Access to the class of documents absolute path

  In java, often positioning the location of certain documents, in order to allow procedures and physical location irrelevant to the use of a relative path.    However, the use of a relative path java always encountered some very troublesome issues, which is in the end of reference for the issue.    Because we usually use a relative path is always relative in terms of the current working directory, but sometimes demand is not the case.    For example, in a development kit used in the relative path, but do not know development kits by other procedures at the time of call of the path, and particularly in the web application, it is difficult to establish a file in the application of a relative path. 

  Therefore, the use of a relative path is the best way to the relative reference is the path of my development kits or my application itself things, the best thing is to use my development kits in the class of documents.    Know if a certain class of documents absolute path, we can take it for reference, the use of a relative path to locate any other documents. 

  </ Td> </ tr> </ table> 

  In order to achieve this idea, and I wrote this Path class that provides two public static methods, such as positioning for a class file, and another to a certain category is the reference to locate a relative path.    Use of the two methods, we can not totally ignore the work of the current path, according to their own arbitrary location to find any documents.    For example, in the preparation of a functional development kit, it could not complete the call of the application development kits path, but only under development kits positioning itself to the position paper, the realization of such a good package, the documents be fully closed in the path of the development kits of their own.
