Java - Get server absolute path

How to get the absolute path of server location in my machine?

Suppose I am using glassfish server then I need to get absolute path of glassfish docroot location as below:

C:\glassfish3\glassfish\domains\domain1\docroot

At run time, I need to create file on that location using java io package like:

C:\glassfish3\glassfish\domains\domain1\docroot\myfile.txt

If you use GlassFish to start GlassFish, i.e. use asadmin start-domain|start-instance then we offer the following iron-clad guarantee:

The current working directory of the JVM is absolutely, positively guaranteed to be the config directory of the domain or server. In the default case that would be:

c:/glassfish3/glassfish/domains/domain1/config

If you want to write something to (the default) docroot, you can do this:

File f = new File("../docroot/yourfile");

Another option that is guaranteed to always work in every scenario even if you start the server with java directly (e.g. java -jar glassfish.jar) is to use the value of the System Property like so:

File f = new File(System.getProperty("com.sun.aas.instanceRoot") + "/docroot/yourfile");

I had an similar problem and ended up with using

path = getClass().getProtectionDomain().getCodeSource().getLocation()

because I needed the path on a static function. This points somwhere to the WEB-INF/classes directory. With this you could point to something like path.subString(0,path.indexOf("WEB-INF")).

One problem that I had with this: When running a test from Eclipse, it pointed me to the "build" directory of the project.

you can try following:

System.getProperty("catalina.base");

And you can find other properties by watching following variable in debug mode.

Properties properties = System.getProperties();

I don't know if this is the best way, but it works for me :)

String path = new File("").getAbsolutePath() + File.separator + "docroot";

This is a very bad idea. If you are running in a WAR or EAR file the docroot will not be on a writable filesystem. Assuming this is the case may lead to headaches later.

Use a different method, such as a servlet initialization parameter, to specify a writable filesystem location.

For that you need not to go for complete path because

when you are creating file than by default it will create at ROOT of you server

which is C:\glassfish3\glassfish\ here.

hope this will help you.
