tanvirtonu Posted December 10, 2007 Share Posted December 10, 2007 I want to send the entire sql query from my java application into a compiled jasper report.For this,I tried with the following code-Code:class frmReport{ static HashMap <String,String> map=new HashMap<String,String>(); frmReport() { map.put("Sql","Select * from loan where loan_id=1"«»); runReport("amabrick","root","tanvir","./Report/MyReport.jasper"«»); } public static void runReport(String databaseName, String userName, String password,String reportFile) { try{Connection jdbcConnection = connectDB("amabrick","root", "tanvir"«»); JasperPrint jasperPrint = JasperFillManager.fillReport(reportFile, map, jdbcConnection); JasperViewer.viewReport(jasperPrint); }catch(Exception ex) { String connectMsg = "Could not create the report " + ex.getMessage() + " " + ex.getLocalizedMessage(); System.out.println(connectMsg); }}public static Connection connectDB(String databaseName, String userName, String pword) { Connection jdbcConnection = null; String serverName = "localhost:3306"; String mydatabase = databaseName; String url = "jdbc:mysql://" + serverName + "/" + mydatabase; // a JDBC url String username = userName; String password = pword; try{ Class.forName("com.mysql.jdbc.Driver"«»); jdbcConnection= DriverManager.getConnection(url, username, password); }catch(Exception ex) { String connectMsg = "Could not connect to the database: " + ex.getMessage() + " " + ex.getLocalizedMessage(); System.out.println(connectMsg); } return jdbcConnection; } I cant understand how to use a Map to send query to jasper report.And how should I configure iReport for this.I mean-do I need any paraameter or something else?

vinays84 Posted December 10, 2007 Share Posted December 10, 2007 Use a parameter for the query entitled "Sql" (It has has to match up to the name attribute in the map). For your report query, simply put $P!{Sql}. Link to comment Share on other sites More sharing options...
tanvirtonu Posted December 11, 2007 Author Share Posted December 11, 2007 Use a parameter for the query entitled "Sql" (It has has to match up to the name attribute in the map). For your report query, simply put $P!{Sql}.Where shud I put- $P!{Sql} . Which is the name attribute in Map.I made a parameter and i name it- Sql , type-String,then in report query I ONLY wrote- $P!{Sql}.My code was as it is now. But it didnt work. Cud u be a little clearer.Post edited by: tanvirtonu, at: 2007/12/10 18:30 Link to comment Share on other sites More sharing options...
