SJSAS 7 working on Linux (Kernel 2.6.x)

Installing (and
hacking) Sun Java System Application Server 7 on Linux

Preface

    Sun Java System Application Server 7 is the J2EE 1.3

Application Server from Sun Microsystems. The supported Linux operating

system is RedHat Enterprise Linux 2.1 and 3.0. Any other Linux

operating system is not supported, but that

doesn’t stop anyone to install Sun Java System Application Server 7 on

any Linux distribution, but that doesn’t have any warranty nor

endorsement from Sun. I will call Sun Java System Application Server 7

of SJSAS7 to make it easy.

    SJSAS7 can be installed on any Linux distribution,

which has Kernel 2.4.x, I did that on Mandrake Linux 9.2. But for a

unknown reason, the SJSAS7 Installation process doesn’t work on Linux

Kernel 2.6.x.

    My system is a Mandrake Linux Official 10.1 and a

custom kernel 2.6.10 with patches, so my system is an unsupported one.

I was tired to switch to windows, just to run SJSAS 7, and it is

supposed to be entirely implemented in Java (but Sun WebServer is not

Java), then I just need to try to do a hack and make it work on linux.

After 6 hours it is done.

Requirements

– Sun Java System Application Server 7 for linux: sunappserver7.tar.gz

  I used SJSAS 7 2004Q2 Update 1

  http://www.sun.com/download/index.jsp?cat=Application%20%26%20Integration%20Services&tab=3&subcat=Application%20Servers

– An already installed SJSAS 7, preferably on linux

  I used a sparc installation

  I will call it SJSAS7-REF, that will serve as reference of

configuration for the linux instance

– A running JVM 1.4.2 or greater

  If you don’t want to install the SJSAS7 bundled JDK

  eg: /opt/j2sdk1.4.2_06

Installation

• Make a backup of some directories of SJSAS7-REF
• SJSAS7-REF/config

• SJSAS7-REF/bin

• Untar the downloaded SJSAS7, eg:

  UNTAR=/home/claudio/sunappserver-7

• Create the directory to install SJSAS 7, eg:

  /opt/sjsas7-2004Q2-up1

  I will call it: SJSAS7

• cd /opt/sjsas7-2004Q2-up1

• unzip $UNTAR/packages/*.zip
• exceptions:
• If you don’t want to install a new JDK, don’t unzip jdk.zip
• if you don’t want pointbase, don’t unzip SUNWasdbo.zip
• $UNTAR/packages/ant.zip

• $UNTAR/packages/perl.zip

• Some files is duplicated across some zip files, you can replace

  them safely.

• ANT installation
• mkdir lib/ant
• cd lib/ant

• unzip $UNTAR/packages/ant.zip

• Perl Installation
• mkdir lib/perl
• cd lib/perl

• unzip $UNTAR/packages/perl.zip

• copy $SJSAS7-REF/bin to $SJSAS7/bin
• copy $SJSAS7-REF/config to $SJSAS7/config
• mkdir $SJSAS7/domains

Configuration

Some adjustments on configuration files needs to be done for the newly

linux installment.

What needs to be adjusted:

• J2SE SDK location
• SJSAS 7 home location

• Native JVM lib (if the SJSAS7-REF is solaris)

• cd $SJSAS7/bin

• Each script file, at the beginning has the full path of the

  asenv.conf file, adjust it to reflect your installment

  eg: .
  /opt/sjsas7-2004Q2-up1/config/asenv.conf

You can use the following command:</p>

find . | xargs perl -i.bkp -p -e
‘s/\/opt\/sjsas7-ref/\/opt\/sjsas7-2004Q2-up1/g;’

Where:

• -i: do a backup of each file
• -e: runs the specified regular expression
• -p: reads each line of the file

• cd ../config

• Edit asenv.conf, adjust the directory to reflect your

  environment

• SJSAS7 home, eg: /opt/sjsas7-2004Q2-up1

• JDK_HOME

• The $SJSAS7/config/domains.bin file needs to be reflect the

  current environment

• run asadmin list-domains, that will show the domain list, eg:

  /sunappserver7/domains/domain1

  /sunappserver7/domains/test

• And the SJSAS7 is located under /opt/sjsas7-2004Q2-up1, the

  domains need to be under this directory

• create the following directories

  /sunappserver7/domains/domain1

  /sunappserver7/domains/test

• run asadmin delete-domain domain1 and delete-domain test
• remove the /sunappserver7 directory
• create new domain and instance

• asadmin create-domain –path 

  /ope/sjsas7-2004Q2-up1/domains/ –adminport 4881 –adminuser admin

  –adminpassword admin123 domain1

Final Notes

• Do a search on the SJSAS7 home

• grep -Hr $SJSAS7

  eg: grep -Hr SUNWappserver /opt/sjsas7-2004Q2-up1

  eg: grep -Hr

  /opt/sjsas7-2004Q2-up1

• Do a admin-server test

  cd $SJSAS7/domains//admin-server/bin

  ./startserv -configtest

• Deploy some sample application to test the instance.

Conclusion

If everything were done right, the
admin-server can be started. Check the logs for any failure.</p>

The user and password for admin-server are the same as SJSAS7-REF, be
aware.

After logged in, instances can be created through admin server (web
interface or asadmin console)
