Hibernate C3P0 - NoClassDefFoundError

Question

当我第一次在Glassfish上查询我的Struts应用程序时，会发生这样的错误：

Severe: Initial SessionFactory creation failed.java.lang.NoClassDefFoundError: com/mchange/v2/c3p0/DataSources
Info: 2015-07-28 13:59:17 ERROR HibernateUtil:54 - Initial SessionFactory creation failed

    at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1840)
    [...]

我尝试使用this article解决此问题，但仍然发生同样的错误..

我用来运行此应用程序的依赖项：

        <dependency>
                <groupId>org.hibernate</groupId>
                <artifactId>hibernate-core</artifactId>
                <version>3.6.3.Final</version>
                <type>jar</type>
        </dependency>
        <!-- Hibernate c3p0 connection pool -->
        <dependency>
                <groupId>org.hibernate</groupId>
                <artifactId>hibernate-c3p0</artifactId>
                <version>3.6.3.Final</version>
        </dependency>
        <dependency>
                <groupId>org.hibernate</groupId>
                <artifactId>hibernate-tools</artifactId>
                <version>3.6.0.CR1</version>
        </dependency>
        <dependency>
                <groupId>com.mchange</groupId>
                <artifactId>mchange-commons-java</artifactId>
                <version>0.2.10</version>
        </dependency>
        <dependency>
                <groupId>c3p0</groupId>
                <artifactId>c3p0-oracle-thin-extras</artifactId>
                <version>0.9.0.2</version>
        </dependency>
        <dependency>
                <groupId>com.mchange AND c3p0</groupId>
                <artifactId>c3p0</artifactId>
                <version>0.9.2.1</version>
        </dependency>

这个应用程序完美无需Maven ..

感谢您的帮助！ ：）

Answer 1

在

<dependency>
   <groupId>com.mchange AND c3p0</groupId>
   <artifactId>c3p0</artifactId>
   <version>0.9.2.1</version>
</dependency>

AND c3p0是多余的。

应该是

<dependency>
   <groupId>com.mchange</groupId>
   <artifactId>c3p0</artifactId>
   <version>0.9.2.1</version>
</dependency>

或者更好的是，使用当前的生产版本

<dependency>
   <groupId>com.mchange</groupId>
   <artifactId>c3p0</artifactId>
   <version>0.9.5.1</version>
</dependency>

Answer 2

问题已解决 - 我必须将c3p0- [version] .jar添加到 domains / domain1 / libs

下的 Glassfish libs目录中
