glassfish Rest WEB9031异常

我在Glassfish 3.1.2上部署了一个Rest Web服务。我偶尔会得到一个特殊的例外

我的Web服务在处理后在服务器上封送xml。xml包含标记中的时间集

GregorianCalendar gc = (GregorianCalendar) GregorianCalendar
            .getInstance();
globalContextObj.setDateOfCreation(DatatypeFactory.newInstance()
                        .newXMLGregorianCalendar(gc));

JAXBXML对象是类的私有成员变量，将访问修饰符从static更改为none不会影响异常。我读到关于

WEB9031

异常的信息，它是由类加载器无法加载时区类库引起的。Glassfish文档表明，在部署时，我们必须提到控制台中的公共库。但我没有公共图书馆。我认为异常中提到的java.util.timezone类正在卸载或类似的情况

---

如果有人有任何想法来解决这个问题，请让我知道

根据甲骨文的说法，原因和解决方案是：

原因： 此问题通常表示web应用程序的类加载器已缓存，并且正在尝试让它加载资源，即使与该类加载器关联的web应用程序已取消部署

解决方案： 确保与web应用程序关联的类加载器在web应用程序的生命周期之后未被缓存和使用

因为您的问题看起来是零星的，所以听起来可能是缓存问题。但我个人认为，当Glassfish本身是Java应用程序的服务器时，应该没有必要要求Glassfish用户在Glassfish的类路径上放置一个标准Java类（

Java.util.TimeZone

）！建议在从控制台启动域时提及包含

java.util.TimeZone

的类，这可能只起作用，因为它会将库添加回类路径

尝试停止并再次启动域以刷新缓存

---

我面临着一个类似的问题，重新启动域名似乎不适合我。我只是想我会建议你，因为听起来不像你那样。

执行以下步骤

取消部署glassfish服务器中部署的所有应用程序

停止glassfish服务器

清除glassfish缓存。（清除以下文件夹内容）

• $GLASSFISH_HOME/GLASSFISH/domains/domain1/generated/*

• $GLASSFISH_HOME/GLASSFISH/domains/domain1/osgi缓存/*

• $GLASSFISH_HOME/GLASSFISH/domains/domain1/applications/*

现在重新启动glassfish服务器
