Set Values To IWDResource

[Former Member]

Hi Experts,

I am getting File paths from Database like "C:\Invoice\Invoice1.txt"(Client Machine Path).

My Requirement is to get the file from the Path, convert into bytes & pass to RFC to store back end.

How to create IWDResource Object to read file from Client Machine. IWDResource is accepting only file content, but i have only file path.

How to get byte content of the file from client Machine?????

Please any one help me to solve this ?????

Satya.

Can you use a file upload UI and provide the client machine path (which you are getting from db) as input to this UI element by coding... i.e by setting appropriate context?

On second thoughts, why would one want to have an additional UI element to upload file to server when it is not used directly by enduser anyway... and it might not even be feasible. However there must be some way to read the file from the local path that you fetch from DB... let me get back in case I find something on this!

Hello Satya

As I understood

1. U will get filepath from db (so this file path is for client machine or server(it could be local or remote) )

2. U have to take this file parh and lookup for the content (.txt) file right (I assume client machine where app is running )

3. U have to take the content and again give it back to rfc (db).

If this is the case then internally u have to pass the file path (let say some method is there ) which will return some information of file size ,file name ,from here u can proceed .

Hi Satish,

1. I am getting file path from DB (only Client Machine paths based on IP,System Name, OS UserLogin)

2. If(f.exists()) code i will right to check file existence, but this will run on server side right. It will check in server side, but file is available in client side.

3. File Not Exists.

Satya.

Humm............

Ok , My simple question where is that content which u have to process or in simple and in your words

where is that resource exists which u have to convert into byte[].

if It is in client than see this [thread |;

for conversion of IWDResource into Byte[]

Hi Satish,

IWDResource resource = wdContext.nodeSales_Orders().getResource();

ByteArrayInputStream byteArrayInputStream = (ByteArrayInputStream)resource.read(true);

byte bytearr[] = new byte[10000];

byteArrayInputStream.read(bytearr);

Hi Satish,

IWDResource resource = wdContext.nodeSales_Orders().getResource();

ByteArrayInputStream byteArrayInputStream = (ByteArrayInputStream)resource.read(true);

byte bytearr[] = new byte[10000];

byteArrayInputStream.read(bytearr);

I don't have resource object which is pointing to my file path(C:\Invoice\Invoice1.txt). In above code Resource Object is mapped to View UI element, If you select any file from browse option then Resource object is pointing to selected file.

I don't have any UI Element to select File path, directly i have path from DB. In first Step itself not able proceed(Creating Resource Object).

Hi

here u have to provide the file path

//Taking file path from rfc and pass it to here 
File file = new File("C:\Invoice\Invoice1.txt''");

Note : Even for Upload element first we have to give the path then further it process the data.

Hi Satish,

//Taking file path from rfc and pass it to here

File file = new File("C:\Invoice\Invoice1.txt''");

if(f.exists()){

}

This code will run in server side, I won't check in client machine.(but we have client path).

Hi

I have asked some clear question that where is the resource which u have to process.

Ok let understand from one example : "D:\OLD UAM\Workspace Content\workspace.jdi\0\DCs" this is the path of my system, which contain one pdf which has solution of your problem.Now can u access this pdf from your system, can u convert into bytes & pass to RFC to store back.

U need some physical existences of the resource

So who is the client here ---web browser which runs this application.read this [Doc|; for some more input

The thread is about reading file from server.

[former_member185086]

Hi

First u can check whether file is exists or not, then u can download these content into particular node from here u can pass data to rfc.()

See code for help

IPrivateUserDataView.IUploadFileInformationElement element = wdContext.currentUploadFileInformationElement();
		if (element.getFileResource() != null)
		{
			IWDResource resource = element.getFileResource();
			if (resource.getResourceType().getFileExtension().equals("text"))
			{
				wdContext.currentUploadFileInformationElement().setFileName("File Name : " + resource.getResourceName());
				wdContext.currentUploadFileInformationElement().setFileSize("File Size : " + getFileSize(resource));
				
				try
				{
// Your Operations
                                } 
                      }
              }

About uses of IWDReso follow previous reply.

Hi Satya,

Please check this code. May be this helps you!!

IPrivatePercompView.IContextElement element = wdContext.currentContextElement();
File file = new File("\\'network\'Shared\'files\file''");
InputStream input;
int temp;
FileOutputStream op = new FileOutputStream(file);
if (element.getFileResource() != null) {
IWDResource resource = element.getFileResource();
input = wdContext.currentContextElement().getFileResource().read(false);
while((input.read())!=-1)
{
temp = input.read();
op.write(temp);
}
op.flush();
op.close();
} 
}catch(Exception e)
{
wdComponentAPI.getMessageManager().reportException(e.getMessage(),false);
}

Please let me nkow if this works.

Thanks and Reagrds

Hi Pravesh,

I don't have byte[] content, I have only file path.

I am not able to create IWDResource with file path.

What u given in that Link From Byte[] to IWDResource creation.
