schema_reference.4: Failed to read schema document 'http://ehcache.org/ehcache.xsd'

[Ralph]

Hi all,

I hope you can help me with my problem. I just can't see what I'm
doing wrong. I would like to use caching in my Spring web application.

I adjusted my applicationContext.xml and added:

<ehcache:annotation-driven />
<bean id="cacheManager"
class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"/>

I also created ehcache.xml:

<?xml version="1.0" encoding="UTF-8"?>
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd"
updateCheck="false">
<!--
| Please see http://ehcache.sourceforge.net/documentation/configuration.html
for
| detailed information on how to configurigure caches in this
file
+-->
<!-- Location of persistent caches on disk -->
<diskStore path="java.io.tmpdir/
EhCacheSpringAnnotationsExampleApp" />

<defaultCache eternal="false" maxElementsInMemory="1000"
overflowToDisk="false" diskPersistent="false"
timeToIdleSeconds="0"
timeToLiveSeconds="600" memoryStoreEvictionPolicy="LRU"/>

<cache name="weatherCache" eternal="false"
maxElementsInMemory="100" overflowToDisk="false"
diskPersistent="false"
timeToIdleSeconds="0" timeToLiveSeconds="300"
memoryStoreEvictionPolicy="LRU" />

<cache name="locationSearchCache" eternal="false"
maxElementsInMemory="100" overflowToDisk="false"
diskPersistent="false"
timeToIdleSeconds="0" timeToLiveSeconds="300"
memoryStoreEvictionPolicy="LRU" />
</ehcache>


When I run my project, it stops for a moment when it tries to read
ehcache.xml and then gives the error:

org.xml.sax.SAXParseException: schema_reference.4: Failed to read
schema document 'http://ehcache.org/ehcache.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>.

and also:

org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException:
Line 3 in XML document from ServletContext resource [/WEB-INF/
ehcache.xml] is invalid; nested exception is
org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration
of element 'ehcache'.

Does anybody get the same problem or can you help me solving this
problem?

Thank you!
Ralph

Can you access http://ehcache.org/ehcache.xsd from your computer?

If not the schema declaration isn't required in the ehcache.xml config. Try just changing:

<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd" updateCheck="false">

to
<ehcache updateCheck="false">

Hi,

thank you for your quick reply. I still get an error:

org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration
of element 'ehcache'.

Actually I'm not sure that I have the correct setup. I'm not sure how
to link my ehcache.xml in my project.

It's in my web.xml and looks like:

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

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://
java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://
java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
id="WebApp_ID" version="2.5">
<display-name>FLLims</display-name>

<url-pattern>*.xls</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>

If I remove /WEB-INF/ehcache.xml from my web.xml file, I get an error
saying Unable to find projectCache (which I defined in my dao as
@Cacheable(cacheName = "projectCache")
I guess because the application doesn't know of the ehcache.xml file.

Shouldn't I have something like this in my applicationContext:
<ehcache:annotation-driven cache-manager="cacheManager"/>

<bean id="cacheManager"
class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">

<property name="configLocation" value="classpath:/WEB-INF/
ehcache.xml"/>
</bean>

I'm really confused :-) Well, it's the end of the day here, so maybe
that's why.

Thank you!
Ralph

ehcache.xml is not a spring configuration file. It is the Ehcache configuration file and needs to reside in WEB-INF/classes or you need to specify its location.

Your example spring config snippet is close:

<ehcache:annotation-driven cache-manager="cacheManager"/>
<bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
      <property name="configLocation" value="classpath:/WEB-INF/ehcache.xml"/>
</bean>

The problem is /WEB-INF/ehcache.xml is not part of a web applications classpath. Only files under WEB-INF/classes are in the classpath as well as the jars in WEB-INF/lib. Simply moving ehcache.xml to WEB-INF/classes/ehcache.xml and using the following spring configuration should work

<ehcache:annotation-driven cache-manager="cacheManager"/>

<bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean" />

Of course! That did the trick! Thanks a lot!

Cheers
Ralph
