non è riuscito a leggere il documento schema 'http://www.springframework.org/schema/beans/spring-beans-3.0.xsd'

Question

Mentre iniziare la mia Primavera App, sto ottenendo il seguente errore:

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>. 

mio SpringApp-servlet.xml è la seguente:

<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> 

si prega di suggerire.

Answer 2

Quando ho ricevuto questo messaggio di errore, era semplicemente a causa di un vaso mancante nel mio CLASSPATH. Alcune applicazioni primaverili sembrano essere molto affamate di vasi di primavera. La mia app ha bisogno di tutte queste cose sul classpath:
