GWT RPC应用程序中的异常

在编译我的项目时(2,我遇到了这个例外.以前有人见过这个吗？

我在GWT项目的编译期间遇到此错误,没有像'gwt-UnitCache'这样的文件夹要删除,如下面的问题所示

• 奇怪的GWT编译错误

• GWT RPC应用程序中的异常

我正在使用IntelliJ IDEA(IDE),SmartGWT EE(框架),JBoss AS(服务器)和JPA

这是错误日志:

我正在尝试创建一个简单的GWT RPC Hibernate程序,将用户添加到MySQL数据库.我正在使用Eclipse EE.应用程序成功将用户添加到数据库,但在编译时会引发异常.这是我的应用程序的例外和来源.

例外:

当我在 Eclipse 中运行 GWT 应用程序时，出现了 unitcache 异常。

我不明白为什么它会来...我还从 war 文件夹中删除了缓存文件和部署文件夹并编译了应用程序，但它不起作用...

我还重新启动了 Eclipse IDE 并尝试，但结果是相同的，它停止到“loadCompleteLatch.countDown();” PersistentUnitCache.java 文件中的行...

以下是我得到的异常：
