Accessing an Image dynamically from specified folder on server

[Former Member]

The project is about keeping track of employee records.Each employee has a image.These images are saved on the server at a specified location i.e. <b>c:\images\</b>.This path along with other details are saved in the database.

While viewing the details of the employee in another view, his/her image should be displayed.

So my question is how to set image to the image UI Element?

HI Sowmya,

Let the image source variable be <b>"Img".</b>

Here I am assuming that u want to display Sowmya.jpg from C:\Images in server.

Do the following.

File f=new File("C:
Images
Sowmya.jpg");//File name is Case sensitive

FileInputStream fis=new FileInputStream(f);

byte b[]=new byte[fis.available()];

fis.read(b);

IWDResource res=WDResourceFactory.createCachedResource(b,"Sowmya.gif",WDWebResourceType.UNKNOWN);

String url=res.getUrl(1);//GETTING URL OF IMAGE FROM SERVER

wdContext.currentContextElement().setImg(r);//SETTING IMAGE SOURCE

You must put the images in a folder that is accessible via the Web AS or put them into a deployment unit. In either case, the Image UI element needs the URL to the image as value of its "source" property.

I tried doing it but what happens is, it is picking up image from my local system and not from the server. As I already mentioned that the images are on the server at location C:\images

Hi Sowmya,

Add two value attributes ( ImgSource) to

the value node for image.Make it calculated.In getter u can access the employee id or other details & set the source accordingly(Any how u r goin to get the source from the database.
