You can download several distributions from Sourceforge.
Choose the binary distribution if you want to develop a J2ME application using StrutsME . This includes the 3 jar files for the 3 modules StrutsME-Common , StrutsME-Client and StrutsME-Server . In addition the javadoc files are also included. This also includes the sample application called "Wishlist". It can be used to get a feeling for StrutsME . It consists of the WAR-file for the server and the jar and jad file for the mobile client.
If you want to change or extend StrutsME or just want to take a look at the source code the source distribution is your choice.
