通过复制到webapps手动部署Tomcat应用程序
[英]Manual deployment of Tomcat app by copying to webapps
问题描述
I'm trying to deploy a Tomcat application by copying it to the webapps directory. 
我正在尝试通过将Tomcat应用程序复制到webapps目录来部署它。 My webapps directory looks like: 我的webapps目录如下所示：
webapps/test
|_ index.jsp
|_ WEB-INF
|_ lib
|_ test.jar
The contents of index.jsp are: index.jsp的内容是：
<html>
Test App<br>
<%= com.stevekuo.Test.test() %>
</htm>
test.jar has the Test class with the static test() method that just returns a string. test.jar具有带有静态test()方法的Test类，该方法仅返回一个字符串。
When I access my app via http://tomcatserver:8080/test/ , all I get is: 当我通过http://tomcatserver:8080/test/访问我的应用程序时，我得到的是：
HTTP Status 500 -
type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.
exception
org.apache.jasper.JasperException: Unable to compile class for JSP:
An error occurred at line: 3 in the jsp file: /index.jsp
com.stevekuo.Test cannot be resolved to a type
1: <html>
2: Test<br>
3: <%= com.stevekuo.Test.test() %>
4: </html>
I've also tried packaging the above directory structure into a WAR file and copying to webapps , but it still gives the same error. 我也尝试将上述目录结构打包到WAR文件中并复制到webapps ，但仍然会出现相同的错误。
I'm running standard out-of-the-box Tomcat 6 on Ubuntu 10.04. 我正在Ubuntu 10.04上运行标准的现成的Tomcat 6。 Tomcat came installed by Ubuntu. Tomcat是由Ubuntu安装的。 All files have -rw-r--r-- permissions, and directories are drwxr-xr-x . 所有文件都具有-rw-r--r--权限，目录为drwxr-xr-x 。 Why can't Tomcat resolve the Test class located in WEB-INF/lib/test.jar ? Tomcat为什么无法解析WEB-INF/lib/test.jar的Test类？

have you imported com.stevekuo.Test you need to say <%@ page import="com.stevekuo.Test"%> 您是否已导入com.stevekuo.Test您需要说<%@ page import="com.stevekuo.Test"%>
this is most definitely the fault. 这绝对是错误。

Resolved. 解决。 I added an empty web.xml and it works. 我添加了一个空的web.xml ，它可以工作。
