Hi,

That is strange. Your mail said:

        java.lang.NoClassDefFoundError: My_Plugin(wrong
        name:plugins/My_Plugin

This suggests that somehow this plugin is compiled as if it were in the
package "plugins". With current ImageJ, it is not sufficient to put the
resulting class file in the directory "plugins". You _have_ to build a jar
if your class is in some package.

Maybe your compile script does strange things?

Not to me. The final "jre" says that it is a Java Runtime Environment
(JRE), as opposed to Java Development Kit (JDK).

Hth,
