  1. POAdding JMS Info breaks EhCache
    text
    copied!<p>I want to distribute my EhCache via a JMS Topic. This is documented here <a href="http://ehcache.sourceforge.net/documentation/distributed_caching_with_jms.html" rel="nofollow noreferrer">on EhCache's site</a></p> <p>I'm using:</p> <ul> <li>ehcache-1.6.0-beta3</li> <li>ehcache-jmsreplication-0.3</li> <li>spring-2.5</li> <li>spring-modules-0.9</li> </ul> <p>My Spring config looks like this:</p> <blockquote> <pre><code>&lt;bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"&gt; &lt;/bean&gt; &lt;bean id="cacheProvider" class="org.springmodules.cache.provider.ehcache.EhCacheFacade"&gt; &lt;property name="cacheManager" ref="cacheManager" /&gt; &lt;/bean&gt; &lt;ehcache:proxy id="pocDaoCache" refId="pocDao"&gt; &lt;ehcache:caching methodName="fetch" cacheName="pocCache" /&gt; &lt;/ehcache:proxy&gt; </code></pre> </blockquote> <p>And, pre-JMS config, my ehcache.xml looks like this:</p> <blockquote> <pre><code> &lt;diskStore path="c:/projects/cache/demo" /&gt; &lt;defaultCache maxElementsInMemory="50" eternal="false" timeToIdleSeconds="120" timeToLiveSeconds="120" overflowToDisk="true" /&gt; &lt;cache name="pocCache" maxElementsInMemory="10000" maxElementsOnDisk="1000" eternal="false" overflowToDisk="true" diskSpoolBufferSizeMB="20" timeToIdleSeconds="300" timeToLiveSeconds="600" memoryStoreEvictionPolicy="LFU" / &gt; </code></pre> </blockquote> <p>And this works fine. So I add my Topic information:</p> <blockquote> <pre><code> &lt;cacheManagerPeerProviderFactory class="net.sf.ehcache.distribution.jms.JMSCacheManagerPeerProviderFactory" properties="initialContextFactoryName=JmsInitialContextFactory, userName=myuser,password=mypass, providerURL=tcp://jmsdev1-jndi,tcp://jmsdev2-jndi topicConnectionFactoryBindingName=TCF-00, topicBindingName=MyTopiceName" propertySeparator="," /&gt; </code></pre> </blockquote> <p>And I get a NullPointer when I get an application context. Here is the stack trace:</p> <blockquote> <pre><code> org.springframework.beans.factory.BeanCreationException: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'cacheManager' defined in class path resource [cache-context.xml]: Invocation of init method failed; nested exception is java.lang.NullPointerException at org.springframework.beans.factory.support.AbstractAutowireCapableBean Factory.initializeBean(AbstractAutowireCapableBeanFactory.java:1336) at org.springframework.beans.factory.support.AbstractAutowireCapableBean Factory.doCreateBean(AbstractAutowireCapableBeanFactory.java:471) at org.springframework.beans.factory.support.AbstractAutowireCapableBean Factory$1.run(AbstractAutowireCapableBeanFactory.java:409) at java.security.AccessController.doPrivileged(Native Method) at org.springframework.beans.factory.support.AbstractAutowireCapableBean Factory.createBean(AbstractAutowireCapableBeanFactory.java:380) at org.springframework.beans.factory.support.AbstractBeanFactory$1.getOb ject(AbstractBeanFactory.java:264) at org.springframework.beans.factory.support.DefaultSingletonBeanRegistr y.getSingleton(DefaultSingletonBeanRegistry.java:217) [snip] </code></pre> </blockquote> <p>Any ideas from anyone?</p>
