简短版

制作玻璃鱼的选项是什么选择在其通用 500服务器错误中包含堆栈跟踪 page：

asp.net中的长版本

您可以通过在web.config xml文件中设置一个值来包含堆栈跟踪：

web.config < /strong>：

<configuration>
   <system.web>
      <customErrors mode="Off" />
   </system.web>
</configuration>

这会导致页面显示错误的堆栈跟踪：

什么是等效的Jakartaee/Glassfish选项？

现在死亡的灰色屏幕没有显示堆栈跟踪：

情况

jakarta-ee中的机制是什么，以注册全球无人教的例外处理程序，所以我可以自己显示堆栈跟踪？

在ASP.NET中，您进入您的 global.asax 文件，然后输入application_error回调的代码：

global.asax ：

    void Application_Error(object sender, EventArgs e)
    {
        // Code that runs when an unhandled error occurs

        // Get the exception object.
        Exception exc = Server.GetLastError().GetBaseException();

        WriteCustomYellowScreenOfDeath(Response, exc);

       // Clear the error from the server
       Server.ClearError();
    }

什么是java/是什么Java-ee/jakarta-ee/Glassfish等效？

Short Version

What's the option to make Glassfish include a stack trace in its generic 500 Server Error page:

Long Version

In ASP.net you can have the generic error page include a stack trace by setting a value in your web.config xml file:

web.config:

<configuration>
   <system.web>
      <customErrors mode="Off" />
   </system.web>
</configuration>

This causes the page to show the stack trace of the error:

What is the equivalent JakartaEE/Glassfish option?

Right now the gray screen of death doesn't show a stack trace:

Alternatively

What is the mechanism in Jakarta-EE to register a global uncaught exception handler, so i can display a stack trace myself?

In ASP.net you go into your global.asax file, and enter code for the Application_Error callback:

Global.asax:

    void Application_Error(object sender, EventArgs e)
    {
        // Code that runs when an unhandled error occurs

        // Get the exception object.
        Exception exc = Server.GetLastError().GetBaseException();

        WriteCustomYellowScreenOfDeath(Response, exc);

       // Clear the error from the server
       Server.ClearError();
    }

What's the Java/Java-EE/Jakarta-EE/Glassfish equivalent?

首先，您通过在web.xml中指定它来告诉网络服务器，您想向我们提供一个自定义错误页面：

web.xml ：

<web-app>
    <!-- Any unhandled (i.e. Throwable) errors, display the page ysod.jsp (rather than the built-in default -->
    <error-page>
        <exception-type>java.lang.Throwable</exception-type>
        <location>/ysod.jsp</location>
    </error-page>
</web-app>

然后您创建一个新的new < em>死亡的黄色屏幕 jsp文件：

ysod.jsp

<!DOCTYPE html>
<%@page import="java.io.PrintWriter"%>
<%@page import="java.io.StringWriter"%>
<%@page import="java.io.StringWriter"%>

    {
        //Java does not have any htmlEncode or escapeHtml (https://stackoverflow.com/a/1400705/12597)
        return s;
    }
%>

<%
    Throwable cause = exception;
    while (cause.getCause() != null)
    {
        cause = cause.getCause();
    }

    String path = "/";
    String message = cause.getMessage(); //e.g ."Division by zero error";
    String exceptionClassName = exception.getClass().getName(); // e.g. "EOverflow";
    String sourceFile = "$(sourceFile:C:\\website\\WebSite\\src\\FrobTheGrobber.java)";
    String sourceLine = "$(sourceLine:619)";
    String serverInfo = getServletContext().getServerInfo().trim(); //e.g. "Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.34209"
    String javaVersion = System.getProperty("java.version");

    StringWriter sw = new StringWriter();
    exception.printStackTrace(new PrintWriter(sw));
    String stackTrace = sw.toString();

    StackTraceElement[] stes = exception.getStackTrace();
    if (stes.length > 0)
    {
        StackTraceElement st = stes[0];
        sourceFile = st.getFileName();
        sourceLine = Integer.valueOf(st.getLineNumber()).toString();
    }

和鲍勃的叔叔 - a 有用错误页面：

First you tell the web-server that you want to us a custom error page by specifying it in your web.xml:

web.xml:

<web-app>
    <!-- Any unhandled (i.e. Throwable) errors, display the page ysod.jsp (rather than the built-in default -->
    <error-page>
        <exception-type>java.lang.Throwable</exception-type>
        <location>/ysod.jsp</location>
    </error-page>
</web-app>

And then you create a new Yellow Screen of Death JSP file:

ysod.jsp

<!DOCTYPE html>
<%@page import="java.io.PrintWriter"%>
<%@page import="java.io.StringWriter"%>
<%@page import="java.io.StringWriter"%>
<%@page isErrorPage="true" %>

    public String htmlEncode(String s)
    {
        //Java does not have any htmlEncode or escapeHtml (https://stackoverflow.com/a/1400705/12597)
        return s;
    }
%>

<%
    Throwable cause = exception;
    while (cause.getCause() != null)
    {
        cause = cause.getCause();
    }

    String path = "/";
    String message = cause.getMessage(); //e.g ."Division by zero error";
    String exceptionClassName = exception.getClass().getName(); // e.g. "EOverflow";
    String sourceFile = "$(sourceFile:C:\\website\\WebSite\\src\\FrobTheGrobber.java)";
    String sourceLine = "$(sourceLine:619)";
    String serverInfo = getServletContext().getServerInfo().trim(); //e.g. "Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.34209"
    String javaVersion = System.getProperty("java.version");

    StringWriter sw = new StringWriter();
    exception.printStackTrace(new PrintWriter(sw));
    String stackTrace = sw.toString();

    StackTraceElement[] stes = exception.getStackTrace();
    if (stes.length > 0)
    {
        StackTraceElement st = stes[0];
        sourceFile = st.getFileName();
        sourceLine = Integer.valueOf(st.getLineNumber()).toString();
    }
