페도라 코어 3 에서 자바&이클립스 설치 관련 질문드립니다.

리눅스 입문자 입니다..
아직 갈길이 구만리 같네요..
어제 밤새해본 자바 설치때문에
질문드립니다.

다른곳에도 질문을 올렸는데 답을 찾을수 없어 이곳까지올립니다
이곳저곳올려 괜히 죄송스럽네요
인테넷의 메뉴얼대로 자바를 깔았습니다
그런데 , 이클립스가 실행이 안되네요..
그래서 클래스 패스를 잘 못 설정해서 그런가 해서 계속
만지고 있는데 잘 안됩니다..
이클립스를 실행하면 아래와같은 에러가 뜹니다.
JVM terminated. Exit code=1
/usr/bin/java
-cp/home/jangse/eclips/startup.jar
org.eclipse.core.launcher.Main
-os linux
-ws gtk
-arch x86
-showsplash/home/jangse/eclipse/eclipse- showsplash 600
-exitdata/home/jangse/eclipse/eclipse -exitdata 328011
-vm /usr/bin/java
-vmargs
-cp /home/jangse/eclipse/startup.jar
org.eclipse.core.launcher.Main

자바 설치는 아래와 같이 하였습니다.

]# chmod 755 j2sdk-1_4_2_06-linux-i586.bin

]#./j2sdk-1_4_2_06-linux-i586.bin

로 설치후

]# vi /etc/profile 실행..

JAVA_HOME=/usr/local/java
export JAVA_HOME
PATH=$PATH:$JAVA_HOME/bin

일게 하고 저장후

]# source /etc/profile

자바 설치 폴더는 java 라는 이름으로 하고 usr/local/java 로 두었습니다.

그런데 터미널에서 java 나 java -version
을 치면 아래와같은 경고같은 메세지가 뜨네요..
클래스 패스가 제대로 안잡혀 있는건가요?

This script is a placeholder for the /usr/bin/java
master link required by jpackage.org conventions. libgcj's
rmiregistry, rmic and jar tools are now slave symlinks to these
masters, and are managed by the alternatives(8) system.

This change was necessary because the rmiregistry, rmic and jar tools
installed by previous versions of libgcj conflicted with symlinks
installed by jpackage.org JVM packages.

위와같은경고메세지를 구글에서 찾아보니,

I had the same problem with Fedora Core 3, however it's not as simple as just doing rpm -e gcc-java. There where (or may be) other programs that depend on gcc-java, so you may need to track down which dependencies you have to resolve.

When I got a successful gcc-java uninstall I just rebooted the machine and voila, java for everyone and more for me ;)

By the way, don't forget to add your whole java sdk path to your /etc/profiles as root, so everyone can access java from the command line

이런글이 있는데요 , 영어는 못하지만 대충 읽어보니

gcc-java 의 패키지와 충돌한다는 내용인거같은데
gcc를 지우라는데. 이렇게 하면 해결점이 될지 궁금하네요
리눅스에서는 gcc가 없으면..ㅡㅡ;

또다시 구글링을하니

아래와 같은글을 찾을수있었습니다..

Java Fix for UBLinux 3.0
UBLinux 3 comes pre-loaded with Java SDK and RE. Unfortunately, due to a conflict with another package (libgcj), the java runtime environment (java) and the java compiler (javac) do not run correctly. Instead, when you try to execute either of these programs, it comes back with this message:

libgcj-java-placeholder.sh

This script is a placeholder for the /usr/bin/java and /usr/bin/javac
master links required by jpackage.org conventions. libgcj's
rmiregistry, rmic and jar tools are now slave symlinks to these
masters, and are managed by the alternatives(8) system.

This change was necessary because the rmiregistry, rmic and jar tools
installed by previous versions of libgcj conflicted with symlinks
installed by jpackage.org JVM packages.

This is a known issue with UBLinux 3.0, and will be fixed in later versions. Basically, the libgcj package is subverting default Java conventions. In order to fix this, we need to "undo" the changes the libgcj package made.

For UBLinux 3.0 users, we've created the sunjavafix RPM to do this for you. To install, download the file, open a terminal window, and with superuser privileges type:

rpm -i sunjavafix-ub-1-ub3.rpm

As always, if you have any questions regarding the UBLinux distribution, please feel free to contact us at ublinux-support@buffalo.edu. For general questions regarding using Java or Linux, contact the CIT Help Desk at cit-helpdesk@buffalo.edu.

libgcj 패키지 설정어쩌고 하면서 뭘 깔아라..하는데..
지금은 집이 아니라..아직 못하고 있구요. 있다가 한번 해봐야
할텐데 괜히 이상한거 까는건 아닌지..

아래와 같은 글도 찾았는데 이글또한 libgcj 에대한 언급이 있네요

I installed the java SDK RPM from java.sun.com.

Recently, however, I noticed that /usr/bin/java, /usr/bin/javac, and
/usr/bin/jar point to scripts in /etc/alternatives.

I figured out that these replacements are from libgcj. It doesn't look
like I can until this other RPM as there are others that depend on it.
My question is why do they replace a legitimate program (java) with a
script that doesn't do anything. That just seems to break everything.
I remove the link so the real java program is picked up correctly. Does
anyone know what this is for and why its done?

혹시 원인을 아시는 분들은 ...답변 부탁 드립니다
긴글 읽어주셔서 감사합니다.
