java ee - how to obtain the relative path of a resource in a j2ee project -

-

I have a dynamic web project (or text file) with a successful file I have created a servlet in which I Need to use

My code is as follows: 

  Secure zero code (HTTPSvette request), servlet throws excitation, IOException {// string processing = request.getParameter ("Jason") ; If (resource! = Null & amp;! Resources.equals ("")) {// use getResourceAsStream () to use the file properly, InputStream = getServletContext () .getResourceAsStream ("JSON" "); If (is! = Zero) {// resource is present.setContentType ("application / json"); Response.setHeader ("Pagera", "No-Cash"); Response.setDateHeader ("End", 0); Response.setHeader ("cache-control", "no-cache"); Stringwright SW = new stringwriter (); (Int c = is.read (); c! = -1; c = is.read ()) {sw.write (c); } PrintWriter out = response.getWriter (); outside. Print (sw.toString ()); Out.flush (); }}

}

The problem is that InputStream is a zero value.

How do I get the right relative path I am using jeunes as an eb server.

I have added a resource file to the WebContent directory of a dynamic web project. As a different perspective, I tried to do this: 

  Protects Zero doGet (HTTPPervelate Request Request, HTTPSvette Response Response), Servlet Upption throws, IOException {// TODO auto generated method Stub ServletConfig config = getServletConfig (); String reference name = config.getInitParameter ("ApplicationName"); System.out.println ("context name" + reference name); String referencepath = config.getServletContext (). GetRealPath (reference name); System.out.println ("Reference Path" + Reference); // contextPath = contextPath.substring (0, contextPath.indexOf (reference name)); References + = "\\ JSONTX"; Println (contextPath); String processing = request.getParameter ("Jason"); System.out.println ("Hi is 1" + resource); If (resource! = Null & amp; resource.exe ("")) {System.out.println ("hi there"); // Get GetResourceAsStream () to get the file properly. // InputStream = getServletContext () .getResourceAsStream (resource); InputStream = getServletConfig () GetServletContext (). GetResourceAsStream (textText); If (is! = Null) {// resource exists system.out.println ("Hi is 2"); Response.setContentType ("application / json"); Response.setHeader ("Pagera", "No-Cash"); Response.setDateHeader ("End", 0); Response.setHeader ("cache-control", "no-cache"); Stringwright SW = new stringwriter (); (Int c = is.read (); c! = -1; c = is.read ()) {sw.write (c); Println (c); } PrintWriter out = response.getWriter (); outside. Print (sw.toString ()); Println (sw.toString ()); Out.flush (); }}}

The value of the reference page is now: C: \ JBOSS \ jboss-5.0.1.GA \ server \ default \ tmp \ 4p72206b-uo5r7k-g0vn9pof-1-g0vsh0o9- B7 \ Nationwide.war \ WEB-INF \ rates JSN

But this place does not have a JSN file? It seems that JBOSS is not keeping this file in App.war or it does not deploy ??? Can anyone please help me?

First of all, check national level. Judge to ensure rate If so, try: 

  string rootPath = getServletConfig (). GetServletContext (). GetRealPath ("/"); File file = new file (actual path + "web-ihenf / rate jsnttpt"); InputStream = new FileInputStream (file);

MySql variables and php -

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

url rewriting - How to implement the returnurl like SO in PHP? -

-
This URL should work even after the rewrite. Is this possible? Otherwise, I can only hardcoded everything If you are trying to create a login system with redirection You need to use the HTTP_REFERER header to find out where the user came from so that you can send it back there. The best way to do this is to use something like this in your login form: // - Login php & Lt; Input type = "password" name = "password" /> & Lt; Input type = "hidden" name = "returnrelale" value = "& lt ;? php echo $ redirectURL ;? & gt;" / & Gt; & Lt; / Form & gt; Please note that some ISP, browser or proxy will delete the referrer header, so you can not rely on each user to work fully. If you use a statement, to check whether the header exists or not, you can send those users back to the homepage or whatever. Edit If you are looking to use $ _SERVER ['REQUEST_URI'], if you are running Apache It sho...

Which Python client library should I use for CouchdB? -

-
I am starting to experiment with CouchDB because it looks like we have the right solution to certain problems That all the work will be on a new project, which does not have any legacy dependency, which the client library will suggest you use, and why? If we overlap any of the OS. Freeband is available only in the collection of its ports, but asks to use the library's project website. None of those people are Ubuntu, which is only with ships, since those two OSAs are not common in libraries, I am probably installing something from source (and hopefully if I have time, then Ubuntu and FreeBSD People pack the package). For those interests, I want to use CouchDB as a convenient intermediate storage space for data passed between different services - think of a message bus system, but less formalities with. For example, we have daemons that download and pars the web page, then send an interesting bit to other daemons for further processing. Many of them are ill-defined until the...
