Accessing a Resource in Java


Accessing a Resource in Java

A resource is data(audio, vedio, image, text etc.) that  a program needs to access. Before accessing a resource by a Java program, the resorce is located on the underlying file system. Now, locating a resource on file system inside your project might be tricky for you.

There are following ways to locate a resource on file system from a Java Application-

a) Location dependent

b) Location Independent

Location Dependent

A resource can be located on file-system by specifying a relative url or an absolute url for resource.

C:\Users\yogsha\Desktop\Untitled.jpg
For the eclipse project structure shown in picture, the data files can be accessed from ResourceReader.java as below-

File file1 = new File(“Data1.txt”);

File file2 = new File(“resource/Data2.txt”);

File file3 = new File(“data/com/Data3.txt”);

Apart from this, you have got the option to specify an absolute path of the resource.

File file1 = new File(“C://………../Data1.txt”);

While accessing the resources using the location dependent ways, you are not supposed to change the project folder structure later on because that will lead to change each and every piece of Java code which is involved in accessing these resources.

Well, the Java code change because of resource location change can be avoided by specifying  base location as environment variable. For exmaple – we can have an environment varibale as RESOURCE_BASE  whose value can be set as inside configurations and the variable can be used further inside your Java code to form the complete path for a resource.

String base = System.getProperty(“RESOURCE_BASE”, “”);

File file = new File(base + “/data/com/Data3.txt”);

Location Independent

The methods from Class and ClassLoader classes enable you to access resources independent of their location. Both classes provides similar methods to read system resources and non-system resources for exmaple: getResource and getSystemResource.

Tip :- A system resource is a resource that is either built-in to the system, or kept by the host implementation in, for example, a local file system.)

Using methods from java.lang.ClassLoader

For a System Resource, the ClassLoader methods search each directory, ZIP file, or JAR file entry in the CLASSPATH for the resource file, and, if found, returns either an InputStream, or the resource name. If not found, the methods return null. A resource may be found in a different entry in the CLASSPATH than the location where the class file was loaded.

For a Non-System Resource, the implementation of getResource on a class loader depends on the details of the ClassLoader class. Generally,all class loaders first tries to locate the resource as a system resource; if not found, the behavior is dependent on the ClassLoader class.

ClassLoader class exposes two sets of methods – one set returns URL of the accesses resource while other resturns InputStream.

Examples:

Data3.txt can be accessed from ResourceReader.java as–

URL url = ResourceReader.class.getClassLoader().getResource(“com/Data3.txt”);

Here the value of url will be the absolute path of file Data3.txt on file system. Note – the file Data3.txt is on classpath. Data2.txt is not available on classpath and hence cant be accessed using getResource mehod.

Data3.txt can be read as InputStream as below-

InputStream file = ResourceReader.class.getClassLoader().getResourceAsStream(“com/Data3.txt”);

Using methods from java.lang.Class

The method getResource() returns a URL for the resource. The URL (and its representation) is specific to the implementation and the JVM (that is, the URL obtained in one runtime instance may not work in another). Its protocol is usually specific to the ClassLoader loading the resource. If the resource does not exist or is not visible due to security considerations, the methods return null.

If the client code wants to read the contents of the resource as an InputStream, it can apply the openStream() method on the URL. This is common enough to justify adding getResourceAsStream() to Class and ClassLoader. getResourceAsStream() the same as calling getResource().openStream(), except that getResourceAsStream() catches IO exceptions returns a null InputStream.

Client code code can also request the contents of the resource as an object by applying the java.net.URL.getContent() method on the URL. This is useful when the resource contains the data for an image, for instance. In the case of an image, the result is an awt.image.ImageProducer object, not an Image object.

The getResource and getResourceAsStream methods find a resource with a given name. They return null if they do not find a resource with the specified name. The rules for searching for resources associated with a given class are implemented by the class’s ClassLoader. The Class methods delegate to ClassLoader methods, after applying a naming convention: if the resource name starts with “/”, it is used as is. Otherwise, the name of the package is prepended, after converting all periods (.) to slashes (/).

Important:- Observe the difference between behaviour of getResource() method from Class class and ClassLoader class. The method from Class class resolves the resource name as explained above and finally delegates it to ClassLoader.getResource().

9. Port availability

	Port 80, 1935, 40000, 40001, 40002 , 40005 must be free in the machine on which you intend to install Dimdim Web Meeting Server.

	The Dimdim Servers use ports 80 &1935 for external communication. But port 80 alone is enough to be opened for external communication.
	In addition, ports 40000/ 40001/ 40002 / 40005 must be free for internal communication.

DIMDIM INSTALLATION:
====================

Installation Steps:

Step 1: Download dimdim rpm package

Step 2: Install rpm package by typing the command rpm -ivh Dimdim-4.5_SF_i386.rpm in a terminal

	Dimdim-4.5 will be installed under location /usr/local and a soft link for dimdim will be created under /usr/local.

