The PressGang CCMS REST Server project provides a RESTful web interface for the PressGang CCMS (Component Content Management System). It offers create, update, get and delete endpoints for the system's primary entities. These endpoints produce both JSON and JSONP, which adds cross-domain functionality. Topic entities also have ATOM, XML and HTML get endpoints.

PressGang CCMS REST Server

This project is setup to run on JBoss AS 7.1.1. See below for setup steps:

Prerequisites

• Downloaded and Extracted JBoss AS 7.1.1 to a location of your choice (referred to as <JBOSS_DIR> in this guide).
• Setup and installed a RDBMS database of your choice.
  • Note: Currently we only have a setup for MySQL 5.x
• Installed and configured Maven.
• Have the OSS Sonatype Repository setup in your local settings.xml (to be able to compile).

Configure JBoss AS 7.1.1

1. Open the Standalone Configuration located at <JBOSS_DIR>/standalone/configuration/standalone.xml

2. Add the following System Properties and populate it with relevant data.

    <system-properties>
        <property name="topicIndex.bugzillaUrl" value="bugzilla.redhat.com"/>
        <property name="topicIndex.bugzillaUsername" value=""/>
        <property name="topicIndex.bugzillaPassword" value=""/>
        <property name="NumberOfWorkerThreads" value="1"/>
        <property name="topicIndex.kerberosEnabled" value="false"/>
        <property name="topicindex.rerenderTopic" value="false"/>
        <property name="java.security.krb5.kdc" value=""/>
        <property name="java.security.krb5.realm" value=""/>
        <property name="topicIndex.instanceName" value=""/>
        <property name="topicIndex.zanataServer" value=""/>
        <property name="topicIndex.zanataProject" value=""/>
        <property name="topicIndex.zanataUsername" value=""/>
        <property name="topicIndex.zanataProjectVersion" value=""/>
        <property name="topicIndex.zanataToken" value=""/>
        <property name="topicIndex.defaultLocale" value="en-US"/>
    </system-properties>
   

3. The next step is to add the data source configuration. Below is a sample configuration:

    <datasource jta="true" jndi-name="java:/PressGangCCMSDatasource" pool-name="PressGangCCMSDatasource" enabled="true" use-java-context="true" use-ccm="true">
        <connection-url>jdbc:mysql://localhost:3306/PressGangCCMS?jdbcCompliantTruncation=false&amp;useUnicode=true&amp;characterEncoding=UTF-8</connection-url>
        <driver-class>com.mysql.jdbc.Driver</driver-class>
        <driver>mysql</driver>
        <transaction-isolation>TRANSACTION_READ_COMMITTED</transaction-isolation>
        <pool>
            <min-pool-size>20</min-pool-size>
            <max-pool-size>151</max-pool-size>
            <prefill>true</prefill>
            <use-strict-min>false</use-strict-min>
            <flush-strategy>FailingConnectionOnly</flush-strategy>
        </pool>
        <security>
            <user-name></user-name>
            <password></password>
        </security>
        <validation>
            <validate-on-match>false</validate-on-match>
            <background-validation>false</background-validation>
            <use-fast-fail>false</use-fast-fail>
        </validation>
        <statement>
            <prepared-statement-cache-size>50</prepared-statement-cache-size>
            <share-prepared-statements>true</share-prepared-statements>
        </statement>
    </datasource>
    <drivers>
        <driver name="mysql" module="com.mysql"/>
    </drivers>
   

4. Now create a Keystore that will contain the Self-Signed SSL Certificate for HTTPS communication. You can do this by running the following command:

    keytool -genkey -keyalg RSA -keystore keystore.jks -keysize 2048
   

5. Add the configuration to the Web Subsystem. The following is an example of what it could look like:

    <subsystem xmlns="urn:jboss:domain:web:1.1" default-virtual-server="default-host" native="false">
        <connector name="http" protocol="HTTP/1.1" scheme="http" socket-binding="http"/>
        <connector name="https" protocol="HTTP/1.1" scheme="https" socket-binding="https" secure="true">
            <ssl name="https" password="<PASSWORD>" certificate-key-file="<KEYSTORE_LOCATION>"/>
        </connector>
        <virtual-server name="default-host" enable-welcome-root="true">
            <alias name="localhost"/>
            <alias name="example.com"/>
        </virtual-server>
    </subsystem>
   

6. The last step is to unzip the MySQL Driver and Hibernate Module into the Modules directory. The archive can be found at program-resources/modules.zip in this repository.

Importing the Base Database

Supplied is a MySQL Database backups that contains the core components for the Server to run. The supplied SQL will create a Database called PressGangCCMS, relevant Tables and any initial data.

Compiling the Source

1. Ensure that you have Maven setup and the OSS Repository setup in your settings.xml

2. Run:

    mvn clean package
   

Installing to the Application Server

1. Ensure that the Application Server is running by opening another terminal and navigating to <JBOSS-DIR>/bin and execute the standalone.sh script.

2. In the first terminal run the following command:

    mvn clean package jboss-as:deploy
   

Increasing the file limit

The default open file limit on RHEL is 1024, which is not enough if you have a few users. Edit /etc/security/limits.conf and add the following lines

• soft nofile 4096
• hard nofile 4096
