Jboss image upload and HTTP access to show image--reference

Question

I am uploading images to JBoss server by getting the absolute path using the following code

getServletContext().getRealPath("");

The uploaded image is moved to the absolute path and I can access the image usinghttp://test.com:8080/image.jpg

My problem is the image was being uploaded to the TMP directory of JBoss server, so I am losing the uploaded images in the Next deployment. I tried uploading the image to various paths to make it work \jboss-5.0.1.ga\server\default\deploy and here \jboss-5.0.1.g A\server\default\work\jboss.web\localhost as well fails, I cannot access the image using HTTP://TEST.COM:8080/IMAGE.J Pg

Answer

You can add a new context to specify a path to access an external folder.

Steps for Jboss 4 and older versions:

2. Open your file /YOURINSTANCE_JBOSS/deploy/jboss-web.deployer/server.xml .

3. Define a new in the Context tag<Host name=”localhost” ...>

   Example:

     <host  Name= "localhost Span class= "pun" >...><context path = "/myfolder"  Docbase= "/home/username/my_ Images " Reloadable=" true  "></context>        

   Where /myfolder 'll be is the path that is going to use to access your files, and/home/username/my_images< /c1> the folder where you were going to upload your pictures.

5. Restart JBoss

Now you'll be able to access your files with the next path:

http://yourserver:yourport/myfolder/filename

Steps for Jboss 5:

1. Create a new file named into context.xml your WEB-INF folder with the next content:

   <?XML version="1.0"Encoding="UTF-8"?><Context Allowlinking= "true"  cookies = "true"  Crosscontext= Override= "true" >  <resources allowlinking = "true"  Classname= " Your_package. MyResources " Homedir="/home/username/my_images "  /></context< Span class= "pun" >>              

   Where ClassName is the Java class, that would access the resources and homedir your external directory.

3. According to this link create a new class to access your resources defined in the filecontext.xml

   Example:

   public class MyResources extends FileDirContext {}

Now you'll be able to access your files with the next function:

request.getServletContext().getResourceAsStream(uri);

Steps for Jboss 5 and older versions:

1. Create a new file named into context.xml your Web-inf folder with the next content:

   <?XML version="1.0"Encoding="UTF-8"?><context Allowlinking= "true"  Cookies=  "true"  Crosscontext= "true"  Override= "true" > Span class= "pun" ><resources Allowlinking=  "true"  Homedir= /> </ Context>             

   Where Homedir is your external directory.

2. Create a symbolic Link: YourDeployedProject.war/myfolder linked to/home/username/my_images

   Windows:

   mklink /D C:\YOUR_JBOSS_SERVER\server\default\deploy\YourDeployedProject.war\myfolder C:\users\YOURUSER\my_images

   Linux:

   YourDeployedProject.war# ln -s /home/username/my_images myfolder

Now you'll be able to access your files with the next path:

http://localhost:8080/DeployedProject/myfolder/filename

Steps for Jboss 7:

JBoss 7 doesn ' t allow any of the methods in the previous JBoss versions, so the easiest solution are to implement a Servle T to access your files like in the next link.

I use such a property because I do not want to hard code the local directory in the Web. As it can be different in Var IOUs deployement context.
