Installation

The Tomcat Virtual Platform can be deployed on a gHN by uncompressing the related archive inside the $GLOBUS_LOCATION//virtual-platforms folder:

tar -zxvf org.gcube.vre-management.virtualplatform-tomcat-X.tar.gz

This will create a $GLOBUS_LOCATION//virtual-platforms/Tomcat6 folder with the resources needed to enable the Tomcat 6 platform. Afterwards, the tar.gz archive and the doc folder (also created by the command above) should be removed.

gHN Configuration

Download, install and configure a Tomcat 6.0.X instance (tests has been made with version 6.0.32).

Then next step is to add a user with the privileges needed to perform deployments on the instance. This is done by adding the following lines to the $CATALINA_HOME/conf/tomcat-users.xml file:

<tomcat-users>

 <!-- other config settings -->

 <role rolename="manager-gui"/>
 <role rolename="manager"/>
 <role rolename="manager-script"/>
 <user username="USERNAME" password="PASSWORD" roles="manager-gui,manager,manager-script"/>
</tomcat-users>

where USERNAME and PASSWORD are chosen by the Site Manager.

Do note that the Tomcat 6 instance can be hosted on any machine, not only on the one hosting the Tomcat Virtual Platform. This is because the interaction between the two are performed with a network protocol (HTTP).

Platform Configuration

The final step is to configure the Tomcat Virtual Platform for interacting with the Tomcat 6 instance.

In the $GLOBUS_LOCATION//virtual-platforms/Tomcat6 folder, edit the
