Web Design

2008-07-17T23:44:48Z

It is good that everyone should have a personal project, like building a tree house, playing sports, or even cleaning the house. What's better for everyone is that they make money off their personal hobbies. Professional website design is one of the best opportunities to make money and have fun while you're at it. After working for nine years, I decided to take on something on the side. I started web design after a friend who works exclusively in computers recommended it. After learning HTML from www.htmlschool.org, I started to create my own website. I also started making money off the site, so I decided to keep with my new project.

Web design is one of the easiest skills to learn. Once you are able to code HTML, using other websites as guides, you should be able to create your own website. And if you decide to put advertising in your websites, you may even make a little money on the side. Of course, it can never substitute a real income, but as you learn more complex forms of web design, you can build on your earnings with more professional style websites. Besides, web design promotes the user's creativity, intelligence, and determination. These qualities are paramount in establishing a useful hobby.

The fact that the internet is one of the most rapidly growing attractions in society is reason enough to begin web design. As more information is added onto the internet, the number of websites increases. It is also likely that one's website will be popular if it holds just the right information that people demand, so it may prove to be profitable for the designer. It's like owning a small business in some aspects, as you are your own boss, you earn money, and you supply a product for the people. Web design is suitable for all ages. A great first step for children to take in starting a job is to begin on the internet, a field that they are both familiar to and talented in. Others may find it as a healthy alternative to a restricted lifestyle, or some may even consider it to be a little financial helper. In any perspective, however, web design is one of the most interesting and popular types of work in the world of today and tomorrow

Re: Is relative addressing possible with a hyperlink component?

SINGLE PAGE CRUD WITH TABLE EXAMPLE

2008-06-24T21:03:44Z

I found a number of errors in this sample app. using Visual Java Server Faces in Netbeans 6.1. This example uses the sample travel data base that comes with the IDE. When running the app, you can select a row to delete and press the delete button, but often times the wrong row gets deleted and the results are often inconsistant; sometimes it works like it should and deletes the proper row, sometimes it doesn't. The add button sometimes adds a new row, sometimes it doesn't. I read the jave code behind the two buttons, and can't figure out what's wrong. Here it is:

public String deleteButton_action() {
// TODO: Process the action. Return value is a navigation
// case name where null will return to the same page.
Iterator rowKeys = selectedTrips.iterator();
while (rowKeys.hasNext()) {
RowKey rowKey = (RowKey) rowKeys.next();
System.out.println("rowKey: " + rowKey);
try {
tripDataProvider.removeRow(rowKey);
} catch (Exception e) {
error("Cannot delete trip with row key " + rowKey);
}
}
// do outside loop because commitChanges() invalidates rowkeys
try {
tripDataProvider.commitChanges();
} catch (Exception ex) {
error("Cannot commit deletions.");
}
return null;
}

/**
* Returns true if the trip for the current row is selected.
*/
public boolean isSelectedTrip() {
TableRowDataProvider trdp = (TableRowDataProvider) getBean("currentRow");
if (trdp == null) {
return false;
}
RowKey rowKey = trdp.getTableRow();
return selectedTrips.contains(rowKey);
}

/**
* Records whether or not the current trip should be marked as selected,
* based on the state of the checkbox.
*/
public void setSelectedTrip(boolean b) {
TableRowDataProvider trdp = (TableRowDataProvider) getBean("currentRow");
RowKey rowKey = trdp.getTableRow();
if (selectedTripCheckbox.isChecked()) {
selectedTrips.add(rowKey);
} else {
selectedTrips.remove(rowKey);
}
}

public String addButton_action() {
// TODO: Process the action. Return value is a navigation
// case name where null will return to the same page.
if ( tripDataProvider.canAppendRow() ) {
try {
RowKey rowKey = tripDataProvider.appendRow();
tripDataProvider.setCursorRow(rowKey);
tripDataProvider.setValue("TRIP.TRIPID", rowKey, nextPK());
tripDataProvider.setValue("TRIP.PERSONID", rowKey, personId.getSelected());
java.util.Date depDate = (java.util.Date) departureDate.getValue();
if ( depDate != null ) {
java.sql.Date date = new java.sql.Date( depDate.getTime() );
tripDataProvider.setValue("TRIP.DEPDATE", rowKey, date);
} else {
tripDataProvider.setValue("TRIP.DEPDATE", rowKey, null);
}
tripDataProvider.setValue("TRIP.DEPCITY", rowKey, departureCity.getValue());
tripDataProvider.setValue("TRIP.DESTCITY", rowKey, destinationCity.getValue());
tripDataProvider.setValue("TRIP.TRIPTYPEID", rowKey, tripType.getSelected());
tripDataProvider.commitChanges();
} catch (Exception e) {

Re: Netbeans design guide

2008-05-28T13:00:44Z

Nothing has changed in the Design time API, so Creator design time API
still holds. Are you saying that the component library worked in 6.0.1
but doesn't work in 6.0 ?

