this is to upgrade snd modify a java program with JDBC with 5 simple task.
1. Get the program to work so that you can run queries against your marks data table.
2. The example code opens a database connection, uses it to prepare then submit a SQL query, and then closes the connection. This is inefficient.
Modify the code so that the database is opened by the main program, and then used to prepare the SQL query. The prepared statement object should be made accessible for use by the QPanel object. The database connection should be closed when the program terminates. Test your modified program.
3. Modify the SQL query and the QPanel class so that the program can instead be used to identify all students who obtain a specified grade (HD, ..., F) on these data. Test your modified program.
4. Add another query panel that allows retrieval of data for a student identified with a given identifier, or for all students having a specified name. Test your modified program.
5. Try rewriting the code so that it works with [url removed, login to view] objects rather that [url removed, login to view] objects.
zip file contains 2 document files in it. speficifation has the absolute spefication of the work that need to be done..including the current condition of the program n the demonstration code has all the codes for the program.
the system should run under an unix or sun compatible environment.n it use sql. if u have JDK 1.4.2 then it should have support it.
once again..i have the complete code here..n all it needs is to update n modify the code for the task explained above.
this is a very very simple problem..n i need it as soon as possible..in 2-4 days..
1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.
2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request.
3) Exclusive and complete copyrights to all work purchased. (No GPL, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site).
sun java or unix..jdk 1.4.2 is enough to support the sql on it..if u dont have sql running on ur system..i can try it in my system..
