How display Uploaded Image in Current Page

[Former Member]

Hi All,

What excatly my requeriment is, I need to Upload Image and display in View.

I wrote Code like this

byte []by=new byte[wdContext.currentContextElement().getResource().read(true).available()];

wdContext.currentContextElement().getResource().read(true).read(by);

wdContext.currentContextElement().setData(by);

Here getResource-- it is value Attibute. it is assined to FileUpload UI Element.

I am getting total Image data to <b>by</b> variable.

My Problem is how to display image with that byte variable(<b>by</b>).

Please give solution to this problem or give any other solutions........

Thanks

Hallo Satya,

the following solution is only applicable in NW 04s:

<b>Context Definition</b>

Node:Resource

|_ Attribute: <i>UploadImgResource </i>: Resource

|_ Attribute: <i>UploadImgURL</i> : String

<b>View Layout</b>

FileUpload-resource -> bound to context attribute <i>UploadImgResource</i>

Image-source -> bound to context attribute <i>UploadImgURL</i>

<b>View Controller Coding</b>

//@@begin javadoc:onActionUploadImg(ServerEvent)
/** Declared validating event handler. */
//@@end
public void onActionUploadImg(
  com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent, 
  com.sap.tc.wd.tut.fileupdownload.comp.wdp
    .IPrivateTableView.IResourcesElement resourceElement )
{
  //@@begin onActionUploadImg(ServerEvent)
  //  if a file in the FileUpload field exists
  if (resourceElement.getUploadImgResource() != null) {
    // copy URL string from IWDResource object to 
    // context attribute 'UploadImgURL'. Image gets 
    // visible on the UI based on data binding definition.  
    resourceElement.setUploadImgURL(
      resourceElement.getUploadImgResource().getUrl(
        WDFileDownloadBehaviour.OPEN_INPLACE.ordinal()));
  }
  //@@end
}

Hi,

The Image control requires a file name of the image in source property,

the file should be in your mimes of your project.

You can create a file and place it in the mimes folder and give the name of the

file in the source property

This is not the preferred solution, but you can try it.
