Problem with writing Custom Components

j.v. Mar 4, 2011 2:30 AM

Hi together,

I'm trying to write a Custom Component for a confirmation-dialog in Richfaces.

I've created a confirm.xhtml wich has a modal panel.

This confirmation.xhtml is refered in the mytag-taglib.xml:

<?xml version="1.0"?>
<!DOCTYPE facelet-taglib PUBLIC
        "-//Sun Microsystems, Inc.//DTD Facelet Taglib 1.0//EN"
        "http://java.sun.com/dtd/facelet-taglib_1_0.dtd">

<facelet-taglib>
    <namespace>http://myconfirmdialog.com/richx</namespace>
    <tag>
        <tag-name>confirm</tag-name>
        <source>/view/confirmation.xhtml</source>
    </tag>
</facelet-taglib>

The taglib is refered in the web.xml:

    <context-param>
        <param-name>facelets.LIBRARIES</param-name>
        <param-value>mytag-taglib.xml</param-value>
    </context-param>

Everything seems to be OK, but if i try to use this confirmation dialog, I get an empty tag <richx:confirm></richx:confirm> as result.

I tried to minimize the confirmation.xhtml, so that there is only an outputText on it, but i get the same result.

Can someone help me with this problem?

best regards

1) I suppose you have already read something like this article:
http://www.ibm.com/developerworks/java/library/j-facelets/
I just wanted to pointed out on this one because it's very clear and detailed.
2) Are you using jsf 1.2?
3) Have you declared library "http://myconfirmdialog.com/richx" with prefix "richx" in your xhtml page? Please provide a full sample of your page.
4) Where did you place "mytag-taglib.xml"?

Hi Ilya,

1) You're right, i've read some articles and tutorials. I tried to do the same as in the tutorials, but the problem stays.
2) Yes, I'm using jsf 1.2
3) I have declared the richx prefix
4) I've placed my mytag-taglib.xml in the WEB-INF directory. I've tried other locations like META-INF without any result.

Well. I have the following and it works fine:
<context-param>
        <param-name>facelets.LIBRARIES</param-name>
        <param-value>
                    /WEB-INF/facelets/tags/my.taglib.xml;
        </param-value>
    </context-param>
In WEB-INF/facelets/tags/my.taglib.xml
<?xml version="1.0"?>
<!DOCTYPE facelet-taglib PUBLIC
"-//Sun Microsystems, Inc.//DTD Facelet Taglib 1.0//EN"
"facelet-taglib_1_0.dtd">

<facelet-taglib>
    <namespace>http://www.my.com/jsf</namespace>
    <tag>
        <tag-name>myTag</tag-name>
        <source>myTag.xhtml</source>
    </tag>
</facelet-taglib>
My myTag.xhtml is placed in
WEB-INF/facelets/tags/
And it looks like:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.og/TR/xhtml1/DTD/xhtml-transitionl.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
            xmlns:f="http://java.sun.com/jsf/core"
            xmlns:h="http://java.sun.com/jsf/html"
            xmlns:ui="http://java.sun.com/jsf/facelets"
            xmlns:a4j="http://richfaces.org/a4j"
            xmlns:rich="http://richfaces.org/rich"
               xmlns:c="http://java.sun.com/jstl/core"
      xmlns:fn="http://java.sun.com/jsp/jstl/functions">

          <ui:composition>
   ... my tag content...
          </ui:composition>

</html>
And then it works fine on my facelets pages.
Which version of facelets are you using?

Hi Ilya,

I use facelets version 1.1.15.

I implemented my custom component exactly like yours, but it doesn't work.

So, does this:

<context-param> <param-name>facelets.LIBRARIES</param-name> <param-value>mytag-taglib.xml</param-value> </context-param>

points to the correct location including WEB-INF etc?

Yes, the it points to the right location.
I've tried different locations, but no one worked.
