CS644/IT632/CS397K: Internet Computing with Distributed
Components
Since some students don’t have the textbook yet, we are going to learn Web services first.
My tutorial on Web services will also give you a good introduction to the Web
architecture and HTTP protocol, which are important in this course. Instead of reading
the textbook, you are going to read my Web services tutorial “Essential Concepts of Web
Services” posted at http://csis.pace.edu/~lixin/pclc/ws/webServiceConcepts.pdf.
The due day for all the tasks specified here is September 24, 2005.
Tasks to be completed in Weeks 2 and 3 (9/11 – 9/24):
1. Read tutorial “Essential Concepts of Web Services” posted at
http://csis.pace.edu/~lixin/pclc/ws/webServiceConcepts.pdf. You can find all
download links for the Web service course material at
http://csis.pace.edu/~lixin/pclc/ws/”, but you only need to read those I specified
here.
2. Prepare for the following Web service lab session by conducting the following 3
steps:
a. Download file “endorsed.zip” at
http://csis.pace.edu/~lixin/pclc/ws/endorsed.zip, and unzip its contents (a
set of jar files) into both “C:\Sun\AppServer\jdk\lib\endorsed” and
“C:\Sun\AppServer\jdk\jre\lib\endorsed”. Here I assume that you followed
my instructions and used Java SDK at “C:\Sun\AppServer\jdk”. If you
have chosen to use a Java SDK installation at a different location, you
need to use your actual Java SDK installation directory to replace the
above “C:\Sun\AppServer\jdk”. Make sure that there is no subdirectory in
either of the two “endorsed” directories.
b. Download file “axis.zip” at http://csis.pace.edu/~lixin/pclc/ws/axis.zip,
and unzip its contents in a new directory “axis” at
“C:\Tomcat5.5\webapps\axis”.
c. Download file “webServiceLab.zip” at
http://csis.pace.edu/~lixin/pclc/ws/webServiceLab.zip, and unzip its
contents at “C:”.
3. Read the first 8 pages of the Web services lab manual at
http://csis.pace.edu/~lixin/pclc/ws/webServiceWorkshopLab.pdf, and follow the
instructions to complete the implementation of a Java Web service as well as a
Java client application for the Web service.
4. Assignment 1 (due on 9/24): Implement in Java and the AXIS toolkit a Web
service that receives an integer and returns an integer that is 1 plus the received
integer; write a Java client to consume this Web service. The assignment
submission will be the two Java source code files, one for the Web service

Assignment 1 (due on 9/24) : Implement in Java and the AXIS toolkit a Web service that receives an integer and returns an integer that is 1 plus the received integer; write a Java client to consume this Web service. The assignment submission will be the two Java source code files, one for the Web service

implementation, and one for its consumption. Zip these two files together and attach it to your reply to my assignment 1 thread in the forum for Weeks2and3.

  1. In course Discussion Board forum Weeks2and3 , reply to each of the following questions: a. What is the main objective of Web services? b. What is the minimal information that a client needs to consume a Web service?
