jsf - TagException ... null (File not found) on creating custom Facelets tag -

-

this question has answer here:

i creating application based on jsf 2.2 (mojarra). using java ee ear project , dynamic web project generated eclipse, , glassfish server.

i created facelet tag file shown in https://stackoverflow.com/a/5716633/2266635 . when load page containing tag error (and http 500 error):

2014-03-24t00:32:10.904+0100|warning: standardwrappervalve[faces servlet]: servlet.service() servlet faces servlet threw exception javax.faces.view.facelets.tagexception: /index.xhtml @19,19 <fmk:login-form> null     @ com.sun.faces.facelets.tag.usertaghandler.apply(usertaghandler.java:144)     @ javax.faces.view.facelets.compositefacelethandler.apply(compositefacelethandler.java:95)     @ javax.faces.view.facelets.delegatingmetataghandler.applynexthandler(delegatingmetataghandler.java:137)     @ com.sun.faces.facelets.tag.jsf.componenttaghandlerdelegateimpl.apply(componenttaghandlerdelegateimpl.java:190)     @ javax.faces.view.facelets.delegatingmetataghandler.apply(delegatingmetataghandler.java:120)     @ javax.faces.view.facelets.compositefacelethandler.apply(compositefacelethandler.java:95)     @ com.sun.faces.facelets.compiler.namespacehandler.apply(namespacehandler.java:93)     @ com.sun.faces.facelets.compiler.encodinghandler.apply(encodinghandler.java:87)     @ com.sun.faces.facelets.impl.defaultfacelet.apply(defaultfacelet.java:161)     @ com.sun.faces.application.view.faceletviewhandlingstrategy.buildview(faceletviewhandlingstrategy.java:972)     @ com.sun.faces.lifecycle.renderresponsephase.execute(renderresponsephase.java:99)     @ com.sun.faces.lifecycle.phase.dophase(phase.java:101)     @ com.sun.faces.lifecycle.lifecycleimpl.render(lifecycleimpl.java:219)

i have tried copy example @ http://www.mkyong.com/jsf2/custom-tags-in-jsf-2-0/ verbatim, , i'm still getting error (with different tag).

the error @ line 144 of usertaghandler.java filenotfoundexception. if supply invalid file <source> in taglib definition file, same error! never finds file tag source code.

i don't understand why glassfish can't find login-form.xhtml . have tried different paths , tried strace'ing glassfish, without sensible results... ideas wrong?

the problem in server configuration. couldn't find cause, worked on different glassfish instance, deleted domain , re-created it. sorry couldn't find more specific.
