我已經加入到構建以下jar文件：

javax.persistence.jar 
hibernate-entitymanager.jar

有人知道如何解決它？

檢查jar文件是否在classpath中？ – Shriram

你錯過了jboss-common.jar將它添加到你的類路徑。

如果你使用Maven：

金正日你有「java.lang.NoClassDefFoundError XXXXXX」的錯誤，你在谷歌搜索：「行家XXXXXX」。你會發現http://mvnrepository.com/artifact/...

將依賴關係複製/粘貼到pom.xml文件中。

<dependency> 
    <groupId>org.jboss.logging</groupId> 
    <artifactId>jboss-logging</artifactId> 
    <version>3.3.0.Final</version> 
</dependency>

從Maven Repository下載該Jar文件的較新版本，並將其放在lib目錄中。更好地使用Maven。
