在Debian系统上进行JSP（JavaServer Pages）的错误处理和调试，可以遵循以下步骤：

1. 配置Tomcat服务器

首先，确保你已经在Debian上安装并配置了Tomcat服务器。Tomcat是常用的JSP容器。

安装Tomcat

sudo apt update
sudo apt install tomcat9

启动Tomcat

sudo systemctl start tomcat9
sudo systemctl enable tomcat9

2. 配置错误页面

在Tomcat中，你可以配置自定义错误页面来处理特定的HTTP错误状态码。

编辑web.xml

找到你的Web应用程序的web.xml文件，通常位于/var/lib/tomcat9/webapps/your-app/WEB-INF/目录下。

<
    error-page>
    
    <
    error-code>
    404<
    /error-code>
    
    <
    location>
    /error404.jsp<
    /location>
    
<
    /error-page>
    
<
    error-page>
    
    <
    error-code>
    500<
    /error-code>
    
    <
    location>
    /error500.jsp<
    /location>
    
<
    /error-page>

3. 创建错误页面

在Web应用程序的/WEB-INF/目录下创建相应的错误页面文件，例如error404.jsp和error500.jsp。

<
    !-- error404.jsp -->
    
<
    %@ page contentType="text/html;
    charset=UTF-8" language="java" %>
    
<
    html>
    
<
    head>
    
    <
    title>
    Page Not Found<
    /title>
    
<
    /head>
    
<
    body>
    
    <
    h1>
    404 - Page Not Found<
    /h1>
    
    <
    p>
    The page you are looking for does not exist.<
    /p>
    
<
    /body>
    
<
    /html>
    

<
    !-- error500.jsp -->
    
<
    %@ page contentType="text/html;
    charset=UTF-8" language="java" %>
    
<
    html>
    
<
    head>
    
    <
    title>
    Internal Server Error<
    /title>
    
<
    /head>
    
<
    body>
    
    <
    h1>
    500 - Internal Server Error<
    /h1>
    
    <
    p>
    An unexpected error occurred on the server.<
    /p>
    
<
    /body>
    
<
    /html>

4. 调试JSP页面

启用JSP调试

在Tomcat的conf/context.xml文件中启用JSP调试。

<
    Context>
    
    <
    Resources className="org.apache.naming.resources.FileDirContext"
               extraResourcePaths="/WEB-INF/classes=/WEB-INF/lib"
               cachingAllowed="true"
               cacheMaxSize="102400"
               cacheTTL="60000"
               cacheTTLUnits="milliseconds"
               cacheMaxSizePerClassloader="102400"
               cacheTTLUnitsPerClassloader="milliseconds"
               cacheTTLUnitsPerClassloader="milliseconds"
               cacheTTLUnitsPerClassloader="milliseconds"
               cacheTTLUnitsPerClassloader="milliseconds"
               cacheTTLUnitsPerClassloader="milliseconds"
