visitIBIZA!

Hi folks,

this is my second article on travel. It is about IBIZA! One of the most popular islands in Europe! It is known to be the island of entertainment/fun.

SAN ANTONI is the most touristic place of the island. EN BOSSA is known to be one of the best coasts of Ibiza as well, however EN BOSSA is full of local people instead of tourists. I advice you to book a hotel in SAN ANTONI. We chose an all-inclusive hotel - Hotel San Remo in SAN ANTONI. The hotel is nice with its swimming pool and its bar was close to the pool. You can enjoy your cocktails while watching the bright see. By the way the hotel was so close to the see, just a 30 seconds walk.

Location of the hotel was perfect however I cannot say the same things for its meals. We did not like the meals. Each time we found something to eat but I wish they were better. Next time I will book the same hotel without all-inclusive option.

Cafe Mambo and Cafe del Mar are the most popular cafes where you can watch sunset. After the sunset, they turn into a club. People dance in the club and on the beach.

"Drinking your mojito while watching sunset" is a tradition in Ibiza. First day, we went to Cafe Del Mar and ordered our Mojitos. Found out that a Mojito is 13 euros! Second day, we got our mojitos somewhere else but it was not as nice as Cafe del mar's. I can say that the mojito worths every penny we pay :)

We walk along the coast till Cafe Del Mar. It is about 2,5 km from our hotel. We enjoyed the walk, took photos, drank our glass of cocktail, watch the boats...

Most of the clubs (Ushuaia, Hardrock cafe, ...) are close to EN BOSSA side. Island is not as big as Mallorca. (Mallorca may be my next travel article ;) ) You can rent a moto and sightsee the island with it. Very funny!

Amnesia, Space and Ushuaia are some of the well-known clubs in Ibiza. Everyday a popular name takes stage in the clubs. You should choose one and attend! strongly recommended! We went to David Guetta in Ushuaia. Mondays are David Guetta-days. Cocoon, Fifty Cent, Tiesto, Robert Tickle are some other people having programs in Ibiza. Please buy your tickets online before you go to Ibiza. You may not find a ticket on the event day. Or it may be more expensive than the online ticket.

Water sports is another funny activity.

Transportation in Ibiza is easy. Buses are perfect for the transfer from airport to hotel and vice-versa. We took L9 for going to the hotel from airport. We haven't used taxi for 4 days! There is even a DiscoBus taking you to the clubs. Each club is one stop :) Everything is considered for fun/entertainment :)

PL/ SQL

PL/SQL stands for Procedural Language extension of SQL.

Oracle uses a PL/SQL engine to processes the PL/SQL statements. A PL/SQL code can be stored in the client system (client-side) or in the database (server-side).

PL/SQL Block consists of three sections:

• The Declaration section (optional).
• The Execution section (mandatory).
• The Exception (or Error) Handling section (optional)

DECLARE 

     Variable declaration 

BEGIN

     Program Execution 

EXCEPTION

     Exception handling 

END;

Advantages of PL/SQL 

1. Block Structures: PL SQL consists of blocks of code, which can be nested within each other. Each block forms a unit of a task or a logical module. PL/SQL Blocks can be stored in the database and reused. 
2. Procedural Language Capability: PL SQL consists of procedural language constructs such as conditional statements (if else statements) and loops like (FOR loops). 
3. Better Performance: PL SQL engine processes multiple SQL statements simultaneously as a single block, thereby reducing network traffic.
4. Error Handling: PL/SQL handles errors or exceptions effectively during the execution of a PL/SQL program. Once an exception is caught, specific actions can be taken depending upon the type of the exception or it can be displayed to the user with a message.

Later, I'll add a presentation prepared by me...

when my kids will be born... ;)

Very good idea ;)

visitbrussels!

Hi,

I will present you a list of to do's in Brussels which is my favorite city in Europe!

