Failed to read schema document spring xsd
I know it's a common problem but I tried a lot of solutions already proposed here and none of them works :/
I had an existing project which runs on an old Jboss 4.2.3. So I'm migrating it to Wildfly 8. I have the 4.0.6 spring version configured in my pom.xml everywhere in project.
In my databaseBeans.xml I had 2.5 version of xsd configured before migration, so I put the new version :
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.0.xsd">
<bean id="mappingList" class="java.util.ArrayList">
But I'm getting :

What I'm doing wrong ?
EDIT :
I try to debug the code, and when the XML is read, I see a difference between Jboss version and Wildly version.
Jboss version with a "UnifiedClassLoader" has dozen of "packages" loaded in it (included spring-beans and others things) :
Wildfly version with a "ModuleClassLoader" has only 2 packages, and not the spring-beans jar :
It seems to be a problem with my two files for my App : 1 war and 1 .ear file.
The .ear file is not loaded like Jboss, and miss the spring dependencies.
But why in the stack trace we see "spring-beans-4.0.6.RELEASE.jar" mentioned in this case ?
Solution
I successfully solved the problem following this tutorial :
https://access.redhat.com/solutions/168093
Briefly, I create a modules/org/springframework/spring/main/module.xml file, with the spring jar in resources. I copy the spring jar already present in tmp/deployment/vfs on the server in this directory : modules/org/springframework/spring/main/ And then I create a jboss-deployment-structure in my app and add the spring modules.
But, I don't really understand why I need to do all of this, creating a spring module...etc for Wildfly
The spring are dependencies of the project, and jar are available, so why it doesn't work simply like this ?
