GitHub Setup

  1. Fork Repo into your github account

  2. Run on your local machine:

     git clone<github-username>/jentrata-msh.git
     cd jentrata-msh.git
     git remote add upstream

You can now pull/rebase from the upstream repository

git pull upstream master

And push now push these changes to your forked repository

git push

Also you should run the following

git config --global "Your Name"
git config --global <your_email>

How to Build Jentrata from source

Requires maven 3.0+ and Java 6+

git clone<github-username>/jentrata-msh.git
cd jentrata-msh
mvn clean install

This will create jentrata-msh-tomcat.tar.gz in jentrata-msh/Dist/target/ as well as an uncompressed version

How to get Jentrata Running on tomcat using PostgreSQL on unix (incuding Mac) systems

Install and configure Tomcat

  1. download and install tomcat 6.x or 7.x

  2. untar jentrata-msh-tomcat.tar.gz

  3. set JENTRATA_HOME and TOMCAT_HOME environment variables, for example

     export JENTRATA_HOME=/dev/jentrata-msh-tomcat
     export TOMCAT_HOME=/dev/tomcat
  4. create a symlink to the $JENTRATA_HOME/webapps/corvus in the $TOMCAT_HOME/webapps directory to

     ln -s $JENTRATA_HOME/webapps/corvus $TOMCAT_HOME/webapps/jentrata
  5. set JAVA_OPTS environment variable as follows

     export JAVA_OPTS="$JAVA_OPTS -Dcorvus.home=$JENTRATA_HOME"
  6. add the following roles and user to $TOMCAT_HOME/conf/tomcat-users.xml

     <role rolename="admin"/>
     <role rolename="corvus"/>
     <user username="corvus" password="corvus" roles="tomcat,admin,corvus"/>

Install and configure database


  1. install postgresql 8.3+ - During the install, for the default user 'postgres', make the password 'postgres' (ignore quotes). For Mac OSX you should read the link - memory configuration info for OSX

  2. copy the database creation scripts to your PostgreSQL install

     copy JENTRATA_HOME/sql/ebms.sql to the PostgreSQL bin directory
     copy JENTRATA_HOME/sql/as2.sql to the PostgreSQL bin directory
  3. log in as the PostgreSQL user 'postgres' created during the install

  4. set the password for the default user 'postgres' as a temporary environment variable

     export PGPASSWORD="postgres"
  5. cd to the PostgreSQL bin directory

  6. create a postgres user corvus with default password corvus

     ./createuser -s -d -P corvus
  7. create the ebms and as2 databases

     ./createdb -O corvus ebms
     ./createdb -O corvus as2
  8. Run the db create tables scripts

     ./psql -f ebms.sql ebms
     ./psql -f as2.sql as2
  9. Logout as user postgres


  1. Install MySQL for your OS (

  2. Create your databases

     mysql -e "CREATE DATABASE ebms;"
     mysql -e "CREATE DATABASE as2;"
  3. Create users/permissions to new databases

     mysql -e "GRANT ALL ON ebms.* TO 'ebms'@'localhost' IDENTIFIED BY 'ebms';"
     mysql -e "GRANT ALL ON as2.* TO 'as2'@'localhost' IDENTIFIED BY 'as2';"
  4. Import DB Schema

     mysql ebms < JENTRATA_HOME/sql/mysql_ebms.sql
     mysql as2 < JENTRATA_HOME/sql/mysql_as2.sql
  5. Configure Jentrata to use MySQL

    You will need to modify the some parameters of the doafactory component in the 'plugins' directory for each plugin of Jentrata that you wish to use with MySQL.


    Look for the following Component:

     <component id="daofactory" name="System DAO Factory">

    Find the following parameters and change them as follows:

     <parameter name="driver" value="com.mysql.jdbc.Driver"/>
     <parameter name="url" value="jdbc:mysql://"/>

Run Jentrata

  1. Start tomcat and browse to http://localhost:8080/jentrata/admin/home. You will need to login using the username and password you set in the tomcat-users.xml corvus/corus by default

  2. If Jentrata doesn't start correctly you can check the various log files under $TOMCAT_HOME/logs/ or $JENTRATA_HOME/logs for errors

Running Jentrata with Docker

Jentrata provides a Dockerfile and also a docker-compose.yml file. The Dockerfile is used to buid a general docker image for Jentrata. The docker-compose file is to speed up development. It contains preset variables.


If Jentrata's docker container doesn't detected a postgresql server on the configured hostname and port, it will pause and retry to connect until one is made available.


Jentrata in docker assumes that you're using Postgresql. The docker-compose sets up a docker image with this preconfigured.

Start Jentrata using Docker Compose

Docker compose makes it easy to bring up a series of docker images in conjunction with each other.

    docker-compose up

This has everything pre-configured and ready to go. You can acccess Jentrata on: http://localhost:8080/jentrata/admin/home

Extra: Build the docker container

If you want to build the checked out version of Jentrata, or you want to avoid using the docker hub you can build the docker image like follows:

    docker build -t jentrata/jentrata-msh .
