JDBC :: CallableStatement Stored Procedure Call Cancellation?
Feb 19, 2015I have a very complex oracle stored procedure that searches and retrieves some data. The procedure returns an output parameter - an oracle cursor. I execute the procedure by JDBC:
CallableStatement stmt = conn.prepareCall("{call myprocedure(?,?,?,?}");
The problem is, the queries can sometimes take quite long (few minutes) and i would like user to be able to cancel the query anytime by clicking button. I have reference to stmt object, but unfortunatelly calling stmt.cancel() (from other thread) has NO EFFECT.
On the other hand when i change the CallableStatement sql to some query like:
CallableStatement stmt = conn.prepareCall("select * from all_objects");
I get
"java.sql.SQLTimeoutException: ORA-01013: user requested cancel of current operation" after calling stmt.cancel()
- so thats the right reaction.
Does that mean than i cannot cancel stored procedure call via jdbc, but only simple select statements? I guess i could cancel the query by oracle kill session, but i use connection pooling (jboss) and i have plenty of sessions for the same user existing.
Database Product Version is Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production JDBC Driver Version is 11.2.0.4.0

Java Stored Procedure - Connecting To 8i Database
Sep 17, 2014I am new to Java Stored Procedures. There is a PL/SQL package in our legacy application(Oracle 9i) which pulls data from Oracle 8i source database through a DB link. Now we have upgraded our databas to Oracle 11g R2 from 9i. So the DB lint to Oracle 8i will no longer work in 11g. Hence I have created a Java stored procedure that establishes JDBC thin connection to the source 8i database. I have loaded the java stored procedure in the database using loadjava and have created a call specifaction.
I have called this java stored procedure inside the PL/SQL package. Now while executing the PL/SQL package, it takes the default driver ojdbc6.jar to establish JDBC connection and fails to connect to the 8i database giving ArrayIndexOutOfBounds Exception. While running the code in the linux application server with classes12.jar the code succeeds. But when the same is called in the database it fails.
1. How can I make my PL/SQL call use classes12.jar while calling the Java Stored Procedure?
2. How can I load the jar file(which includes my classes and the classes12.jar) into the datase as one object? (When I tried to load the whole jar, in database the classes and dependent jar loaded separately)
3. Is there a way to use classpath while calling the Java Stored Procedure like how we do from Unix?

JDBC :: Disconnected Rowset From Select Inside Stored Procedure?
Apr 21, 2015I am using CachedRowSet returning it from a parameterised select statement and it works fine.
If I put the same select statement into a simple read-only stored procedure then I get this exception: "A result set was generated for update".
I am not trying to update the rowset in my code.
I tried to make the CachedRowSet to be read-only but it does not work, same error.
Question 1 : can a stored procedure returning a single result-set be called to populate a read-only CachedRowSet? (in a similar fashion to a CallableStatement prepareCall method with input/output parameters).
Question 2: in general is using CachedRowSet, WebRowSet, FilteredRowSet (disconnected) and JDBCRowSet (connected) something to be encouraged for future develpment or are they deprecated, or replaced by something else/better??

Swing/AWT/SWT :: Where Is Event Source Object
Feb 28, 2015java.awt.Component is an abstract class, and it's direct Sub-classes are Button, Canvas, Checkbox, Choice, Container, Label, List, Scrollbar, Text Component
So, when I use addXListener(mylistenerclass m);//which is a method of Component class which object is holding the list of all listeners, for a particular Event Source?
I am under the assumption that - there is an Event Source Object(possibly static) for every Event Source type(mouse, keyboard etc) that holds a list of destinations(classes that implements their listener interface) - added to the the object via addXListener method. When an event happens(mouse click, drag etc) the Event Source Object creates an Event Object and send it to all the destinations. Is my assumption correct? I can't seem to find the location or declaration of Event Source Object and the list where it stores it's registered destinations.

Mastermind Game - Comparison Event
Jan 14, 2015I'm not so new to java i know the basics. I want to make a mastermind game. Just for training purpose.
Now i am at the comparison phase where it is comparing your chosen "colors" with the actual "color code"
This is my code for that part:
guesChars is a char array of 4 of the actual code
readGuess is a string of 4 of which the players has filled in the console
goodGuess is a char at the right position with the right "color"
avgGues is a char with the right "color" at the wrong position
Java Code:
for(int i = 0; i < guessChars.length; i++){
for(int ii = 0; ii < readGuess.length(); ii++){
if(readGuess.charAt(ii) == guessChars[i]){
if(ii == i){
[Code] .....
The problem is when the code is for example
ACDD
and the player guess is
ADDD
Result is
2 right spot right color
1 right color wrong spot
It have to be
2 right spot right color
0 right color wrong spot
