JetChart can be integrated into servlets, Java Server Pages and JavaBeans to deliver JPEG, PNG, GIF and SVG chart images to client browsers. There is a tutorial here outlining the steps to implement charting servlets, either by using the built-in encoders found in the JetChart class library or the Java Advanced Imaging(JAI) package.
There is also a war(Web Application Archive) file available in the folder
JetChart/demo/servlets, named jetchart.war.
A war file is a zip-compressed file containing the resources of a web-application, as
static html pages, Java Server Pages, JavaBeans and servlets, all of them placed at folders
within a framework whose structure adheres to the Servlet API Specification, version 2.2 or
later, for the correct deployment in conforming servers.
Typically, a war file is automatically expanded by a servlet engine, provided it is placed
at the expected location. For example, if the jetchart.war file is copied into the webapps
folder of Tomcat/Jakarta, it is automatically expanded during Tomcat initialization.
Nevertheless, the war file can also be manually expanded using any zip file decompressor.
Please refer to your server documentation to get instructions on how to correctly
deploy a war file.
