Why my imports are not recognized

提问by Bohn

Using EClipse, First: I created a Dynamic Web Project and copied soem JAR files ( Jersey Jar files ) to WebContent\WEB-INF\lib folder of that project.

使用 EClipse,首先:我创建了一个动态 Web 项目并将 soem JAR 文件(Jersey Jar 文件)复制到该项目的 WebContent\WEB-INF\lib 文件夹中。

Then I created a new class and on top of it I used some imports such as these:

然后我创建了一个新类,在它之上我使用了一些导入,例如:

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

but it shows some red X errors next to all of them saying the import cannot be resolved.

但它在所有这些错误旁边都显示了一些红色 X 错误,表示无法解析导入。

That's ALL I have done. Is there any other settings I should do to fix these errors?

这就是我所做的一切。我应该做任何其他设置来修复这些错误吗?

Additional information for Jersey newbies: Those imports come from javax.ws.rs-api-2.0.jar, which is found in the "api" directory in the Jersey download, not in the "lib" directory with the jersey-*.jar jars.

Jersey 新手的附加信息:这些导入来自 javax.ws.rs-api-2.0.jar,它位于 Jersey 下载的“api”目录中,而不是在带有 jersey-*.jar 的“lib”目录中罐子。

First, make sure you ran "refresh" on the project. If that doesn't pick up the JARs then navigate to them in Eclipse's Project Explorer, right-click on them and in the popup menu use "Build Path" > "Add to Build Path".

首先,确保您对项目运行了“刷新”。如果没有找到 JAR,则在 Eclipse 的项目资源管理器中导航到它们,右键单击它们并在弹出菜单中使用“构建路径”>“添加到构建路径”。
