Orson Chart Beans

Post by **david.gilbert** » Wed Jul 04, 2007 5:19 pm

Someone at Sun convinced me to have a go at creating a set of chart beans based on JFreeChart, and the result of my initial experimentation is now available to download. Please see:

http://www.jfree.org/orson/

There's still more work to be done to make these "beans" genuinely useful, but I think "Orson 0.5.0" is a good starting point. Feedback is welcome.

This looks great! Thanks for all of your hard work.

I get error like "Cannot load component class XXX.class. You need to compile the files and set them on classpath".

Can you post the exact error, along with some details of the JavaBeans environment you are using (NetBeans or something else, version number etc)?

I am using Netbeans 5.5 on Windows XP Platform with JDK1.5

Its a dialog box popup. Where do i check for detailed exception. There is no button on the dialog to show exception.

Thanks for the details. I'll have a go at reproducing this.

Just a quick thought...

I don't usually work on Windows, but does Java handle the space in the directory path OK?

Just to reconfirm, i changed the directory of the library and here is the same exception again. No problems with other components i am using.

Code: Select all

Do you thinks its go to do with jdk version you have compiled i higher than i am using.

I had the same error and fixed it with a rebuild of orson.

It is posible to move the 'jLineChartBeanInfo' into a Form but i can't embed it in a JFrame or JPanel. So it is not fully loaded i guess.

When i open the properties all de values display 'object is not an instance of declaring class' of een 'java.lang.ClassCastException@<garbage>'.

Someone?

edit:
With some playing with the Post-Init code i've succeed to add a ChartPanel. But this solution works around the native GUI designer of course. Just set the Layout on null in the designer and add your own code to add the ChartPanel.

giorgio42 · Post by **giorgio42** » Wed Aug 29, 2007 10:30 pm

You have to add the JFreeChart libraries to your project's dependencies.

I have tested adding a JLineChart to a JFrame using NB 6.0 successfully.

Initially I got the error
"I get error like "Cannot load component class XXX.class. You need to compile the files and set them on classpath"."

Simply putting the JAR files on my classpath proved to be no avail. Rebuilding orson seemed to be the solution. Howto for netbeans 5.5:

Rebuilding Orson 0.5.0 in Netbeans 5.5
1) From menu: File - New Project - select: Java Project with existing Ant Script - (Next)
2) Location - Select the "orson-0.5.0" folder that contains the ant, etc folders.
3) Build Script - Select from the "orson-0.5.0\ant" folder the build.xml file
4) Continue the wizzard until the end. (Next^n). You don't need to set it as your main project however.
5) Right click on the Orson Project and select "Build Project".

Turn Orson in a Library
1) From Menu: Tools - Library Manager - Select: "New Library" (Orson)
2) Add the freshly build jar file from the Orson project folder. (Ok)
3) (Optional) Add the source and javadoc folder as well. (Ok)

Adding Orson to your beans pallete using a library
1) From menu: Tools - Pallete Manager - Swing/AWT Components.
2) Select "Add from Library" - select the Orson library - click ok - add it to a category (the beans if you don't want to mess up the other pallets).

Note: As giorgio42 points out make sure that you have to add the JFreeChart libraries to whatever project you want to use the beans with. This files are actually included with the Orson 0.5.0 download and can be found in the lib folder.

Everything should work like a charm now - this has been tested under Windows XP running JDK 1.5 using Netbeans 5.5. Should be the same procedure under Linux or Mac though.

Let me know if anyone has any problems.

giorgio42 · Post by **giorgio42** » Wed Sep 05, 2007 11:44 pm

Just for your info: I tried the Orson libraries with latest daily builds of NetBeans 6.0, but without success: first an NPE when I drop a JLineChart on a JFrame and then next one when I try to save the form (and I finally cannot save it).

jsnel · Post by **jsnel** » Thu Sep 06, 2007 12:10 am

That's odd since giorgio42 claims it worked with NB 6.0 (see above). Perhaps the both of you can specify exactly what steps you took and see where your methods differ.

astrakh · Post by **astrakh** » Mon Sep 10, 2007 8:43 pm

Orson have no such a bean. But it is not cool to use the charts without ChartPanel.
So is it an intentional solution or just a consequence of not completed state?

Thank you.
