If you need to read properties file in your Spring application all you need is to configure a PropertyPlaceholderConfigurer bean in your application context.
Following example shows how to read property values from a properties file named config.properties. This file needs to be in your classpath so Spring can find it.

Let’s begin by creating a simple Java class that will use the properties values from the file.

package com.zparacha.spring.examples.config;

public class CreateUser {
	//Spring will populate these fields through Dependency Injection.
        private String name;
	private String email;
	private String URL;

	public CreateUser(){}
	public String getName() {
	  return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public String getEmail() {
		return email;
	}

	public void setEmail(String email) {
		this.email = email;
	}

	public String getURL() {
		return URL;
	}

	public void setURL(String url) {
		URL = url;
	}
	public void displayUser() {
		System.out.println("Name=" + this.name);
		System.out.println("Email="+ this.email);
		System.out.println("URL=" + this.URL);
	}
}

Here are two ways to get rid or ^M (Ctrl-M) from your files. More

For PL/SQL developers put_line is a quite useful method. I use it for logging purposes. Recently I found out that the method has an annoying limitation. You cannot print more than 255 characters per line!
Now that is a strange feature. I don’t know what is the reasoning behind this restriction but it does make this method somewhat risky to use. Because if you use put_line to log a string more than 255 characters long it will raise an exception and you program might fail. Unless you catch the exception and continue on with your flow. Obviously no good programmer would want the trouble of adding exception handling code for such a mundane task as logging. So far I have not found an alternative method to print out large string in PL/SQL but I came up with a work around.
I created a little procedure to print large string.

Here is the method. More