1. Please see "Atomium" and "be.welcome" which is very similar to "iamsterdam".
2. In "Mini Europe", there are tiny miniatures of the most popular attractions(for ex: Eiffel Tower...) in Europe. I say them miniatures, however if you photograph them people can think that you are really in Paris!
3. You can go to "Grand place" by walking from the central train station. Grand place is really grand, and its architecture is wonderful! You should not miss to see "Manneken Pis" (the peeing boy) which is the symbol of Belgium.
4. Warandepark is full of trees, you can rest there for a while. It is very close to the central train station!
5. Delirium. One of the most popular bars in the world. It is said that there are more than 3000 types of beers there! You should try Kriek which is a special cherry-beer.
6. In the road to Delirium, there is a peeing girl - Jeanneken Pis.
7. In the road to Delirium, there is a restaurant named Chez Leon, famous with its mussels.
8. One of the most famous meals in Belgium is "Carbonade". You can try it in Brussels Grill.
9. You should eat waffle in Brussels. If you will go to Brugge, eat it in Brugge :)
10. There is Autoworld in Jubelpark. It is one of the most popular car fairs in Europe. JubelPark is also a nice park to see and rest.
11. Did you know that Cedric and Redkit are from Belgium? Have you ever watched their cartoons when you were a child? If yes, then you should visit "Belgium Comic Strip" museum, very close to the central train station.
12. If you have time in your belgium travel, you should visit Brugge. Highly recommended! You can think that in Brugge you are in a fairytale!
13. If you have more time, you can visit Ghent. There, you can drink your gassy white wine near the river. If you have more more time :P, you can visit Antwerp famous with its castle and harbour.

I've already seen the places I've written above. There are of course more places to sightsee:

1. Terrace of "Bibliotheque Royale".
2. Botanique Park
3. Hardrock Cafe Brussels.
4. Laken famous with its Chinese and Japanese architecture and restaurants.

4. Çin ve Japon mimarisiyle ünlü Laken.

Gördükten sonra detaylı bilgiyi veririm.

Son olarak cikolatanin da anavatani belcika :) cesit cesit cikolata stoklayip dön ebilirsiniz:D

OpenJPA

The tutorial from which I learnt openJPA was mentioning about Apache Derby. I have written a small intro about Apache Derby in the following link ;)

Data is the most important part of all programs. We have been using databases and SQL statements for years. However, better approaches exists! Especially object-oriented approaches for data persistence is very useful.

Some examples: EJB, JDO, Hibernate, Toplink... (The last 2 are object-relational mapping tool)

Java persistence API = JPA (standard)

first introduced as a part of EJB 3.0.

openJPA is another solution for data persistency. There are 3 artifacts:

1. entity class
2. persistence.xml (in src/META-INF)
3. A class through which you will insert, update or find an entity.

• Firstly, we should download openJPA from the following link:

http://openjpa.apache.org/downloads.html

• Then add the jars to the project's build-path.

Let's say we have a DB table CUSTOMER:

NAME	PK?	TYPE	NULL?
CUST_ID	Y	INTEGER	NOT NULL
FIRST_NAME		VARCHAR(50)	NOT NULL
LAST_NAME		VARCHAR(50)
STREET		VARCHAR(50)
APPT		VARCHAR(20)	NOT NULL
CITY		VARCHAR(25)
ZIP_CODE		VARCHAR(10)	NOT NULL
CUST_TYPE		VARCHAR(10)	NOT NULL
LAST_UPDATED_TIME		TIMESTAMP	NOT NULL

Now we should have an entity class like this:

package entity;

import javax.persistence.*;

import java.io.Serializable;

import java.util.Date;

/*

 * CUSTOMER ENTITY CLASS

 */

@EntityListeners({CustListner.class})

@Entity(name = "CUSTOMER") //Name of the entity

public class Customer implements Serializable{

@Id //signifies the primary key

@Column(name = "CUST_ID", nullable = false)

@GeneratedValue(strategy = GenerationType.AUTO)

private long custId;

@Column(name = "FIRST_NAME", nullable = false,length = 50)

private String firstName;

@Column(name = "LAST_NAME", length = 50)

private String lastName;

@Embedded

private Address address = new Address();

@Column(name = "CUST_TYPE", length = 10)

private String custType;

@Version

@Column(name = "LAST_UPDATED_TIME")

private Date updatedTime;

//Getters and setters

public long getCustId() {

return custId;

}

public void setCustId(long custId) {

this.custId = custId;

}

public String getFirstName() {

return firstName;

}

public void setFirstName(String firstName) {

this.firstName = firstName;

}

public String getLastName() {

return lastName;

}

public void setLastName(String lastName) {

this.lastName = lastName;

}

public Date getUpdatedTime() {

return updatedTime;

}

public void setUpdatedTime(Date updatedTime) {

this.updatedTime = updatedTime;

}

public Address getAddress() {

return address;

}

public void setAddress(Address address) {

this.address = address;

}

public String getCustType() {

return custType;

}

public void setCustType(String custType) {

this.custType = custType;

}

// ToString()

public String toString() {

      StringBuffer sb = new StringBuffer();

      sb.append("custId : " + custId);

      sb.append("   First Name : " + firstName);

      sb.append("   Last Name : " + lastName);

      sb.append("   customer type : " + custType);

      return sb.toString();

