XYlayout

I am using XYlayout in my code.
I am importing it from
import com.borland.jbcl.layout.*;
But when I am executing my code I am getting this error.
"package com.borland.jbcl.layout does not exist"
SO what I have to do to overcome this problem....

JBCL has been deprecated by Borland.
It is still available for backwards compatibilitybut
has to be manually enabled inside JBuilder inorder
for it to be available to your project (and to be
included in your completed application).
How do I do this?read Teh Docs ™ - or don't do it. JBCL is a proprietary library, you're best off avoiding it. yet another reason people shouldn't use an IDE right away :-)

Applet not finding oracle.jdeveloper.layout.XYLayout. How to add to jar?

hey guys, i have created an applet and it is unable to find oracle.jdeveloper.layout.XYLayout. How might I add this to my jar to be able to deploy it?

not.
Figure out what jar it's in, and add that jar to the classpath for the applet (and thus to the webserver in a location where the applet can load it from).
See the documentation to figure out how to set an applet classpath.

Deploy XYLayout

Hi everyone,
i developed an application using XYLayout and deployed it to a jar file. But whenever i start to jar file i get an error message saying "java.lang.NoClassDefFoundError: oracle/jdeveloper/layout/XYLayout". Where can i find the xylayout classes or what can i do to include them in the jar file?
Thanks!

Hi,
add jdev-rt.jar from jdev\lib to your deployment (at least for dependency checking)

XYlayout don't work with Java web start

I have created a simple application that display a 2 form, the second form
use oracle XYLayout. so far it works fine, than I put the application as
a Java web start, however I got an error message saying

I'm sure I added the jdev-rt.jar to the Java web start jar file.

Hi,
I have been able to solve the problem
I have put my application on seperate tar and
jdev-rt.jar on another tar.
on the jnlp file I change to

it's working fine now.

JBuilder2005 and XYLayout

Hi
I got a problem when I was using jbuilder2005.
I designed the user interface using XYLayout that comes with jbuilder2005. It can run within jbuilder2005 and everything looks good.
But once I run this program via command line, the error happens like this: java.lang.NoClassDefFoundError:com/borland/jbcl/layout/XYLayout
The jbcl.jar that is including the class above has been added into the classpath.
Can anyone help me solve this problem?
Thanks.

File and FileInputStream problem

Hi all
I have downloaded from developpez.com a sample code to zip files. I modified it a bit to suit with my needs, and when I launched it, there was an exception. So I commented all the lines except for the first executable one; and when it succeeds then I uncomment the next executable line; and so on. When I arrived at the FileInputStream line , the exception raised. When I looked at the code, it seemed normal. So I want help how to solve it. Here is the code with the last executable line uncommented, and the exception stack :

Thank you very much

One easy way to send a file through RMI is to read all bytes of a file to a byte array and send this array as a parameter of a remote method. But of course you may have problems with memory when you send large files. The receive is simillary.
Other way is to split the file and getting slices of the file, sending slices and re-assemble at destination. This assume that the file isn't changed through the full transfering is concluded.
I hope these could help you.

Need help Take out the null values from the ResultSet and Create a XML file

hi,
I wrote something which connects to Database and gets the ResultSet. From that ResultSet I am creating
a XML file. IN my program these are the main two classes Frame1 and ResultSetToXML. ResultSetToXML which
takes ResultSet & Boolean value in its constructor. I am passing the ResultSet and Boolean value
from Frame1 class. I am passing the boolean value to get the null values from the ResultSet and then add those
null values to XML File. When i run the program it works alright and adds the null and not null values to
the file. But when i pass the boolean value to take out the null values it would not take it out and adds
the null and not null values.
Please look at the code i am posing. I am showing step by step where its not adding the null values.
Any help is always appreciated.
Thanks in advance.

