Re: [jCharts-users] Dependency on JDK 1.4

[Vikram R. <vr...@st...>]

yes, I am aware of the encoders dependency on 1.4 which is fine really.

Do you have a concrete plan to make the source 1.3 compatible. Some
timelines would be helpful. In the meanwhile, can I just go ahead and make
changes in the source and use it for my purpose? Are there any do's and
dont's there? I can mail the changes to the developers list if required.

Also, I think it would be a nice idea to create two separate build targets -
one for JDK 1.3 and one for JDK 1.4.

If resources are a problem, let me know how I can help out the project team
on this one. I like jCharts and I would like to contribute my two cents to
it.

thanks,
Vikram
