I've made available a version of the smallx pipelines and servlet integration.
In the 'xml' directory is the supporting XML technology for pipelines and standalone examples.
In the 'server' directory is the supporting J2EE integration for pipelines and example web applications.
Each example is a netbeans project that you can open.
The examples are as follows:
xml/examples/ - example pipelines and components
server/webapps/XMLPost - an example JSP application for posting XML content to web services.
server/webapps/bart-service - The bart.gov screen-scrapping example web service.
server/webapps/mystuff - The example front-end to bart-service.
server/webapps/rss-feed-service - An RSS feed converter that turns the descriptions into XML.
server/webapps/rss-feed - An example front-end to the RSS feed service.
server/webapps/contacts-service - A contacts database web service.
server/webapps/contacts - an example front-end to the contacts web service that supports mobile devices.
server/webapps/pipeapp - an extremely simple test of the pipe integration.
server/webapps/xsltapp - an extremely simple test of the XSLT filter.
