Compiling and Running Groovy Scripts Step 5

You are going to want to get familiar with some tools Groovy has outside of Eclipse. You should set your environmental variable to point to Groovy. Open up your environmental variables tab and add a variable called GROOVY_HOME where the value will be something like this: C:\groovy-1.6-RC-3.

One thing about groovy is that is allows you to run the groovy scripts right away without creating a class. You can do this by opening the groovy console. Open a command prompt and type c:\groovysh. When the shell opens, you can type something like this groovy:000> println "Hello World" and that string will print to the console. The disadvantage of the shell is that when you close it, your data is gone.

You can create a groovy script very easily. Create a file called hello.groovy and in the text file, add this line of code: println "Hello World". Save the file and from a regular command prompt (not the groovysh console) type: C:\groovy hello.groovy. You should see "Hello World" print to the console. This can be very helpful because you don't have to create a class to compile some groovy code.

To compile the class you can type groovyc hello.groovy. This command will create a class for you.

Reading a Text File in Groovy Step 4

This post will show you how Groovy can simplify your code.

under your GroovyHelloWorld folder, create a folder called resource.

Under the resource folder, create a file call test.txt and add these lines:

this is a test1
this is a test2
this is a test3
this is a test4

If you want to read these lines from a text file in Java, this is how you would write it:

Create a new Java class under your com.groovy.home called TestFile.java.

In that file, paste the following code:

Make sure you change the path to the location of your test.txt file.

Reading a Text file in Java

package com.groovy.home;

import java.io.BufferedReader;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;

public class TestFile {

public static void main(String[] args)
{
BufferedReader br=null;
try{
br=new BufferedReader(new FileReader("C:\\Programming Tools\\eclipse\\workspace\\GroovyHelloWorld\\resource\\test.txt"));
String line=null;
while((line=br.readLine())!=null){
System.out.println(line);
}
}
catch(FileNotFoundException e){
e.printStackTrace();
}
catch(IOException e)
{
e.printStackTrace();
}
}
}

When you run this code, you will see the lines of your text file print to your console.

In the HelloWorld.groovy file, paste this code in the main class.

Reading a Text File in Groovy

new File("C:\\Programming Tools\\eclipse\\workspace\\GroovyHelloWorld\\resource\\test.txt").eachLine{
line->println line
}

When you run this line of code, you will see the information in the text file print as well. However, Groovy only uses one line of code.

Groovy Simple Pojo Step 3

Groovy makes writing Java code a lot simpler. For example, lets create a simple pojo.

Create a Java class called Person and copy the following code into that class.

package com.groovy.home;

public class Person {

private String firstName;

private String lastName;

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 String toString()

{

return firstName+" "+lastName;

}

}

Paste the following code into your main class in your HelloWorld.groovy class and compile it.

Person p=new Person();

p.setFirstName("Bob");

p.setLastName("Jones");

System.out.println("My Name is: "+p);

This code will create a simple POJO class and print the name of the Person to your console. However, groovy can make this code a whole lot simpler. Copy the code from your Person.java class, delete the Person.java class, create a Person.groovy class and paste the code into that class. When you run your HelloWorld.groovy class, the same information is printed out. Using groovy, you can simplify the Person.groovy class to make it a lot simplier.

Replace the Person.groovy code with this code and you can notice how many lines of code you have just eliminated.

package com.groovy.home

public class Person{

String firstName

String lastName

public String toString()

{

return firstName+" "+lastName;

}

}

All methods for POGOs are public by default and all attributes are private. Each field automatically comes with setters and getters. These methods are auto generated in the byte code and not the source code.

In my next post I will discuss some other Java shortcuts using Groovy.

Oracle Tutorial Part 2

Now we are going to connect to SQL Plus.

Using Window Vista, you will select programs->oraclehome1->application development->sql plus. Your console will open up and you will be prompted for a login and password. We need to login as the administrator the first time so you should input System as the login, and admin as the password. That is because we changed the password to admin when we installed the software. After you login you should see SQL>

To create a user you will type:

SQL>CREATE USER gdias IDENTIFIED BY greg;

You should always end your statements with a semicolin. If you see "User created" then you successfully created a new user with the login of gdias and password of greg.

We want to give this user full access and grant him DBA access.

Input this command to give the user DBA access.

SQL>GRANT DBA TO gdias;

You should see "Grant Succeeded".

Now we want to use the new user that we just created so we are going to connect to that database using the new username and password.

Type this command:

SQL>CONNECT gdias/greg;

Now you are connected with the new user.

