Swing-jdbc
we are developing a swing applicaiton.it is connecting to an oracle 10gr2 database.all database calls are written seperately in a class and conncetions are closed in finaly block.the problem is that on invoking the application few times in a row, the following sql exception is happening
java.lang.NullPointerException
java.sql.SQLException: Listener refused the connection with the following error:
ORA-12519, TNS:no appropriate service handler found
The Connection descriptor used by the client was:
172.16.18.192:1521:oncodms
is it due to some network problem or database server related problem?? or some problem with the code?? ive seen connection pooling in j2ee containers ,is it possible to implement something like that in swing application??
Hi friends.
I'm newer in Java, and i'm searching for 3er party
components (comercial or free), that connects swing
with jdbc (for example, one tablemodel that connects
with jdbc for read and write).
Thank you.Please see http://forum.java.sun.com/thread.jspa?threadID=5123381
Edit: Hey Stupid! That thread is yours. Cripes how stupid can you get....

Crystal Report for Eclipse - Java SWING - JDBC Examples?
<p>Good day! I am just a newbie in Java Programming and I am wondering if there is an example application in SWING-JDBC w/reports that uses Crystal reports w/ Eclipse IDE. As what I have noticed, all of the examples I have seen here are all in jsp and I havent seen anything for swing-jdbc only. I want to try using crystal reports in java. </p><p> </p><p>Do you guys have some examples (even a very simple one) that uses crystal reports with Eclipse and even with a simple database like Access? Any sample, tutorial downloads with this topic? hope you guys can help. thank you very much and God bless.</p>
Crystal Reports doesn't have the same niece tooling for desktop/swing applications that it does for JSP/Web applications. That said you can still create reports with CR4Eclipse and use them in a Swing applications. Try out these samples that I posted. They are all desktop/swing applications. These will work with Eclipse.

Implicit vs explicit close of resultsets and statements?
Hi friends.I am a newbie Java Developer..Okay Here goes
I have just made a LAN based Java application using Swing,JDBC with backend as MS-Access..The backend is on a shared network drive..
The application is distributed as jar files on the LAN PCs..
Everywhere I have connected to the database I have just closed the connection explicitly like this
con.close();
I do not close the associated resultset and statement explicitly
The specification says associated statements and resultsets close when you close
the connection,even if you don't explicitly close them
Also I am not using connection pool..its simple basic connection using DriverManager
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
String url = "jdbcdbcSN name";
String user = "";
String pw = "";
con = DriverManager.getConnection(url, user, pw);
Statement stmt = con.createStatement();
String select = "" ;
ResultSet rows = stmt.executeQuery(select);
On the net everyone says to explicitly close everything..but I did not know that
earlier..
If specification says everything closes on
closing connection why do ppl insist on closing everything explicitly..?
Or is this driver dependent..don't the drivers go through the specification..
My driver is the Sun JDBC ODBC bridge.....
I found this method DriverManager.setLogwriter()
It prints out a trace of all JDBC operations..
So I ran a sample program with this method included...
I redirected output to a log file..
In that program I just explicitly close the connection without closing the
statements and resultsets explicitly...
After running the program and seeing the log I saw that the statements
and resultsets are closed implicitly If I just close the connection explicitly..
I am putting the log file and the code..
Have a look at the end of the log file..
Code
import java.sql.;
import java.io.;
class gc4test
public static void main(String args[])
Connection con = null;
try
FileWriter fwTrace = new FileWriter("c:\\log.txt");
PrintWriter pwTrace= new PrintWriter(fwTrace);
DriverManager.setLogWriter(pwTrace);
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
String url = "jdbc:odbc:pravahcon";
String user = "admin";
String pw = "ash123";
con = DriverManager.getConnection(url, user, pw);
Statement stmt = con.createStatement();
Statement stmt1 = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
Statement stmt2 = con.createStatement();
Statement stmt3 = con.createStatement();
Statement stmt4 = con.createStatement();
Statement stmt5 = con.createStatement();
Statement stmt6 = con.createStatement();
Statement stmt7 = con.createStatement();
String select = "SELECT * FROM Users" ;
ResultSet rows = stmt.executeQuery(select);
ResultSet rows1 = stmt1.executeQuery(select);
while(rows.next())
con.close();

Just closing connection enough?

