使用jsp在服务器上运行时找不到路径 [英] fail to find the path when running on the server using jsp
问题描述
下面的所有代码都是用jsp编写的.当我启动服务器时，它应该警告json类型.当我不在服务器上运行以下代码时，它实际上可以工作.我怀疑文件路径是否存在问题. data.json的路径为 C:\ Users \ fujimaro \ Desktop \ data.json ，否则我不知道可能出了什么问题.
All the code below are written in jsp. When I start the server, it should alert the json type. When I run the code below not on the server, it actually works. I suspect if is there something wrong with my file path. The the path of the data.json is C:\Users\fujimaro\Desktop\data.json , otherwise I have no clue what could be wrong.

推荐答案
在您的JSP(将其命名为showJson.jsp)中，您将像这样加载javascript.js和data.json:
In your JSP (lets name it showJson.jsp) you loads javascript.js and data.json like this:
<script type="text/javascript" src="javascript.js"></script>
<script type="text/javascript" src="data.json"></script>
在src中，您直接提供文件名而没有前缀.
因此， data.json，javascript.js和您的showJson.jsp应该位于同一文件夹中.
In the src you give the filenames directly without prefix.
Therefore the data.json, javascript.js and your showJson.jsp should be in the same folder.
glassfish 4(java ee)中的项目结构如下:
The project structure in glassfish 4 (java ee) look like this:
当文件直接位于WebContent-文件夹中时，可以使用以下网址进行访问:
When the files are directly in WebContent-Folder, they can be access with these urls:
- http://localhost:8080/projectName/showJson.jsp
- http://localhost:8080/projectName/data.json
- http://localhost:8080/projectName/javascript.js
- http://localhost:8080/projectName/showJson.jsp
- http://localhost:8080/projectName/data.json
- http://localhost:8080/projectName/javascript.js
但是应该先部署它们.部署基本上是在创建 Web存档文件projectName.war并将其移入特定的服务器文件夹.即:
But they should be first deployed. The deployment is basically creating an Web Archive file projectName.war and moving it in a specific server folder. i.e.:
C:\ glassfish4 \ glassfish \ domains \ domain1 \ applications \ domain1
C:\glassfish4\glassfish\domains\domain1\applications\domain1
在大多数情况下，此projectName.war将提取为:
This projectName.war will be (in most cases) extracted to:
C:\ glassfish4 \ glassfish \ domains \ domain1 \ applications \ domain1 \ projectName_war
C:\glassfish4\glassfish\domains\domain1\applications\domain1\projectName_war
