How to find path of my folder

Question

We are working on project. Every colleague have different folder for the install In my case the folder of my files is in

C:\\p4_3202\\CAR\\car.rt.appl\\dev\\car.components\\cars\\res\\car.rt.components.cars\\resources\\js;

for other colleague it could be in

C:\\my_3202\\CAR2\\car.rt.appl\\dev\\car.components\\cars\\res\\car.rt.components.cars\\resources\\js;

it is depends how you config your perforce.

I need to read files from my folder but i don't know the name of the folder ( as i explained it could be different )

 File folderFile = new File(folder);

How i can find the location of my folder ? ( c:\p4\......test.js ) I tried with

 System.getProperty("sun.java.command"); System.getProperty("user.home")

but it didn't give me the path of my folder

the folder that the files of the java are located in the eclipse — user1365697

I would use a system property for each user. So all users tell where perforce is installed (might already exist a property for this, look at the docs). This could then be read by your code like:

 System.getenv().get("PROP");

On a unix/Linux system you can set the property in a shell/environment variable using:

 export PROP=thepath

Windows was a long time ago for me but if I remember correctly its somewhere under System on control panel :)

When i did it String str = System.getProperty("PROP"); I got null as result

Peter Svensson Over a year ago

Did you export (or set) the property before? Otherwise null is to be expected ;)

user1365697 Over a year ago

I didn't set before when I need to set the Property

Did you read my answer? You need to set the property as a system property before accessing it. How to do this is os dependent, looking at your examples I'd guess your on windows. Updated answer with a link.

I believe he is looking for a way to find a file and read it. Using your solution, he will have access to the file he is currently reading.

The issue that the folder could be different folder in different people depends how they install the project

String path = new java.io.File(".").getCanonicalPath();

If it are files for reading only, being stored inside the final produced jar, then use URL url = getClass().getResource("/.../...") or InputStream in = getClass().getResourceAsStream("/.../...").

That uses a path inside the jar/class path. Using only the jar would never do with File.

what I will do with the result It is not possible to create File with URL
