“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 []
Offending resource: class path resource [applicationContext.xml]

at org.springframework.beans.factory.parsing.FailFastProblemReporter.error(
at org.springframework.beans.factory.parsing.ReaderContext.error(
at org.springframework.beans.factory.parsing.ReaderContext.error(
...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

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

    <bean id="dataSourceDesenv" class="org.apache.commons.dbcp.BasicDataSource"... />

    <bean id="simpleJdbcDaoSupport" class="org.springframework.jdbc.core.simple.SimpleJdbcDaoSupport"
      p:dataSource-ref="dataSourceDesenv" />

    <bean id="simpleJdbcTemplate" class="org.springframework.jdbc.core.simple.SimpleJdbcTemplate">
        <constructor-arg ref="dataSourceDesenv" />



I found the error, the bug lies in an unfixed bug in the maven-assembly plugin. I used the following workaround:

First commented out the maven-assembly code in my pom. Then I copied the dependencies to a lib folder at the target using the maben-dependency-plugin:


Then I used the maven-jar-plugin to setup my executable jar:



Finally I created a bash script that is deployed with the application that runs my app with its libs and any provided arguments:

java -cp lib/*:myproject-0.0.1-SNAPSHOT.jar [email protected]

I should have built the app in python =/
