I have a table and want to change the row color with a colorPicker. The result of the colorPicker is a Hex code like #ff0000 and it works, but i cant change the color of the row regard of the result of the colorPicker.

My solution is creating styleSheet's for each colors, but i have more than 200 colors...

If you have an idea, please let me know. Thank you.

Hi Rick,

public String getColumnStyle() {

TableRowDataProvider trdp = (TableRowDataProvider) getBean("currentRow");
RowKey rk = trdp.getTableRow();

// get actual row count
SoilLayer layer = getSessionBean1().getLayers()[Integer.parseInt(
rk.getRowId())];

return "background-color: "+layer.getColorRGB(); // return Color in HEX
}

I hope it helps.

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

Problem with table component NB 6.1

2008-07-14T10:57:38Z

Hi, I got a problem when running an visual web application in Netbeans 6.1. In the JSP page I dragged a table component binding the data from a MySQL database. Everything works good but when I check my application in a browser (firefox 3), the table doesn't appear.

When I look the html source code this is what i got..

....
<head>
<title></title><script type="text/javascript">var webui_suntheme4_2={"webuiJsfx":false,"webuiAll":false,"theme":{"locale":"en-us"},"ajax":{"isJsfx":true},"isDebug":false,"isStyleSheet":true,"parseOnLoad":true};</script><script
...
<div id="form1:table1" style="position: absolute; left: 168px; top: 120px">
<div style="width:0px">
<table id="form1:table1:_table" class="Tbl_sun4" width="100%" border="0" cellpadding="0" cellspacing="0"

As you can see the HTML code is cut in the table component, but when I drag just a table component without any binding ,from a database for example, the browser show me the table with the default values.
Do I have to set anything else in NetBeans or it's just a matter of the browser??

P.D. I'm using Ubuntu

Hi Whale Web,

One thought is that this prompt may be due to a proxy server,
ie, the system is asking for the proxy user and password.

The IDE's 'Tools | Options | General' panel provides options for
configuring the Proxy Settings (see options.png below).

When using manual settings, clicking on the 'More' button leads to the
Advanced Proxy Options dialog (see proxy.png below) where more options
such as the Username and Password for Proxy Authentication can be set.

Does this help?

Re: Drop down list values from both Database and custom

2008-07-01T04:15:42Z

First, I wouldn't use the default options list. It's really just a placeholder for the options you want.

In your case, I suggest using an object list data provider and binding your dropdown list to that.

The following link shows you how to create the data provider: http://blogs.sun.com/winston/entry/objectlistdataprovider_workaround

Could you provide us with the code you used? Also could you include where you put the code; for example, prerender, processValueChange, etc.

Is the list data bound? What is the data type of the value field binding.

Does the value field need a converter, which it does for anything other than a String?

Greetings Glenn,
My experience with Visual Web, while at times frustrating, is overall positive. I now have several active applications in production, all of them exclusively based on VWP. For right now, my user base is small, but that will change in the near future - hence my concern with your comment. Could you elaborate as to why you limit VWP to prototyping, and not deployment?

rrugemalira,
My apologies for taking over your posting!

/David

ICEfaces (icefaces.org) has a chart component that can be used with the
visual web editor (although generally speaking, I would not recommend
the visual web editor for anything except prototyping).