        The place holder will exactly look like
        --- usr
          |
          |--local
          	|
          	|--dimdim
          		|
          		|--ConferenceServer
			|
          		|--CobrowsingManager
          		|
          		|--DTP3
          		|
          		|--MediaServer
          		|
          		|--red5
          		|
          		|--nginx
			|
			|--ThirdPartyPackages

Step 3: By default, ip address of ethernet 0 interface of the box is configured for Dimdim Server.

	i) To stop Dimdim, open a terminal and enter stopDimdim
	ii) To start Dimdim, open a terminal and enter startDimdim.

	To start the meeting do
	http://<ipaddress>/dimdim/

Note: If the ip address is not the same or if you need to configure with different IP address, follow the below steps:

Step A:	Get the IP Address of the machine

 	Example:
      		root@localhost dimdim]# ifconfig eth0

      		The output will look like:
	         	  eth0      Link encap:Ethernet  HWaddr 00:0C:29:CA:FA:7C
		          inet addr:192.168.1.10  Bcast:125.255.255.255  Mask:255.0.0.0

		The IP Address for the above example is 192.168.1.10

Step b: Configure all the Dimdim components

		There may be two cases:
		1. Network has public and private IP mapping,

			ExternalIP:port --> Internal:port

				Please note that port should be same, Port 80 is recommended.
				For example: 123.X.X.X:80 ---> 192.168.X.X:80
					publicIP is mapped to privateIP

			Use Config-ipaddress.pl like below
				cd /usr/local/dimdim
				./Config-ipaddress.pl 123.X.X.X 80 192.168.X.X

		2. VM has a singleIP, There is no network mapping(no Network Address Translation):

			Use Config-ipaddress.pl like below
				cd /usr/local/dimdim
				./Config-ipaddress.pl 123.X.X.X 80

Step c: On completion of configuration, open a terminal and enter the command "startDimdim". This will start all the Dimdim components.
To ensure all Dimdim Components are started, check the status of the Dimdim Components.

You are now ready to start meeting. Start the meeting by providing the URL http://<IPAddressORHostnameConfigured>/dimdim/.
Please note the trailing slash is required in the URL after dimdim.Example http://192.168.1.10/dimdim/

Dimdim Sever Machine Restart:
=============================

When the machine where Dimdim Server installed is restarted,
	open a terminal and type startDimdim - This will start Dimdim Server

Dimdim SMTP Server Configuration :
==================================

Please note that the current smtp settings are just sample setting. It is adviced that you change these settings to your own smtp configuration.

Below is suggested way to modify the smtp configuration

1) Open dimdim.properties configuration file

Go to folder cd /<dimdim_home>/ConferenceServer/apache-tomcat-5.5.17/webapps/dimdim/WEB-INF/classes/resources/

i.e. cd /usr/local/dimdim/ConferenceServer/apache-tomcat-5.5.17/webapps/dimdim/WEB-INF/classes/resources/

2) Modify the below settings as suggested. Please note that setting "dimdim.smtptype" needs to be configured depending on the type of smtp server.

##	Email Parameters that can be configured by the user.
##
email.server=<gmail smtp server address>
email.user=<your gmail id>
email.password=<your gmail account password>
email.sender=<your gmail account id>
email.PORT=465
email.EMAIL_CC=
email.EMAIL_BCC=
##
##
email.PROTOCOL=smtp
email.DEBUG_MAIL_SESSION=false
email.BUFFER_SIZE=2048
email.EMAIL_SUBJECT = has invited you to a Dimdim web meeting.
email.EMAIL_FROM_PERSON=DimDim Invitations

##  2 : SSL SMTP Server  i.e. gmail SMTP Server
dimdim.smtptype=2
##
##

DIMDIM UNINSTALLATION:
======================

Step 1:	rpm -e 	dimdim

	All the Dimdim Components installed by rpm package will be removed.

Note:
	    1. Please don't try to change the IP Address or port numbers for the Dimdim components by directly
	       going to the components' folder.

	    2. This Dimdim pack is only for 32-bit Operating System machines.

    	3. This is tested with CentOS 5.2.

Problems:
1. First free port 80 on server
Port 80, 1935, 40000, 40001, 40002 , 40005 must be free to install Dimdim Web Meeting Server.

so, just stop apache service running on port 80….
# service httpd stop
# /etc/init.d/httpd stop

2. Skip OS check
DimDim – Dimdim-4.5_SF_i386.rpm require CentOS 5.2 … if you want to install it on CentOS 5.3 then have to skip OS check ?
There is a file which check OS “/etc/issue”

# vi /etc/issue
here replace CentOS release 5.3 (Final) to CentOS release 5.2 (Final)

3. Change IP:Port
# cd /usr/local/dimdim
# ./Config-ipaddress.pl 123.X.X.X 85

here you have changed IP to 123.X.X.X and port to 85

Wow!!… now you have your own web based seminar (webinar) server where you launch multiple meetings simultaneously 🙂
