Question

我尝试创建HtmlUnit WebClient以解析Servlet filter服务器上Java EE Glassfish内的Ember应用网页。

servlet代码：

  final WebClient webClient = new WebClient(); // causes error
  HtmlPage page = webClient.getPage(originalUrl);

的pom.xml

错误：

java.lang.NoSuchMethodError: org.apache.http.impl.cookie.BrowserCompatSpecFactory.create(Lorg/apache/http/protocol/HttpContext;)Lorg/apache/http/cookie/CookieSpec;

Answer 1

显然将HtmlUnit依赖项移动到依赖项列表的底部修复了该问题。就像提到的peeskillet一样，这不是一个完整的解决方案，因为我们仍然不知道是什么原因引起了这个问题，但它可以作为第一个解决方案。如果你找到了罪魁祸首，请回答。

Answer 2

我有同样的错误，但html单位不是解决方案。我将httpclient.jar放到顶部，以解决问题。

尝试在Glassfish上创建WebClient时出现NoSuchMethodError
