XACML Architecture

1. Its an access control policy language.

2. The Identity Server supports XACML 3.0, which is based on Balana XACML implementation.

3. The XACML engine of the WSO2 Identity Server has two major components, i.e., PAP and PDP.

Eg:

MyPolicy.xml

==========

<AnyOf>

<AllOf>

<AttributeDesignator AttributeId="urn:oasis:names:tc:xacml:1.0:action:action-id" Category="urn:oasis:names:tc:xacml:3.0:attribute-category:action"

</Match>

</AllOf>

</AnyOf>

</Target>

</Policy>

Request

Java Script Basics

[1] Calling a function of another file from your javascript file

file 01: graphinventor.js
=================

console.log("-----------------------------------------Time Unit ");
console.log("Previous Time Stamp ");

var test123 = function (data){
console.log("-----------------------------------------inside test123 ");
console.log(data)
alert("This is an alert" +data);

}

[3] https://datatables.net/manual/ajax

file 02: gadgetconf.js
===============

processData: function(data) {

console.log('data '+JSON.stringify(data));
// in console of the browser (Ctrl+c) you see the content now as json data

console.log("------------------------");
test123(data);
console.log("------------------------");

}

main.js file (Loading graphinventor.js file first)
==========


<script src="js/graphinventor.js"></script>
<script src="js/gadgetconf.js"></script>
<script src="js/main.js"></script>

[2] Callback function is a function passed into another function.

2. Uncomment below.

<H2DatabaseConfiguration>
<property name="web" />
<property name="webPort">8082</property>
<property name="webAllowOthers" />
<property name="webSSL" />
<property name="tcp" />
<property name="tcpPort">9092</property>
<property name="tcpAllowOthers" />

<property name="pg" />
<property name="pgPort">5435</property>
<property name="pgAllowOthers" />
<property name="trace" />
<property name="baseDir">${carbon.home}</property>
</H2DatabaseConfiguration>

3. Navigate to your primary datasource which points to the H2 datasoure to identify username & password.

eg:

<datasource>
<name>WSO2_CARBON_DB</name>
<description>The datasource used for registry and user manager</description>
<jndiConfig>
<name>jdbc/WSO2CarbonDB</name>
</jndiConfig>
<definition type="RDBMS">
<configuration>
<url>jdbc:h2:./repository/database/WSO2CARBON_DB;DB_CLOSE_ON_EXIT=FALSE;LOCK_TIMEOUT=60000</url>
<username>wso2carbon</username>
<password>wso2carbon</password>
<driverClassName>org.h2.Driver</driverClassName>
<maxActive>50</maxActive>
<maxWait>60000</maxWait>
<testOnBorrow>true</testOnBorrow>
<validationQuery>SELECT 1</validationQuery>
<validationInterval>30000</validationInterval>
<defaultAutoCommit>false</defaultAutoCommit>
</configuration>
</definition>
</datasource>
