The eclipse plugin is not required to write a program to translate a
class file to a jimple file. You only need, soot, jasmin and polyglot
jars/classes in your classpath.

Using the eclipse plugin you can easily convert a file to jimple from
inside eclipse; a soot option should appear when you right click on a
file in the package explorer in eclipse if the plugin installed
correctly.

I use the function given below to retrieve Soot bodies for the
application classes. As far as I remember something like this occurs
when you invoke Soot.

       private static void retrieveAllBodies() {
               Iterator clIt = Scene.v().getApplicationClasses();
               while (clIt.hasNext()) {
                       SootClass cl = (SootClass) clIt.next();
                       Iterator methodIt = cl.methodIterator();
                       while (methodIt.hasNext()) {
                               SootMethod m = (SootMethod) methodIt.next();

                               if (m.isConcrete()) {
                                       m.retrieveActiveBody();
                               }
                       }
               }
       }
