JSP page resource reference problem

zhengqi888

Recently I was working on a J2EE project and encountered a strange problem with page resource references:


For example, I have the following resources:
localhost: 8080 / mydir1 / mydir2 / 1.jsp
localhost: 8080 / mydir1 / mydir2 / 2.gif
localhost: 8080 / mydir1 / images / 3.gif

Now I quote 2.gif and 3.gif inside 1.jsp
<td align = "center" background = "2.gif">
<td align = "center" background = "../ images / 3.gif">

This should be fine

But when accessed in a browser, my resources become:
localhost: 8080 / 2.gif
localhost: 8080 / images / 3.gif

Now the only solution I know is to write the full path from localhost:
<td align = "center" background = "/ mydir1 / mydir2 / 2.gif">
<td align = "center" background = "/ mydir1 / images / 3.gif">

This is troublesome, and some things ca n’t be written like this, such as jumps on the same page

localhost: 8080 / mydir1 / mydir2 / 1.jsp
Image direct INCLUDE

There are other resources, cs, js, etc. have this problem
Just go to localhost along with a jump in a page

If the image is included directly, what should I do if I jump to the same page?

> For example, jump within the same page

What do you mean?

tellyou

<a name="top"> </a>
............................

<a href="#top"> TOP </a>

The landlord, this kind of problem will not right-click on the HTML code:
<td height = "10" align = "right" colspan = "4"> <font color = "# FF6633"> <b> <a href="#top"> <font color = "# 3366CC"> Top < / font> </a> </ b> </ font> </ td>

I suggest you use
<td align = "center" background = "/ mydir1 / mydir2 / 2.gif">
<td align = "center" background = "/ mydir1 / images / 3.gif">
Way to take the path if necessary
You can use multiple methods in the request to get the path, which can achieve your requirements, but a lot of trouble.

Halo, sorry, old forum error, I replied many times yesterday, but I didn't see the result, I couldn't brush it out, and finally prompted "No more than 3 consecutive postings each time", but I saw it all today.

I will write more details
Just like the "Top" on this page, click to jump to the top of the page
http://community.csdn.net/Expert/TopicView1.asp?id=5274857#top

If it is my application, it becomes:
http://community.csdn.net/#top

All are considered to be from the application root directory, so it is very troublesome.

tellyou

Do you understand
<a name="top">
<a href="#top">

tellyou

# Is html internal positioning

Thank you all, got it done
It turned out to be the reason:
When I created a new jsp page, I used the default page with a base tag in the head:

<!-Page base URL, used when calculating relative paths->
<base href = "<% = basePath%>">

When creating a new page, the basePath is my application path, so all the resources I referenced point to the application:
<%
String path = request.getContextPath ();
String basePath = request.getScheme () + ": //" + request.getServerName () + ":" + request.getServerPort () + path + "/";
%>
