Java JSP-只能导入类型。Name.pacakge.class解析为一个包，但该类存在

我在尝试通过tomcat 7部署webapp时收到此错误

jsp文件名

analysis.jsp

，这是错误：

以下是jsp的导入部分：

<%@ page language = "java"
    import = "java.lang.StringBuilder"
    import = "java.io.StringWriter"
    import = "java.io.PrintWriter"
    import = "java.io.ByteArrayInputStream"
    import = "java.io.IOException"
    import = "java.io.File"
    import = "java.io.BufferedReader"
    import = "java.io.InputStreamReader"
    import = "java.io.InputStream"
    import = "java.nio.file.Files"
    import = "java.nio.file.Paths"
    import = "java.nio.file.StandardCopyOption"
    import = "mila.HMM.MorphMult2TaggerFormat"
    import = "mila.HMM.HMM2Morph"
    import = "mila.mw.PostProcessor1"
    import = "mila.mw.MWXMLTokenizer"
%>

正如您所看到的，jar确实包含了我需要的所有类，但由于某种原因，jsp文件无法将它们识别为类

另外，没有其他类名称相同的包（即所有类名称在整个项目中都是唯一的）

---

我做错了什么？请提供帮助。

类在导入属性中用逗号分隔

如下图所示：

---

import=“mila.HMM.MorphMult2TaggerFormat，mila.HMM.HMM2Morph，mila.mw.PostProcessor1，mila.mw.MWXMLTokenizer”

在应用程序的类路径中包含

morphAnalyzer.jar

，回答了建议重新启动Tomcat的类似问题，请参见此处：我尝试过它。取消部署服务，重新启动tomcat，尝试重新部署，但得到了相同的错误：（因此我应该将所有导入更改为类似于

import=“class1，class2，class3，…”

？不幸的是，这不起作用，我也尝试重新启动tomcat。您添加了吗“mila.HMM.MorphMult2TaggerFormat，mila.HMM.HMM2Morph，mila.mw.PostProcessor1，mila.mw.MWXMLTokenizer”在您的导入语句的第一个中？如果没有，请在第一个中添加它们。没有，它们在它的末尾。这有什么区别吗？（现在尝试替换它们）。并在重新启动之前删除tomcat中的工作目录。对于noob问题，很抱歉，但我该怎么做？这个JAR基本上是我的整个应用程序。如果你正在构建桌面应用程序，那么你的项目应该压缩到JAR。对于web应用程序，它应该压缩到.war。在这个war中，在web-INF/lib文件夹下的其他库中，你的app引用应该驻留。I eclipse您可以配置这些jar文件的路径，以便在生成war文件时将其捆绑并在编译时识别。我正在远程Linux工作站（我的电脑是windows）上工作，该应用程序是针对internet的。我要做的是创建一个jar文件（

morphAnalayzer.jar

）使用eclipse导出它（将引用的库捆绑在一起），并将其放入

WEB-INF\lib

文件夹中（通过SSH到工作站），然后尝试从tomcat manager（在我的PC上）部署它通过将其定向到文件夹。我可以从整个事件中生成一个

.war

文件，并从家里用tomcat manager上传它，这会有同样的效果吗？在您使用SSH上传jar文件后。不要在tomcat manager中部署。只需重新启动服务器。如果您在不创建war的情况下进行部署，您将失去上传所做的更改使用SSHHey很抱歉延迟回复这里有2周的假期。我不明白您的确切意思-该服务目前已完全取消部署。我是否应该重新部署它？在我的windows工作站上创建一个WAR文件并部署所述文件？
