If you had actually clicked on the homepage link in the emerge -s output you posted, you would have seen in the very first bullet point right at the start of the page that icedtea-web is mostly Java Web Start > (ii) Why the version jump from 1.10.4 to 6.1.10.4? Look carefully. It's not a version jump, just the addition of a 6. prefix. It's to bring the -bin package version into line with the source code version > (iii) Why is the -bin one major version behind icedtee? No idea. You should ask the builder of the bin packages.

Do you need to have so many different browsers on your computer? How about editors? Or for that matter why do you have so many coding languages available? How about openoffice? It's not "so many", that's a ridiculous assertion. First you have a choice between iced-tea built from source or a bin package. Firefox and OOo do the same. Then there's icedtea-web which is a whole different package altogether, implementing Java Web Start (which is not the java language, the sdk or a jvm). So, if you want Java as implemented by iced-tea, pick between source and -bin. If you want JWS, then emerge that too. Did you even attempt to google this and find answers yourself? -- Alan McKinnnon alan.mckin...@gmail.com
