Open Source Java all the way


I am really pleased to see that the IcedTea project doing so well that for all the sites that need Java enabled in the browser, icedtea is more than sufficient.  It used to be the case that I needed to download from java.com the RPMs for my installations before I could get access to http://www.dbs.com, http://www.cpf.gov.sg and more importantly, for my sons, http://www.runescape.com.

I’ve just moved to the latest Fedora 15 on my Dell Vostro V13 laptop and my well-worn practise, check that I could get access to DBS, CPF and runescape. And they all worked.

How does one know if Java is installed on the machine?

Start the browser (Firefox or chromium), type in “about:plugins” in the URL section.  On Chromium, you will see among other plug-ins, a section that says:

IcedTea-Web Plugin (using IcedTea-Web 1.0.2 (fedora-2.fc15-x86_64))

The IcedTea-Web Plugin executes Java applets.

If that section does not show up, you do not have Java enabled for the browser. In which case, in Fedora, for example, you can choose the Add/Remove Software option, search for icedtea and install it. Once the icedtea is installed, you should restart your browser in order for the browser to pick up the new plug-in. That’s it. Open source Java FTW!
