I'm facing with this problem when I try to run the application:

In web.xml listeners are configured in this manner:
<listener>
<listener-class>com.iss.congress.core.util.CongressContextListener</listener-class>
</listener>
<listener>
<listener-class>com.iss.congress.core.util.CongressHttpSessionListener</listener-class>
</listener>
<listener>
<display-name>Hibernate Session Listener</display-name>
<listener-class>com.iss.congress.core.util.HibernateListener</listener-class>
</listener>

这是
java.lang.ClassNotFoundException: com.iss.congress.core.util.HibernateListener的情况，表示类别HibernateListener不在类别路径中。请确定包含此类别的jar存在于应用程序的WEB-INF/lib文件夹中。如果src文件夹中存在该类，请检查包名。包名/类名区分大小写。

可能有以下任何原因：
1.您的类文件在指定的位置不可用（请检查您的package_name/class_file_name.java）
1.或者，文件存在于指定位置，但文件中有错误，可以生成（生成类文件）
(for问题的根本原因是，我更改（升级）了rest库的版本，这导致了现有类文件的问题。
我通过添加/选择适当的apache tomcat服务器解决了一个问题。

碰巧我在listener类中编辑了它，在我保存它并将应用程序重新发布到tomcat后，我发现类的错误未找到。
我所做的是删除我在侦听器类中的更新，重新发布到Tomcat，然后再次添加更新..我这样做是因为我怀疑无论什么原因Eclipse in .class生成中存在问题，尽管我清理了项目几次。
删除我的更新，保存（以拥有类的新编译版本），然后再次添加我的更新，已经为我解决了这个问题。
是的，这似乎不合逻辑，但IDE问题有时会发生。

在我的情况下，一些jar文件丢失，如javax.ejb-api-3.2.jar在Tomcat目录的libs文件夹中丢失。也请检查项目的.m2资源库的jar libs。
