JasperReport is a reporting engine. It does not have those. Are you refereeing to JasperServer?

You should not have any problems editing older templates with a newer version of iReports.

It looks like one of my topics of conversation has been taken off the table. See you guys there Scott Vancouver, BC

If there’s a more appropriate place to post this please let me know. Will you be there? I'll will. I would be interested in meeting up will fellow forum members to network and talk about what they are doing with Jasper. I’m especially interested in talking about dashboards , charts, and how in restore my forum karma. I'll be getting into San Francisco Saturday afternoon.

Well that's a different story. The latest version as of this date is 3.7. http://jasperforge.org/website/jasperserverwebsite/JSJA%20Website/js_download.html?header=project&target=jasperserver There will be a 4.0.0 CE edition. Try contacting Jaspersoft. They should be able to tell you went the CE version is going to be released.

The reviews on Amazon are correct. The guides are good as a reference but they are not a learning tool. I have a copies of the ebooks which I look at once in awhile. If you what to learn more try some the links in the sticky in this forum If you want to get the ebooks there are update versions (2010) available on Jaspersofts website Most of what I know I've gained from developing reports and reading post in the forum.

Ok something is fishy. Mine was fine a few days ago and now it's changed to -666. I also noticed that yours in back to -666.

My karma just went to -666. It was ok yesterday. Did someone hack the forums or is it a bug? Who maintains the forums?

Yes it is possible to control the color of a bar based on a condition. It can not be done with the values you have access to through iReports. You need to create a chart customizer. See this post http://jasperforge.org/plugins/espforum/view.php?group_id=102&forumid=103&topicid=79120

It must be a glitch. I cannot believe someone would go to that much trouble. Anyway I gave you a few positives.

Welcome to chart heck /tools/fckeditor/editor/images/smiley/msn/teeth_smile.gif Jasper only exposes a small part of the JFreechart API. To access any properties outside of these you can write a chart customizer class. This may not do exactly want you want but it will be enough to get you started. This assume that you have some Java programming skills. public class <Your Class> extends JRAbstractChartCustomizer { public void customize(JFreeChart chart, JRChart jasperChart) { //Chart is a bar chart if(jasperChart.getChartType() == JRChart.CHART_TYPE_BAR) { BarRenderer renderer = (BarRenderer) chart.getCategoryPlot().getRenderer(); //Remove shadow effect from bar renderer.setShadowVisible(false); //Set maximum bar width renderer.setMaximumBarWidth(0.10); //Create no data message CategoryPlot categoryplot = (CategoryPlot) chart.getCategoryPlot(); categoryplot.setNoDataMessage("No data available"); categoryplot.setNoDataMessageFont(new Font("SansSerif",Font.BOLD,14)); categoryplot.setNoDataMessagePaint(Color.WHITE); //Set background as transparent categoryplot.setBackgroundPaint(null); //Set left margin before first bar and right margin after last bar categoryAxis .setLowerMargin(0.02f); categoryAxis .setUpperMargin(0.02f); } }}

Jaspersoft does offer a few courses for developers http://www.jaspersoft.com/training-services They are aimed towards someone that is starting out. At this time most training is on the job training. Also check out the sticky at the top of this forum. It contains links to other Jasper resources you might find helpful.

Try asking in this forum http://jasperforge.org/plugins/espforum/browse.php?group_id=99&forumid=108

Your best bet would be to download JasperServer and run your own test.

Did you recompile the reports with the newer version of iReports? I ran into this issue when we upgraded from 1.3.3 to 3.7.4.

Why not call the charting package directly if you are not going to use the reporting part? If you're interested in the charts that the CE edition uses then you should look at creating the charts directly with JFreeCharts.

The iReport guide can be purchased from Jaspersoft. If you are looking for help try this link http://jasperforge.org/plugins/espforum/view.php?group_id=102&forumid=103&topicid=56241

You may need to upgrade your version of Jasper not your Tomcat version. Check which version of Jasper you are using in Tomcat? The jar is jasperreports-#.#.#.jar

A few things. First determine what version you are using in your Tomcat. In my experince there is a limit to how backward compatible Jasper is. Next I would look at upgrading the version of Jasper in you install so it compatible with the version of iReport you are using.

Just a heads up on using iReport to decompile jasper files. There is a limit to how far back it will go. I was able to open 3..0.0 files with vesrion 3.7.0 iReports. However I was not able to open 1.3.3 files. That being said I would give it a try.

You will either have to write your own GUI that calls the Report or you can look at Jaspers Jasper Server product.

The closes the version are together the more likely the formats will be compatible. We went from 1.3.3 to 3.7.4. WE had to recompile all the reports because even the most basis report would not run without errors.
