Hello.

What kind of installer did you installed (zip, windows, linux, with jre or without)?
Did this error appeared at first run or after some usage?

Is something more written in D:\Program Files\NextReports 2.2\log\nextreports.log, derby.log or error.log? Please send us these three files on next_support@asf.ro

Hello,

I installed .zip on Windows XP with JRE. This is occuring from the first run. Sent you the zip file separately on above address.

Thanks!
Jason

Hello.

I hope this is your problem. Please confirm.

If you have NextReports application open with derby Demo data source connected you cannot create another connection to that embedded database. Please disconnect from NextReports datasource and then run the example.

Thanks Mihai! It was the problem.

In the near future we will have an integration page on the nextreports site.

For now we can offer a zip archive with the needed libs, java doc and some simple demo examples. See readme.txt from the zip for more information.

Thank you for the examples. Just to be clear, you don't actually rely on the Next Reports installation in production? I.e. I would have Next Reports installed on my local box to develop the reports, but when we deploy the application (with the report files) to production, I no longer need the full installation (just the JAR files).

Looking at DemoUtil.java, it appears that NEXTREPORTS_HOME is only used to locate the demo report and Derby database.

Thanks,
Josh

Yes, you do not need the NextReports application installed. NextReports just helps you to create the reports. Then you can run the reports inside your application.
And yes, NEXTREPORTS_HOME is used just for example (to run the demo examples).

What you need from the jar files is shown below :

* jcalendar-1.3.2.jar is not needed (it is used for the swing demo).
* derby-10.2.1.6.jar is not nedded (it is used just to connect to demo derby database)

* nextreports-engine-2.1.jar is needed for all type of exports
* xstream-1.3.1.jar is needed for all type of exports
* commons-logging-1.1.jar is needed for all type of exports

* itext-2.1.5.jar is needed just for PDF and RTF exports
* itext-rtf-2.1.5.jar is needed just for RTF export

* poi-3.0.jar is needed just for EXCEL export
* commons-lang-2.4.jar is needed just for EXCEL export
* commons-beanutils-1.8.0.jar is needed just for EXCEL export
