The following is a list of small demo programs in the geotools svn , in the gt/demo directory. Some demos use data in the sample-data module in gt/module/sample-data and some require the latest unreleased geotools code in svn (referred to below as trunk).

These demos were not included in the 2.0rc1 release, but some are attachment files on this wiki.

Where to find the geoTools SVN ?

I cannot find it...can you post it out here?

I am a geoTools newbie

I am trying to find some tutorials that teach us how to use geoTools steps by steps...

And i don't think the tutorial provide by the original one is suitable for me .

Can me create a newbie page here ?

thanks

Ok, thanks Rueben Schulz, i found the link.

But would it be a good suggestion to create a new page for newbie?

I think we really need some VERY VERY BASIC tutorials more then some UML illustration tutorials....

Unfortunately, geotools developers do not have much time to write tutorials. We still have many areas of the code base without tutorial, besides missing tutorials for beginers.

My only suggestion is to make comments (give us feedback) about areas where the tutorials are confusing or missing. But, the wiki is open to everyone to modify, so you can start a newbie page if you have time. See [How to get started using Geotools2] for more information.

Hi I have a question for Marcelo. I am getting the same compile problem that you posted about when I try and run geoserver. Did you get the problem resolved and can you point me in the right direction.

Thanks,

Matt.
