Built a J2EE portal for Aon International. Aon connected all of its customers (400+) to this portal that is used to share information and collaborate. The portal was IBM WebSphere’s Portal Server 4.1.4. As part of my work I was involved in the Proof of Concept phase, the design phase as well as implementation. I developed different portlets, including Single Sign On portlets to remote applications and static content portlets. WSAD was used as the development environment. As part of the portal initiative users, user groups, and access permissions needed to be migrated. Java software was created to generate XML files that were then used as input by Portal Server’s XML Access tool to generate places, pages, portlets, and access rights within the portal as well as user groups and users in the LDAP directory server.
I was also involved in Proof of Concept for Rabobank, using WebSphere Portal Server 4.2. For this project Struts portlets were developed. This entailed the combination of portal technology and the Struts framework.
