javydreamercsw Posted April 24, 2007 Share Posted April 24, 2007 I'm entering the jasper reports from Java tour today and while attemptiing to create my first custom datasource I encountered the following output generated from within the jasper reports classes I'm implementing I suppose: Code:driver=com.ibm.db2.jcc.DB2Driver@17ace8dattributes=[Ljava.sql.DriverPropertyInfo;@b0f13dResolving properties for: com.ibm.db2.jcc.DB2Driveruser (Required: true) No choices. Description: The user name for the connectionpassword (Required: false) No choices. Description: The user's password for the connection Ok, I get I'm somehow missing the username and password but they are provided in the code below: Code:[code]/* * DreamerDataSource.java * * Created on April 23, 2007, 3:52 PM * * To change this template, choose Tools | Template Manager * and open the template in the editor. */package iReport.Objects;import SQLConnection.DBConnection;import java.sql.Connection;import java.sql.ResultSet;import java.sql.SQLException;import java.util.HashMap;import net.sf.jasperreports.engine.JRDataSource;import net.sf.jasperreports.engine.JRException;import net.sf.jasperreports.engine.JRField;/** * * @author javydreamercsw */public class DreamerDataSource implements JRDataSource{ private ResultSet rs=null; /** Creates a new instance of DreamerDataSource */ public DreamerDataSource(Connection con,String sql) throws SQLException { setResultSet(con.createStatement().executeQuery(sql)); } /** Creates a new instance of DreamerDataSource */ public DreamerDataSource(ResultSet rs){ this.setResultSet(rs); } /** Creates a new instance of DreamerDataSource */ public DreamerDataSource(){ } public boolean next() throws JRException { try { return getResultSet().next(); } catch (SQLException ex) { throw new JRException(ex); } } public Object getFieldValue(JRField jRField) throws JRException { try { return getResultSet().getObject(jRField.getName()); } catch (SQLException ex) { throw new JRException(ex); } } public ResultSet getResultSet() { return rs; } public HashMap createHashMapFromResultSet(ResultSet rs, int name,int value){ HashMap hm = new HashMap(); try { while(rs.next()){ hm.put(rs.getString(name),rs.getObject(value)); } } catch (SQLException ex) { ex.printStackTrace(); } return hm; } public static void main(String[] args) { DreamerDataSource dds= new DreamerDataSource(); dds.createDatasource(); } public void setResultSet(ResultSet rs) { this.rs = rs; } public JRDataSource createDatasource(){ DBConnection db = new DBConnection("jdbc:db2://10.60.48.110:50000/PW_DATA","user","password",4); String sql = "select distinct a.material_id,1 from BAX_CONSUMPTION_ST a inner join (select distinct order_id, product_id from BAX_BATCH2_VW " + "where upper(product_id) like '%') as b on b.order_id=a.batch_id"; DreamerDataSource dds=null; try { dds=new DreamerDataSource(db.getConnection(),sql); } catch (SQLException ex) { System.err.println("Error"«»); ex.printStackTrace(); } return dds; }} Where's the error?