Groovy Tutorial Step 1

I am going to start a tutorial on using Groovy and Grails. Groovy can integrate with your Java Code, and can make coding much easier and cleaner. You can change the extension of a Java class to a Groovy extension, and your code will still compile. Groovy will drastically reduce the amount of code you would normally need to write which will make your work much more efficient. IntelliJ is the better IDE to use for Groovy, but you need to purchase a license. Eclipse, however, has a plugin that can be used for Groovy where you don't need to purchase a license. Grails is the web application framework that is used with Groovy, but we will get into that later.

So lets get started.

One of the Top Recovery Sites on the Web

Are you suffering from Alcohol, Overeating, Gambling or any other addiction? InTheRooms Meetings has a database that allows you to find the support group you are looking for in your area. This database consists of the most current Narcotics Anonymous information, Gamblers Anonymous information and Alcoholics Anonymous places to meet. This website allows you to manage the place you meet so other people can find you and get the help they need. This website got its name because most addiction groups are anonymous. People who would run into a member on the street wouldn't say they know them from the AA meeting they attend, but that they know them from “in the rooms”. InTheRooms can help you find a meeting place and if your meeting place isn't listed, you can add it. To add it, you need to create a user name and password so you can login to the system. On their website you are able to search for the meeting you are looking for, and you are able to view the information about the current places to meet. This is a great website to help you get connected with groups who can help you with your addiction. If you need to find a group that can help you, or you want to add your current group, you should visit InTheRooms now.

Oracle 10g Tutorial Part 1

This tutorial is the beginning of my Oracle tutorial series. You first need to install Oracle on your computer. These instructions are for Windows.

This is a tutorial to get you familiar with Oracle and its related technologies. Oracle is widely used for Enterprise applications.

You should download Oracle from this site: http://www.oracle.com/technology/software/products/database/index.html.

I am using Windows Vista for this tutorial so you should download the Oracle Database 10g release 2(10.2.0.3/10.2.0.4) for Microsoft Windows Vista and Windows 2008. If you are using another operating system, then download the version that applies to you.

You will need to accept the license agreement. Download the complete zip files (10203 vista w2k8 86 production db.zip)

You will need to have a username and password to create an account before downloading the software.

After you unzip the folder, execute the setup.exe file.

When the installation runs, you will see radio buttons for basic installation, or advanced installation. I would keep it set as basic installation. You will then need to enter a database password. I will call my password admin and the global database name will be called orcl.

Press next from the product-specific prerequisite check if you do not receive any errors.

Press Install when you reach the summary.

After the installation is completed, change the passwords for Sys, System, and Scott and unlock them. You do this by selecting the password management button.

I am going to change all the passwords to admin since this is a test environment.

press okay and exit to complete the installation.

You should reboot your computer for the changes to take effect.

To test your installation, go to start->programs->Oracle_OraDb10g_Home1->Application Development->SQL Plus

Input Scott as the userid and the password which, in my case, is admin. The host string you will leave blank. That would be used if you are connecting to a database that isn't on your local machine.

You should now be in the Oracle SQL*Plus console.

Problems with Mail Server when IP Address Changes

In an Exchange Server 2003 environment, after the SMTP service is restarted, the Store service is restarted, or the server is restarted, the e-mail recipients may receive old messages that were sent several days before. Or, the e-mail senders may receive Non-Delivery Report (NDR) messages for the delayed e-mail messages that they previously sent.

When this problem occurs, these messages are not visible in the SMTP queues in Exchange System Manager. However, these messages are visible the SMTP Temp tables in the mailbox store. Also, the e-mail senders do not receive an indication that the messages are held by the Exchange Server 2003 server until they receive the NDR messages when one of the services is restarted or when the server is restarted.
When the store starts, the GuidTimestamp is generated on the store side and passed over to Internet Information Services (IIS) store driver (Drviis) through a proxy. However, in some cases, the information that contains the GuidTimestamp is sent to the store driver two times, and IIS receives a different time stamp than the Store receives. When a new message is rendered, the store stamps and submits the messages to the send queue, and then the GuidTimeStamp is changed on the IIS side. Sometimes the messages are not delivered to the next hop on the first try because a remote SMTP host has "Greylisting" enabled. In this case, the SMTP host sends a Temporary Error (4.7.1) message back to the sender that indicates that the sender should retry the transmission of a message in a few minutes. In this scenario, the message is set to a "retry" state by the SMTP service. When the “retry” happens the time stamp on the message is compared with the time stamp of the store driver. When there is a mismatch, the message is considered invalid, and it not delivered until the SMTP service or IIS is restarted.
To summarize, the mail server tried to deliver the messages but reverse dns showed an incorrect address so the mail was not accepted by the remote server and our server sat on it when it was sent information to retry. Because of the timestamp and greylisting (or reverse dns lookup), the message was considered invalid and not delivered until the services were restarted.
