See following example to get the real server file path via servletRequest.getRealPath("/"). However, warning is prompt and complained that this method is deprecated.

import javax.servlet.http.HttpServletRequest;

public class DisplayAction  {

	private HttpServletRequest servletRequest;
	
	public String execute() {	
		//The method getRealPath(String) from the type ServletRequest is deprecated 
		String filePath = servletRequest.getRealPath("/");
	}
	
	@Override
	public void setServletRequest(HttpServletRequest arg0) {
		this.servletRequest = arg0;
	}

}

Instead, you should use servletRequest.getSession().getServletContext().getRealPath("/") (refer to the end of the reference site for detail). See updated example again.

import javax.servlet.http.HttpServletRequest;

public class DisplayAction  {

	private HttpServletRequest servletRequest;
	
	public String execute() {	
		servletRequest.getSession().getServletContext().getRealPath("/");
	}
	
	@Override
	public void setServletRequest(HttpServletRequest arg0) {
		this.servletRequest = arg0;
	}

}
