"unable to locate Spring NamespaceHandler" error

I'm creating a stand-alone Sava application with Spring, to handle the JDBC access. The application works fine on every test and I decided that I need a jar to be deployed our clients.

They might not have spring in their classpath, so I used maven-assembly-plugin to handle the jar creation with dependencies.

However when I try to run the application:

java -jar target/myproject-0.0.1-SNAPSHOT-jar-with-dependencies.jar

Which throws the following error:

Exception in thread "main" org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/p]
Offending resource: class path resource [applicationContext.xml]

at org.springframework.beans.factory.parsing.FailFastProblemReporter.error(FailFastProblemReporter.java:68)
at org.springframework.beans.factory.parsing.ReaderContext.error(ReaderContext.java:85)
at org.springframework.beans.factory.parsing.ReaderContext.error(ReaderContext.java:80)
...and so on to the database access class of this project.

The applicationContext.xml file is in projectbase/src/main/resources. And its placed at target/packagename base.

The applicationContext.xml

(Assuming that you've added all the right headers for the XML, if you're still facing this issue which was my case) I know that the question was asked with Maven but I'm using Gradle and I faced the exact same problem. For anyone else who's using Gradle to package Jars and are facing this problem, here's how I solved it,

jar {
    manifest {
        attributes("Created-By"      : ".....",
                "Specification-Title": ".....",
                "Main-Class"         : "$mainClassName",
                "Class-Path"         : configurations.compile.collect { it.getName() }.join(' '))
    }
}

Adding "Class-Path" as a compile collect solved it for me.

If anyone comes across this error after using the above code,

 Cannot change dependencies of configuration ':compile' after it has been resolved.

You need to move this block after your "dependencies" block.