Till now no performance problems..over 4K records have been added..
JVM is not exiting or anything..
On the net everyone says to explicitly close everything..but I did not know that
earlier..
My question is
Is closing just the connection enough..?
Is there any way I can check whether statements and resultsets have been implicitly closed?
Later on will it cause any performance problems or anything...?
Shud I change my code and add rs.close() and stmt.close() everywhere..?

The memory is not being freed immediately after closing connection explicitly in first 12 iterations..
In the first 12 iterations memory after making connection and memory after closing
connection are the same/or very less difference...
Only in the 13th iteration the memory increases from 4169 to 4817..
Why is this happening..?
I am closing everything explicitly..
Shouldn't the memory be reclaimed immediately..?
Insted it is happening later on..
Am I missing something here..? -
Hi,

Is it possible to make a code editor in Java?
I'm new to java and so i'd like to know if it would be possible to make a simple code editor for Mobile Phones with Java.
The code editor will be for GML.
I'd like to make it so that the code can be easily edited on a wide range Mobile phones (not necissarily smart phones).
If this is possible, I would greatly appreaciate any help or advice. Thanks.

Even day in this forum we see what code looks like when this advice is not followed.my first java code 5 years ago was an applet with a changing 2d function being animated.
it worked after 2 grueling days and i was so happy because visual feedback was my only motivation.
so its hard to say. granted, my code was awful for a long time.I'm thinking of the guy last week who had Swing+JDBC code and kept pestering for help on an obvious syntax error (he was invoking a method with no arguments when it was defined to take a String array) and for the life of him, he couldn't see the error or understand the error message. Posters kept telling him to learn the fundamentals first, but he was stubborn and kept demanding someone fix his syntax error... -
How to automatically generate messages
hello.
as part of the ongoing development of my video library system (done using Java, Swing + JDBC) - i must be able to generate an Overdue Reminder message and a Fine message in the form of JOptionPane messages. in order to do this i must be able read the loan information from my video library database so that i can generate such messages. i have pseudocode already made out for this.
IF ReturnDate is greater than 7th day
Display OverdueReminder
IF Product is not returned after OverdueReminder is issued
Display Fine
IF Fine is not paid
Display AccountDisabledNotice
how can i turn this pseudocode into code?yes. what i have to do now is learn how to generate messages.
thanks for the reply. -

[email protected]I think that it is something wrong with kernel and graphic drivers but i'm not able to solve it from the beginning of using of Arch by me.
I'm not so sure this issue is software-related only because in my case it seems the laptop screen enters power-saving mode (10-min timeout) on its own without any events logged (as shown by dmesg) so my next thought was OK, I'm going to get rid of this issue disabling the screen power-saving timeout in the BIOS and set it to never power down or something like that and from then on managing power mode manually; ie: when I want to power down I will just use systemctl suspend/hibernate which work fine ... problem is: there are no related options in my BIOS for such timeout.
The only timeouts I have are in /etc/systemd/logind.conf set to 30min (#IdleActionSec) (commented) by default so these are not in effect because the screens goes blank after 10m which is less than the (default) 30m in logind. Maybe setting loggind to 9m (un-commented) to catch the event before the machine-default one ?
IdleActionSec=9min
IdleAction=suspend
Will check it and report back. -

Do I need a certificate (and how do I do this) to fill in a grid

As long as the database server and webserver are on the same
machine - no. Even if they are not, use of the Connection
manager (a NET 8 component) will allow you to spoof the RDBMS
connection off to another server while appearing to connect to
the same one, so you would still not need to sign the applet.
How you do it depends on your choice of grid controls and how
you want to access the RDBMS (i.e. using a JBCL type bound
control, or Swing/JDBC with an unbound grid.

