How to load a class dynamically (via reflection) in a jsf-component

Hi all,
I am writing my own jsf component and I would like to do it generically. Therefore I have an attribute, where the developer can pass a fully qualified classname, which I want to use to instantiate. But I have a Problem with the classloaders, everytime I get a ClassNotFound-Exception during debugging.
Does anybody know how it is possible, to to get the most parent classloader?
Currently I am even not able to load a class, which is in the same package like all other compontent-classes.
Thank you very much in advance
Thomas

Within web applications, I believe it is recommended to use Thread.getContextClassLoader(). Keep in mind that web applications require different classloader semantics than regular Java applications. The class loader which gets resources from the WAR is favored over others, even when this violates the normal class loading conventions.

How to add properties to a custom JSF component?

Hello, everybody!
I've just developed my first custom JSF component. It's a data pager and it is working pretty well. But now I want to be able to use some of it attributes in my backing beans at runtime. I mean, I want to bind it to component in the JSF page. It already has a binding attribute in the tld file, but I want to be able to accesss two values that the renderer of my custom component calculate inside it, which would relieve me from calculating these values manually in the backing beans. So, I would like to know how to make these values external to the component.
By now this is my custom pager class:
import javax.faces.component.UICommand;
public class UIPaginadorDados extends UICommand
}You can see that it has no logic because all the logic is in the renderer class:
import javax.faces.render.Renderer;
public class PaginadorDadosRenderer extends Renderer
// logic here
}As I said I want to be able to do the following in my backing beans:
private UIPaginadorDados pager = new UIPaginadorDados();
// and later...
pager.getCurrentPage();
pager.getPageCount();In the JSF page:
// I already can do this, because I have a binding attribute
<urca:paginadorDados binding="#{backingBean.pager}" />I suppose that I'll have to create the properties getCurrentPage() and getPageCount() in the component class, UIPaginadorDados, but I don't know how to get the values to the properties from the renderer class. I don't even know if this is how I should do it.
So I would appreciate a lot your help about this subject.
Thank you.

How can I include a javaScript files from within jsf component

Is there any way using which I can include javascript files from my jsf component. Because otherwise I have to write all the javascript commands using writer.write which is very tedious rather than this I just want to include the javascript file which contains all the functions required. Also I want that this file should be included only once irrespective of the number of components included.
Thanx in advance

This doesn't depend on JSF. You need to include a script tag, like:
<script src="/path/script.js"
language="JavaScript" type="text/javascript"></script>
If you want to include this only once, make a file included into every page, into which you can put other resources to be included along with this script.

How to make Javascript access standard JSF component

Hello all,
I'm in need of a proper javascript code that access standard jsf component.
Like we do for html tags;
if( el.tagName.toLowerCase() != 'select')
I need to do the same thing for a jsf tag i.e; <h:selectOneMenu>. How to make javascript access <h:selectOneMenu> like it does with <select> tag ? Please let me know asap. Extremely sorry if the question is kind of stupid....cause I'm a beginner for JSF environment.
Any sort of help, suggestion or advice would highly be appreciated.
Thanks in advance.

Ummmm, I may be off the beaten path, but by the time your javascript is called the h:selectOneMenu would be a select tag within the dom. You should be able to reference that tag as you normally would.

JSF component inside HTML table -- not rendering properly

I have a HTML table like the one below. In one of those columns (td) I have a JSF component. When I run the app, the JSF component (even if its a simple inputText or panelGrid or panelGroup) is not getting inside the td. Instead, it forms a seperate table after this td.
Code I have:
<table border="0" cellpadding="0" cellspacing="0">
<tbody>
<tr>
<td>... ..MULTIPLE Td's here - Deleted for simplicity </td>
<td class="topNav">
Blog Directory
</td>
<td>
<img src="./images/top_button_right.gif"/>
</td>
<td class="topNav">
<f:panelGroup>
<h:inputText value="Username"/>
<h:inputSecret value="Password"/>
</f:panelGroup>
</td>
</tr>
</tbody>
</table>
What I expected:
username, passwd field inside the top level HTML table.
What comes: (as a result of running thsi JSF page )
<table> -- Original table
<td> </td> -- -TD that had the inputText - comes empty here
</table>
<table>
<tbody>
<tr>
<td><input type="text" name="_id1:header:EasyHeader:_id4" value="Username" /><input type="password" name="_id1:header:EasyHeader:_id5" value="" /></td>
</tr>
<tr>
<td><table>
I am a newbie to JSF & due to the complexity of the layout & page, I m unable to get rid of the HTML tags totally.
Thanks in advance.
Ganesh

Found the solution to the problem.
wrapped the entire HTML page till the JSF component ( panelGrid) under <f:verbatim>.
something like this
<f:verbatim>
<table>
<tr> <td>...</td>
<td>
</f:verbatim>
<h:panelGrid> ... </h:panelGrid>
<f:verbatim>
</td>
</table>
</f:verbatim>

Can i use one JSF component's value for other component in the same page.

