Question

Link to file outside context root of weblogic

Answer 1

+1 A:

You can use the Virtual Directory Mapping feature (that you declare in the weblogic.xml):

Using the virtual directory mapping feature, you can create one directory to serve static files such as images for multiple Web Applications. For example, you would create a mapping similar to the folowing:
<virtual-directory-mapping>
  <local-path>c:/usr/gifs</local-path>
  <url-pattern>/images/*</url-pattern>
</virtual-directory-mapping>
A request to http://localhost:7001/mywebapp/images/test.gif will cause your WebLogic Server implementation to look for the requested image at: c:/usr/gifs/images/*.

This directory must be located in the relative uri, such as "/images/test.gif".

Hi Pascal. Have you tried this before? I tried to use this one but it doesn't work. If it works for you maybe I need to config anything else?

Khue Vu 2010-03-24 06:40:25

@khue I'm aware of this feature since WebLogic 6 and I believe it would be known if it wasn't working. I'm thus tempted to think that their is a configuration mistake on your side. Maybe update the question to explain what you did exactly, show your configuration.

Hi Pascal, Thanks so much for your answer. I tried it again and it worked. Maybe I did it wrong somewhere last time.

Hi Pascal, Is there anyway we can map the different local-path to the same url-pattern? Normally the there will be error says that the MBEadn is already defined

Khue Vu 2010-03-25 05:44:37

@khue No, that's not possible and this sounds logical to me (Where should weblogic look at in that case? What if the same file exists in both location? etc).

Pascal Thivent 2010-03-25 06:06:23

My argument is that: Normally weblogic might set precedence for its search. In fact, weblogic looks at the virtual document path first then if it does not find the file, it looks at its context root. I think it can do the same for multiple local path (looks at the one defined first first) Yup, but if it is not possible, I have to find another way. So I need to define virtual-directory programmatically. I found the package: weblogic.j2ee.descriptor which contains necessary classes and method for defining it. But I can't find any documents regarding to this API. Any suggestion?

My app will need to access file from anywhere in harddisk at runtime, Previously i planed to map every drive: D:/ --> to /*; C:/ --> to /*. But as it is only one "/*" virtual path allowed. So if virtual path not work, should I use filestreaming right? I am not really clear about it.

Khue Vu 2010-03-25 06:47:36

@khue Maybe if you explain why you need that I could think of a solution. But I currently don't understand your requirement. Why don't you just put all images in one directory?

Pascal Thivent 2010-03-25 07:12:11

Hi Pascal, My web application will allow the user to browse and play media files saved in the harddisk of the server. As the files can be saved anywhere, it is required the webapp has to access different directories.

@khue I see. Is this going to run on Windows? Do you plan to use an Apache frontend? Maybe you could use symlinks. But exposing your entire disks sounds a bit weird and unsecure to be honest.

Pascal Thivent 2010-03-25 12:56:36

Thanks Pascal. I tried symlinks and it works :D. You are of so much help.

Khue Vu 2010-03-26 02:43:58

@khue You're welcome. Glad you found a solution. Maybe you could accept this answer then (the green tick below the vote counter)?

Pascal Thivent 2010-03-26 07:32:44

Yeah, I accepted it. Thanks Pascal. Sorry for late reply, I didn't receive notification.
