I am building portlets (jsr 168 api in Websphere Portal 6.0 using web service client of Rational). Now needed some suggestions on caching the web services data on the portlet. We have a number of portlets (somewhere around 4 or 5) on a portal page which basically rely on a single wsdl Lotus Domino Web Service.
Is there a way I can cache the data returned by webservice so that I dont make repeated calls to the webservice on every portlet request. Any best practices/ideas on how I could do avoid multiple web service calls would be appreciated ?
