How to find path of a file in WebDynPro Application

[aayush_dubey3]

Hello,

I have created a WebDynPro application. In this application i have created an XML file under

src->packages->resources. The resources folder i created myself.

I have also deployed the file on a remote server. This servername & portNumber can change too.

Now i want to get the handle of my XML file (which is present in the same jar) so that i can user it and populate it.

<b>The following code doesnt work:</b>

<i>File file =new File("WebDynProProjectName/resources/filename.xml");</i>

Regards,

I am following the instructions for adding just a txt file to src\mimes\Components\<Component name>\file.txt and when i try to create a new File(file.txt) I get a FileNotFoundException. Why?

Thanks...

The constructor new File("file.txt") throws a FileNotFoundException? Don't think so.

Can you please post your code?

sorry what i meant was using FileReader(file.txt). this is what the actual code looks like. Nothing exciting just trying to get the file:

FileReader fr;

try

{

fr = new FileReader("deviceTypes.txt");

BufferedReader br = new BufferedReader(fr);

String type = br.readLine();

while(type != null)

{

type = br.readLine();

}

}

catch(FileNotFoundException fnfe)

{

}

What is the output of

File file = new File("deviceTypes.txt");
wdComponentAPI.getMessageManager().reportSuccess(file.getAbsolutePath());

assuming you are calling this from within a controller method.

i'm calling this in a view actually. this is what i get back when i catch the exception and call getAbsolutePath(): "Exception: deviceTypes.txt (The system cannot find the file specified)FilePath: C:\usr\sap\WHE\JC00\j2ee\cluster\server0\deviceTypes.txt"

[Former Member]

Ok. If you use

String path = WDURLGenerator.getResourcePath
(
  wdComponentAPI.getDeployableObjectPart(),
  "deviceTypes.txt"
);
wdComponentAPI.getMessageManager().reportSuccess(path);

what do you get?

What is the location of your file on the server?

this is what i get:

.\temp\webdynpro\web\local\xDemo\Components\xdemo.TestApp_WD\deviceTypes.txt

but, if i actually pass it the path it works though and when i just pass deviceTypes.txt it doesn't.

try

{

String path = WDURLGenerator.getResourcePath

(wdComponentAPI.getDeployableObjectPart(),

"deviceTypes.txt");

FileReader fr = new FileReader(path);

BufferedReader br = new BufferedReader(fr);

String type = br.readLine();

...

}

Have a look at the WDURLGenerator API.

Hi Aayush,

You can place your all required external files in src/mimes/components/<comp name>.

For this oopen the node src in webdynpro explorer and follow the above path. then right click on your component under this path and choose import files.

Then choose your XML file.

It will export this file in your component folder.

And now from your code you need not to give any explicit path or relative path to this file.

Only you need to give file name, thats it.

Let me know whether it qworks for you or not.

Thanks Anilkumar, Bhavik,

Will try today and let you know if it solves the problem.

Hi Aayush ,

1. Copy the file under Project/Src/Mimes/Components/<<ComponentName>>/Test.xml

2. Read the file using File file =new File("Test.xml");

This should solve the problem.

Hi

By default it puts it under resources folder. If you want to create your own path then

1. Create the XML file (eg. output.xml) to some location in the server (eg: c:\Test\files)

2. Create a HTTP alias(eg. Test) in the Visual Adminsitrator pointing to the file location (eg: c:\Test\files).

3. Set the linkToURL reference property to http://<<servername>>:50000/Test/<<XML file name>>

For creating the HTTP alias refer to the blog "Creating an HTTP Alias in WAS"

/people/renjith.andrews/blog/2005/03/31/creating-an-http-alias-in-was

Hope this solves your problem.

Hello Ravi,

Thanks. But this does not solves my problem :-(.

As of now i am just creating the project and building it in my development environment. I do not know about the runtime environment details as of now.

I can make it run only on 1 server using HTTP alias but i want to ensure that my utility (jar file) when deployed on any server uses the XML file packed with it.
