-------------------------------------

             Summary: Validation error with "jboss-web_14_0.xsd"
                 Key: JBMETA-418
                 URL: https://issues.redhat.com/browse/JBMETA-418
             Project: JBoss Metadata
          Issue Type: Bug
          Components: web
    Affects Versions: 12.0.0.Final
            Reporter: Wolfgang Knauf
            Assignee: Jean-Frederic Clere


I build a "jboss-web.xml" file referencing jboss-web_14_0.xsd (bundled with WildFly 18), using Eclipse IDE:

{noformat}
{{<?xml version="1.0" encoding="UTF-8"?>
<jboss-web xmlns="http://www.jboss.com/xml/ns/javaee"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="http://www.jboss.com/xml/ns/javaee http://www.jboss.org/schema/jbossas/jboss-web_14_0.xsd"
           version="14.0">
	<context-root>MyWebProject</context-root>

</jboss-web>}}
{noformat}

Eclipse shows validation errors deep in jboss_web_14_0.xsd.

Unfortunately, I can not copy from nested validation errors.
So I will attach a screenshot and type one of the error lines:
sch-props-correct.2: A schema cannot contain two global components with the same name; this schema contains two occurences of 'http://xmlns.jcp.org/xml/ns/javaee,descriptionGroup'

The reason seems to be that "jboss-web_14_0.xsd" imports two files:
* "web-app_4_0.xsd" which imports "web-common_4_0.xsd" which imports "javaee_7.xsd".
* "jboss-common_8_0.xsd" which imports "javaee_8.xsd"

This is quite confusing, as the JavaEE8 standard has a lot of XSD files which import "javaee_7.xsd": [JavaEE schemas|https://www.oracle.com/webfolder/technetwork/jsc/xml/ns/javaee/index.html#8]

It should work if "jboss-web_14_0.xsd" imports "jboss-common_7_1.xsd" and thus "javaee_7.xsd". I don't see any relevant differences beetween "jboss-common_7_1.xsd" and "jboss-common_8_0.xsd", so this should be possible.