} Please tel me where is my mistake or maybe you knew another way to open JInternalFrame with public method form another class

Some possibly helpful suggestions:
1) Create one JDesktopPane, and do it in the constructor of GUI. You should call this constructor only once.
2) Get rid of GUII. The GUI constructor will do all this and more.
3) Get rid of startFrame and startFrame2.
4) In GUI2, change your width and height to static variables if you are going to use them in outside classes. There is no reason to have to create a GUI2 object just to get those values. Get them from the class, not the instances.
5) You're doing something funky in your Top class with your mixing of static code and non-static code. My gut tells me that Top is just a static universe that exists to get your code up and running, and that the code within it should all be static, but that's just my personal opinion.
6) In MyInternalFrame, get the height and width from GUI2 (if that's what you want to do) again in a static fashion. Rather than new GUI2().width which makes no sense, use GUI2.width.
Why can't you put the button inside of the JInternalFrame object? I believe that the contentPane of this object which may hold your button (unless you embed a jpanel) uses BorderLayout, so you have to take care how you add jcomponents to the jinternalframe (or more precisely, it's contentPane).

HOW TO: Create a GUI "Hello World"


This document describes how to create and run a very simple "Hello World"
Java GUI app using JDeveloper. The application will have one button and one
text field. Clicking the button will populate the text field with the message,
"Hello World!"
Creating The New Application
In this section, we will create an application with an empty frame.
<ol>
[*]Choose File | New Workspace.
</li>
[*]Choose File | Save Workspace.
</li>
[*]Enter <TT>HelloGui.jws</tt> as the name for the workspace.
This creates a Workspace called HelloGui. A workspace organizes all the projects
you need to work on at one time.
</li>
[*]Choose File | New Project.
The Project Wizard opens. This wizard will help you create a new project called
HelloGui. A project contains all the files that go together in one "tier"--for
example, all the files belonging to a single Java Application client, or all
the files belonging to an Enterprise Java Bean. Because we are working on
a simple, one-tier application, we will only need one project in our workspace.
</li>
[*]If the Welcome page appears, click Next.
</li>
[*]On the Project Type page, in the What is the Project's Filename?
field, change the filename to <TT>HelloGui.jpr</tt>. Leave the rest of the
path the same.
</li>
[*]Select A Project containing a new... and choose Application
from the dropdown list.
</li>
[*]Click Next.
</li>
[*]On the Project Options page, in the What is the name of the project's
default package field, enter <TT>helloGui</tt>.
</li>
[*]Click Next.
</li>
[*]On the Project Information page, you can enter any information about your
project that you wish.
</li>
[*]Click Finish.
The Application Wizard opens.
</li>
[*]In the Class field, enter <TT>HelloApp</tt>.
</li>
[*]Select the New Empty Frame radio button.
</li>
[*]Click OK.
The Frame Wizard opens.
</li>
[*]In the Class field, enter <TT>HelloFrame</tt>.
</li>
[*]Click OK.
JDeveloper creates an application, <TT>HelloApp</tt>, containing an empty
frame, <TT>HelloFrame</tt>. The source code for these classes appears in the
Navigator, which is the upper left-hand pane in the JDeveloper IDE.
</li>
[*]Choose File | Save All.</li>
</ol>
Adding a Panel to the Frame
In this section, we will now add a panel to the frame. In the next section,
we will add all the other components to this panel.
<ol>
[*]In the Navigator, double-click <TT>HelloFrame.java</tt>.
A viewer opens. This viewer has four tabs at the bottom:
<ul>
[*]Source, the currently active tab, which displays the source code
of the selected class</li>
[*]Design, which invokes a visual layout designer</li>
[*]Class, which invokes an editor for the class' attributes, and
can help you stay JavaBean complient</li>
[*]Doc, which displays the class' JavaDoc
</li>
</ul>
</li>
[*]Click the Design tab.
The viewer now displays a grey square, a graphical mock-up of your frame.
Also, on the right-hand side of your screen, the Property Inspector opens.
This allows you to quickly set attributes and define events for components.
</li>
[*]In the component palette (the tabbed toolbar near the top of your screen),
select the Swing Containers tab.
</li>
[*]Click the blue square (described in rollover text as <TT>JPanel</tt>) and
click on your frame to add the panel.
The Property Inspector now displays attributes of the JPanel.
</li>
[*]In the Property Inspector, click twice inside the box beside the name
field.
</li>
[*]Change the name to mainPanel.
</li>
[*]Click the box beside the layout field.
</li>
[*]Choose XYLayout.
XYLayout is an easy-to-use Layout for prototyping. Later, we will change the
layout to a more portable one.</li>
</ol>
Adding Components to the Panel
In this section, we finish laying out a prototype UI. We will add polish and
portability to the UI later.
<ol>
[*]In the Component Palette, select the Swing tab.
</li>
[*]Select the <TT>JTextField</tt> component, which looks like a text field
with a cursor.
</li>
[*]In your panel, click and drag the cursor to outline the text field.
Don't worry if the text field doesn't have exactly the right size or position.
We will adjust these later.
The Property Inspector now displays attributes of the JTextField.
