Failed to read 'http://www.springframework.org/schema/context/spring--context-3.0.xsd

[likesky3]

Hi,

I was trying to use <context:component-scan> in my demo project and encounter an error.
I have searched the solutions on the Internet, but can't get satisfied answer.

The following two links are similar with my problems:
[1]http://forum.springsource.org/showthread.php?77633-schema-document-http-www-springframework-org-schema-beans-spring-context-3-0-xsd

[2]http://stackoverflow.com/questions/1729307/spring-schemalocation-fails-when-there-is-no-internet-connection

The first one's error message is almost same with me, however the reason is he made a copy/paste mistake in configure file. I checked my file and there is no such problem.

The second solution does solve my problem, but not perfectly. I will get correct result of my app when apply this
solution, but it's a solution for offline mode(without Internet connection). Moreover, there is still error information saying "Failed to read schema document 'http://www.springframework.org/schema/tool/spring-tool-3.0.xsd'"

My configure file is:

<?xml version = "1.0" encoding = "UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context"
	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-3.0.xsd
	http://www.springframework.org/schema/context
	http://www.springframework.org/schema/context/spring-context-3.0.xsd">

	<context:component-scan base-package="com.springinaction.autodiscovery" />
	
</beans>

When I replace the "spring-context-3.0.xsd" with "spring-context-2.5.xsd", everything is OK.
Also, I can view the content of both "spring-context-3.0.xsd" and "spring-context-2.5.xsd" from the Eclipse.
I want to know the reason of the problem and the strange phenomena.


Thank you in advance~

Here is the error I got:

Make sure that there aren't any conflicting jars (different spring versions) on the classpath. If you use spring 3.0 there should be no big fat spring.jar (which is spring 2.5 and before). Next if you are creating a uber jar which contains all packages als make sure you copy xsd files also.

I'm sure there is no conflict jars in my project, all referenced jars on my build path are:
antlr-runtime-3.0.jar
commons-logging-1.0.4.jar
org.springframework.asm-3.0.0.M3.jar
org.springframework.beans-3.0.0.M3.jar
org.springframework.context-3.0.0.M3.jar
org.springframework.context.support-3.0.0.M3.jar
org.springframework.core-3.0.0.M3.jar
org.springframework.expression-3.0.0.M3.jar

Also, my project is only a small demo app, it can be downloaded from the attachment.

Well seems like the Spring in Action sample .

Also why are you using an ancient milestone version of spring? I suggest at least upgrading to a final version (3.0.7 or 3.1.1)

[likesky3]

Thank you very much, Marten! I upgrade the spring jars to version 3.1.1 and it worked properly.
My tiny app is indeed sample from the "Spring in Action", , I'm currently reading this book.

Thanks for the solution. I had the same problem with version 3.1.1.RELEASE and had to rollback to 3.1.0.RELEASE. After the change no problem left.
