मैं एक हाइबरनेट (v 4.1.5.SP1, सत्यापनकर्ता 4.3.0. अंतिम) अनुप्रयोग (एक जार फ़ाइल) एक MySQL 5.5 डीबी पर जेबॉस 4.2.3.GA (इसे बदल नहीं सकता) पर चल रहा है। मुझे त्रुटि मिल रही है "org.hibernate.cache.NoCachingEnabledException: ऐप चलाने पर द्वितीय-स्तर कैश उपयोग के लिए सक्षम नहीं है", लेकिन ऐसा लगता है कि मैंने सही ढंग से सब कुछ ठीक से कॉन्फ़िगर किया है। मैं इन Maven निर्भरता उपयोग कर रहा हूँ ...हाइबरनेट कैश को कॉन्फ़िगर करने में समस्या - org.hibernate.cache.NoCachingEnabledException: उपयोग के लिए द्वितीय-स्तरीय कैश सक्षम नहीं है

त्रुटि अजीब है क्योंकि मैं कैश मेरी hibernate.cfg.xml फ़ाइल में विन्यस्त है ...

इस में शामिल है मेरी META-INF/persistence.xml फ़ाइल है, जो नीचे है ...

</properties>

</persistence>
JBoss classloaders ओवरराइड करने के लिए, मैं META-INF/jboss.xml में इस फाइल में शामिल हैं ...
<jboss>
<class-loading java2ClassLoadingCompliance="false">
<!-- setup classLoader repository. java2ParentDelegation to always have
package libs override server libs for this application -->

यहां पूरा स्टैक ट्रेस है। इसका क्या कारण है?

'hibernate.cache.provider_class है कहते हैं 'org.hibernate.cache.EhCacheProvider' के रूप में परिभाषित किया गया है? – SiB
