Course Description:         

This course focuses on server-side web applications programming and the fundamental architecture, system, and components of web applications that are instrumental to the success of many e-commerce websites and enterprise networks. Students will learn key technologies and frameworks in the development of web applications using a programming language such as Java.

Course Objective:

Course Policies:

Attendance Policy:

The university requires attendance in all classes, and it is also important to your learning. The attendance record may be provided to deans who request it. If your grade is just a little below the cutoff for a higher grade, your attendance will be one of the factors that we consider, in deciding whether to "bump" you up to the higher grade. Missing three or fewer lectures will be considered good attendance. In rare cases, such as medical needs or jury duty, absences may be excused with appropriate documentation. You should let me know in advance, when possible, and submit the documentation I seek. You should make up for any materials missed due to absences.

NOTE: recitation attendance is required. Both announced and unannounced quizzes will be given during recitations.

Missed exam Policy:

A missed exam will be recorded as a grade of zero. We will follow the university rules regarding missed final exams (see http://registrar.fsu.edu/dir%5Fclass/spring/exam_schedule.htm), for all the exams, including the final exam.

Late Assignment Policy:

In order to enable us to provide timely solutions to assignments, we have the following policy regarding submission of late assignments.

Incomplete Grade (Grade of 'I') Policy:

The grade of 'I' will be assigned only under the following exceptional circumstances:

ACADEMIC HONOR POLICY:
The Florida State University Academic Honor Policy outlines the University
's expectations for the integrity of students' academic work, the procedures for resolving alleged violations of those expectations, and the rights and responsibilities of students and faculty members throughout the process.  Students are responsible for reading the Academic Honor Policy and for living up to their pledge to . . . be honest and truthful and . . . [to] strive for personal and institutional integrity at Florida State University.  (Florida State University Academic Honor Policy, found at http://fda.fsu.edu/Academics/Academic-Honor-Policy.)

AMERICANS WITH DISABILITIES ACT (ADA):

Students with disabilities needing academic accommodation should:
(1) register with and provide documentation to the Student Disability Resource Center; and
(2) bring a letter to the instructor indicating the need for accommodation and what type.  This should be done during the first week of class.

This syllabus and other class materials are available in alternative format upon request.

Academic Integrity:

Remember that the goal of programming assignments and homework is to enhance your analysis, reasoning, and programming skills. Indulging in academic dishonesty defeats this purpose apart from being unfair to other students. In case you have any questions about whether an act of collaboration may be construed as academic dishonesty, please clarify the issue with the instructor before you collaborate.

All students should follow FSU Academic Honor Code. You might be assigned a grade of 'F', if you are found to have indulged in academic dishonesty.
