Get absolute path of "web content" folder in Java

Question

I want to get the absolute path of Web content folder in source code so I can retrieve another folder to upload file.

I tried ServletActionContext.getServletContext().getRealPath("images") to get the folder image in source code.

Expected result should be:

"C:\Learning\Workspace\Eclipse\boxingsaigon\WebContent\images".

But it returns me where the web was deployed:

Actual result is:

"C:\Learning\Workspace\Eclipse.metadata.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\boxingsaigon\images".

Is there any way to do this?

Answer 1

Your approach to get absolute path is right. You can get the full path by

ServletActionContext.getServletContext().getRealPath("images");   

but you get path C:\Learning\Workspace\Eclipse.metadata.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\boxingsaigon\images is the path where your actual web application is deployed.

If you change the deployed path to tomcat webapps directory that it gives you path to that directory.
you can to get the path where your actual source code is reside.

From Doc

 ServletContext.getRealPath() returns the absolute file path on the server's 
 filesystem would be served by a request for
 "http://host/contextPath/index.html", where contextPath is the 
 context path of this ServletContext..

Answer 2

You can try using this:

public String getRealFile(HttpServletRequest request, String path) {
  return request.getSession().getServletContext().getRealPath(path);
}

Hope this helps.