</li>
[*]In the Property Inspector, change the name (just as you did for the
JPanel) to <TT>displayField</tt>.
</li>
[*]Change the text to nothing (erase the value that is already there).
</li>
[*]In the Component Palette, select the <TT>JButton</tt> component, which looks
like a button being clicked.
</li>
[*]In your panel, click and drag the cursor to outline the button.
The Property Inspector now displays attributes of the JButton.
</li>
[*]In the Property Inspector, change the name and action command
to helloButton.
</li>
[*]Change the text to <TT>Say Hello!</tt>.
</li>
[*]Choose File | Save All.</li>
</ol>
Wiring Up the UI
In this section, we wire the UI so that clicking the button causes "Hello
World!" to display in the text field.
<ol>
[*]In the Property Inspector, select the Events tab.
</li>
[*]Click the box next to the Action Performed field and press the Enter
key.
This creates a method, <TT>helloButton_actionPerformed()</tt>, which will
be invoked when the button is clicked, and displays the source code for the
method stub in the viewer.
</li>
[*]In the viewer, add the following command to the body of the method:
<TT>displayField.setText("Hello World!");</tt>
</li>
[*]Choose File | Save All.</li>
</ol>
Testing the Prototype Application
<ol>
[*]Choose Run | Run "HelloApp".
Your application appears, with a blank text field and a button labeled "Say
Hello!"
</li>
[*]Click the button.
The text "Hello World!" appears in the text field.
</li>
[*]Close your application.</li>
</ol>
Refining the UI
In this section, we polish the UI so that the components have the right size
and alignment, the text in the text field shows up red, and the panel uses the
portable GridBag layout instead of the JDeveloper-specific XYLayout.
<ol>
[*]In the viewer, select the Design tab.
</li>
[*]Select your text field.
</li>
[*]Drag the edges of your text field until it is the size you want.
</li>
[*]Drag the center of the text field until it is the vertical position you
want.
</li>
[*]Right-click the text field and choose Align Center.
This centers your text field horizontally in the frame.
</li>
[*]In the property inspector, click the box next to the foreground field.
</li>
[*]Click the ellipses (...).
A color editor appears.
</li>
[*]Select Red from the dropdown list.
</li>
[*]Click OK.
</li>
[*]On your frame, select your button.
</li>
[*]Drag the right edge of your button until it is the horizontal size you want.
</li>
[*]Select your text field, and multi-select your button by control-clicking
it.
</li>
[*]Right-click your button or text field.
</li>
[*]Choose Same Size Vertical.
This sets the height of all selected components to that of the first selected
component (the text field).
</li>
[*]Right-click your button or text field.
</li>
[*]Choose Align Center.
This aligns the center of all selected components to that of the first selected
component (the text field).
</li>
[*]Select your panel by clicking anywhere on the grey background in the visual
designer.
</li>
[*]In the Property Inspector, click the box beside the layout field.
</li>
[*]Select GridBagLayout from the dropdown list.
</li>
[*]Choose File | Save All.</li>
</ol>
Running the Finished Application From Within JDeveloper
<ol>
[*]Choose Run | Run "HelloApp".
Your application appears, with a blank text field and a button labeled "Say
Hello!"
</li>
[*]Click the button.
The text "Hello World!" appears in the text field, in red.
</li>
[*]Close your application.</li>
</ol>
Deploying the Application to Your File System
<ol>
[*] In the Navigator, right-click <tt>HelloGui.jpr</tt> and choose New Deployment
Profile.
The Deployment Profile Wizard opens.
</li>
[*]If the Welcome page appears, click Next.
</li>
[*]On the Delivery page, select Web Application or Command-Line Application
from the dropdown list, and click Next.
</li>
[*]On the Staging Area page, in the Deployment Destination field, enter
<tt><JDeveloper>/HelloGui</tt>, where <tt><JDeveloper></tt>
is your JDeveloper root directory. Click Next.
</li>
[*]On the Project page, select all the <tt>.java</tt> files and click Next.
</li>
[*]Skip the Archive page and Applet Tags page by clicking Next on each.
</li>
[*]On the Libraries page, shuttle all libraries from the Project Libraries
list to the Deployed Libraries list, and click Next.
</li>
[*]On the Finish page, name the profile <tt>HelloGui.prf</tt>, and click Finish.
</li>
[*]When JDeveloper asks you if you want to deploy now, click Yes.</li>
</ol>
JDeveloper will archive your application files and copy this archive and all
other required libraries to <tt><JDeveloper>/HelloGui</tt>.
Running the Application from the Command Line
<ol>
[*]Open a command-line prompt.
</li>
[*]Enter the following script.
Note: You may want to create a batch file containing this script. Be
sure to replace JDeveloper_Home with your JDeveloper home directory.
<pre>set __CLASSPATH_ROOT_DIR__=JDeveloper_Home\HelloGui
set CLASSPATH="%__CLASSPATH_ROOT_DIR__%\HelloGui.jar"
set CLASSPATH=%CLASSPATH%;"%__CLASSPATH_ROOT_DIR__%\xmlparserv2.jar"
set CLASSPATH=%CLASSPATH%;"%__CLASSPATH_ROOT_DIR__%\classes12.zip"
set CLASSPATH=%CLASSPATH%;"%__CLASSPATH_ROOT_DIR__%\jdev-rt.zip"
set CLASSPATH=%CLASSPATH%;"%__CLASSPATH_ROOT_DIR__%\swingall.jar"
cd JDeveloper_Home\HelloGui
jre -cp %CLASSPATH% helloGui.HelloApp</pre>
</li>
[*]Your application appears, with a blank text field and a button labeled "Say
Hello!"
</li>
[*]Click the button.
The text "Hello World!" appears in the text field, in red.
</li>
[*]Close your application.</li>
</ol>

