Why Temporary Tables? To eliminate bad data When aggregations or computations are required To do snapshots in time To simplify processing To “divide and conquer”

Code structure XML representation Tokens and Parameters Invoking report window RunReport Backend functions Jasper/Ireport

XML Representation

Tokens and Parameters For substitution into queries –$ For display –XML elements for branching in code –XML elements –XML attributes

Tokens and Parameters

Invoking Report Window Via menu –Report window launched via menu.php –$url = "runReport.php?rtype=". $cat. "&reportNumber=". $report["reportNumber”]… Via parameters page –Want tokens, but not parameters –$url = “kickPoint.php?rtype=…” Using full parameter functionality –$url = "kickPoint.php?rtype=". $cat. "&reportNumber=". $report["reportNumber"]. "&lang=". $lang. "&site=". $site. "&patientStatus=". $report["patientStatus"]. "&treatmentStatus=". $report["treatmentStatus"]. "&testType=". $report["testType"]. "&groupLevel=". $report["groupLevel"]. "&otherLevel=". $report["otherLevel"]. "&menu=". $report["menuSelection"];

runReport.php DEBUG_FLAG = true displays much of the processing and queries 1.Reads parameters 2.Special processing (Nastad, PEPFAR) 3.Generates temp tables 4.Generates graph 5.Formats and displays report in separate window 6.Optionally generates Excel or PDF (Jasper)

Agenda Introduction Using Jasperreports Q&A

Introduction An Open source Java reporting tool

Using Jasperreports Design a report Integrate with TOMCAT Fill the report with data Export the report

Design a report Using iReports (layout, parameters for input, fields for output)

Design a report Generate a JRXML file. patientRpt.jrxml <jasperReport name="patientRpt" …. … …

Design a report You can edit the JRXML files directly.

Integrate with TOMCAT reports.xml Add/Edit entries in reports.xml so we can get the right request of TOMCAT. For example, Active/Inactive Patients Patients actifs/inactifs … patientRpt.jasper

Integrate with TOMCAT ReportViewerServlet serves to generate reports

Integrate with TOMCAT Get the parameter values from the POST/GET method. ReportViewerServlet.java public void doPost(HttpServletRequest req, HttpServletResponse resp) { … String lang = req.getParameter(PARAM_REPORT_LANG); String site = req.getParameter(PARAM_REPORT_SITE); …

Fill a report with data Get the database connection. For example, Connection conn = DBUtils.getConnection(JNDI_DATA_SOURCE_NAME);

Fill a report with data Put values to parameters as we mentioned in the previous phases. For example, parameters.put(“ siteName ”,”Hopital Grace Children”); Especially queries.

Fill a report with data Using the connection and queries, we can get the data to fill the report. JasperPrint jasperPrint = JasperFillManager.fillReport(report, parameters, conn);

Export a report Jasperreport offers several formats. CSV (JRCsvExporter) PDF (JRPdfExporter) XLS (JRXlsExporter) XML (JRXmlExporter) HTML (JRHtmlExporter)

Export a report Create an exporter, for example: JRHtmlExporter exporter = new JRHtmlExporter(); Set parameters for the exporter exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint); exporter.setParameter(JRExporterParameter.OUTPUT_WRITER, response.getWriter()); Export the report exporter.exportReport();

Export a report
