Hi,

Download the entire project from sourceforge.net

and you'll find samples inside that will help

you create you own reports.

Good luck!

I am a newbie to this site. I started with the report generation examples under demo/samples. The first prog. I used was ChartApp. It runs for run option only with the existing files, other options throw an exception. I have a couple of questions.

- What is the sequence of options/arguments I should use for the program.

- What kind of file is the file used as filename. Is it already created by the user in some particular format.

- What kind of files are '.jasper', '.jrprint', '.jrpxml' and for what purpose they are used.

- Can I use the report generator from a jsp file on say click of a button (I think yes, just supply the task option and file name to the program).

Any help is appreciated.

Thanks

Hi,

Another set of question :

- how can we connect the report generator to a oracle or any other database with say a jdbc conenctivity and then that query will generate the report.

- how to include graphs in the report. These graphs may be generated by a graphical tool say the one you are using with jasperreport(jfreechart).

Thanks in advance for the help.

Hi,

JasperReports is a library. It is not a standalone

application. It only offers reporting functionality to

other Java applications.

The samples provided are simple Java applications

that show how to use the JasperReports library.

There is a sample application for every main feature

of the library including charts, subreports and even

a Web application using JSP.

What error have you encountered when running the

samples? Have you checked the "how.to.txt" files provided in the project tree?

I suggest you read the source code of those

sample applications and you'll learn to use the

library.

The .jasper file is the compiled report design

(serialized object).

The .jrprint file is the generated report (serialized

object).

The .jrpxml file is the generated report in XML

format.

I know the documentation is scarce, but it should

be read at least once.

Thank you,

Teodor

One more question if I use the build.xml to compile and run the sample programs they work fine but if I use Command line

java ChartApp -Tcompile -FChartReport.xml

It throws an exception

org.xml.sax.SAXException: System property org.xml.sax.driver not specified

where to specify this systemProperty when using from commandline or compile the report using xml file from a jsp page.

Thanks

Thanks. I am facing one more problem. I loaded the latest xerces.jar which I was using for my application and then started to compile xml file to '.jasper' file, but got the following exception. The xerces loaded at your site gives problems with initializing the servlets.
