Trying again (after reading your private email): I tried to start
libary(rJava) after each of the following line, and the result
was always the same.

shell("where jvm.dll")
#C:\Program Files\Java\jre6\bin\client\jvm.dll
Sys.getenv("JAVA_HOME")
# JAVA_HOME
#"C:/Program Files/Java/jre6/bin"
Sys.setenv(JAVA_HOME="C:/Program Files/Java/jre6")
Sys.setenv(JAVA_HOME="C:/Program Files/Java/jre6/bin")
Sys.setenv(JAVA_HOME="C:\\PROGRA~1\\Java\\jre6")
Sys.unsetenv("JAVA_HOME")
