Using a JSpinner in JBuilder

I am new to using JBuilder and I am trying to use a JSpinner in my application but I am unable to compile and I get this message:
"Frame1.java": Error #: 300 : class JSpinner not found in class testing.Frame1 at line 41, column 3
I am using JBuilder 6 with java virtual machine java.vm.version 1.3.1-b24 and I am have the following import statements:
import java.awt.*;
import java.awt.event.*;
import javax.swing.event.*;
import javax.swing.*;
import javax.swing.table.AbstractTableModel;
import java.util.Hashtable;
import javax.swing.JScrollPane;
Is there any way for me to use a JSpinner with this version of JBuilder or any advice, please help. Thanks.

HI... Try JBuilder 8 & jdk 1.4.1. Im not sure but i think that the JSpinner wasnt implemented all the way in jdk's past 1.4

Can I use BI Beans with Jbuilder?

hi
Can I use BI Beans with Jbuilder Instead of JDeveloper.

Is there a separate download for this (a version that will work with any J2EE IDE, I'm using JBuilder X)? When I tried to install the BI Beans download, it failed because it was looking for a version of JDeveloper.
Yes, BI Beans are J2EE compliant components and will
work within any J2EE compliant IDE. However, as
JBuilder does not support the JDeveloper wizard
driven development paradigm you will experience the
same level of productivity using JBuilder.

Using debug mode with jbuilder 4 (or other tool) and wl 6.0

Hello,
I would like to know if there is a way to use jbuilder environnement to
debug ejb deployed on WL. I would like to be able to set break points into
my source code and be able to display variables values.
If it is not possible with jbuilder, is it possible with an other tool ?
If not, how can you debug ejb ? For exemple if I want to be sure a specific
line has been callde, do I need to stop my server, insert a system.out,
redeploy my ejb and restart my WL or is there a more simple way to do it ?
Thank's.

Using PreparedStatements and getting a database connection are two different things. JBuilder ain't gonna write that PreparedStatement for you. Does it create the database and tables for you for any database, too? I've never used it, so I don't know.
Which database will you be using?
Bad idea to depend on JBuilder, IMO. Learn how to do it without JBuilder and you'll always know how. Depend on the IDE to do everything for you and you're helpless without it.
Look at the JDBC tutorial under the Tutorials link to the left if you want to see how PreparedStatements are used. - MOD

I can not use jdk1.5 in JBuilder

I am using JBuilder X,when i change my jdk to 1.5,it shows below:
"MainPanel.java": cannot access javax.swing.JPanel,bad class file: C:\tools\j2sdk1.5.0b1\jre\lib\rt.jar\javax\swing\JPanel.class,class file has wrong version 49.0, should be 48.0,Please remove or make sure it appears in the correct subdirectory of the classpath. at line 21, column 32
who knows the reason?

Please, folks. Google before you post!
This has been covered hundreds of times since 1.5 came out, even during its Alpha days.
Basically, the bottom line is that you cannot easily use JBuilder with 1.5. If you cripple parts of JBuilder (like disabling editor syntax checking, living with inconsistent or no auto-indentation, and using only Ant builds), you can stumble along.
Visit the JBuilder developer's site (http://community.borland.com), and search for OpenTools (Jbuilder extensions). One of them allows you to use JDK 1.5 with JBuilder's compilation system, but the other two still apply, and will always apply until JBuilder supports 1.5 syntax in its builtin parser in the editor.
Oh, and you will never be able to debug 1.5-compiled code, if you generate 1.5 binaries (i.e. if you tickle any part of the 1.5 extensions). JBuilder X itself runs only on 1.4.2_0x, and thus can only debug classes which can be run by a 1.4.2 VM (i.e. no 1.5 classes).

Which one do you use? eclipse, vaj, jbuilder.....

Hi, everyone
I just want to have a general idea which IDE is preferred by
most of us.
Actually, I use Context.

Run java class using JBuilder

hi,
I already import the java class forder to the src folder in JBuilder where the src folder is created by the JBuilder itself. When i run compile the program there is an error in reading the java class file but when i run the program in Textpad, the program is success. May i know why? how can i run my program using java class in JBuilder instead of Java source? Thanks.

In JBuilder there is an option of specifying what the 'main' file in a project is . Specify that to this class file
[ What I mean is , in many java files we can define 'main' method , but we will intend to execute the main of one file only for a project . In JBuilder specify this file as the main class file ]

Hi: just to add on....
I'm using j_security_check to authenticate my system login and I'm facing a problem with the redirection after verifying the user credentials.
When the user enters a valid userid and correct password, the system hangs at j_security_check. The displayed URL is something like "/cst/LoginMainServlet/j_security_check". It fails to authenticate and re-direct to the AuthError.html page as defined as error page in the web.xml

