yeah... that is what I do... but if I coiuld do it system wide then I could get applications such as JBoss to work with the system wide JDK. Also, I could then use standard rpm like Ant that are provided by SuSE whithout having to worry about which java version is being used. My only wish list for 10.1 is to have an easy standard way to replace the jdk without breaking stuff. Currently, 10.1 uses the alternative mechanism.... so... what are the steps to use the alternative mechanism to install a JDK? -H On 3/22/06, Claes at work wrote:

My recommendation is to install the jdk somewhere in your home directory, set JAVA_HOME to point it and add $JAVA_HOME/bin to your PATH

Hi

What is the proper procedure to replace the java implementation supplied with 10.1-b8 with Sun java? If possible I would like to use the alternative mechanism. I am a newbie with the alternative mechanism.

thanks in advance.

Hi

I am a newbie with the alternative mechanism. I don't know if the beta comes with a Sun Java package, but the ones from 10.0 should work fine if it doesn't. You will need jpackage-utils as well.

The proper way to changed java/javac is by using update-alternatives --config java and update-alternatives --config javac

I will try changing using alternatives as you suggest.

The problem with the the Java supplied from 10.0 is that Java 1.5 is a JRE which can be used to run Java but NOT for developeing in Java. In

Err.. why? $ rpm -ql java-1_5_0-sun-devel|grep -w javac /usr/lib64/jvm/java-1.5.0-sun-1.5.0_06/bin/javac /usr/share/man/man1/javac-java-1_5_0-sun.1.gz The java-1_5_0-sun-devel package has the javac compiler. It's the same scheme for 1.4.2 and 1.5.0: - - java-VERSION-sun: that's the JRE - - java-VERSION-sun-devel: that's the javac compiler and JNI - - java-VERSION-sun-alsa: ALSA support for the Java Sound API - - java-VERSION-sun-plugin: the Java plugin for browsers (and a few more: -demo, -jdbc, -src) (and where "VERSION" is either "1_4_2" or "1_5_0") Why do you say that Java 5 supplied on SUSE 10.0 is only the JRE ?

essense all Java developers have to hack 10.0 and are always having to resolve conflicts in the system. I am hoping 10.1 does provide a mechamism to change the Java settings.

I really don't see what you mean. Works very well here on 10.0, I have both 1_4_2 and 1_5_0 installed, and I compile quite a lot of Java code (and Eclipse, and JBoss, and Tomcat, and Spring, ...). cheers - -- -o) Pascal Bleser http://linux01.gwdg.de/~pbleser/ /\\ _\_v The more things change, the more they stay insane. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (GNU/Linux) iD8DBQFEJG+Pr3NMWliFcXcRAqU0AKCdzQPJqAHUNaNRJmega+320HZylQCeKyID 8lfXiq1XkVBiv7hSUdinT7c= =SWaO -----END PGP SIGNATURE-----
