Failed to read schema document of spring.security
java, spring, spring-security, xml, xsd
Solution
Your xml file should start with something like this:
<beans:beans xmlns="http://www.springframework.org/schema/security"
xmlns:beans="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-3.0.xsd
http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.2.xsd">
and the .xsd schemas are in `spring-security-config` jar.
Problem
My spring-security.xml is ``` <beans:beans xmlns="http://www.springframework.org/schema/security" xmlns:beans="http://www.springframework.org/schema/beans" 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-3.2.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <http auto-config="true"> <intercept-url pattern="/admin**" access="ROLE_USER" /> </http> <authentication-manager> <authentication-provider> <user-service> <user name="admin" password="admin" authorities="ROLE_USER" /> </user-service> </authentication-provider> </authentication-manager> ``` When I start the server (Tomcat 7) inside Eclipse I get this error: Ignored XML validation warning org.xml.sax.SAXParseException: schema_reference.4: Failed to read schema document 'http://www.springframework.org/schema/security/spring-security-3.2.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not . The libraries I've imported are: commons-logging - jsp - jstl - spring-aop-4.0.4 - spring-beans-4.0.4 - spring-context-4.0.4 - spring-core-4.0.4 - spring-expression-4.0.4 - sprig-web-4.0.4 - spring-webmvc-4.0.4 - spring-security-core-3.2.4 I believe there are some problems with the library version, but I'm not sure. I tried to search the version 4.0.4 but I haven't found it. Is the spring-security library included in another one? If yes, where can I look into when I need to know the unifications between the spring versions? How can I solve the error? I googled all my questions but I haven't found anything.
