I am writing a code for a plugin which will be deployed on other machines. I want to know how do we get the project path so that i can specify the access of any file (eg - an xml or a text file) with respect to this fact.
Presently i make do by writing it as -
File file = new File(System.getProperty("user.dir") + "//ListOfErrors.xml");
But this cant be used later on.
can anyone suggest me a solution to this?

A project is a development time thing. Generally at runtime you should
expect your plugin to be a jar and it's best not to assume you can
access its contents using java.io.File. You could use basic standard
Java capabilities, such as Class.getResource or
Class.getResourceAsStream, to fetch the resource relative to some class
name, i.e., you put the resource in the same folder as some class and
use that class instance to load it. Within an OSGi environment, URLs of
the form platform:/plugin/<plugin-id>/<path-in-plugin> can be used to
access resources within the plugin. FileLocator.toFileURL can be used if
you absolutely need a java.io.File, but be warned that it's not so
efficient as it will need to unzip your jarred plugin. FileLocator also
has findEntry methods you might want to use.

What do you mean by project? Do you mean plugin or the project the user is working on ? IF its plugin, then your query is already answered. If it is latter. IProject.getLocation() should give you the path.
