update little java program

My budget is U$ 100 . At the end you will have to deliver the updated [login to view URL] file and the source code updated in bit bucket. Today I have a java jar named [login to view URL] that opens a jasper report. I call this java class from my windows exe with a command line like this ( Im runing with jre1.8.0_144 ) : [login to view URL] [login to view URL] report_file_name dbpassword > [login to view URL] the 2 arguments, report_file_name and dbpassword are used to open a connection to the database and open the jasperviewer. This is working perfect. The problem is that every time I run this command line, I guess a new JVM is open, that cause and overhead to open the report. instead of that, my idea is to create a tcp/ip server + client solution, where the server is the java program you will develop and the client is my exe. I will first open the server with the parameter portnumber and also include > [login to view URL] so all outputs will be store in the log file. below are the functions I need to be implemented in the server: - the java server has to be always runing, can not be closed after the report is closed. - the java server will be started with a parameter that is the tcp/ip port number that will be set to be listen - the java server has to run only one instace of itself on the current windows user. In the case we are running in a rdp enviroment each user could have a different tcp port to connect ( Im not sure if this is necessary, any way the definition of the port number is not in the scope of this project, you will just read the parameter and list to that port ) - the java server need to listen to this port and answer the following 2 commands : 1 ) are_ you_alive , returns "yes". I will send first this command to know if the java server is running, in the case is not running I will just open it. 2) open report_file_name dbpassword Use this 2 parameters the same way are used today to open the jasper report - even when a report is already opened, the server has to able to open more reports without closing the already opened reports. - has to run on 32 and 64 bits - dont need a user interface I will upload the current source code to bit bucket so you will need an account to pull and push it. below is the current main function source code : package abrirrelatorio; /** * * @author Marcos */ public class Main { /** * @param args the command line arguments */ public static void main(String[] args) { try { long t0 = [login to view URL](); String strRelatorio = args[0]; // String strSenha = args[1] ; // // String strCaminhoJasper ; //folder of the report String XMLPath ; //xml file with parameters used in the report //log [login to view URL]("Relatorio: " + strRelatorio); //lib folder SubDiretorio subdir = new SubDiretorio(); strCaminhoJasper = [login to view URL]() + "\\relatorios\\" + strRelatorio; //log [login to view URL]("Caminho relatorio: " + strCaminhoJasper); XMLPath = strCaminhoJasper + ".xml"; //new reports VisualizaRelatorio visualizarRel = new VisualizaRelatorio( strSenha); //change xml into map to be used in the report XML2MAP parameterMap = new XML2MAP(); //open report [login to view URL](strCaminhoJasper, [login to view URL](XMLPath)); [login to view URL]( "Tempo de processamento (s) : " + ( [login to view URL]() - t0 ) ); } catch ( Exception e ) { @SuppressWarnings("unused") WarningDialog wd2 = new WarningDialog("Main :" + [login to view URL]()); [login to view URL] ( "Main :" + [login to view URL]()); } } }
