(I think this is extremely important when documenting something that is likely to change within a year or so)

This document has a lot of common with Debian_and_PostgreSQL_Install as Ubuntu and Debian have a lot of common too :)

Common problems and their solution is described here: InstallServer

Let's assume you have Ubuntu 8.04 installed (32 bit for now).

sudo apt-get install sun-java6-jdk postgresql-8.3 postgresql-server-dev-8.3 wget

This will most likely install some other packages as well (enter root password for sudo, say yes).

Let's check this:

gabriel@erpdev:~$ dpkg -l|grep postgres
ii  postgresql-8.3                        8.3.3-0ubuntu0.8.04         object-relational SQL database, version 8.3

Okay, now something harder:

cd /tmp
tar zxf pljava-src-1.4.0.tar.gz 
cd pljava-1.4.0/

Hm, this will give us a lot of errors. We need jdk-5 to do the compile.

sudo apt-get install sun-java5-jdk

Java 5 is installed as well. Now test which java is used?

java -version

No good, Java6 is still used.

sudo update-alternatives --config javac

Now choose Java 5.

sudo update-alternatives --config java

Now choose Java 5 again.

Test again:

java -version

Hah! Java 5 is used. Good! Go back and retry:

cd pljava-1.4.0/

Almost okay, complaining about JAVA_HOME Now set JAVA_HOME:

export JAVA_HOME=/usr/lib/jvm/java-1.5.0-sun

Try again:


Oh yeah, compiling! (Ok, sorry, I've assumed you have gcc,make and maybe some other packages already installed). Complete package list: Ubuntu804PackageList

Under directory build you have pljava.jar, deploy.jar, examples.jar

Now let's install pljava libraries:

sudo su - 

You are root from now, so take care!

Edit /etc/hosts and change the entry of your machine name ( in my case) to something like this: erpdev

Create a file named /etc/ and add the following:

for i386


or for AMD64


Run ldconfig

ldconfig -v|grep jvm

If you see libjvm, then it's all right. Don't bother about lib64 ... :)

export JAVA_HOME=/usr/lib/jvm/java-1.5.0-sun
cd /tmp/pljava-1.4.0/
make install 

Edit /etc/postgresql/8.3/main/postgresql.conf and add at the end:

custom_variable_classes = 'pljava'
pljava.statement_cache_size = 10
pljava.release_lingering_savepoints = true
pljava.vmoptions = ' '
pljava.debug = false

Edit /etc/postgresql/8.3/main/postgresql.conf and look for "listen_addresses". Change to:

listen_addresses = '*'          # what IP address(es) to listen on;

If you would like to speed up database performance, you may search in this file for the word fsync, and change it to off (do not forget to uncomment, default is on). This is not recommended for production use, change it back later!

Edit /etc/postgresql/8.3/main/environment and add at the end:

JAVA_HOME = '/usr/lib/jvm/java-1.5.0-sun'

Edit /etc/postgresql/8.3/main/pg_hba.conf and add at the end:

host    all         postgres        md5
host    all         adempiere        md5

(of course replace the given IP and netmask with your own.

Restart postgresql:

/etc/init.d/postgresql restart

Now you should exit from the root shell:


Now let's install the SQL parts into the database. Please note that you have to install PLJava's SQL part into every database where you would like to use it! Of course if you install it into template1 then every database what you create afterwards will contain PLJava as well.

cd /tmp/pljava-1.4.0/src/sql

Become postgres user and then run psql

su - postgres

We are in psql, now connect to template1:

\c template1 

Now run install :

\i install.sql

Alternatively you can use the provided deploy.jar, although then you will have to copy the PostgreSQL JDBC driver into build directory.

You can check if the schema was created by


in psql. If sqlj is there, then you are all set.

Exit psql


Create user adempiere in the database

createuser -P adempiere
Shall the new role be a superuser? (y/n) n
Shall the new role be allowed to create databases? (y/n) n
Shall the new role be allowed to create more new roles? (y/n) n

(remember the password you give to adempiere user)

createdb adempiere -O adempiere 

Now you have the adempiere user and the adempiere database there with pljava installed and ready to be populated.

Now we need to change the password of the postgres user in the database, it's for 'DB Admin Password' of

psql --command "ALTER USER postgres PASSWORD '<system_password>'"

Exit postgres user and root user (most likely become adempiere (Unix) user again).

... unzip Adempiere ... InstallServer ... unzip database ... import database, check logs ... start Adempiere ... add init script
