Red linux上装J2EE环境

[harryzyp]

JDK1.4 Tomcat5.0 已经装上了,在/usr/profile文件中设置环境变量如下:
set JAVA_HOME=/usr/java/j2sdk1.4.2_13
set CATALINA_HOME=/usr/jakarta-tomcat-5.0.28
set PATH=$JAVA_HOME/bin;$PATH
set CLASSPATH=.;/usr/java/j2sdk1.4.2_13/lib/dt.jar;/usr/java/j2sdk1.4.2_13/lib/htmlconverter.jar;/usr/java/j2sdk1.4.2_13/lib/tools.jar

export JAVA_HOME CATALINA_HOME PATH CLASSPATH

感觉环境变量设置确实没错啊,运行命令java正常,javac就出现错误bash: javac: command not found
另外运行/usr/jakarta-tomcat-5.0.28/bin/startup.sh,出现错误:
The JAVA_HOME environment variable is not defined
This environment variable is needed to run this program

哪里错了呢?

[singleon]

CLASSPATH=.;/usr/java/j2sdk1.4.2_13/lib/dt.jar;/usr/java/j2sdk1.4.2_13/lib/htmlconverter.jar;/usr/java/j2sdk1.4.2_13/lib/tools.jar
在linux里面要改成
CLASSPATH=.:/usr/java/j2sdk1.4.2_13/lib/dt.jar:/usr/java/j2sdk1.4.2_13/lib/htmlconverter.jar:/usr/java/j2sdk1.4.2_13/lib/tools.jar
;号改为:

[harryzyp]

你是说"分号"改成"冒号"吧?
我改了,而且这个分号也改了set PATH=$JAVA_HOME/bin;$PATH

但还是原来一样的错误

这是我以前帮别人写的请搂住大人参考

输入命令java -version

java version "1.3.1"
jdkgcj 0.2.3 (http://www.arklinux.org/projects/jdkgcj)
gcj (GCC) 3.2.2 20030222 (Red Hat Linux 3.2.2-5)

如果出现上面提示则说明你及其中已经安装了jdkgcj，这个程序会与SUN JDK冲突所以我吧他卸载了
用 jdkgcj命令查看具体的版本名称后执行下面命令卸载jdkgcj
rpm -e jdkgcj-0.2.3-5

为JDK修改环境变量文件

vi /etc/profile
进入编辑界面，再最后添加下列命令
#-------------------j2sdk-----------------------------
JAVA_HOME=/usr/java/j2sdk1.4.2_09
export JAVA_HOME
PATH=$PATH:$JAVA_HOME/bin
export PATH
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/jre/lib/rt.jar
export CLASSPATH
#-----------------------------------------------------

执行source /etc/profile 重新加载环境变量
输入java -version 如果出现下列提示则说明安装完成
java version "1.4.2_09"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_09-b05)
Java HotSpot(TM) Client VM (build 1.4.2_09-b05, mixed mode)

帮忙顶

[harryzyp]

我的输入java -version后出现如下信息:
java version "1.4.2"
gcj (GCC) 3.4.6 20060404 (Red Hat 3.4.6-3)

也没有sea_way(狒狒) 所说的jdkgcj 0.2.3 (http://www.arklinux.org/projects/jdkgcj)
况且如何查看jdkgcj的版本呢,用什么命令?

[littlegang]

似乎应该一个一个export，随便说的

set JAVA_HOME=/usr/java/j2sdk1.4.2_13
set CATALINA_HOME=/usr/jakarta-tomcat-5.0.28
export JAVA_HOME CATALINA_HOME
set PATH=$JAVA_HOME/bin;$PATH
set CLASSPATH=.;/usr/java/j2sdk1.4.2_13/lib/dt.jar;/usr/java/j2sdk1.4.2_13/lib/htmlconverter.jar;/usr/java/j2sdk1.4.2_13/lib/tools.jar

export PATH CLASSPATH

给你看下我的linux下的安装历史记录，相信可以对你有点帮助：
1 cd /
2 ls
3 cd /tools
4 ls
5 ls
6 chmod a+x j2sdk*
7 chmod a+x jdk*
8 ls
9 ls -a
10 ls -l
11 ./jdk*.bin
12 ls -l
13 chmod +x jdk*.rpm
14 ls -l
15 rpm -ivh jdk*.rpm
16 cd /usr/java/
17 ls
18 cd jdk
19 cd /jdk*
20 cd jdk*
21 ls
22 vi /etc/profile
23 vi /etc/profile
24 java -version

vi /etc/profile后就在最后加入：
export JAVA_HOME=/usr/java/jdk1.5.0_10
export PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin
export CLASSPATH=.:/usr/java/jdk1.5.0_10/lib:/usr/java/jdk1.5.0_10/jre/lib:$CLASSPATH

然后重新启动下！
再：
java -version
