The latest release from the 2.0 series (2.0.3) is the current stable release. We recommend that you use this if you are looking for a stable release. 2.0 implements the latest Java Portlet Specification and requires Java 5 minimally.
All Pluto 1.x versions are no longer active and only maintained for bug fixes.currently under development.
Pluto 1.0.x is based off of the code base which was originally donated to the ASF by IBM. The first release candidate in this series was published on October 8, 2004. Pluto 1.0.x is only maintained for bug fixes.
Pluto 1.0.1 is the portlet container embedded in all Jetspeed release up until version 2.2.0. From version 2.2.0 onward, Jetspeed embeds Pluto 2.0.x.
The 1.1.x series is a refactoring/rewrite of Pluto 1.0.x. It's entire purpose is to simplify the container and make it easier for both Portlet Developers and Portal Developers looking to embed Pluto into their portal to use Pluto.
Now that Pluto 2.0.0 has been released, our team highly recommends that you migrate to it. Pluto 1.0.x development has been stagnant for some time and there are no plans to support it in the future.
Simple, use the Pluto Portal Drivers "PortalDriverFilter". This allows you to embed a portlet directly into a jsp page. To use it, do the following:
As of Pluto 1.1.5 you can change the default encoding of the Pluto Portal by editing the Pluto Portlet Servlet's web.xml. Add an init-param with the name of "charset" and set the value to the desired character set.
If you have installed Pluto 1.1.5 or greater, and are running on Java 5 or greater, then you do not need to endorse any XML libraries. Pluto will use JAXP.
The Pluto 1.1.x codebase targets Java 1.4, and so the bundled
distribution of Pluto includes Tomcat with XML libraries in
common/endorsed. Simply remove the XML libraries
common/endorsed if you meet the above requirements.
