Linux raid 1: remove failure disk and mount the healthy disk

Hi,
if you’re using this guide mean you’re in trouble 😦 ….
Suppose you have raid 1 with two partition in two different disks an one of them it’s failing. Before to go ahead make a backup of the healthy disk.
Suppose you have a partion

/dev/sdd

Now you want to remove the raid and eject the healthy disk

Glassfish: Create Oracle jdbc resources

Hi everyone,
this time we’re going to create two oracle’s jdbc: one normal and one XA. XA connection allows to have a global transaction in a multi database context.
First of all we need to include oracle driver in glassfish server.
Copy the ojdbc14.jar file into the domain-dir/lib/ext directory and restart glassfish.
Now connect to glassfish admin console http:://localhost:4848 and click on Connection Pool to create a new one

Flex4: Using XMLListCollection in a list

In this blog I’m going to show how to handle a xml list and how to show it
First add resultFormat="e4x"

<s:HTTPService id="categoryService"
					   url="http://www.flexgrocer.com/category.xml"
					   resultFormat="e4x"
					   result="handleCategoryResult(event)"/>

After declare a bindable variable.The Bindable metadata tag tells Flex to watch this particular collection for changes.

<![CDATA[
			import mx.events.FlexEvent;
			import mx.rpc.events.ResultEvent;
			import mx.collections.XMLListCollection;
			[Bindable]
			private var categories:XMLListCollection;
			
			private function handleCategoryResult(event:ResultEvent):void{
				categories = new XMLListCollection( event.result.category );
			}
		]]>

Now Create a s:List in the s:controlBarContent

<s:List left="200" height="40" dataProvider="{categories}" labelField="name">
			<s:layout>
				<s:HorizontalLayout/>
			</s:layout>
		</s:List>

and the result is

GWT: create a combo filled by database data

In this blog I’m going to show how to display a combo filled with database data.
First of all create a simple presenter

package com.biancama.test.gwt.webapp.client.presenter;

import java.util.List;

import com.biancama.test.gwt.webapp.client.ServiceLocator;
import com.biancama.test.gwt.webapp.shared.dto.EmployeeDTO;
import com.google.gwt.event.shared.HandlerManager;
import com.google.gwt.user.client.Window;
import com.google.gwt.user.client.rpc.AsyncCallback;
import com.google.gwt.user.client.ui.HasWidgets;

public class ComboBoxPresenter extends AbstractPresenter {

	private final Display display;

	public ComboBoxPresenter(ServiceLocator serviceLocator,
			HandlerManager eventBus, final Display display) {
		super(serviceLocator, eventBus);
		this.display = display;
	}

	public interface Display extends TopDisplay {
		void setData(List<EmployeeDTO> data);
	}

	@Override
	public void go(HasWidgets container) {
		bind();
		container.clear();
		container.add(display.asWidget());

		serviceLocator.getEmployeesService().getAllEmployees(
				new AsyncCallback<List<EmployeeDTO>>() {

					@Override
					public void onSuccess(List<EmployeeDTO> data) {
						display.setData(data);

					}

					@Override
					public void onFailure(Throwable arg0) {
						Window.alert("Error getting all employees");

					}
				});

	}

	private void bind() {
		// TODO Auto-generated method stub

	}

}

Spring 3: Managing Transactions Programmatically without template

In this blog I’m going to show how to manage a transactional code with the simplest feature of spring.
First of all have a look to Spring 3: Implement CRUD pattern using hibernate session factory.
Now I’m going to build a simple interface to add a new Employee

package com.biancama.spring3.service.hibernate;

import com.biancama.spring3.model.hibernate.Employees;

public interface EmployeesService {
	public boolean addNewEmployee(Employees employee);
}
