Create Dynamic Web Project with Java Server Faces on WIldFly server? [message #1757913]

I can create, deploy and run a simple project with a .jsp where I combine java and html.

However, I cannot wrap my head around using simple tags like <f:view>.
Whatever I do, the taglibs
<%@ taglib ...>
are flagged with "Can not find the tag library descriptor..." errors, and subsequent use of tags yield an "Unknown tag <f:view>" error.

I have found lots of old issues with tag libraries, which could be resolved by adding the right library to the project, but nothing more recent (running eclipse neon), so I guess I am overlooking something real basic. Any help is appreciated...

The first question is whether your page runs anyway, with the project correctly targeting and compiling against WildFly (instead of something different like the built-in "J2EE Preview"). Then, if so, it comes to why the JSF library is not being found within Eclipse. So, does the page run?

As I mentioned, I can run my project. It runs on server, outside eclipse.
That is, the project runs without tags added, just java and html.

The interesting part, for this question, is what happens with the tags added.

It gives the errors mentioned above, the project cannot be built.

Are you unable to launch it regardless? Is there any configuration you're supposed to do to enable JSF on WildFly?

I cannot compile, build or deploy the .jsp file; the server is running. I don't think Wildfly needs to be tweaked to enable JSF.

I can easily reproduce the problem:
1. Create Dynamic Web Project, targetting WIldfly 10.x runtime, enable JavaServer Faces facet
2. Add .jsp file (the default template gives you a <f:view> tag
3. Open the newly created .jsp file: the taglibs are marked as error.

I would appreciate if someone out there could try this one for me to check whether it works...

I just found out that using Glassfish instead of Wildfly gives me exactly the same errors.
I guess the problem does not depend on the application server used.

Could someone out there running Ubuntu check whether the above works, and let me know about versions of eclipse and server?

Finally got this sorted out: I did a complete reinstall of eclipse and tools, and this finally started to make sense.
Looks like eclipse got screwed up in silence.
