Servlex, an implementation of the EXPath Webapp framework (see also the current draft of the spec). The homepage is at http://servlex.net/.
Download the latest servlex-x.y.z-installer.jar file from the
download area and
execute it by double-clicking on it (or from the command-line: java -jar servlex-x.y.z-installer.jar). Follow the instructions, that's
it!
If you want to install Servlex into the servlet container of your
choice, use the latest servlex-x.y.z.zip file instead. It contains
a suitable WAR file and install instructions.
There is nothing to setup if you use the graphical installer. Just
start Servlex by executing bin/startup.sh (resp. bin/startup.bat
on Windows) and go to http://localhost:19757/. You can change the
default port number in conf/server.xml.
If you install the WAR file yourself, you have to point the property
org.expath.servlex.repo.dir to a repository on the disk. On Tomcat
for instance, you can add the property to conf/catalina.properties.
Once installed, you can access the Servlex Admin Console at
http://localhost:19757/manager/home. From there you can deploy the
sample web application in the release, hello-world-x.y-z.xaw, by
filling in the form. Go to http://localhost:19757/servlex/hello-world/
to access the example once installed. The sources are available in the
dir hello-world/src/.
This sample application is just a few forms, each one-field, sending a string to either an XSLT function, an XQuery function or an XProc step, which in turn responds with a page based on this parameter. You can use the tool http://h2oconsulting.be/tools/dump to display the XML representation of the HTTP request which is send to the XSLT, XQuery and/or XProc components in a web application.
Some docs about Servlex are also available here and there on the EXPath's wiki.
Servlex is used to run CXAN (as well as its Sandbox), the sources of which are available on GitHub. The EXPath website runs on Servlex too (see the sources). H2O Consulting website runs on Servlex as well.
