Trying to set up a BD-J development environment on my windows 7, 64-bit system, but when I run the ME Platform SDK 3.0, I get the subject error (java.net.ConnectException: Connection refused: connect)
So after googling around, stockoverflow to the rescue (see the top comment by Kevin).
After I saw that, I installed 32-bit Java from here, and then updated the paths in the 2 files named “java” (in installDir\bin and installDir\toolbar\bin) – I updated both; replaced the path with the path to the newly installed 32-bit JDK and then it worked.
