Validation errors with "jboss-web_7_0.xsd ----------------------------------------- Key: JBMETA-363 URL: https://issues.jboss.org/browse/JBMETA-363 Project: JBoss Metadata Issue Type: Bug Security Level: Public(Everyone can see) Components: web Affects Versions: 7.0.5.Final, 8.1.0.Beta1 Environment: Eclipse Reporter: Wolfgang Knauf Assignee: Jean-Frederic Clere 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&qu... 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)
