Configuration error: Unable to find Spring namespace namespace for XML schema space [http://www.springframework.org/schema/tx]

Question

When starting the JBOSS server, I get this error,

19:44:59,307 ERROR [STDERR] 23813 [main] ERROR org.springframework.web.context.ContextLoader - Context initialization failed 19:44:59,307 ERROR [STDERR] 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: ServletContext resource [/WEB-INF/applicationContext.xml] 19:44:59,307 ERROR [STDERR] at org.springframework.beans.factory.parsing.FailFastProblemReporter.error(FailFastProblemReporter.java:68) 19:44:59,307 ERROR [STDERR] at org.springframework.beans.factory.parsing.ReaderContext.error(ReaderContext.java:85) 19:44:59,307 ERROR [STDERR] at org.springframework.beans.factory.parsing.ReaderContext.error(ReaderContext.java:80) 19:44:59,307 ERROR [STDERR] at org.springframework.beans.factory.xml.BeanDefinitionParserDelegate.error(BeanDefinitionParserDelegate.java:281) 19:44:59,307 ERROR [STDERR] at org.springframework.beans.factory.xml.BeanDefinitionParserDelegate.parseCustomElement(BeanDefinitionParserDelegate.java:1294) 19:44:59,307 ERROR [STDERR] at org.springframework.beans.factory.xml.BeanDefinitionParserDelegate.parseCustomElement(BeanDefinitionParserDelegate.java:1287) 19:44:59,307 ERROR [STDERR] at org.springframework.beans.factory.xml.DefaultBeanDefinitionDocumentReader.parseBeanDefinitions(DefaultBeanDefinitionDocumentReader.java:135) 

and this is what my application.xml looks like,

 <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" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd"> 

I am using spring 2.5.6 ... Any suggestion about the error.

Answer 1

This may be due to the fact that you are missing the spring-tx*.jar file in your class path. You can check if this file is in the classpath.

Answer 2

For future references:

If you are using Maven, you may have forgotten the spring -tx dependency.

  <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${org.springframework.version}</version> </dependency>
