我有一个webapp的问题。请你帮我吗？ ：）
第一个错误：
2012-03-15 09：51：57.023：警告：oejs.ServletHandler：NAME_OF_WEBAPP / NAME_OF_SERVLET错误
此请求来自html页面中包含的表单。 发生此错误后，终端显示此错误：

当我编译文件WAR时，没有错误.. 我使用Jetty 7.6.0.RC4，Solr 1.4.1和Java 7 ..;）
答案 0 :(得分：1)
java.lang.ClassNotFoundException：org.apache.lucene.analysis.payloads.PayloadEncoder
这是相当自我解释的。在运行时类路径中找不到提到的类。
确保提到的类（或至少包含该类的JAR文件）位于webapp的运行时类路径中。 webapp的默认运行时类路径所涵盖的文件夹之一是webapp的/WEB-INF/lib文件夹。放下必要的JAR。
当包名称提示时，该类是Apache Lucene库的一部分。如果需要，您可以从那里下载。