Can't make an alarm that is set more than 24 hours in future with JSpinner

I have what I thought was a simple problem, but I can't seem to get past it, so I come to ask the experts.
I want to use a JSpinner to basically set an alarm. I am using the SpinnerDateModel and a DateEditor with the string "HHH:mm:ss". The reason there is three hour feilds is because what I really want is to be able to set it to any number of hours from 0 to 999. But there in lies my problem, it won't let me get past 24.
What I have tried:
I changed the first H to D (or d, whichever is days in the year) but it wont work for me because it can't be zero.
I tried extending the DateEditor code, but this was next to impossible because the company I work for makes us have two machines on our desk, both are thin clients, one connects to the internet but we are not allowed/able to download anything, and it does not have java on it in any form. The other does not connect to the internet, and can not, it has Java on it, but not the source code for methods like DateEditor. So without seeing the source I have no clue what to override.
I really want to use the one JSpinner with the SpinnerDateModel, but if I can't figure this out then I could use seperate spinners for hours, minutes, and seconds though that looks really ugly and is far from ideal.
So please if anyone has any clue how I could solve this, please let me know.
Thanks,
JSG

I just tried out a JSpinner with the SpinnerDateModel and DateEditor using pattern "HH:mm:ss". Behind the scenes, you are still dealing with a date. If you look at what date gets returned, the first time you spin the spinner using that pattern, the year suddenly jumps to 1970. It's using a default year, because there is no year to spin within your pattern.
So long as you don't feel too guilty or uncool for using the date spinner in a manner that it was not intended, you could probably achieve your objective by abusing the date editor with a pattern like "SSS:mm:ss". That pattern is milliseconds (which conveniently go from 0 to 999), minutes, then seconds. When reading your spinner, just interpret the milliseconds as the hours, minutes as minutes, and seconds as seconds. The rest of the date just gets thrown away. Uncool. But should work.
Or you can be cool and write a custom editor and model, but depending on your experience level, this could be difficult and time consuming. But also comes with a greater feeling of achievement.

Hello,
the *.jar file thing is a common problem in Java. One simple solution to the problem is by saving the *.jar file in the C:\j2sdk1.4.0\jre\lib\ext\ folder. This directory is an extension to the regular java files and by doing this, java will look in this directory if you import some other files not included in the java package. This does not work if you are using JBuilder, couse JBuilder installs its own jsdk, which is uses, probably under the JBuilder folder.

Where are Tomcat Java server pages stored in JBuilder 4?

From what I understand JSP pages should be saved into the ROOT directory of Tomcat.
I have created a JSP page in Jbuilder 4 but when it saves, it is somewhere entirely different.
If I right click on the JSP in Jbuilder 4 and select webrun it runs in Jbuilder fine.
However if I try and run it from IE7 browser with address http://localhost:8080/hello.jsp I get a message saying internet explorer cannot display the page.
I also did a search on my C drive to find the tomcat ROOT directory but could not find it.
So what do I need to do in Jbuilder4 to be able to view my developed JSP pages in a browser?
Thanks,
Jason.

New solution for Limit the value in JSpinner with changable max/min value

I have ever stuck with a problem like that :
1. My application need to get two int value A and B that user input.
I use two JSpinner with Number format model.
named in jSpinnerFrom (A value get from) jSpinnerTo (B value get from)
2. The request is that :
two value can be any Integer, But the value of (B - A) can not more than 1000.
I use changeListener added into the JSpinner, when use set value make (B-A) larger than 1000, I set value back.
But when user press mouse on arrow button, the value will be increase automaticaly, and at last the value can not set back that make (B-A) not larger than 1000.
3. So I get the BasicArrowButton of the jSpinnerFrom and jSPinnerTo,
and add a mouselistener on the arrowbutton. When mouseReleased, then chen the value (B-A), if it is larger than 1000, then set it back the proper value.
Thus I can make the min/max value in the JSpinner be changable, and limit the two input value be in range of 1 - 1000
Post this wish be help for any one has thus familar request.
Good Luck!!

Something like this might work
import javax.swing.*;
import java.awt.*;
import javax.swing.event.*;
class Spin extends JFrame implements ChangeListener
JSpinner spinner1;
JSpinner spinner2;

    spinner1.addChangeListener(this);
    spinner2 = new JSpinner(new SpinnerNumberModel(0, 0, 1000, 5));

Custom JSpinner Model / Editor

Hello,
This question may have been answered in the past but I could not find anything. I am trying to use a JSpinner for cycling through pages of information. I would like the display to show current page of total number of pages, i.e. 1 of 10. I would also like the user to be able to enter a number and have the spinner display that number in the same format. I am not quite sure if I need to create a custom model and editor or expand the SpinnerNumberModel. Any guidance is much appreciated.

this might be one way for the '1 of 10', for entering a number, just add a keyListener,
and modify the methods accordingly

import java.awt.*;
import java.awt.event.*;

JTextField tf;

int currentPage;

    tf.setHorizontalAlignment(JTextField.RIGHT);
    tf.setEditable(false);
    tf.setBackground(Color.WHITE);
    spinner = new JSpinner();
    spinner.setUI(new MyUI());
    spinner.setEditor(tf);
    changeValue(1);
    JFrame f = new JFrame();
    f.getContentPane().add(spinner);

      tf.setText(newPageNumber+" of "+TOTAL_PAGES);
      currentPage = newPageNumber;

JSpinner Number Display Format

Hello,
I am using a JSpinner with a SpinnerNumberModel to display an integer whose range
is 5000 to 9,999 (incremented by 1). The JSpinner shows the current number as an
integer with a comma (i.e. 6,300). Is there an easy way to remove the
comma from the JSpinners display? (i.e 6300).
Thanks!
Michelle
