Wildfly: Why I get only "Forbidden" if I call my Web application?

Question

Yesterday our web application ran fine on WildFly 9. Since this morning I get only a "Forbidden" in the web browser. We don't use JAAS. There is also no difference if I set the following value to false in the standalone.xml:

...
<subsystem xmlns="urn:jboss:domain:ejb3:3.0">
   ...
   <default-missing-method-permissions-deny-access value="true"/>
   ...
</subsystem>
...

What can be the reasons that WildFly only shows the "Forbidden" page?

EDIT

If I set the log level for package org.jboss.security to TRACE I get the following message in the log file while calling the page:

2016-01-27 12:58:15,354 TRACE [org.jboss.security] (default task-5) PBOX00354: Setting security roles ThreadLocal: null

Not sure what this means ...

What URI are you hitting and where is your app deployed to? – Osteo

@John: The application is deployed from eclipse (by using the JBoss Devel.-Plugin) on a local running WildFly. The URI ist 127.0.0.1:8080/myApp – Gastroenterostomy

Answer 1

My EAR project and the inherited WAR project in eclipse was broken. There were several things missing like at example the application.xml.

Not sure why these things are missing and where I have lost it. But after fixing both projects deployments it works again.

Answer 2

That can occur if you do not have any index.html file at the root of the war file (in WebContent in Eclipse) or your write it wrongly like: Index.html

Same issue if <welcome-file> is not properly set up in WEB-INF/web.xml descriptor

That build must be corrupted. Re-build the application, create war again and deploy it again. It will work.
