ehcache.CacheManager - Configuring ehcache from classpath

hollisin · **Posted:** Mon Nov 08, 2010 11:55 am

I have tried many different setting and none work. When I name the xml file ehcache.xml it works fine no matter what I specify as a resource name. I have looked at the ehcache configuration code online and it seems to always pick this option (below)and does not find the file.

Any help would be appreciated.

Code:

117     /***
118      * Configures a bean from an XML file in the classpath.
119      */
120     public static Configuration parseConfiguration() throws CacheException {
121         ClassLoader standardClassloader = ClassLoaderUtil.getStandardClassLoader();
122         URL url = null;
123         if (standardClassloader != null) {
124             url = standardClassloader.getResource(DEFAULT_CLASSPATH_CONFIGURATION_FILE);
125         }
126         if (url == null) {
127             url = ConfigurationFactory.class.getResource(DEFAULT_CLASSPATH_CONFIGURATION_FILE);
128         }
129         if (url != null) {
130             LOG.debug("Configuring ehcache from ehcache.xml found in the classpath: " + url);
131         } else {
132             url = ConfigurationFactory.class.getResource(FAILSAFE_CLASSPATH_CONFIGURATION_FILE);
133 
134             LOG.warn("No configuration found. Configuring ehcache from ehcache-failsafe.xml "
135                     + " found in the classpath: {}", url);
136 
137         }
138         Configuration configuration = parseConfiguration(url);
139         configuration.setSource(ConfigurationSource.getConfigurationSource());
140         return configuration;
141     }

codes.hibernate.cfg

Code:

<property name="hibernate.cache.provider_class">net.sf.ehcache.hibernate.SingletonEhCacheProvider</property>           
<property name="net.sf.ehcache.configurationResourceName">/ehcachx.xml</property> 

or to hibernate.properties

Code:

hibernate.cache.region.factory_class=net.sf.ehcache.hibernate.EhCacheRegionFactory
net.sf.ehcache.configurationResourceName="ehcachx.xml"

hibernate.cache.use_second_level_cache=true
hibernate.cache.use_query_cache=true  
hibernate.generate_statistics=true
