Java portal servers

A continuing cause of delivery problems lies in the use of Java Portal Server packages. These problems occur in both open source and commercial portal platforms. The promised productivity of these platforms is hindered by their complex and unwieldy programming models and difficulty in automating deployment, data migration, and tests. Although product demos are compelling, the base features of portal products are often a poor fit for real web applications, while the extra advertised features such as single sign-on or search are usually already served by existing, targeted, enterprise assets.
