Configure Java?

I need to switch the version of Java that I am using.

I found Ubuntu instructions for it:

sudo apt-get install ia32-sun-java6-bin

sudo update-alternatives --config java

Then choose the ia32 version of Java 6.

When I try to:

sudo pacman -S ia32-sun-java6-bin

and

sudo update-alternatives --config java

I get package not found and command not found.

How would I do this in Arch? Thanks for any help.

Re: Configure Java?

I can't help you with the version of Java that you're trying to install, but have you looked into IcedTea6 or OpenJDK7 for 64 bit (of course I'm assuming 64 bit). There was a bit of a discussion here about not only compiling it, but the links to the packages in the French-Arch repos:

Re: Configure Java?

You might also try the 32-bit version for x86_64 on AUR.  If you haven't used it before, get 'yaourt' from here first and use it to fetch/install all the pre-requisites for AUR packages - it makes life much, much easier.  I use the 32-bit installation because I still can't get the Iced-Tea version to run my Java web-start stuff that I need to run at work.

Good luck!

Re: Configure Java?

Thanks for the replies.

The 32-bit version of Java is exactly what I need. Or at least it solved the problem back when I used Ubuntu. It is a Frostwire problem that I am working on.

Yes I have yaourt, which is just excellent. I did a 'yaourt -S lib32-jdk' which seemed to be the proper package from the link that you posted. Things seemed to go smooth but at the end of the installation I get:

loading package data...
checking dependencies...
error: replacing packages with -A and -U is not supported yet
error: you can replace packages manually using -Rd and -U
error: failed to prepare transaction (conflicting dependencies)
:: lib32-jdk: conflicts with jre
==> WARNING: Your package is saved in /tmp/lib32-jdk-6.0u5-1-x86_64.pkg.tar.gz
If you like this package, please install aurvote
and vote for its inclusion/keeping in [community]

I am not experienced with Yaourt or AUR yet so I don't know if the package actually installed and if so did it replace the 64-bit Java as the default?

Re: Configure Java?

Okay, I used pacman to remove Frostwire and jre, then installed lib32-jdk with yaourt. It seemed to work fine this time, no errors. Then I used pacman to reinstall Frostwire.

Now when I attempt to start Frostwire I get:

Something went wrong with FrostWire.
Maybe you're using the wrong version of Java?
(FrostWire is tested against and works best with with Sun's JRE, Java 1.4+)
The version of Java in your PATH is:
./runFrostwire.sh: line 134: java: command not found

So I look into /usr/share/frostwire/runFrostwire.sh:

# install directory.

    echo 
fi

Line 134 is 'java -version' which I marked in the code, just here, not in the real file.

So what do I do to tell Frostwire to use the 32-bit Java?

Thanks for the help.

Re: Configure Java?

You probably need to run the command:

$ source /etc/profile

Your system probably is using the old environment location for Java instead of the new 32-bit version's location.  If you type 'which java' and it doesn't say '/opt/java32/bin/java', then your ENV isn't set up correctly.

Re: Configure Java?

Thanks for the reply. I did a 'source /etc/profile' and ran Frostwire. Here is what I got.

[theavataroftime@Imladris ~]$ frostwire

The version of Java in your PATH is:
java version "1.6.0_05"
Java(TM) SE Runtime Environment (build 1.6.0_05-b13)
Java HotSpot(TM) Server VM (build 10.0-b19, mixed mode)

It looks to me like Frostwire is looking in the wrong place for Java. But I really have no idea. Any ideas anyone? Thanks.

Re: Configure Java?

OK - now it looks like you're missing a 32-bit library.  I tried to catch them all when I made the package, but I guess I missed one.  From your error message, I'd guess you need to install 'lib32-libxp'.  When I look for it, I see:

$ pacman -Ss lib32-libxp
archlinuxfr/lib32-libxp 1.0.0-1
    X11 X Print Library

So you will want to add the archlinuxfr repository if you haven't already...

Good luck once again!

Re: Configure Java?

Thank you kindly, Frostwire is now working. However, it is going really, really, really, slow. Takes about five minutes to startup after the splash screen comes up. This is not an issue with my computer being slow. smile

I ran into the same problem with another 'fix' that I had found: http://bbs.archlinux.org/viewtopic.php? … 31#p373131

Where you saved a 'frostwire.sh' in the home folder and ran it with 'sh frostwire.sh'. It basically told Frostwire to get Java from another path, if I remember right. It made Frostwire work too, with the same five minute delay.

Any ideas as to how I would make Frostwire launch at a normal speed? Thanks.
