How to run an Eclipse Dynamic Web Application with Apache Tomcat Server?
提问by PhDeveloper
I tried running Apache Tomcat Server on Eclipse and got into the following problems:
我尝试在 Eclipse 上运行 Apache Tomcat Server 并遇到以下问题：
- The Catalina_Base is using a temporary location!
- I couldn't deploy the dependencies "jar files"!
- I got the following exception when running my web project:
- Catalina_Base 正在使用临时位置！
- 我无法部署依赖项“jar 文件”！
- 运行我的 Web 项目时出现以下异常：
SEVERE: Servlet.service() for servlet [jsp] in context with path [] threw exception [java.lang.AbstractMethodError: javax.servlet.jsp.JspFactory.getJspApplicationContext(Ljavax/servlet/ServletContext;)Ljavax/servlet/jsp/JspApplicationContext;] with root cause java.lang.AbstractMethodError: javax.servlet.jsp.JspFactory.getJspApplicationContext(Ljavax/servlet/ServletContext;)Ljavax/servlet/jsp/JspApplicationContext;

I managed to solve the above 3 problems by doing the following steps:
我通过执行以下步骤设法解决了上述 3 个问题：
1- Double click your server (tomcat in this case) [if you can't see it go to Windows -> Show/View -> Other -> Server -> Servers]. Your server name will look something like:
"Tomcat v7.0 Server at localhost".
1- 双击您的服务器（在本例中为 tomcat）[如果您看不到它，请转到Windows -> Show/View -> Other -> Server -> Servers]。您的服务器名称类似于：“Tomcat v7.0 Server at localhost”。
Double click the server and make sure the Server Locations is set to :
"Use Tomcat installation (takes control of Tomcat installation)".
If you can't edit the servers location:
Stop the server, right-click the server and select Publish.
If still you cant edit it:
双击服务器并确保服务器位置设置为：“使用 Tomcat 安装（控制 Tomcat 安装）”。如果您无法编辑服务器位置：停止服务器，right-click the server and select Publish. 如果仍然无法编辑它：
Right click the server --> Add and Remove and remove your project then publish it again.
右键单击服务器 --> 添加和删除并删除您的项目，然后再次发布它。
The reason for selecting "Use Tomcat installation" is that Catalina_Base will point to a temporary location and will look something like:
选择“使用 Tomcat 安装”的原因是 Catalina_Base 将指向一个临时位置，看起来像：
"-Dcatalina.base="C:\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp1"
This will cause a 404 Error even when trying to open Apache Tomcat Start Page. When selecting "Use Tomcat Installation" the Catalina_Home and Catalina_Base values will be the same and both will point to the Tomcat Installation Directory: Example:
即使在尝试打开 Apache Tomcat 起始页时，这也会导致 404 错误。选择“使用 Tomcat 安装”时，Catalina_Home 和 Catalina_Base 值将相同，并且都指向 Tomcat 安装目录：示例：
-Dcatalina.base="C:\apache-tomcat-7.0.37" -Dcatalina.home="C:\apache-tomcat-7.0.37"
To see the Arguments:
要查看参数：
Double Click the Server then click on "Open launch configuration", the values will appear in the "Arguments" tab.
双击服务器，然后单击“打开启动配置”，值将出现在“参数”选项卡中。
2- When using dependencies (ex External Jar files), make sure the files are in : Web-Inf/lib and then add them to the class-path by doing the following:
2- 使用依赖项（例如外部 Jar 文件）时，请确保文件位于：Web-Inf/lib 中，然后通过执行以下操作将它们添加到类路径中：
Right-click the project --> Build-path --> Configure Build Path Select the "Libraries" tab Click Add External JARs and select the jar files in Web-Inf/lib
右键项目--> Build-path --> Configure Build Path 选择“Libraries”选项卡点击Add External JARs，选择Web-Inf/lib中的jar文件
Next you need to deploy dependencies: To do this:
接下来您需要部署依赖项：为此：
Right-Click the project -> Properties From the left side select "Deployment Assembly" On the right hand side click Add -> Java Build Path Entries -> Next Add all the jar files your project needs.
右键单击项目 -> Properties 从左侧选择“Deployment Assembly” 在右侧单击 Add -> Java Build Path Entries -> Next 添加项目所需的所有 jar 文件。
Otherwise, you'll get a class not found exception for the used jar files.
否则，对于使用的 jar 文件，您会得到一个 class not found 异常。
3- Make sure Web-Inf/lib does not contain any jar files from Apache Tomcat, as this will cause redundancies and will give the exception above!
3- 确保 Web-Inf/lib 不包含来自 Apache Tomcat 的任何 jar 文件，因为这会导致冗余并给出上述异常！
