opening project in eclipse
I am trying to start to use Eclipse.
I downloaded some java projects lafrom SourceForge.net because I want to learn. And I try to open those projects from Eclipse. So, I create a new project in Eclipse and import the downloaded zip source code into that project folder. But when I try to run the program, it said that "The selection cannot be launched and there are no recent launces.". I think the way I open the existing projects in Eclipse is wrong. Because it always happened everytime I tried to open those kinda files even though creating new project in eclipse and writing java code and running is ok.
So, how can I open and run the existing project from other sources in Eclipse.
Thanks in advance.
