与 WAS 7 不兼容的 neethi.jar

Question

我正在 websphere 7 中使用 neethi-3.0.2 部署一个应用程序 Apache CXF-2.7.5。我遇到以下错误。我的应用程序是弹簧驱动的。当我将 Apache CXF 降级为 apache CXF-2.3.5 时。应用程序部署成功。

同样在Tomcat7中完美运行。

通过在 pom.xml 文件中添加（或覆盖）neethi.jar（使用旧版本 --> 2.5.x）的依赖项，我能够在 Tomcat 上重现此问题。

注意： Apache CXF 2.7.5 带有最新版本的 neethi.jar (3.0.2)，因此不会在 Tomcat7 上引起问题。

Web Sphere 是否采用了旧版本的neethi.jar

堆栈跟踪如下：

请帮忙

Answer 1

我必须在 Web 模块级别加载“parent_last”类，并从 WAR 中删除以下 jar 文件：-

geronimo-servlet_3.0_spec-1.0.jar
geronimo-javamail_1.4_spec-1.7.1.jar
stax-api-1.0.1.jar

这是因为 AssertionBuilderFactory 是 2.0.5 版本的 neethi.jar 中的实现，但由于 CXF 2.7.5，我们正在使用 3.0.2 中的接口。

由于这些 jar 文件由于 CXF 依赖性而在构建时自动添加，我认为我们必须在部署到 WAS 之前从 WAR 中手动删除这些 jar。此外，每次部署时，我们都必须更改 WAR 的类加载器设置。

要更改类加载器顺序，请使用以下路径：- Enterprise Applications > MyApplicationWAR > Manage Modules > MyApplicationWAR

您可以使用<exclusions>标记从 POM 文件中执行相同操作
