no ha podido leer documento de esquema 'http://www.springframework.org/schema/beans/spring-beans-3.0.xsd'

Question

Al iniciar mi aplicación primavera, estoy consiguiendo el error siguiente:

WARNING: Ignored XML validation warning 
org.xml.sax.SAXParseException: schema_reference.4: Failed to read schema document  
'http://www.springframework.org/schema/beans/spring-beans-3.0.xsd', because 
1) could not find the document; 
2) the document could not be read; 
3) the root element of the document is not <xsd:schema>. 

Mi springapp-servlet.xml es el siguiente:

<beans xmlns="http://www.springframework.org/schema/beans" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   
xmlns:aop="http://www.springframework.org/schema/aop"  
xsi:schemaLocation="http://www.springframework.org/schema/beans 
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> 
<bean name="/hello.htm" class="springapp.web.HelloController"/> 
</beans> 

Para sugerir.

Cuando recibí este mensaje de error, era simplemente porque faltaba un jar en mi CLASSPATH. Algunas aplicaciones de primavera parecen estar muy hambrientas de jarras de primavera. Mi aplicación terminó necesitando todos estos en classpath:

${OTS_DIR}/org.springframework.aop-${VERSION}.jar:\ 
${OTS_DIR}/org.springframework.aspects-${VERSION}.jar:\ 
${OTS_DIR}/com.springsource.org.aopalliance-${AOPALLIANCE_VER}.jar:\
