Hi All,

What's your question? You made two statements -- not a question in sight.
What socket exception are you encountering?

Is java free?

I need to write application for my company, it will use jdbc, swing, xml, all from standart J2EE JDK. Do I need to pay anything and what license should I use?

Even if I will sell my programm? Yes! Of course, you are not allowed to sell the JRE itself as if it was your program. But you can of course sell your own program based on the JRE.

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.

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....

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.

Coding Swing Applications with Large JDBC ResultSets

Hi,
Does anyone know where I can find information regarding efficient ways to code Swing UI's with large JDBC result sets. I have been using JTextArea but my application seems to constantly run out of memory when I encounter a large result set. Also, any information regarding threading and if running database queries should be done entirely off the event thread vs SwingUtilities.invokeLater() would be of tremendous help.
Thanks,
John Meah

If doing operations in the awt thread starts to impair the performance of your app, then create a new class that implements Runnable, and do this:
Thread t = new Thread (new yourRunnable());
t.start();
t should have lower priority than the AWT thread.
As far as large result sets, it is a fairly universal problem. My recommendation is that you arbitrarily impose a limit on how many of the records returned are displayed, like maybe 25 records. This should fix your problem

Swing - Jdbc Components

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.

Crystal Report for Eclipse - Java SWING - JDBC Examples?

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.  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.

Crystal Reports doesn't have the same niece tooling for desktop/swing applications that it does for JSP/Web applications.Â That said you can still create reports with CR4Eclipse and use them in a Swing applications.Â Try out these samples that I posted.Â They are all desktop/swing applications.Â These will work with Eclipse.

Oracle JDBC and Swing Applets

Hi
I'm trying yo connect to an oracle databse using the oracle thin driver
in a Swing Applet deriving from JApplet class using a JTable .
Note my browser is Swing enabled and i can view normal swing applets.
But i get an error which says
Oracle/jdbc/driver/oracel/driver not found
But if i run this as an application instead of a swing applet it works
Remember it's a Swing Applet not a normal Applet.and the oracle driver works in a normal application.this error occurs only when the oracle driver is used in a Swing Applet.
any ideas?

I re-read your problem , your problem is as same as me.
So, unzip classes12.zip oy folder /htdocs/ on your server
, when this file is unziped it will create the necessary
folders and files so your program will find the drivers
classes and I think your problem is solved.
Thanks Jamanir

JDBC with Swing ?

Hi,
I want to build a Java application that accesses an Oracle database. I want the fields of that form (JTextField) to be somehow "assocated" to the database's table so that whenever I update the field all I have to do is a save (or commit).
I know Borland has a bunch of tools like that (com.borland.dx.dataset), but I want to stay away from that Borland-specific stuff.
Is that possible to do with the Rowset Implementation ? Do I need something else ?
Thanks !

Here is what I mean :
Let say you have a JFrame with a few JTextFields and JCheckBox, and you want to have a simple query returning the results into those fields.
Then, after modifying the value of those fields, you want to click on Save.
Is there a way to show the query data in those fields and "post" the changes without saying : JTextField value goes to that table column, etc.
Something like :
jtextfield1.assignToTable("MYTABLE");
jtextfield1.assignToColumn("PRODUCT_ID");And whenever I update or requery this database table, the associated fields would get populated automatically.
Regards,
Alexandre
