How to deploy Jasper reports in JBoss Server

2004-06-27 23:02

Iam using ireports 0.3.0 as gui tool for Jasper reports.

There is a problem deploying Jasper reports on JBOSS server.

There is also a file called px being created for each report created

 

Any information regarding the deployment would be highly appreciated.

Hi,

 

You just have to put all the needed *.jar files of JasperReport into the lib-dir of your JBoss-Dir (e.g. "C:JBossserverdefaultlib")

 

Then point to the Jasper-Jar within your SessionBeanSourceCode with the help of a system-variable (e.g. "System.setProperty("jasper.reports.compile.class.path", "C:\JBoss\server\default\lib\jasperreports-0.5.3.jar");")

 

So I got it to work with JBOSS.

Deploying Jasper Reports on JBoss

2004-06-29 23:29

 

Thank U for the response.

We have deployed Jasper Reports in JBOSS Server in the same way mentioned by U.

But when we export report to a HTML file How can we show in the browser.

when the report is being exported the exporting parameter is accepting only the actual path

of the html file

Is there way to mention the relative path of the html file

 

Iam sending here with the code that Iam using

 

// To load the .jasper file:

JasperReport template = JasperManager.loadReport("c://Ireports//reports//abc.jasper");

JasperPrint report = JasperManager.fillReport(template, parameters, conn);

//To show the reoprt, create a JRViewer and stick it in a dialog:

JasperExportManager.exportReportToHtmlFile(report, "c://Ireports//reports//abc.html");

You can do it the following way.

Get the OUT-Stream of the response object and write the report into this stream without first saving it as a file:

 

JasperPrint jasperPrint =

JasperFillManager.fillReport(

jasperReport,

parameters,

conn

);

 

JRHtmlExporter exporter = new JRHtmlExporter();

exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);

exporter.setParameter(JRExporterParameter.OUTPUT_WRITER, response.getWriter());

 

exporter.exportReport();

 

 

Regards,

Ralf

Then you have to extend your code by the following lines:

 

Map imagesMap = new HashMap(); request.getSession().setAttribute("IMAGES_MAP", imagesMap);

 

exporter.setParameter(JRHtmlExporterParameter.IMAGES_MAP, imagesMap); exporter.setParameter(JRHtmlExporterParameter.IMAGES_URI, "image.jsp?image=");

 

 

 

 

And you have to implement the jsp "image.jsp" as follows:

 

<%@ page import="java.util.*" %>

<%@ page import="java.io.*" %>

 

<%

Map imagesMap = (Map)session.getAttribute("IMAGES_MAP");

 

if (imagesMap != null)

{

String imageName = request.getParameter("image");

if (imageName != null)

{

byte[] imageData = (byte[])imagesMap.get(imageName);

 

response.setContentLength(imageData.length);

ServletOutputStream ouputStream = response.getOutputStream();

ouputStream.write(imageData, 0, imageData.length);

ouputStream.flush();

ouputStream.close();

}

}

%>

 

 

Hope it works for you.

Regards

Ralf