Hello,
I followed your instruction step by step to make this "Hello World", but when I run it, I got message "cannot find the runable node". What do I miss here? Thanks.

How can I control the size of a cell in the GridBagLayout?

Hi,Swing Gurus
I am developing a swing-based program using JBulider5 enterprise.
It seems to me that the GridBagLayout is really a hard nut!
How can I control the size of a cell in the GridBagLayout?
It seems that I cann't control the size of a cell directly.
But how the size of a particular cell is determined when I switch the layout manager from XYLayout to GridBagLayout?
Thx in advance!
Regards,
Justine

hi,i have not done what you are asking but there are fields like
COLUMNWIDTH, MINSIZE, MAXGRIDSIZE, PREFEREDSIZE to which you can set the appropriate values and test for your need.hope this helped.bye martian.

Getting error while running jar file

Hi,
I am getting below error while running the jar file
"Exception in thread "main" java.lang.NoClassDefFoundError: oracle/jdeveloper/layout/XYLayout:"
I have created a simple ADF desktop app in which i am displaying the frame.I created the jar from Jdeveloper.
Please help..

How do you run the jar file? Take a look at this thread for a possible a solution: Re: deploying a jdeveloper adf application to a desktop
Is the class XYLayout packaged or referenced? Take a look at this thread: XYlayout classes - can I distribute with my code?

Hi Experts.
I need some help. I'm trying to display JTextAreas in a table using the TableCellRenderer interface. My problem is that I have to display more than one line in each row (I need linewrap). I think the tables cell size prevents the expansion of the JTextArea. I've posted my code and marked the important places:
