在我的jsp-generate页面中显示简单的图像

This question may betray my total lack of understanding, so be it, I guess. Trying the following code to display an image once the JSP page is running on Tomcat. Note, it's the tag that isn't working for me:

这个问题可能会背叛我完全缺乏理解,所以不管怎样,我猜。在Tomcat上运行JSP页面后,尝试以下代码来显示图像。注意,这是不适合我的标签:

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>George Brown GeoQuest - Welcome</title>
</head>
<body>
<img alt="logo" src="WebContent/GBGeoQuestLogo.gif">

</br>
<h1>Welcome, GB Geoquest Team!</h1>
<form action="/Lab4">
    <label>Team Name:
        <input type="text" name="name">
    </label><br>
    <input type="submit" value="Login">
    <input type="reset" value="Reset">
</form>
</body>
</html>

All I get is the blue image question-mark symbol in the top left instead of my image. Link should be viewable here: http://postimage.org/image/drnl831pz/

我得到的只是左上角的蓝色图像问号符号而不是我的图像。链接应该可以在这里查看:http://postimage.org/image/drnl831pz/

Can anyone steer me in the right direction?

任何人都可以引导我朝着正确的方向前进吗?

First you need to confirm that the image file is in the war file. Once you're sure it's there try removing the "WebContent" from the url in the JSP

首先,您需要确认图像文件是否在war文件中。一旦你确定它在那里尝试从JSP中的url中删除“WebContent”

#2

The value of the src-attribute is missing the context of the application. Now the hostname is used as the context root, so browser uses the wrong url, e.g. http://localhost:8080/WebContent/GBGeoQuestLogo.gif

src-attribute的值缺少应用程序的上下文。现在主机名用作上下文根,因此浏览器使用错误的URL,例如HTTP://本地主机:8080 /的WebContent / GBGeoQuestLogo.gif

Add the context root to the src attribute and the image will be loaded, assuming 1) it's inside the war 2) it's located in WebContent-directory in the war:

将上下文根添加到src属性并加载图像,假设1)它在战争中2)它位于战争中的WebContent目录中:

src="${pageContext.request.contextPath}/WebContent/GBGeoQuestLogo.gif"

I think your context path is Lab4/WebContent and your image is in WebContent. So in this case you can get image by,

我认为您的上下文路径是Lab4 / WebContent,您的图像位于WebContent中。所以在这种情况下你可以得到图像,

src="${pageContext.request.contextPath}/GBGeoQuestLogo.gif"

It will search image in WebContent because your Context path is Lab4/WebContent. If still have problem than in browser View Pagesource and verify the Image path

它将在WebContent中搜索图像,因为您的上下文路径是Lab4 / WebContent。如果仍然有问题,请在浏览器View Pagesource中验证图像路径

Thank you
