How to create IPS packages for OpenSolaris

Creating IPS packages for Opensolaris consists of four important steps :

1. Building the package using common method like, make, make install and figure out the dependencies.
2. We need to have a build environment (CBE) [ one time step ]
3. We need to write a spec file
4. We will use pkgtool to generate IPS
5. Building the environment for development

Prerequisites:

Install sunstudio compiler using the command

pfexec pkg install ss-dev

Install the following required packages similarly

• SUNWgnome-common-devel
• SUNWperl-xml-parser
• SUNWgnome-xml-root
• SUNWgnome-xml
• SUNWgnome-xml-share
• SUNWdoxygen (optional)

Installing the Common Build Environment

Download the CBE(Common Build Environment) from :

http://dlc.sun.com/osol/jds/downloads/cbe/test/

Ensure you select the correct architecture. Once downloaded, extract the contents from the tarball. To install run cbe-install. This needs to be run by a user with Primary Administrator privileges. Users wishing to run and CBE once installed successfully should have at least Software Installation privileges. Privilages are easy enough to add, by either manually editing the /etc/user_attr file or using usermod(1) with the -P CLI option.

Download latest pkgbuild from here :

http://pkgbuild.sourceforge.net/download.php (version >= 1.3.98, for generating IPS packages)

CBE 1.7+ includes a version of pkgbuild which at the moment does not generate IPS packages. If you just want to compile packages and generate SVR4 packages then there is no need to perform this step. Use the installed CBE to build the downloaded latest pkgbuild package

$ cd pkgbuild-1.3.98

$ ./configure –prefix=/opt/dtbld/

$ make

$ pfexec make install Set the build environment

$ . /opt/dtbld/bin/env.sh

Get existing spec files to play around with: svn co svn+ssh://anon@svn.opensolaris.org/svn/jds/spec-files/trunk spec-files-trunk

set the build environment by sunning the following script.
$ . /opt/dtbld/bin/env.sh

Building the package and Generating IPS

pkgtool –download –ips build-only SFEjoe.spec

 

Before executing the above command the local repository must be setup to run at localhost:80 using

svcadm enable pkg/server

 

for IPS repo on http://localhost:80 )

How to open a .war (web archive) or .jar (java archive) files

With Java we generate .JAR files to bundle a set of resources. For J2EE web applications, we generate .WAR (Web Archive) files for deployments. Both of these are ways of archiving a set of files.

Both these .jar or .war archives are in zip format. So there are plenty of ways to open those files to read the content. One way would be to use any tool that you use to open/extract a .zip file. Next will be to use the Jar command itself.

JAR Command

JAR (command) utility in Java can be used to open/extract these files as follows. Run following command from the folder where you need the content to be extracted by providing the path to the archive.

jar xf

options:

x – extract the files
f – file to extract

jar xf myWebApp.war
jar xf myProject.jar
