Question

Is there a way to read a file from a network shared location on windows?

Answer 1

In your bat file %~dp0 expands to the location of the bat file. You need that in your classpath so that java can find the class, though I don't know if it will choke on UNC path. For example:

@echo off
echo %~dp0

would output

\\host\share\dir

EDIT: %dp0 will not work if there are spaces. This is what you need in your bat file:

@echo off
set p=%~dps0
echo %p%
java -classpath %p%\jarname classname
pause

Answer 2

When using a file path in Java, make sure to escape all \ correctly when giving the full path name.

For example, if the file is on PC with IP (10.10.10.123) on a Shared folder called Addons then the full path will be:

File f = new File ("\\\\10.10.10.123\\Addons\\readme.txt");

Other than the full path, your code is throwing a ClassNotFound because you JAVA-CLASSPATH is not set properly.

Two ways of doing.

1) Map the shared path to a local drive.

2) Else hard code the server path in new File('') as mentioned by Medopal.

Something like new File("").getAbsolutePath() might help me get the base Folder when executed on a local system. Likewise there is no such way to programmatically find out the working base when executed on a shared location.
