java.io.FileNotFoundException in FileInputStream with qualified file name

Question

Getting below Error with following Code: I'm passing thefile name with full add in FileInputStream constructor. Ex-: localhost:8080/projectName/OuterFolder/InnerFloder/example.doc

logger.info("File Path: "+ path+"/OuterFolder/InnerFloder/"+fileName);

POIFSFileSystem  fs = new POIFSFileSystem(new 
                 FileInputStream(path+"/OuterFolder/InnerFloder/"+fileName));

http:\localhost:8080\projectName\OuterFolder\InnerFloder\Example.doc (The filename, directory name, or volume label syntax is incorrect)
    at java.io.FileInputStream.open(Native Method)
    at java.io.FileInputStream.<init>(Unknown Source)
    at java.io.FileInputStream.<init>(Unknown Source)

Shouldn't "Example.doc" be inside the double quotes(in the second line) ? — Shashank Kadne

path is a string variable having full path like:- localhost:8080/projectName — Avinash Mishra

@Andreas: here is the logger output- File Path: localhost:8080/projectName/OuterFolder/InnerFloder/Example.doc — Avinash Mishra

http:\localhost:8080\projectName\OuterFolder\InnerFloder\Example.doc

Is not a valid file path. On windows there is no "drive" letter "http:" like "C:". In fact I doubt, an "InnerFloder" exists too.

If you get it from a web application, use the following in:

URL url = new URL(path + "/OuterFolder/InnerFloder/Example.doc");
InputStream in = url.openStream();

To write the file somewhere (you cannot write it back to the web app http://...), select a file:

File file = new File("C:/OuterFolder/InnerFloder/" + fileName);
file.getParentFile().mkdirs(); // Create any missing directories
OutputStream out = new BufferedOutputStream(new FileOutputStream(file));
fs.writeFileSystem(out);
out.close();

This is a new file.

Shouldn't it be url.openStream()?

Avinash Mishra Over a year ago

its working @Joop but it's not working with FileWriter class

Avinash Mishra Over a year ago

@AdrianJandl: you are right. It should be url.openStream() because a static reference to the non-static method openStream() from the type URL

Same exception with FileWriter writer= new FileWriter(path+"/downloads/policies/currentASC.doc") and URL can't be use with FileWriter class.

@AdrianJandl : corrected, thanks. @Avi: with http: there need not exist any file on the file system. I have extended the answer; FileWriter (all with ...Writer/Reader) is for text, .doc is binary data and hence one needs ...Stream.

FileInputStream needs an actual file path in the file system not a URL.

It is right?? localhost:8080/projectName/OuterFolder/InnerFloder/example.doc

Andreas Fester Over a year ago

No, localhost:8080/... is not a valid local path name
