Can I use it on jre1.2.2?

[tainy]

We have to use jdk1.2.2 and jre1.2.2 in our project for some reason,can I use newest version of JFreeChart ?
btw,what is the difference between the common document($30) and site licence document($150)?
thanks,can I get your contact phone and email?

Well, the javax.swing packages are a part of jdk1.2.2, which is encouraging.

As for the build, you could try and compile the examples with 1.2.2 and see how that turns out.

The jre is another problem. The standard microsoft vm only supports java 1.1.4 (-a perfectly good reason to hate MS) so you definitely need a plug-in. I have played around with this some, and don't think that jre1.2.2 will do. I am by no means sure though, if anybody knows differently, please correct me.

The jre 1.2.2 plugin is available at:

Too bad, really. I really liked JFreeChart, but had to abondon use of it because of the above mentioned plug-in problems.

hope this helps,
Søren

I haven't tried 1.2.2 for a while. If it doesn't work, I can't imagine there would be a lot of work to remove 1.3 specific code. If someone tries compiling against 1.2.2 and sends me the error log I'll be happy to help out...

It's the same document. Strictly speaking, the $30 is for one copy only. I'm hoping that larger companies will support the JFreeChart project by purchasing a documentation site licence. Only a couple have so far...I'm looking at ways to add some incentive to buy the site licence.

You can have my e-mail (david.gilbert@object-refinery.com).

to jacobsen:
thanks for you attention,but I cannot get your meaning very clearly.
I am now using sun jdk1.2.2 and jre1.2.2 but not microsoft jvm.
I ran the example on my pc(win2000) and found nothing wrong in compile it,but I am not sure about the usage of the whole jfreechart.

to david:

Thank you very much.JFreeChart is much more powerful than what we need.And I am now trying to learn to use it for our project.I mainly use it for the view of performance of the equipment.
I just compiled the demo files and run it on jre1.2.2 and I found no error.
But I am still not sure about it.For I dont know whether you have used some new feature after 1.2.2.Can you give me some advice?Or I only use jfreechart0.5.6?
About the document,I am persuading our manager to buy one.

[David Gilbert]

I develop using JDK1.3 at the moment, and don't really pay much attention to whether or not the classes I use are from 1.3 or earlier. That's lazy of me, but it's what happens...

If I want to buy your document and dont have the card you need,what should I do?I am in China.
Can you show me the catalog of the document?

Hi Tainy,

Sorry if I was unclear - what I wrote was more or less nonsense. Of course you should be able to run with jre 12.2. if the project compiles with 1.2.2

I was just trying to say, (a bit unrelated), that a standard Internet explorer without plug-ins only supports Java 1.1.4, which was news to me. And as my company requires that the web pages can be shown without additional downloads, jfreechart is more less out of the picture when developing applets.

Søren
