lenny java 安装设置问题

tigatron

源里面自带 eclipse 啊，装了之后肯定可用（这时你再自己装另外版本的 eclipse 也应该不会出什么问题）

ak_birdofprey

就是用源里的安装的，我的装完之后启动也报楼主那样的信息。不知道为什么。请解决了的共享下解决方法哦

不好意思由于最近一直在忙考试，所以好久没有上论坛了，
我是这么解决的，首先到sun下载最新的JDK;解压后整个文件夹移到/opt中，下一步设置环境变量，
su root
gedit /etc/profile在export PATH前加入以下几行；

JAVA_HOME=/opt/jdk1.6.0_12
PATH=$JAVA_HOME/binPATH
CLASSPATH=.JAVA_HOME/lib/dt.jar:JAVA_HOME/lib/tools.jar
export JAVA_HOME,PATH,CLASSPATH

此处 /opt/jdk1.6.0_12为我的JDK存放的路径
至于ecplise我也到官网下的压缩包，是直接解压到/opt下直接双击就能运行了；
真的非常抱歉，到现在才回复，大家多多交流，共同学习

我是这么干的
找到/usr/bin/下的eclipse文件，发现是个sh脚本有这样的东东之前是注释掉的或不完整
export JAVA_HOME
export CLASSPATH
这两句去掉注释，补充完整
export JAVA_HOME=/xxx/jdk1.5.0_12/
export CLASSPATH=/xxx/jdk1.5.0_12/jre/lib
双击该脚本，就可以运行了
后来我下了个eclipse3.4，又安装了jdk1.6发现可以这样
写一个sh脚本内容如下
eclipse -vm /xx/xx/jdk1.6.0_13/jre/bin/java
也可以，记得给脚本运行权限，eclipse目录、工作目录也要chmod一下
chmod -R 777 eclipse
chmod -R 777 /xx/yy/workspace/

告诉eclipse你的jre在哪里就可以了

啊，刚才仔细看了一下chenming2065151的方法，貌似我当时是这样弄的，就是不灵
后来才摸索出上贴的方法
难道当时敲错字母了？？！！

使用vi /usr/bin/eclipse.将所有的MOZILLA_FIVE_HOME=之后的内容注释掉。然后加入：export MOZILLA_FIVE_HOME="",就可以了。我的/usr/bin/eclipse如下：
#!/bin/bash

# Having any sort of classpath causes massive breakage, with Kaffe at least.
unset CLASSPATH; export CLASSPATH

# Allow the user to specify their own Java home, we check for it later.
#unset JAVA_HOME; export JAVA_HOME

恩，和windows下一样，把环境变量设置好，这样在文本模式下也能编译运行java了
