Hello,

1  
2  
3  
4  
String objFilename = "/test.obj";
objFile = new File(objFilename);
fileReader = new FileReader(objFile);
bufferedReader = new BufferedReader(fileReader);


So with this is working.. but the File is in the res folder So e think I have to use something like getClass().getResource(objFilename);

but When I do that tells me "The constructor File(URL) is undefined" ... so how can I set this to work?

use InputStreams instead of Files with getResourceAsStream():

1  
2  
3  
4  
InputStream jarInputStream = getClass().getResourceAsStream(jarpath /* relative to class package */);
// I'd actually recommend this:
InputStream jarInputStream = Thread.currentThread().getContextClassLoader().getResourceAsStream(filepath);
fileReader = new FileReader(jarInputStream);


You can also convert a File into an InputStream like this:
1  
InputStream streamFromFile = new FileInputStream(new File(myfilepath));

You'd need to use the File(URI) constructor:

1  
2  
final URL url = getClass().getResource( objFilename );
final File file = new File( url.toURI() );


Probably easier to get an input-stream though:

1  
2  
final InputStream is = getClass().getResourceAsStream( objFilename );
final BufferedReader r = new BufferedReader( new InputStreamReader( is ) );

Sorry. Forgot the InputStreamReader step Smiley

(Still would recommend InputStreams instead of URI's...)