SWING GUI blockes when doing a DB action with microsoft nativ JDBC driver
hi,
in a bigger project i have the problem that if i perform a DB action the GUI is blocked. It does not matter if i do the DB Action in invokeLater or
in a SwingWorker or in a new Thread if i call the DB Action and i move another window over my window it is not refreshed.
normally the GUI shouln�t be blocked if i use invokeLater. maybe it
has something to do that i use the native DB driver? I am using JDK
1.4. has anyone ever encounterd the same problem?

}The invokeLater runs the Runnable in the event thread, so yes, that will block your GUI. You ALMOST got the SwingWorker right. DB call in the construct() method -- the construct() method executes outside the event thread, the finished() method executes in the event thread. The only problem is, you did a worker.get() method in your event thread (right after worker.start(0, and get() blocks until result is ready from construct() -- so, bingo, you're jammed up waiting in you event thread.

}here's the code (again, but it doesn't look as ugly as it did earlier on).
i have three programs, only 2 of which can interact with each other. QueryTestTable.java is used with Demo.java to display data in a JTable. the third program is called LogOn.java. i want to use the LogOn.java (username and password for logging on to the system) program in order to be able to use the other 2 programs. i have to be able to use these programs next week. thank you very much.

Swing related question wrongly posted in the JDBC forum
The OP needs some sort of dynamic table model. He does not seem to understand the difference between JDBC and Swing so I am not hopeful for an easy resolution.
The table model used appears to be static so it is not wonder that the new rows are not visible.
I asked the OP to post their questiopn in here several times so far but it seems rather hopeless. Perhaps someone here can help.

JDBC-ODBC Bridge, Swing Components
This program displays information from the Access database Autos.mdb.
Uses the JDBC-ODBC Bridge.
Requires a DSN called Autos pointing to Auto.mdb
I am using the swing components and can't seem to set up my combobox to pull the right data which doesn't display any of the data from the database. I am able to do it using AWT but would like a sleeker look so I am trying to convert. I have made the text bold where I am having the problem. Any insight would be greatful! I am very new to JDBC-ODBC so please go easy on me...

}I am going to help you out but first I would like to advise you not to do this.
Mixing JDBC and Swing (or any GUI for that matter) like this is not the preferred way to proceed. If you want to learn JDBC then command line/shell is fine. If you want to learn Swing learn Swing. When you want to use the two together learn about MVC first.
I am advising you to do this because nobody writes code like this (mixing GUI and database and business logic all in one class). So if you want real world training MVC should be what you look at next.
See http://en.wikipedia.org/wiki/Model-view-controller for more
As near as I can tell your problem is mostly just because you aren't using the combo box correctly. Try
String strManufName = lstManuf.getSelectedItem().toString();it's a bit of a hack but will work for your purposes. What you need in the eend is to use the methods JComboxBox has like getSelectedItem() or getSelectedIndex().
See http://java.sun.com/docs/books/tutorial/uiswing/components/combobox.html for more.
Some other comments.
1) It's nice to see you aren't just swallowing exceptions but some of them are kind of pointless if you just continue on. Like here
try
//Load the MicroSoft drivers
Class.forName ("sun.jdbc.odbc.JdbcOdbcDriver");
catch (ClassNotFoundException err)
//No drivers found
System.err.println("Driver did not load properly");
}And then you continue on with the method. What for? There's no point since the driver didn't load.
2) Please look into the use of PreparedStatements. Very good things those. You can use them in place of your Statements. They are safer but for your purposes help you by you not having to worry about the formatting of data you bind to queries. For example what happens if a manufacturer name contains a ' (single quote) ? Trouble that's what. PreparedStatements make that problem go away.
3) Don't use SELECT *. It is always good practice to put the names of the columns you are selecting. This prevents your code from breaking if the order of the columns should change in any way.
