Can I use Active Server Pages (ASPs), Perl, or Cold Fusion to develop portlets?
PDK URL Services, available with the April 2001 release of the PDK, support portlet creation with languages such as ASP, PERL, JSP, Java Servlets, and others, without the requirement to alter existing applications. URL Services extends the JPDK and creates portlets based on URL rendering. The URL Services includes multi-language portlet samples and articles that explain the architecture and how to create your own ASP and PERL portlets.
