URI for JFreeChart and JCommon JARs

mspreitz · Post by **mspreitz** » Thu May 01, 2008 9:31 pm

I maintain and distribute a Java application that uses JFreeChart (and thus JCommon). I do NOT distribute JFreeChart and JCommon (I work in an organization that has significant administrative overhead for such things). My application uses Java's built-in URLClassLoader to load the JFreeChart and JCommon JARs directly from Object Refinery. This used to work --- the JARs used to be available at http colon slashslash www dot object-refinery dot com slash jars slash jxxx-version.jar. Now I can no longer find the JARs at Object Refinery (nor SourceForge). I can find the ZIPs containing the JARs, but those are not equivalent for class-loading purposes. Have the JARs simply been moved elsewhere, or are they really no longer published? If the latter, can they be restored?

Thanks,
Mike

I don' thave the answer to that particular question, but as a programmer myself, I'm wondering that it's a little risky depending on a) the user to have an active Internet connection whenever the application is loaded, b) the files to be available (which they're not, as you've now found) on the server and for the server to be available, and c) download speed of those files to be reasonable enough to enable a short download time before the application can be used.

Perhaps now is the time to tackle that 'significant administrative overhead' head-on, because even if you find a new location, it's most likely not going to be permanent.

Yes, I was nervous about all those things when I first made my application load JFreeChart that way. That was six years ago, and for six years none of those issues was actually a problem!

Do you have the URI(s) you were using? I did some maintenance on the server a few days ago, and maybe I moved or deleted a file I shouldn't have.

Yes, the URL is in the original message --- with punctuation spelled out because this forum system will not allow me to include something it recognizes as a URL in a post. I will repeat here, with the actual versions I am using:

http colon slash slash www dot object-refinery dot com slash jars slash jxxx-version.jar

where jxxx-version is one of

jcommon-0.6.4
jfreechart-0.9.2

Thanks!

I put those versions back online, let me know if you have any trouble.

It's working great.

Thanks!
