Failed to read schema document

[snkpetrus]

For some reason I get the the following error when starting my application:

SimpleSaxErrorHandler - Method: warning - Ignored XML validation warning
[INFO] org.xml.sax.SAXParseException: schema_reference.4: Failed to read schema document 'http://www.springframework.org/schema/security/spring-security-2.0.4.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>.

The strange thing is that I didn't change anything on my application and all off a sudden this error occurs. My configuration looks like this:

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:security="http://www.springframework.org/schema/security"
	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-2.0.xsd
              http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-2.0.4.xsd">

I also tried this but that didn't work either:

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:security="http://www.springframework.org/schema/security"
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/security
          http://www.springframework.org/schema/security/spring-security-3.0.3.xsd">

I checked the URL's and they seem to be correct when I access them in the browser the xsd shows normally.

Does anybody know what I might be doing wrong?

Which version of Spring Security are you using? You can't use a 2 schema with 3 or vice-versa. If you're using 3.0, make sure you have the spring-security-config jar on your classpath.

That seemed to solve it. We changed our dependency approach in Maven so this JAR wasn't on the classpath in the application anymore. Thnx for pointing this out
