I did add that.

Did you use my latest code (including the scripting.jar that I extracted from 
JDK1.6)? I attached it again.
Your attached script suggests that you are still using the downloaded one that 
for some reason lacks the "Bindings" class.


$ ./build.sh
gcjtest/main.cpp
gcjtest/build.sh
gcjtest/scripting.jar
testgcj
Create JavaVM ...
Create JavaVM done.
Java Exception:
java.lang.NoClassDefFoundError: javax.script.ScriptEngineManager
   at java.lang.Class.initializeClass(libgcj.so.10)
Caused by: java.lang.NullPointerException
   at java.lang.Class.initializeClass(libgcj.so.10)
