Eclipse And Jdk

To setup Eclipse to use the JDK you must follow these steps. Download the JDK. First you have to download the JDK from Suns site. Install it and it will save some files to your hard drive. Eclipse Preferences. Go to the Eclipse Preferences - Java - Installed JREs. Eclipse is a java program in itself. It will run even if you just have JRE and not JDK. But the purpose of Eclipse as an IDE is for Java development for which you need JDK (java development kit). The Eclipse Foundation - home to a global community, the Eclipse IDE, Jakarta EE and over 375 open source projects, including runtimes, tools and frameworks. Double-click on your hard drive, and within that, double click on the 'Applications' folder. Drag your eclipse folder from the Desktop into this folder. Inside your eclipse folder is an Eclipse application; its icon is a purple circle with three white stripes. Click the Eclipse icon to launch the IDE.

Maven requires Eclipse using a JDK, i.e. Java Development Kit, instead of a Java Runtime Environment (JRE). The main difference is that a JDK also contains a Java Compiler and other tools to develop Java Code, while the JRE is only able to run compiled Java applications.

To check with what Java version (JRE or JDK) Eclipse is running, do the following:

  • Open the menu item Help > About Eclipse. (On the Mac, it’s in the Eclipse-menu, not the Help-menu)
  • Click on Installation Details.
  • Switch to the tab Configuration
  • Search for a line that starts with -vm. The line following it shows which Java binary is used.

Depending on the name and location of the used Java binary one can figure out if a JRE or a JDK is used:

  • If the path contains “jre” (e.g. as in C:Program FilesJavajre6binclientjvm.dll) it is a JRE
  • If the path contains “jdk” (e.g. as in C:Program FilesJavajdk1.6.0_31binjavaw.exe) it is a JDK.

If no JDK is used for Eclipse, change it:

  • Quit Eclipse if it is running
  • Go to the Eclipse installation directory and open the file eclipse.ini in a text editor.
  • Search for the line -vmargs
  • Before the line -vmargs, add two lines:

    On the first line, write -vm

    On the second line, write the path to your JDK installation (usually something like: C:Program FilesJavajdk1.6.0_31binjavaw.exe on Windows)

2. Process To Set Environment Variable In Java

What is java environment variable?

Environment variable is a global system variable accessible by all the processes running under the OS.

Why Environment variable path set is required?

If you are saving the Java source file inside the JDK/bin directory, the path is not required to be set because all the tools will be available in the current directory. However, if you have your Java file outside the JDK/bin folder, it is necessary to set the path of JDK. PATH stores a list of directories for searching executable programs.
