JasperReport Tool

2005-06-14 00:09

Hello!

 

I have developed a wrapper class around the various functionalities of JasperReport.

 

Kindly give me a feedback / suggestion so that I can make is more perfact.

 

Reg,

Chetan

 

Code:

 
import java.sql.Connection; 
import java.util.HashMap; 
import java.io.File; 
import net.sf.jasperreports.engine.JasperExportManager; 
import net.sf.jasperreports.engine.export.JRCsvExporter; 
import net.sf.jasperreports.view.save.JRCsvSaveContributor; 
import net.sf.jasperreports.engine.JasperFillManager; 
import net.sf.jasperreports.engine.JRException; 
import net.sf.jasperreports.view.save.JRMultipleSheetsXlsSaveContributor; 
import net.sf.jasperreports.view.save.JRSingleSheetXlsSaveContributor; 
 
public class ReportManager { 
 
private String jasperFile; 
private String outputFile; 
private Connection con; 
private HashMap parameters; 
 
public ReportManager() { 
} 
 
public void setConnection(Connection con) { 
this.con = con; 
} 
 
public void setParameter(HashMap parameters) { 
this.parameters = parameters; 
} 
 
public void setJasperFile(String jasperFile) { 
this.jasperFile = jasperFile; 
} 
 
public void setOutputFile(String outputFile) { 
this.outputFile = outputFile; 
} 
 
public void saveAsHTML() 
throws JRException { 
JasperExportManager.exportReportToHtmlFile(jasperFile, outputFile); 
} 
 
public void saveAsPDF() 
throws JRException { 
JasperExportManager.exportReportToPdfFile(jasperFile, outputFile); 
} 
 
public void saveAsXML(boolean withImage) 
throws JRException { 
JasperExportManager.exportReportToXmlFile(jasperFile, outputFile, withImage); 
} 
 
public void saveAsXLS(boolean isMultipleSheet) 
throws JRException { 
 
if(isMultipleSheet) { 
new JRMultipleSheetsXlsSaveContributor().save( 
JasperFillManager.fillReport(jasperFile, parameters, con), 
new File(outputFile)); 
} else { 
new JRSingleSheetXlsSaveContributor().save( 
JasperFillManager.fillReport(jasperFile, parameters, con), 
new File(outputFile)); 
} 
} 
 
public void saveAsCsv() 
throws JRException { 
new JRCsvSaveContributor().save(JasperFillManager.fillReport(jasperFile, parameters, con), 
new File(outputFile)); 
} 
 
public byte[] getPDF() 
throws JRException{ 
return JasperExportManager.exportReportToPdf( 
JasperFillManager.fillReport(jasperFile, parameters, con)); 
} 
}

Hmmm ... what for should it be??? As this isn't within the JasperSource I wouldn't use such a "additional" wrapper class just to have the "common/most used" functions in one class.... when Teodor changes something the wrapper class also must be changed... so I'd prefer using the provided Jasper classes instead. I guess Teodor has built the Jasper[function]Manager classes for easy method access, or Is it to complex for you, to use these given methods?

I have shared the same concerns as you in the beginning.

 

But we are going to use it in an application that will have average 30 concurrent uses. Hence we need to do pooling with the Reporting Tool, hence I developed a common class that we can pool.
