wget -c http://www.java.net/download/jdk7u2/archive/b05/binaries/jre-7u2-ea-bin-b05-linux-x64-31_aug_2011.tar.gz

tar zxvf jre-7u2-ea-bin-b05-linux-x64-31_aug_2011.tar.gz -C /usr/local

update-alternatives --install /usr/bin/java java /usr/local/jre1.7.0_02/bin/java 1 --slave /usr/local/man/man1/java.1 java.1 /usr/local/jre1.7.0_02/man/man1/java.1

update-alternatives --config java

When I select jre1.7.0_02 i get this:

update-alternatives: error: unable to make /usr/local/man/man1/java.1.dpkg-tmp a symlink to /etc/alternatives/java.1: No such file or directory

 
I think i screwed up the --slave, should it be: --slave /etc/alternatives/java.1 java.1 /usr/local/jre1.7.0_02/man/man1/java.1  or  --slave /etc/alternatives/java.1 java.1 /etc/alternatives/java.1   or something else ?
