Spring + Maven: The matching wildcard is strict, but no declaration can be found for element 'jdbc:embedded-database'

Question

i am currently trying to build a little webapp that uses Spring, Hibernate and Maven (running on a tomcat). It works quite fine, except that i cannot get my embedded-database to work. I hope you can help me.

I am always facing this error, when i am deploying the webapp to the Tomcat:

The matching wildcard is strict, but no declaration can be found for element 'jdbc:embedded-database'

During my investigations i learned that this message is pointing towards missing libraries. Therefore i added my pom.xml, where i added the artifact spring-jdbc.

Can you help me finding the error? Thanks a lot!

This is my spring-configuration-file, which causes the error during initialization of the webapp:

<?xml version="1.0" encoding="UTF-8"?>

Answer 1

This line in your Spring context file:

xmlns:jdbc="http://www.springframework.org/schema/jdbc/spring-jdbc-3.1.xsd"

should be changed to :

xmlns:jdbc="http://www.springframework.org/schema/jdbc"

Not sure what IDE you're using but with some (IntelliJ for example) this would be flagged as an error and save a lot of headache!

Answer 2

For me it was to add xmlns:jdbc and xsi:schemaLocation

<beans ....

    xmlns:jdbc="http://www.springframework.org/schema/jdbc"

    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
    .....
    http://www.springframework.org/schema/jdbc
    http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd"
    default-lazy-init="true">

also add
