no library found for namespace http://omnifaces.org/ui

Apache NetBeans version

Apache NetBeans 16 release candidate

What happened

Since omnifaces 3.0, omnifaces taglib are not recognized by the IDE.

How to reproduce

Create java / jakarta EE (at least 8) web project.
Add omnifaces 3 (if java/jakarta EE 8) or 4 (if jakarta EE >= 9) dependency
Create xhtml page and add xmlns:o="http://omnifaces.org/ui" to the namespaces declaration

Did this work correctly in an earlier version?

No / Don't know

JDK

Java: 11.0.13; Java HotSpot(TM) 64-Bit Server VM 11.0.13+10-LTS-370

Ok find the cause.
In ConfigManager, jakarta ee taglibs are not handled:

netbeans/enterprise/web.jsf.editor/src/org/netbeans/modules/web/jsf/editor/facelets/mojarra/ConfigManager.java

Solution:

• add mojarra-4.0 as an external module (I don't really know how to do this)
• refactor the code in the ConfigManager by calling the new mojarra function DbfFactory.getSchema(ServletContext servletContext, String documentNS, String version, String localName):

https://github.com/eclipse-ee4j/mojarra/blob/b9f62a28133b639a1f1d1f23de02fc7027e8aa23/impl/src/main/java/com/sun/faces/config/manager/DbfFactory.java#L320-L331

Any hint on how to go on?

I am having the same issue for the PrimeFaces library on NetBeans 16.

xmlns:p="http://primefaces.org/ui"

Since I have errors all over the place within my projects due to this, it basically renders 16 final unusable.
Funny how such a major regression made it within 16 final.

Related to this (perhaps) is lack of support for new non-URL URNs for JSF 4.0:

See jakartaee/faces#1553

And I think related to that is the inability to load facelet 4.0 taglib (also "No library found" error):

<facelet-taglib version="4.0"
                xmlns="https://jakarta.ee/xml/ns/jakartaee"
                xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                xsi:schemaLocation="https://jakarta.ee/xml/ns/jakartaee https://jakarta.ee/xml/ns/jakartaee/web-facelettaglibrary_4_0.xsd">
                ...

Same situation in NB 17rc3
What makes Jakarta EE unusable for Jakarta Faces 4.0
Are we to understand that NB no longer supports JSF?

[geertjanw]

You are to understand that NB supports everything you provide support for at github.com/apache/netbeans.

[LouisCollet]

Hi everybody, I am a basic java developer and certainly unable to participate in the development of NB. I would like to continue to evolve and use Jakarta EE... and especially Jakarta Faces 4.0. In no way, my message is a criticism, but a cry for help!

Appreciated, thanks, @LouisCollet.

Tried out NetBeans version 17-RC3. Unfortunately this issue is still present.
On a Java EE 8 project NetBeans does not recognize xmlns:p="http://primefaces.org/ui", i.e., red all over the place. Same remark for a Quarkus project using JSF.

On a Jakarta EE 10 project NetBeans does not recognize xmlns:h="jakarta.faces.html", but there xmlns:p="http://primefaces.org/ui" is OK.
Could somebody have a look at this before version 17? Such basic functionality should not get broken.

[fcorneli]

Strange, version 17 still has this issue, but a build from master not:

ant -Dcluster.config=enterprise build
ant tryme

Here NB can resolve the following without problem:

• xmlns:h="http://java.sun.com/jsf/html"
• xmlns:p="http://primefaces.org/ui"
• xmlns:ejsf="urn:be:e-contract:ejsf"

But fails on

• xmlns:h="jakarta.faces.html"

Using:
https://github.com/e-Contract/enterprise-jsf
as test project.

mmm... opening the same project afterwards with version 17 instead of master, gives the same results as above. pfff... I don't get it.
