Sample EJB app with JasperReports?

2003-07-21 08:32

Hello!

 

I have to write reporting tool using Enterprise Java Beans and BEA WebLogic and Tomcat servers. Unfortunatelly I'm new to EJB technology. I'm reading a lot but it would be faster and easier for me if I could see source code of sample EJB application using JasperReports and database data. Can somebody help me, please?

Best regards

public JasperPrint viewReport(String module, Map params, String reportPath) throws Exception {

try {

cw = new ConnectionWrapper();

cw.begin();

try {

StringBuffer preCompPath = new StringBuffer();

if (reportPath != null && reportPath.length() > 0) {

preCompPath.append(reportPath);

preCompPath.append("/precompile/");

} else {

preCompPath.append(precompileDir);

}

preCompPath.append(ReportProp.getReportFileInput(module));

if (params == null && params.size() <= 0)

params = new HashMap();

 

return JasperFillManager.fillReport(preCompPath.toString(), params, cw.getConnectionObj());

 

} catch (Exception e) {

throw new EJBException(e);

}

} catch (EJBException ejbe) {

ejbe.getCausedByException().printStackTrace();

throw ejbe;

} finally {

try {

if (cw != null) cw.close();

} catch (Exception e) {

e.printStackTrace();

}

}

}

Hi,

 

I do not have a sample that uses EJB to fill a report

but I guess in this scenario people will get to use

the JRBeanCollectionDataSource to wrap collections

of beans.

 

I hope this helps.
