Configuring SSO Using WSO2 Identity Server

Single sign-on is a feature that allows users to access more than one application with the same credentials. This article shows how we can configure SSO using the WSO2 Identity Server. There is a cab company called Pickup that has two web applications called pickup-manager and pickup-dispatch, which use WSO2 IS as their identity provider. After SSO configuration is done for both applications, the users need to provide credentials only for one application, and they can automatically log in to the other application. This article shows SSO implementation using two ways — SAML 2.0 and OpenID Connect/OAuth 2.0.

appsPrerequisites

  1. WSO2 Identity Server (IS) 5.11.0.
  2. Apache Tomcat 8.5.
  3. Download saml2-web-app-pickup-dispatch.com.war, saml2-web-app-pickup-manager.com.war and pickup-dispatch.war, pickup-manager.war from this repository.

Implementation Steps (SAML 2.0)

1. Start the WSO2 IS server by running wso2server.bat or wso2server.sh present under <WSO2IS_HOME>/bin.

Building a REST Service That Collects HTML Form Data Using Netbeans, Jersey, Apache Tomcat, and Java

The Jersey project is very well documented so it makes it easy to learn REST with Java. In this article I’m going to build two projects. The first project will be a very simple HTML page that presents a form to the user and then submits it to a REST project residing on the same server. The second project will be the REST part.

For this article I used the following tools:
1. Netbeans 7
2. Apache Tomcat 7
3. Jersey
4. Java

What Do We Know About Tomcat 9.0

Apache Tomcat is a very popular and preferred industry choice for web application development as a Servlet/JSP container. Apache Tomcat version 9.0 implements the Servlet 4.0 and Java Server Pages 2.3 specifications from the Java Community Process and includes many additional features that make it a useful platform for developing and deploying web applications and web services.

I take this opportunity to summarize some of the new features in Tomcat 9.0 and steps to keep in mind before upgrading from Tomcat 8.x to Tomcat 9.0.
