Setup

Make sure /cloud project is downloaded Start up eclipse and open it in cloud directory

(something like /home/scott/cloud) ssh -X ubuntu@123.45.111 to be able to open X

sessions if doing this on cloud [Screenshot]

Setup (Eclipse)

Close front window and right click on left to open a New Project

Setup (Eclipse)

Title the project cloud and hit Finish [Screenshot]

Go to util/src/cloud/LoadRestfulWebService.java

LoadRestfulWebService Explained

Typical protocols

– Http, https, REST, JSON, 1-way SSL (https), 2-way SSL (https with identity assertion)

LoadRestfulWebService

– Uses RESTful service to load users, groups, and roles

– Calls cloud application and loads data into SOLR

LoadRestfulWebService Explained

Main() adds roles, groups, and users AddUser(), AddRoles(), AddGroups()

– Gets properties from properties file

– Gets URI information to fill in user data• Category is 'table name'

– Sends data to servlet that writes to SOLR GetProperties()

– Gets data from load.properties

– Files are either on the web or off the classpath, load.properties is off classpath

JSONUpdateServlet

Go to cloud-war/src/java/cloud/servlets/JSONUpdateServlet.java

[Screenshot]

JSONUpdateServlet

Takes data from URI that is sent RESTfully and writes it to SOLR

WriteToSOLR() already exists and should be used to write to SOLR

Where to Start?

Cloud-functional-tests/src/TestAdd.java [Screenshot]

TestAdd.java

Test program that goes to SOLR, makes a request

– JUNIT test uses asserts to see if the test passes or fails. If assert line is true, test works, if not, then test does not work.

Seeing if cloud works

Go to cloud/cloud/solr.solr.home/collection1/data and do an rm -rf *

Go to terminal, start tomcat with 'st' In other window, cd to /cloud/cloud and type:

ant deploy [Screenshot]

Seeing if cloud works

In cloud/cloud do:

ant run-clear-index

ant run-load-web-service In browser go to:

localhost:8080/cloud/select?q=*:*&rows=100

Cloud Project Continued

You have to add a login module to cloud

– Already added in for you Files to take from adjudicator_software folder

in content.scottstreit.com/compsec

– Jaas.config goes in tomcat config directory

– RolePrincipal.java

– SolrLoginModule.java• It gets called in web.xml

– There are security constraints and login-configs in web.xml

SolrLoginModule

SolrLoginModule.java• It gets called in web.xml

– There are security constraints and login-configs in web.xml

– <auth-method>BASIC</auth-method> for login-config

JUNIT Test Attempt

In cloud/cloud run the following:

ant run-tests [Screenshot]
