I am working on a simple web application as a demo. And i am stuck at this error. Tomcat application server reports the following error on accessing the application context url. I couldn't figure what is the cause of this error.

mvn clean package builds the package fine

org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 9 in XML document from ServletContext resource [/WEB-INF/dispatcherServlet-servlet.xml] is invalid; nested exception is org.xml.sax.SAXParseException; systemId: http://www.springframework.org/schema/tx/spring-tx-4.3.xsd; lineNumber: 9; columnNumber: 38; TargetNamespace.1: Expecting namespace 'http://www.springframework.org/schema/data/jpa', but the target namespace of the schema document is 'http://www.springframework.org/schema/tx'.

Here's the dispatcherServlet-servlet.xml:

CodePudding user response：

I would guess the problem is this line:

http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/tx/spring-tx-4.3.xsd">

It should be something like this:

http://www.springframework.org/schema/data/jpa www.springframework.org/schema/data/jpa/spring-jpa-1.11.xsd">

Iam not a Spring expert, but I would guess this is a mapping from the namespace to a file that defines the Namespace
