Hyperink in JRHtmlExporter

[avinash.moram]

Hi All,

 

I'm using JRHtmlExporter to display my report pages on browser. Now, in case if generated reports are having hyperlinks, how can i implement them here.

 

 

here is my code..

 

if(lFile.equalsIgnoreCase(pReportName)){

Resource lResource = getApplicationContext().getResource(lFile);

InputStream lInputStrm = lResource.getInputStream();

jasperPrint = JasperFillManager.fillReport(lInputStrm, pMap, lCon);

 

 

this is how i fill my report and return the jasperPrint object to the JRHtmlExporter and generate the report as following..

 

JRHtmlExporter lHtmlViewer = new JRHtmlExporter();

 

lHtmlViewer.setParameters(lMap);

lHtmlViewer.setParameter(JRHtmlExporterParameter.JASPER_PRINT, lResponse.getJasperPrint());

lHtmlViewer.setParameter(JRHtmlExporterParameter.OUTPUT_WRITER, response.getWriter());

lHtmlViewer.setParameter(JRHtmlExporterParameter.IS_USING_IMAGES_TO_ALIGN, false);

lHtmlViewer.setParameter(JRHtmlExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS, true);

lHtmlViewer.exportReport();

 

...And i found an interface in net.sf.jasperreports.engine.JRPrintHyperlink

 

I don't know how useful or how to use this,

 

can somebody help out of this pit.. it would be greatful.

 

 

Thanks,

Avinash.

Hey All,

 

I have come with an implementation like the following code, As i have to use the methods in JRAbstractExporter and JRPrintHyperlink, i have implemented them in a class and calling that class for generating the report.

 

The code is as follows:

Code:

import java.util.Map;

import net.sf.jasperreports.engine.JRException;
import net.sf.jasperreports.engine.JRPrintHyperlink;
import net.sf.jasperreports.engine.JRPrintHyperlinkParameter;
import net.sf.jasperreports.engine.JRPrintHyperlinkParameters;
import net.sf.jasperreports.engine.JasperPrint;
import net.sf.jasperreports.engine.base.JRBasePrintHyperlink;
import net.sf.jasperreports.engine.export.JRHtmlExporter;
import net.sf.jasperreports.engine.export.JRHtmlExporterParameter;


public class JRHtmlExporterClass extends JRHtmlExporter  {
	
	public void export(Map<String, Object> pMap,String pPath, JasperPrint pJP)
	{
		String linkType = "ReportExecution";
		String hyperlinkReference = "classpath:reports/customer-service-reports/catalogItemReports/catalogItem_by_gameId.jasper";			
		//Creating the Parameters, these are the parameters which i set in parameters tab of hyperlink option in jasper reports
		JRPrintHyperlinkParameter lPrintHyperlinkParameter1 = new JRPrintHyperlinkParameter("pGameId",new java.lang.String(),"$F{game_gameId}"«»);
			//JRPrintHyperlinkParameter lPrintHyperlinkParameter2 = new JRPrintHyperlinkParameter("_report",new java.lang.String(),"classpath:/reports/customer-service-reports/catalogItemReports/catalogItem_by_gameId.jasper"«»);
			System.out.println("Creating the Parameters=========="«»);
			//	Adding Parameters 
			JRPrintHyperlinkParameters lHyperlinkParameters = new JRPrintHyperlinkParameters();
			lHyperlinkParameters.addParameter(lPrintHyperlinkParameter1);
			//lHyperlinkParameters.addParameter(lPrintHyperlinkParameter2);
			System.out.println("Adding Parameters========"«»);
			
			//	setting parameters, hyperlink type and hyperlink target 
			JRPrintHyperlink lHyperlink = new JRBasePrintHyperlink();
			lHyperlink.setHyperlinkParameters(lHyperlinkParameters);
			lHyperlink.setLinkType(linkType);
			//lHyperlink.	setHyperlinkReference(hyperlinkReference);	
			
			System.out.println("setting parameters, hyperlink type and hyperlink starting"«»);
			this.startHyperlink(lHyperlink);	
			System.out.println("Starting Hyperlink"«»);
			this.setHyperlinkProducerFactory();			
			System.out.println("Setting the hyperlink producer factory"«»);
			
			this.setParameters(pMap);
			this.setParameter(JRHtmlExporterParameter.JASPER_PRINT, pMap.get("JASPER_PRINT"«»));
			this.setHyperlinkProducerFactory();
			this.setParameter(JRHtmlExporterParameter.OUTPUT_WRITER, pMap.get("OUTPUT_WRITER"«»));
			this.setParameter(JRHtmlExporterParameter.IS_USING_IMAGES_TO_ALIGN, pMap.get("IS_USING_IMAGES_TO_ALIGN"«»));
			this.setParameter(JRHtmlExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS, pMap.get("IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS"«»));
			this.exportReport();
			System.out.println("after export report"«»);
		
	}

 

 

I don't why its not displaying any link in my generated report.

 

I am using a custom link type called "ReportExecution", i set that through setLinkType, but everything in vain..

 

I am in xtream need of this drill down..

 

So can anybody pull me out of this stuff would be grateful..

 

 

Thanks in Adv,

Avinash.
