-*** answers to go read the Adobe SDK spec. I have the Adobe SDK spec, it's terrible. The example source code is laughably poor and reads like it was written by someone with bad english, with poor naming, commenting, and documentation, and there is no separate document that explains what the source code does. I think the reason people say this is because they haven't read it themselves and they don't know the answer and hope to deal with the question by handwaving. Sorry for the rant if you weren't going to do that!
Thanks in advance, if anyone knows.

It will be from a client-side application, and I will be reviewing this further and get back on it. At this time my assembly isn't the correct type of 32-bit, which may be a deal-breaker. But downgrading it to 32-bit, I wasn't able to find or include the appropriate library for AXAcroPDF.
Just a word about my trying to read the SDK documentation. The documentation folder has 5 items, a folder called "Javascript", an html file caled "Acrobat_11_SDK_Help_Shortcut.html", a zip file called "...HTMLHelp.zip," pdf_reference.pdf, and U3DElements.pdf. I've never heard of U3DElements, so surely that isn't meant for me. The pdf_reference.pdf, when opened, has three PDF links to two supplements to ISO 32000-1 and a document titled Document management. These describe the PDF spec, so that's not for me. So I must have to use the HTML documentation shortcut. I open it, and my browser says the redirect URL can't be found. Ah, may be that stuff in the ZIP file it's referencing. After unzipping it, you have to move the file around so that it actually references the right index.html inside the unzipped folders, and then even after this it loads up as two blank frames in my browser. I will look into why the links are all dead, but holy lord, this is just not very helpful at all.
Thanks for your help, Test Screen Name.

Should we use JSF?
