This tutorial provides information about setting up an environment to use Solaris OS for developing Java ME application using BrandZ (Branded Zones), J2ME Wireless Toolkit 2.2 and Netbeans Mobility Pack 5.5. Branded Zones allow Linux applications to run on Solaris unmodified.
More information about the technologies used in this tutorial are available on following pages:
Also make sure that BrandZ is installed on your version of Solaris. If you are using Solaris Express Developers Edition, BrandZ is included in the default installation. Other versions of Solaris may need additional steps to install BrandZ.
Step-by-step guide to setting up our Branded Zone. The basic steps are as follows:
Pre-zone install configuration
Setting up networking in the global zone
This sets up a private network that is used to link the global zone with the branded zone you created. The Linux branded zone will not have external network access. If you want the Linux zone to have access to the external network you need to assign a valid IP address to the branded zone. However once the network goes away, so will access to your branded zone via ssh. This limitation can be worked around, but it is more complex (see here for more info). If you assign a real IP address to the branded zone you can skip this section (also substitute the real IP address for 10.10.10.3 in the following sections).
You can substitute username with any existing unix username you like.
I have an Intel Ethernet card and my network device is iprb0. To found out what network device you are using run the command:
[root@global_zone /]# /sbin/dladm show-link
Use this name in place of iprb0 in the following sections.
[root@global_zone /]# echo "addif 10.10.10.2 up" >> /etc/hostname.iprb0 [root@global_zone /]# echo "10.10.10.2 lhost" >> /etc/hosts [root@global_zone /]# echo "10.10.10.3 centos" >> /etc/hosts [root@global_zone /]# svcadm restart milestone/network
Branded zone installation
Make sure that you have enough disk space to install the zone, you'll probably need about 1.5GB. In the example I install into /data/brands/centos which resides on a ZFS filesystem. You can install the zone wherever you like. If you are using ZFS a filesystem is automatically created for you. Otherwise you may have to create the directory before creating the zone.
During zone configuration a filesystem is added to the branded zone. This filesystem is the home directory of the user mounted loopback into the zone. You should make sure that /export/home/username is the directory where the filesystem is mounted in the global zone. Create the zone
[root@global_zone /]# zonecfg -z centos centos: No such zone configured Use 'create' to begin configuring a new zone. zonecfg:centos> create -t SUNWlx zonecfg:centos> set zonepath=/data/brands/centos zonecfg:centos> set autoboot=true zonecfg:centos> add net zonecfg:centos:net> set address=10.10.10.3/29 zonecfg:centos:net> set physical=iprb0 zonecfg:centos:net> end zonecfg:centos> add attr zonecfg:centos:attr> set name="audio" zonecfg:centos:attr> set type=boolean zonecfg:centos:attr> set value=true zonecfg:centos:attr> end zonecfg:centos> add fs zonecfg:centos:fs> set dir=/home/username zonecfg:centos:fs> set special=/export/home/username zonecfg:centos:fs> set type=lofs zonecfg:centos:fs> end zonecfg:centos> commit zonecfg:centos> exit [root@global_zone /]#
Install the zone
Download centos_fs_image.tar.bz2 from the brandz webpage. I downloaded it to ~/Desktop/.
[root@global_zone /]# zoneadm -z centos install -d /home/username/Desktop/centos_fs_image.tar.bz2 A ZFS file system has been created for this zone. Installing zone 'centos' at root directory '/data/brands/centos' from archive '/home/username/Desktop/centos_fs_image.tar.bz2' This process may take several minutes. Setting up the initial lx brand environment. System configuration modifications complete. Setting up the initial lx brand environment. System configuration modifications complete. Installation of zone 'centos' completed successfully. Details saved to log file: "/data/brands/centos/root/var/log/centos.install.861.log" [root@global_zone /]#
Set the root prompt for the Linux zone
This step is unnecessary but I added it so that it obvious in the following instructions where the commands are being run and by whom.
