how to remove specific pattern from a line using shell script

[ram.sj]

Hi,

In javapath.txt file, I have a line like this,
JAVA_PATH=`locate /bin/javac | grep 1.6.0 | awk '{if (NR==1) {print}}' `
echo "$JAVA_PATH"

I want to set JAVA_HOME from this JAVA_PATH.
JAVA_PATH is like /usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0.x86_64/bin/javac
I am print this into a file like,
echo "JAVA_HOME=$JAVA_PATH" > javahome.sh

For JAVA_HOME, I need to give upto /usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0.x86_64

How can specifically remove /bin/javac from the file javahome.sh
please help me on this.

Thank you,

Arun
