2.4.1 Installing a JVM

2.4.1 Installing a JVM

If Eclipse did not start correctly, your system may not have a JVM. Go to http://java.com/en and click the Free Java Download button. Java offers two different mechanisms for installation under Windows — online and offline. Clicking the link Windows XP/Vista/2000/2003 Online downloads a small (360 KB) executable, jre6u3-windows-i586-p-iftw.exe. This program in turn installs the rest of the JVM from the web.

You are given the opportunity to view, and then either to accept or to decline the terms of the Java license. Assuming you accept, the installation proceeds without any further user input required.

Alternatively, you can click Windows XP/Vista/2000/2003 Offline, which downloads a much larger (about 13.8 MB) executable, jre-6u3-rc-windows-i586.exe. This is the entire JVM package. The offline installation offers additional options—the Google toolbar and desktop—and more control over the installation process. A custom setup screen allows you to select the options to be installed. Unless you’re an “advanced” user, it’s probably best to accept the defaults.

Following installation, restart your browser and go back to http://java.com/en/. Select the Advanced tab and click the link Do I have Java? to bring up the Verify Installation page. Click the Verify Installation button. This should confirm that the JVM is properly installed. If not, you may need to configure the JVM.

Open the Windows Control Panel and double-click the Java icon (the coffee cup). Select the Advanced tab and click on the + next to Default Java for browsers. Check all the boxes on that branch to enable Java for the web browsers on your system.
