iReport with JFreeCharts requirements

[JMoralesGER]

Nice to meet you,

 

we have payed and installed the last Versions of Jasper Reports (1.2.5), JFreeCharts (1.0.1) and iReport (1.2.5). We are normal users, not developers, and we are very happy to find and use your Products for our purposes (to have dynamic Reports).

 

We know, we do not need to compile iReport to use it, but we tryed preventive to do it, having the following problem (please, see also the attached text-file):

[javac] bad class file: C:iReport-1.2.5libjpa.jar(javax/persistence/EntityManager.class)

[javac] class file has wrong version 49.0, should be 48.0

 

We are also interested to have, not only the 12 Charts already existent, but to use all Charts included with JFreeCharts. We have seen, there is a Feature Request submitted by Tim Cloonan (artf 1303 "Incorporation of Gantt Report", still open) which would help us a lot.

 

Please, let us know a little more about both Subjects.

 

Many thanks, Jorge

Hi Jorge,

 

you can use iReport with java 1.4, but you need java 1.5 to compile it (the problem you refer to is a JVM compatibility issue with the EJB 3.0 classes).

 

iReport provides visual suppor for all the charts supported by JasperReports. You can still use charts not directly supported by JasperReports, but you need to write your own code in order to display the custom chart (you have to write a class that i.e. return the chart as Image).

 

The support for new charts is scheduled, but it is not on top of our to do list.

We hoppe, somebody integrates all JFreeCharts (we need mainly the gantts) into iReport, as soon as possible!
