Assignment submission through Eclipse not only simplifies the grading process for the professor, TA, and student, but it also lets you to check the history of submissions and allows you to submit a project from your dorm room or any lab computer at any hour of the day.
Submitting allows the programmer to digitally send in a programming assignment to be graded. In order to submit an assignment stored as a Project folder, find the button Ambient > Submit Project for Grading. After choosing that, you will be faced with a dialog asking which assignment you'd like to submit.
Navigate through the tree of available courses and assignments in the upper frame of the window and find which one fits your code submission. Next, navigate to your project files in the lower left frame of the window to find your project folder. Select which files you will submit to be graded. These files will be listed in the frame on the right side of the window. Once all files to be submitted have been chosen and are thus listed on the right side, click the Submit button.
You will be asked to enter your NetID and password before your files are submitted, and after a successful submission, you will always be able to check back on your submission history with the Submit History button.