Can i use one JSF component's value for other component in the same page.
For example
I have a <h:selectBooleanCheckbox id="myChk"> in my jsf page, i want to access its value for another component like:
<h:commandButton disabled="#{myChk.checked}" action="myAction" value="myValue" />
** "myChk.checked" >> I am just asuming "checked" property is available...

Bind the checkbox to a UIInput myChk property. Then you can reference this property from the page, e.g.
<h:selectBooleanCheckbox binding="#{myBean.myChk}" onchange="submit();" />
<h:commandButton disabled="#{myBean.myChk.value}" action="myAction" value="myValue" />

Relative positioning of JSF component

Hi,
How can I place a JSF component relative to another component, say I want to place a table below another table whose number of rows may vary.
Thanks,
Bob

Have two differnt tables or use frames and place the controls(tableand button in this case) in different frames.
<table width="100%" height="350"> -outertable
<table .................................................><tr> any number of rows. </tr>-inner table
</table>- - close outer
</tr </table> - close inner
<table> -new table
command button
</table> - close new table

Tutorial on how to create an Ajax-enabled JSF component in Creator?

Is there a tutorial on how to create (not use/import existing) an Ajax-enabled JSF component using Creator 2? I read somewhere that it was done during a presentation in 3 minutes! Now that I really want to see ;-
thanks,
-nikita

As far as I remeber, Edwin Goei's examples are the
closest thing to the info you are looking. He has an
example component, but don't remember if they're
AJAX enabled. Check it on
http://wiki.java.net/bin/view/Javatools/CustomCompone
tLibraries.
Best regards
Antonio.Thanks for the plug. I've been meaning to update that article. Writing an AJAX component is similar to writing other kinds of components but the developer uses AJAX techniques. The latest version of the popup calendar which is checked into the bpcatalog project of java.net uses Dojo which also has some support for AJAX. I haven't yet had time to update the article yet, unfortunately.

Simple JSF component

Im using a simple JSF component <h:selectOneMenu> decribed below:
<h:selectOneMenu value = "Tuesday">

     <f:selectItem itemValue="Wednesday" />
     <f:selectItem itemValue="Thursday" />
</h:selectOneMenu>I use this component in a simple .jsp with nothing else in it. Im tring test the waters. My development environment is WSAD 5.1. When I try to run the .jsp on my test server, I get the following error: (Any idea as to why?)

Favorite JSF component library?

Hi all,
For those of you using one of the many JSF component library, what's your favorite, aesthetically? I've looked at a number of them, especially those listed over at jsfcentral.com. I think RichFaces and ICEFaces aren't bad, although I can't really seem to find one that matches my vision. Most of the ones I've seen feel very "boxy" and just aren't all that impressive. QuipuKit is also pretty good.
So I just want to know if there is any general consensus out there. Obviously everyone is going to have different tastes, but like all the ajax frameworks, I'm trying to whittle down the list to the most popular.
Thanks,
Justin

GetStyle() of JSF component before render

Hey guys,
I'm hoping this is an easy one, here goes...
For one reason or another, I need to modify the CSS of certain components in a JSF page before it is rendered to the browser. The JSF pages are going to be laid out in Netbeans 6.0 (beta right now) using mostly Woodstock components and will have the 'style' attribute filled in for each component. However, like I said, I want to modify the CSS style value of some components prior to rendering.
Looking through the Javadocs for Woodstock (javadocs are included with plugin) I see that many components do indeed give you access to this attribute ('style'), com.sun.webui.jsf.component.Field.getStyle() returns "CSS style(s) to be applied to the outermost HTML element when this component is rendered" for example.
I figured this would be straight forward enough and attempted to retrieve the style using the prerender() method. Unfortunately, getStyle() returned null. After playing around with it for a while, it appears as though the components do not get these properties set (by the Netbeans attribute) until DURING the renderResponse phase. I say this because I tried setStyle() during prerender() and my changes were ignored. I then went back to Netbeans and removed my 'suggested style', now my setStyle() call during prerender() holds showing that somewhere in the renderResponse phase (after prerender()) the style is being set if one is given.
Obviously making any changes after prerender() [like in afterRenderResponse()] will not cut it.
To sum up:
Even as late in the lifecycle as prerender(), the CSS style attribute of a Woodstock component is not yet set (getStyle() returns null and setStyle() ends up being overwritten). Any suggestions on how to modify the style?
Thanks in advance (and I hope this is an applicable forum),
Sean

Solved:
Once I wrapped my head around the problem I found a much more elegant solution.
What I wanted to do was relatively position page fragments but was having trouble as the Netbeans IDE positions components within fragments absolutely. To make my page dynamic I was taking the style="position: absolute" attribute out of the <div> tag that was holding the <jsp:directive-include>. The components within the fragments were then being positioned absolutely on the resulting page, ending up strewn all over the place. This led me off on the tangent to reposition the components when the page was called (original post above).
The weekend did me well I suppose. I came up with the bright idea to CHANGE the style attribute on the <div> tag rather than remove it. Making the <div> component "position: relative" passed its positioning down the the containing components and now my fragments are displayed correctly while being dynamically repositionable.
Hope this helps anyone coming across the same problem.