[root@global_zone /]# cat > /data/brands/centos/root/root/.bash_profile <<EOF > export PS1="[\u@\h \w]# " > EOF [root@global_zone /]#
Boot the zone
[root@global_zone /]# zoneadm -z centos boot
Login and setup
In this section a new user is set up with the same uid as the user in the global zone. In order to determine the uid of the local user run the command:
[username@global_zone ~]$ id 4. Update opensolaris webpage. [done] [root@global_zone /]# zlogin centos [Connected to zone 'centos' pts/6] Welcome to your shiny new Linux zone. - The root password is 'root'. Please change it immediately. - To enable networking goodness, see /etc/sysconfig/network.example. - This message is in /etc/motd. Feel free to change it. For anything more complicated, see: You have mail. [root@centos ~]# useradd -u uid -M -d /home/username username [root@centos ~]# passwd username Changing password for user username. New UNIX password: Retype new UNIX password: passwd: all authentication tokens updated successfully. [root@centos ~]# printf '10.10.10.3 centos\n' >> /etc/hosts [root@centos ~]# printf 'NETWORKING="yes"\n' > /etc/sysconfig/network [root@centos ~]# printf 'HOSTNAME=centos\n' >> /etc/sysconfig/network [root@centos ~]# cat /etc/hosts [root@centos ~]# init 6 [root@centos ~]#
Set up ssh keys
ssh is used to provide seamless access to the zone, as it provides X forwarding X applications can be run easily. By using keys a password is no longer required to access the zone. The passphrase was left blank in the example below. (A passphrase can be used but it makes things slightly more complicated - see ssh-agent(1)).
[username@global_zone ~]$ ssh-keygen -t rsa Generating public/private rsa key pair. Enter file in which to save the key (/home/username/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/username/.ssh/id_rsa. Your public key has been saved in /home/username/.ssh/id_rsa.pub. The key fingerprint is: 32:f8:1c:e6:c1:ab:90:11:21:55:88:9d:94:d7:e6:c2 username@global_zone [username@global_zone ~]$ cp .ssh/id_rsa.pub .ssh/authorized_keys [username@global_zone ~]$
Set up the lrun script
[username@global_zone ~]$ cat > lrun > #!/bin/ksh > exec ssh -X centos "$@" > EOF [username@global_zone ~]$ chmod +x lrun [username@global_zone ~]$ mkdir ~/bin [username@global_zone ~]$ mv lrun ~/bin [username@global_zone ~]$ export PATH=$PATH:/home/username/bin
You may want to add "PATH=$PATH:/home/username/bin" to your shell rc file. Install Netbeans in the branded zone
[username@global_zone ~]$ chmod +x ~/Desktop/jdk-6-nb-5_5-linux.bin [username@global_zone ~]$ lrun ~/Desktop/jdk-1_5_0_10-nb-5_5-linux.bin The authenticity of host 'centos (10.10.10.2)' can't be established. RSA key fingerprint is be:49:a8:09:8c:19:18:cc:f2:1c:e3:84:c7:76:d7:5d. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added 'centos,10.10.10.2' (RSA) to the list of known hosts.
Install Netbeans Mobility Pack and Wirless Toolkit
To install NetBeans Mobility Pack 5.5 type:
[username@global_zone ~]$ lrun JAVA_HOME=~/jdk1.6.0 ~/Desktop/netbeans-mobility-5_5-linux.bin ...
Answer all the questions as usual, choose the default location to install.
(Optional, some version of Mobility Pack comes with Wirless Toolkit) There is two possible ways how to install Wireless Toolkit:
1) Using command line
[username@global_zone ~]$ lrun JAVA_HOME=~/jdk1.6.0 ~/j2me_wireless_toolkit-2_2-linux-i386.bin ...
2) Using Netbeans Update Center Answer all the questions as usual, choose the default location to install. If your branded zone has access to the internet it is possible to install some version of WTK directly from IDE using Netbeans Update Center.
Entry/Inline Property Editor
After installation don't forget to add new Java Micro Edition Platform Emulator using Java Platform Manager (menu: Tools>Java Platform Manager)
You can find more information about how to use Mobility Pack and add new Java Micro Edition Platform Emulator reading this tutorial:
[username@global_zone ~]$ sed -e 's#Exec=.*#Exec=lrun ~/netbeans-5.5/bin/netbeans#' ~/Desktop/netbeans5.5.desktop > /tmp/netbeans5.5.desktop [username@global_zone ~]$ mv /tmp/netbeans5.5.desktop ~/Desktop/netbeans5.5.desktop
Double-click on the NetBeans icon on your desktop to launch NetBeans! Any linux program in your home directory can be run as follows:
[username@global_zone ~]$ lrun <linux_program>
