Spring schemaLocation fails when there is no internet connection

Question

I am using Spring and in application-context.xml I have the following definitions:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:util="http://www.springframework.org/schema/util"
   xmlns:context="http://www.springframework.org/schema/context"
   xmlns:aop="http://www.springframework.org/schema/aop"
   xmlns:tx="http://www.springframework.org/schema/tx"
   xmlns:p="http://www.springframework.org/schema/p"
   xmlns:security="http://www.springframework.org/schema/security"
   xsi:schemaLocation="
   http://www.springframework.org/schema/beans 
   http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
   http://www.springframework.org/schema/util 
   http://www.springframework.org/schema/util/spring-util-2.0.xsd
   http://www.springframework.org/schema/context
   http://www.springframework.org/schema/context/spring-context-2.1.xsd
   http://www.springframework.org/schema/tx
   http://www.springframework.org/schema/tx/spring-tx.xsd
   http://www.springframework.org/schema/aop
   http://www.springframework.org/schema/aop/spring-aop-2.0.xsd
   http://www.springframework.org/schema/security
   http://www.springframework.org/schema/security/spring-security-2.0.xsd"
   >

.....

When my internet connection is lost, I cannot run my application via tomcat or jetty.

It gives:

[main] WARN  org.springframework.beans.factory.xml.XmlBeanDefinitionReader - Ignored XML validation warning

Any suggestions how to fix it?

Answer 1

There is no need to use the classpath: protocol in your schemaLocation URL if the namespace is configured correctly and the XSD file is on your classpath.

Spring doc "Registering the handler and the schema" shows how it should be done.

In your case, the problem was probably that the spring-context jar on your classpath was not 2.1. That was why changing the protocol to classpath: and putting the specific 2.1 XSD in your classpath fixed the problem.

From what I've seen, there are 2 schemas defined for the main XSD contained in a spring-* jar. Once to resolve the schema URL with the version and once without it.

As an example see this part of the spring.schemas contents in spring-context-3.0.5.RELEASE.jar:

http\://www.springframework.org/schema/context/spring-context-2.5.xsd=org/springframework/context/config/spring-context-2.5.xsd
http\://www.springframework.org/schema/context/spring-context-3.0.xsd=org/springframework/context/config/spring-context-3.0.xsd
http\://www.springframework.org/schema/context/spring-context.xsd=org/springframework/context/config/spring-context-3.0.xsd

This means that (in xsi:schemaLocation)

http://www.springframework.org/schema/context/spring-context-2.5.xsd 

will be validated against

org/springframework/context/config/spring-context-2.5.xsd 

in the classpath.

http://www.springframework.org/schema/context/spring-context-3.0.xsd 

or

http://www.springframework.org/schema/context/spring-context.xsd

will be validated against

org/springframework/context/config/spring-context-3.0.xsd 

in the classpath.

http://www.springframework.org/schema/context/spring-context-2.1.xsd

is not defined so Spring will look for it using the literal URL defined in schemaLocation.

Answer 2

I solved it

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:util="http://www.springframework.org/schema/util"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:p="http://www.springframework.org/schema/p"
       xmlns:security="http://www.springframework.org/schema/security"
       xsi:schemaLocation="
       http://www.springframework.org/schema/beans 
       http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
       http://www.springframework.org/schema/util 
       http://www.springframework.org/schema/util/spring-util-2.0.xsd
       http://www.springframework.org/schema/context
       classpath:spring-context-2.1.xsd
       http://www.springframework.org/schema/tx
       http://www.springframework.org/schema/tx/spring-tx.xsd
       http://www.springframework.org/schema/aop
       http://www.springframework.org/schema/aop/spring-aop-2.0.xsd
       http://www.springframework.org/schema/security
       http://www.springframework.org/schema/security/spring-security-2.0.xsd"
       >

classpath:spring-context-2.1.xsd is the key for working offline mode (no internet connection). Also i copied spring-context-2.1.xsd near (same directory) the application-context.xml file

Answer 3

Something like this worked for me.

xsi:schemaLocation=
"http://www.springframework.org/schema/beans 
             classpath:org/springframework/beans/factory/xml/spring-beans-3.0.xsd
http://www.springframework.org/schema/context 
             classpath:org/springframework/beans/factory/xml/spring-context-3.0.xsd"

Answer 4

In case anyone arrives here via the same root I did - I hit this problem because I was building a single JAR with all dependencies, including Spring JARs. As a result the spring.schemas file in some of the META-INF directories of Spring JARs was overwritten.

I found suggested solutions here: How to create spring-based executable jar with maven?
