Question

I am noticing a strange issue with respect to spring XML schemas.

I have a standalone java application which uses spring framework. As long as I run this application within eclipse, I do not face any issues. However, when I package this as a jar file (as described in this link), and execute the jar, I get the following exception:

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/tx]
Offending resource: class path resource [applicationContext.xml]

        at org.springframework.beans.factory.xml.DefaultBeanDefinitionDocumentReader.parseBeanDefinitions(DefaultBeanDefinitionDocumentReader.java:184)

I have the following entry in applicationContext.xml and it works fine inside eclipse:

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
           http://www.springframework.org/schema/tx 
           http://www.springframework.org/schema/tx/spring-tx-3.1.xsd">

Any help is much appreciated.

I even tried changing http://www.springframework.org/schema/tx/spring-tx-3.1.xsd to classpath:/org/springframework/transaction/config/spring-tx-3.1.xsd but it did not help.

It looks like your application contains some jars, like spring-core-3.1.x (because its classes are being used), but it’s missing spring-tx-3.1.x.RELEASE.jar (the one that holds Spring Transaction classes).
