JAVA_HOME defined but maven2 compains it could not find it

/usr/lib/jvm/java-6-sun-1.6.0.20/bin
is the directory where my Java resides.
in the .bashrc have following

Code:

JAVA_HOME="/usr/lib/jvm/java-6-sun-1.6.0.20/bin"
export JAVA_HOME

/etc/environment and /etc/profile
have the default entries no changes with them.

Code:

 echo $JAVA_HOME
/usr/lib/jvm/java-6-sun-1.6.0.20/bin

then Installed

Code:

aptitude install maven2

when I run mvn get error

Code:

Error: JAVA_HOME is not defined correctly.
  We cannot execute /usr/lib/jvm/java-6-sun-1.6.0.20/bin/bin/java

I am not having any clue as what is this error?
As to me JAVA_HOME seems to be defined.

If you look at the error, you've got this:

Quote:

/bin/bin/java

Usually JAVA_HOME is defined as the root of the java tree, not the bin directory, so if you re-define it in .bashrc as

JAVA_HOME="/usr/lib/jvm/java-6-sun-1.6.0.20

it will probably work.

The error tells you that JAVA_HOME is not defined correctly. It looks like you need to get rid of "bin" at the end..

Ok removing the bin seems to work.
I got rid of the error
but
Also worth mentioning

Code:

which java
/usr/bin/java

is not pointing to JAVA_HOME/bin/java

Have you looked to see if /usr/bin/java is a symlink to the JAVA_HOME/bin/java?

Ok I manually did that.
