Unsign, resign and update .JAR manfests

Posted by on May 15, 2013 Comments Off on Unsign, resign and update .JAR manfests

A .jar file is simply a .zip with a funky extension. Rename the .jar to .zip and unzip the file.

CD into the META-INF dir and delete everything EXCEPT the manifest file.

Edit the Manifest file and remove all the SHA hashes (probably not necessary)

Once this has been done, rezip the file

zip -r yourjarfilename.jar *

Now we need to sign the jar. (Make sure you have the latest JDK installed)

To do this we create a key:

/usr/java/jdk1.7.0_21/bin/keytool -genkey -alias xenvncviewer -validity 365

Follow the bouncing ball filling in all the details.

Then sign your JAR file with the following:

/usr/java/jdk1.7.0_21/bin/jarsigner xenvncviewer.jar xenvncviewer

That is it!

we need to fdisk the partition of the second drive with:

pfexec fdisk -B c13t1d1s0

Copy label from the original rpool member

pfexec prtvtoc /dev/rdsk/c13t1d0s0 | pfexec fmthard -s - /dev/rdsk/c13t1d1s0

Attach mirror drive to the pool

zpool attach -f rpool c13t1d0s0 c13t1d1s0

Install grub on the second drive.

installgrub /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c13t1d1s0