Netbeans design guide

2008-05-28T11:29:48Z

The project I work on develops a component library for Creator, which I have ported to NetBeans 5.5.1.
and now Netbeans 6.0.1. Creator had a design time guide. Has NetBeans updated and released its design time guide? I am having issues with Netbeans 6.1 during design time drag and drop.

Issues with 6.1, drag and drop and component library

2008-05-28T11:26:59Z

The project I work on has developed a component library first for Creator, which I have ported to NetBeans 5.5.1 and now Netbeans 6.0.1. All works fine. When I try to use Netbeans 6.1 drag drop at first seems to work fine. Howeve when I compile the project or Netbeans tries to reparse the project the property page looses all its attribute values for the tag. Though the JSP page still contains the correct attribute values. Does anyone know what is going on?

Visual Editor causes problems when not directly extending AbstractPageBean

2008-05-20T04:30:07Z

I created a more generic class for my page beans which includes some common properties. This class extends AbstractPageBean and is itself extended by the beans created by the Visual Editor.

In the JSP view I can bind the component values to properties of the parent class. But when I try to open the Design view, it says that it can't find these properties in the bean.

Is this a bug?

Re: Null Source in custom component library

2008-04-29T10:27:00Z

So I finally found out what was wrong! Our project is using a content management system that makes everything read-only, and there is a file called index.xml in the lib/complib folder under the project folder that was read-only, so Netbeans couldn't write to it to add the component library to the project, and instead of giving us an error saying that it couldn't write to the file like it usually does, it give us the cryptic (and grammatically incorrect) message, "Unable to embedded a complib into project".

Re: [Help] Upload File Component Problem

I guess this servlet has something to do with showing the image.

Invalidate sessionBean

2008-03-03T09:48:02Z

Hi All,

I have searched around looking for information on invalidating a users session such that the browsers back button cannot be used to revisit pages. Using

FacesContext context = FacesContext.getCurrentInstance();
HttpSession session = (HttpSession) context.getExternalContext().getSession(false);
session.invalidate();

I thought may work but the browsers back button can still access page information. I also use a filter to check on users status which works as it should to make sure the user has logged in correctly. Properly invalidating the session is a problem.

Any guidance appreciated.

How can I get hold of sessionbean1 in a servlet?

2008-02-26T12:45:25Z

Hi,

Say, I have a sessionbean1, which has bunch of cached rowsets. I have a servlet, I'd like to reuse the cached rowset in the sessionbean1. How can I get a reference of sessionbean1 so I can get the rowset?

tried this:
FacesContext cont = FacesContext.getCurrentInstance();
SessionBean1 sessBean1 = (SessionBean1) cont.getExternalContext().getSessionMap().get("SessionBean1");

but won't work.

Thanks
Jimmy

DropDowns inside Table Component

2008-02-20T12:47:25Z

I am trying to access the value in the dropdowns on each row inside table. It should be a simple answer but I can not find an example anywhere. I have a table that I added a column to through table layout that has it component type set to dropdown. So basically a table where each row for that column will be a dropdown. Then I selected the dropdown and use Bind to data to bind it to a database provider or query ( this step is done outside of Table Layout ). All I want to do is get the values for each dropdown in each row when I press a button. There is an expression in Value Expression field in Table Layout that is set for each column when you use static text as component type for column. Should I set this to something in order to get value from dropdown or is there another way to access theses values?

How to use formatted text in a static text/laben(or other) component?

2008-02-13T05:07:10Z

Hello everyone,

my web application reads a String from a SQL Server database which is bound to a static text/label component. The problem is that I don't manage to include line breaks this way.
Is there any way to do it? It doesn't have to be using a static text or label component, I just want to display formatted text on a web page which was read from a database.

Thank you very much for your help,

Arthur

Re: known issue with Table Layout Context Menu

2008-02-12T15:42:21Z

Not sure if this is the correct approach

replace the handlerMethodSource in HtmlDataTableState
actionEvent.setHandlerMethodSource(handlerMethodSource);

with the following update....

ContextMethod preprocessMethod =
pageContext.getContextMethod(methodName, null);
String tmp = preprocessMethod.getMethodBodyText();