   }

}

And here is the sample persistence.xml 

<properties>

            <property name="openjpa.ConnectionDriverName" 

                value="org.apache.derby.jdbc.EmbeddedDriver"/>

      <property name="openjpa.ConnectionURL" 

                value="jdbc:derby:C:/Users/tr1t6321/ipeks"/>

            <property name="openjpa.ConnectionUserName"  value=""/>

            <property name="openjpa.ConnectionPassword" value=""/>

            <property name="openjpa.Log" value="DefaultLevel=TRACE"/>

        </properties>

!!! persistence.xml should be in src/META-INF.


......Inheritance.....
1.  @Table(name="CUSTOMER")
@Entity(name = "CUSTOMER") //Name of the entity
@Inheritance(strategy=InheritanceType.SINGLE_TABLE)
@DiscriminatorColumn(name="CUST_TYPE", discriminatorType=DiscriminatorType.STRING,length=10)
@DiscriminatorValue("RETAIL")

2. @Table(name="CUSTOMER")

@Entity(name = "CUSTOMERJOINED") //Name of the entity

@Inheritance(strategy=InheritanceType.JOINED)

@DiscriminatorColumn(name="CUST_TYPE", discriminatorType=DiscriminatorType.STRING,length=10)

@DiscriminatorValue("RETAIL")

3. @Table(name="CUSTOMER")

@Entity(name = "CUSTOMERTABLE") //Name of the entity

@Inheritance(strategy=InheritanceType.TABLE_PER_CLASS)

Let's insert some customer....

public static void main(String[] args) {
EntityManagerFactory entityManagerFactory =  Persistence.createEntityManagerFactory("testjpa");

EntityManager em = entityManagerFactory.createEntityManager();
EntityTransaction userTransaction = em.getTransaction();

userTransaction.begin();
//inserting Customer
Customer customer = new Customer();
customer.setFirstName("Charles");
customer.setLastName("Dickens");
customer.setCustType("RETAIL");
customer.getAddress().setStreet("10 Downing Street");
customer.getAddress().setAppt("1");
customer.getAddress().setCity("NewYork");
customer.getAddress().setZipCode("12345");
em.persist(customer);
userTransaction.commit();

OpenJPAEntityManager oem = OpenJPAPersistence.cast(em);
Object objId = oem.getObjectId(customer);
Customer cust = em.find(Customer.class, objId);

em.close();
entityManagerFactory.close();
System.out.println("Customer info: " + cust);

}

Some crucial points:

!!! While running your java project with openjpa; put the following argument to

Run > Run configurations> arguments

VM box: -javaagent:D:/apache-openjpa-2.3.0/openjpa-2.3.0.jar

Note: codes are from http://www.javaworld.com/article/2077817/java-se/understanding-jpa-part-1-the-object-oriented-paradigm-of-data-persistence.html. Thanks.

Apache Derby

Apache Derby, an Apache DB subproject, is an open source relational database implemented entirely in Java and available under the Apache License, Version 2.0. Some key advantages include:

• Derby has a small footprint -- about 2.6 megabytes for the base engine and embedded JDBC driver. 
• Derby is based on the Java, JDBC, and SQL standards. 
• Derby provides an embedded JDBC driver that lets you embed Derby in any Java-based solution. 
• Derby also supports the more familiar client/server mode with the Derby Network Client JDBC driver and Derby Network Server. 
• Derby is easy to install, deploy, and use.

I used it while I was working with OpenJPA about which I will write a tutorial later.

1-Anyway, please download Derby from:

http://db.apache.org/derby/derby_downloads.html

2- In windows;

set DERBY_INSTALL=C:\Apache\db-derby-10.10.2.0-bin

3-In windows;

set CLASSPATH=%DERBY_INSTALL%\lib\derby.jar;%DERBY_INSTALL%\lib\derbytools.jar;.

4-In windows;

C:\> cd %DERBY_INSTALL%\bin 

C:\Apache\db-derby-10.10.2.0-bin\bin> setEmbeddedCP.bat

5- If you put the jars in your classpath; then you can run this comment from anywhere in your computer:

> java org.apache.derby.tools.ij

After this command you can create new databases, run sql files and sql statements etc...

for example: 

connect 'jdbc:derby:/home/bill/databases/MyDbTest';

disconnect;

!!! If you do not disconnect from the table, the java project running from Eclipse cannot connect to the Database and it throws exceptions.

Erken baslayan dogumgunu :P
