Set JAVA environment variable path
 

how to set java and ant environment variable path or can any one tell me how to set the path of tools.jar?

Here is how to set the path for Java. Suppose you have JDK installed in /opt.
Then add the following lines to .bashrc

export JAVA_HOME=/opt/jdk1.6.0_32
PATH=.:$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH

cd /opt/prod/java/jdk-6u24-linux-i586.bin


Install jdk file

./jdk-6u24-linux-i586.bin


Configure
#alternatives --install /usr/bin/java java /opt/prod/java/jdk1.6.0_24/bin/java 1

#alternatives --config java -Select installed java path java path

#java -version --> Check whether java path is enabled

$ vi ~/.bash_profile

export JAVA_HOME=/opt/prod/java/jdk1.6.0_24/bin/java


export PATH=$PATH:/opt/prod/java/jdk1.6.0_24/bin/java


To view Java_HOME path

$ echo $JAVA_HOME
$ echo $PATH
