TagException ... null (File not found) on creating custom Facelets tag [duplicate]

Question

I am creating an application based on JSF 2.2 (Mojarra). I am using a Java EE EAR project and a Dynamic Web project generated by Eclipse, and the Glassfish server.

I created a Facelet tag file as shown in https://stackoverflow.com/a/5716633/2266635 . When I load a page containing the tag I get this error (and a HTTP 500 error):

I have also tried to copy the example at http://www.mkyong.com/jsf2/custom-tags-in-jsf-2-0/ verbatim, and I'm still getting the error (with a different tag).

The error at line 144 of UserTagHandler.java is a FileNotFoundException. If I supply an invalid file as <source> in the taglib definition file, I get the same error! So it never finds the file with the tag source code.

I don't understand why Glassfish can't find my login-form.xhtml . I have tried different paths and even tried strace'ing glassfish, but without any sensible results... Any ideas what could be wrong?

Was it helpful?

Solution

The problem was in the server configuration. I couldn't find the cause, but it worked on a different Glassfish instance, so I just deleted the domain and re-created it. Sorry I couldn't find anything more specific.

OTHER TIPS

I was experiencing the same problem, my project (Glassfish 4 + Spring + EJB 3 + JSF 2.2 + Custom Tags) was running fine on my local Glassfish and on a staging server, but on Production it was throwing an exception TagException: /WEB-INF/templates/common.xhtml @38,33 <app:div> null.

After a lot of debugging we found out the problem. If your Glassfish have more than one virtual server configured and your project is deployed and associated with 2 or more, the JSF lib reads the sources files through the current host name you are accessing it, however for custom facelets tags it reads through a different virtual server (probably a bug) and throws a FileNotFoundException (suppressed by TagException).

If you configure your deployed project to only one virtual server, this problem does not occur. That's why when you re-created a fresh domain, it worked, because there was no extra virtual servers.
