Re: [Geotools-gt2-users] gt2 legend, mouse event and map units questions

[Steffen G. <ste...@in...>]

Hello,

I just downloaded all required sources for the Legend and build up the 
package structure in my project. Implementing it to my own application 
(with Legend test = new Legend(map,"test");    - whre map is my 
mapcontext) leads to the following error. What is going wrong? Does 
anybody knows what the error is like?

Thanks,
Steffen.
