我在Glassfish 3.1.2上部署了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编组xml。 xml包含标记

中设置的时间 
GregorianCalendar gc = (GregorianCalendar) GregorianCalendar
            .getInstance();
globalContextObj.setDateOfCreation(DatatypeFactory.newInstance()
                        .newXMLGregorianCalendar(gc));

jaxb xml对象是类的私有成员var，将访问修饰符从static更改为none不会影响异常。我读到了WEB9031异常，它是由类加载器无法加载TimeZone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。但我没有共同的图书馆。我认为异常中提到的java.util.timezone类正在卸载或类似的东西。

如果有人有任何想法解决这个问题，请告诉我!!

2 个答案:

答案 0 :(得分：0)

据Oracle称，WEB9031的原因和解决方案是：

  

原因：   此问题通常表示Web应用程序的类加载器已缓存，并且正在尝试使其加载资源，即使已经取消部署类加载器的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未在Web应用程序的生命周期内缓存和使用

由于您的问题似乎是零星的，听起来这可能是一个缓存问题。就个人而言，我认为当Glassfish本身是Java应用程序的服务器时，应该没有必要让Glassfish用户在Glassfish的类路径上放置标准的Java类（java.util.TimeZone）！从控制台启动域时提及包含java.util.TimeZone的类的建议可能仅适用，因为它会将库添加回类路径。

尝试再次停止并启动域以刷新缓存。

我正面临类似的问题，重启域名似乎对我不起作用。我只是觉得我会建议你，因为它听起来并不像你试过的那样。

答案 1 :(得分：0)

执行以下步骤。

  1. 取消部署glassfish服务器中部署的所有应用程序。

  2. 停止glassfish服务器。

  3. 清除glassfish缓存。（清除以下文件夹内容）

    • $ GLASSFISH_HOME /的glassfish /域/域1 /生成/ *

    • $ GLASSFISH_HOME /的glassfish /域/域1 / OSGi的高速缓存/ *

    • $ GLASSFISH_HOME /的glassfish /域/域1 /应用/ *

  4. 现在重新启动glassfish服务器。
