Question

我正在尝试使用solrJ

访问solr服务器

我在子域search.xxx.com中部署了solr并尝试使用solrj客户端索引一些数据。但是我在tomcat 7的catalina.out中收到了“需要长度”。
当我开发它时，它在我的本地设置中运行良好。
查询成功，即使返回了0个文档。
即使我转储了这个并转到数据导入处理程序（xml），我该如何动态更新文档。

下面是我得到的catalina.out错误：

org.apache.solr.common.SolrException: Length Required

这不是一个完整的答案（我无法在stackoverflow中'评论'。

似乎你的solrj请求没有被solrservlet回答，而是一个错误页面或其他东西。 search.xxx.com之前是否有网络服务器？

您可能希望从tomcat服务器的系统输出/错误日志开始，以获取服务器端异常。这会有所帮助。

需要solr长度
