• StudentRecords processes Student records stored in a simple textfile [student.dat]. StudentRecords adds new student records to the student.dat file in the format lastName:firstName:studentID:gpa. Clicking Display All Student Records opens student.dat; counts total records; creates an array array the appropriate size; populates the array with Student object instances; and then sorts results in alphabetical order (far right, below).
       
• ScreenSaver draws 100 randomly filled shapes (lines, triangles, spheres). Uses Java 2D with MyShape interface plus MyLine, MyTriangle, and MySphere.
• Complex is an abstract data type. The ComplexTest.java driver application instantiates two Complex objects and then performs calculations using the two objects.
• Morse Code generates Morse code from an input line of letters a-z and digits 0-9.

Server-side Java and XML

Web Services

• Addressbook Manager  Application to manage XML-based address book (AddressBook.xml) file. Includes user interface for adding, deleting, searching, and editing contacts. Implemented as JavaServer Pages (JSPs), deployed to Apache Tomcat. More...
• Compound-interest calculator  A Web service calculates compound interest payment amounts and total cost over the life of a loan. Deployed to Tomcat/AXIS with web-services deployment descriptor file. Generated WSDL after deployment. Simple console-based client obtains response from service as shown below.
  
• ContactReportSAX.java uses the SAX parser to parse AddressBook.xml, search for and display the specified contact.
• A simple Newspaper.xml file based on this XML Schema (newspaper.xsd). Newspaper.java finds headline by the author whose name is entered at the command line.
• ContactPrintout.java finds a contact in the AddressBook. Display of AddressBook is filtered by this XML Stylesheet. Two ways to find contacts:
  • ContactPrintout.java finds contact’s last name, then first name, and then backs up the tree to find its Contact node. Other complexElements of the XML, such as PrimaryInfo, HomeAddress, and so on (see AddressBook.xsd for details) are then sent to a recursive method for handling.
  • ContactReport.java extracts just the information of interest, without the element names, and prints details in a narrative style.
• The XML Schema, XML document, and XSLT stylesheet for an AddressBook. Uses XPath expressions to find only certain nodes.
• DTD alternatives to the XML Schema for defining the structure for the AddressBook:
  • contact1.dtd models the data using a few key elements, each with many attributes [this sample XML file uses the DTD]
  • contact2.dtd models the data using primarily elements, each with few attributes [sample XML file]
