Unable to get the filename from file upload UI element

[narayani_krishnamoorthy]

Hi,

I added a FileUpload UI element.

I created an attribute of type resource , assigned to the resource property of the file upload element.

I created an action button called upload and added the following code.

try {

IWDResource resource = wdContext.currentContextElement().getFileupload();

} catch (Exception e) {

e.printStackTrace();

}

when I debug to see the value of resource it is null.

Please let me know where I am going wrong.

Regards,

Hi Narayani,

Please go to the followinf code. This code take the Resource object and bind it to the respective resouce.

Hope this will help you.

try{

String path = WDURLGenerator.getResourcePath(wdComponentAPI.getDeployableObjectPart(),"LocalConveyance.pdf"); // gets the path of local object.

try{

InputStream stream = new FileInputStream(path);

IWDResource LocalConveyanceResource = WDResourceFactory.createResource(stream, "LocalConveyance.pdf", WDWebResourceType.PDF, true);

wdContext.currentContextElement().setLocalConveyanceTarget(LocalConveyanceResource); //LocalConveyanceTarget is the context with type RESOURCE.

wdContext.currentContextElement().getLocalConveyanceTarget();

}

catch(IOException b)

{

b.getMessage();

}

}

catch(WDAliasResolvingException e)

{

e.getMessage();

}

Hi

Which version of NWDS are you using ?

try{

IWDResource resource = wdContext.currentContextElement().getFileupload();

if(resource() != null)

wdComponentAPI.getMessageManager().reportSuccess(resource.getResourceName());

else{w

dComponentAPI.getMessageManager().reportWarning("Please upload the Document ");

}

} catch (Exception e) {

dComponentAPI.getMessageManager().reportWarning(e.getMessage());

}

Hi Narayani,

What type of file are you trying to upload? Is that an XML file? Can you try checking the other file formats like word, excel, etc...

Check this:

// Appendix is the context node

IPrivateFreightRequestComponentView.IAppendixElement

element = wdContext.currentAppendixElement();

// if a file in the FileUpload field exists

if (element.getUploadFile() != null)

{

IWDResource resource = element.getUploadFile();

// get the size of the uploaded file => separate method

element.setFileSize(this.getFileSize(resource));

<b>// get the extension of the uploaded file

element.setFileExtension( resource.getResourceType().getFileExtension());</b>

// set context attribute 'fileName' .

element.setFileName(resource.getResourceName());

// set the details visibility attribute

element.setDetailsVisibility(WDVisibility.VISIBLE);

}

else

{

// if no file in the FileUpload field exists

}

Hi,

Check if there are any space characters in your uploading path (file path).

First try to upload a file without any space characters in the uploading path(file path). If the problem is with the space characters then use the below encoding & decoding to resolve that issue.

Encoding while uploading the file:

// Getting the file resource
IWDResource resource = element.getCtx_va_FileResource();
//Getting the resource name
String resourceName = resource.getResourceName();
//Encoding the resource name
String encoderesourceName = java.net.URLEncoder.encode(resourceName,"UTF-8");

Again while downloading you can use decoder.

Hope this helps to resolve your issue.

See this below link.

Try this encoding even if there are no space characters.

Hi Narayani,

Can you try printing the catch block to the Web Dynpro view?

Also check if the view controller's fileupload attribute is mapped to the component controllers fileupload attribute.

Hi,

The data property will be the first property of FileUpload UI.
