Types of RAM

2009-05-04T00:33:58Z

SRAM (static RAM) is random access memory (RAM) that retains data bits in its memory as long as power is being supplied. Unlike dynamic RAM (DRAM), which stores bits in cells consisting of a capacitor and a transistor, SRAM does not have to be periodically refreshed. Static RAM provides faster access to data and is more expensive than DRAM. SRAM is used for a computer's cache memory and as part of the random access memory digital-to-analog converter on a video card.

Dynamic random access memory (DRAM) is the most common kind of random access memory (RAM) for personal computers and workstations. Memory is the network of electrically-charged points in which a computer stores quickly accessible data in the form of 0s and 1s. Random access means that the PC processor can access any part of the memory or data storage space directly rather than having to proceed sequentially from some starting place. DRAM is dynamic in that, unlike static RAM (SRAM), it needs to have its storage cells refreshed or given a new electronic charge every few milliseconds. Static RAM does not need refreshing because it operates on the principle of moving current that is switched in one of two directions rather than a storage cell that holds a charge in place. Static RAM is generally used for cache memory, which can be accessed more quickly than DRAM.

DRAM stores each bit in a storage cell consisting of a capacitor and a transistor. Capacitors tend to lose their charge rather quickly; thus, the need for recharging. A variety of other RAM interfaces to the computer exist. These include: EDO RAM and SDRAM.

SDRAM (synchronous DRAM) is a generic name for various kinds of dynamic random access memory (DRAM) that are synchronized with the clock speed that the microprocessor is optimized for. This tends to increase the number of instructions that the processor can perform in a given time. The speed of SDRAM is rated in MHz rather than in nanoseconds (ns). This makes it easier to compare the bus speed and the RAM chip speed. Website Design can convert the RAM clock speed to nanoseconds by dividing the chip speed into 1 billion ns (which is one second). For example, an 83 MHz RAM would be equivalent to 12 ns.

Re: Validate two components together

Have you tried using virtual forms? I dont know if they're available in 6.1, but 6.5 definitely has them.
With virtual forms, you can submit parts of the user input.

Saving / loading data with SessionBean

2008-12-31T10:03:32Z

Hi,

I have two pages:
- user login page
- user menu page

The user passes by the login page and, if OK, I store a serializable User obj in the session bean:
User usr = etc
SessionBean sb = getSessionBean();
sb.saveData(AppConsts.BEAN_USER, usr);
Later, in the menu page, I try to access it:
SessionBean sb = getSessionBean();
User usr = (User) sb.retrieveData(AppConsts.BEAN_USER);
For some reason I dont know, I always get null when trying to retrieve that object in the menu page!!!

Right after sb.saveData, I verified that indeed sb.retrieveData gets the right obj.

Any idea of what's going on? What do I miss here?

Thanks, Don

newbie - Lifecycle explanation for Visual Web?

2008-10-21T09:31:14Z

I am not only new to JSF, Netbeans, and Visual Web, I am completely new to web app development period!

I have done some Visual Web tutorials and trying stuff on my own, but am unfortunately confused about the total lifecycle of the web app, when does what get called

- i.e. in the Page Beans, when are the various methods called, init, preprocess, prerenderer, etc, and what state is the bean in during those points? There are some nice comments for the methods but I'm just not completely comprehending the flow and data lifecycle.

By any chance would someone be able to point me to a document that thoroughly discusses how these beans and methods are used and the lifecycle of the processing of the pages?

or provide a brief synopsis?

Sorry for the really raw question, thanks for any guidance!

How can i use the jsf woodstock's renderer (HTML renderer) in another web project

I want to personalize the development process of the modules of an electronical health record , so i create some netbean's plugin that generate JSF files for a "health record module" . The problem is the rendering process , the jsp's pages of the generated module project doesn't render the pages to drag and drop the components into it. So i want to know what file or configuration i have to change to preview the jsf pages (JSF/HTML renderer of the woodstock project) in design time , on netbeans.

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

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 {

}

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 tried not to use it but it won't display the image I uploaded.
I guess this servlet has something to do with showing the image.
Anything I can do?

can you used the fileupload without:

ServletContext theApplicationsServletContext = (ServletContext) this.getExternalContext().getContext();
this.realImageFilePath = theApplicationsServletContext.getRealPath(IMAGE_URL);

can you used the fileupload without:

I did fix imports and it says nothing to imports
What I don't get is reformat, I tried Ctrl + Shift + F but it will display Find Dialog Box..

. You add import statements to fix these errors
Right-click in the Java Editor and choose Fix Imports
, you can press Ctrl-Shift-F to reformat the code.

Dear gurus,
I tried to follow example given in netbeans 6.0 kb about file upload component.
I have an error on line:
ServletContext theApplicationsServletContext = (ServletContext) this.getExternalContext().getContext();
it says cannot find symbol getContext();
I tried to remove the getContext() but it says inconvertible types.
Anybody can please help me?
