Initial use of myeclipse 6.0

I started learning Java today.
With the help of Mr. Hu, two installation files were downloaded. Bytes
It is said that these are Java development environments.
Then the familiar VSS is used to remove the project on the server and configure it on myeclipse.
Create a new folder in package Explorer that is the same as the local project directory. myeclipse automatically determines that it is the virtual directory of the local project. Intelligent.
Then there is a sub-directory, and then there is a long wait...
It is said that myeclipse is automatically generating a solution. And it cannot be stopped. This is something I don't understand. It's a waste of time!
After the solution is generated, click the servers button in the lower right corner. Run server. It is said that this is equivalent to configuring IIS.
An error is generated, the latest version is obtained, the error is returned, and the error is returned. At last, I was able to perform my exercises with my eyes closed.
