[jboss-jira] [JBoss JIRA] (JBMETA-363) Validation errors with "jboss-web_7_0.xsd

[Wolfgang Knauf (JIRA)]

    [ https://issues.jboss.org/browse/JBMETA-363?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12991387#comment-12991387 ] 

Wolfgang Knauf commented on JBMETA-363:
---------------------------------------

Same applies to jboss_web_7_1.xsd and jboss_web_8_0.xsd

Using Eclipse 4.4 (WebTools 3.6), the validation error has changed, but I assume it is still the same source:
"schema_reference.4: Failed to read the schema document 'web-app_3_1.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not 'xsd:schema'

Same happens for jboss-app.xml instances based on "jboss-app_7_0.xsd"

The issue now happens always (without me changing the schema location to a local file), because the JBoss Tools plugin brings all jboss schema files and thus Eclipse can validate them even if they are not published to the web location.

> I tried to create a "jboss-web.xml" file based on the "jboss-web_7_1.xsd"
> As this is not uploaded to the web up to now, I created it with a schema location pointing to my local JBoss 7.2.0Alpha1 snapshot:
> <?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 file:///C:/Temp/jboss-as-7.2.0.Alpha1-SNAPSHOT/docs/schema/jboss-web_7_0.xsd"
>            version="7.0">
> ...
> </jboss-web>
> Eclipse shows validation errors in the XSD file.
> The first on is:
> sch-props-correct.2: A schema cannot contain two global components with the same name; this schema contains two 
> occurences of 'http://java.sun.com/xml/ns/javaee,descriptionGroup'
> (occurs in javaee_6.xsd, line 88)
> And a lot more of those.
> The file was created as part of https://issues.jboss.org/browse/AS7-1262 - and the one who created it found the same validation error.
> It seems the fix is quite simple:
> "jboss-web_7_0.xsd" contains this import:
> <xsd:import namespace="http://java.sun.com/xml/ns/javaee" schemaLocation="web-app_3_0.xsd"/>
> Change it to:
> <xsd:import namespace="http://java.sun.com/xml/ns/javaee" schemaLocation="http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"/>
> The reason seems to be: "jboss-web_7_0.xsd" imports "jboss-common_6-0.xsd", and this one imports "javaee_6.xsd" with a full schema location. 
> The "web-app_3_0.xsd" in "jboss-web_7_0.xsd" has a local schema location, thus the "javaee_6.xsd" import in "web-app_3_0.xsd" points also to local. 
> And this seems to cause a duplicate import of the file.
> (might also be an Eclipse valiation bug)
