Need help with rsbot for mac

alright so i need a bit of help for rsbot for my mac. I have gotten the lastest verson using svn. I however then when i try clicking on any of the sh files it just opens in textedit. i tried running it throught terminal however it returns this errror no matter witch one i choose

Code:

Exception in thread "main" java.lang.UnsupportedClassVersionError: Bad version number in .class file
	at java.lang.ClassLoader.defineClass1(Native Method)
	at java.lang.ClassLoader.defineClass(ClassLoader.java:675)

	at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:374)

Any help is appricated.


Also on a side know how do a do a space in terminal? ie i type

Code:

sh compile all.sh

and it returns.

Code:

sh: compile: No such file or directory

meaning it doesn't read the space. i tried a _ but the only way i could get it to work was by changing to the name no space.


EDIT: figured it out myself.

first go to software update and make sure you are up to date (apple logo in top right hand corner->software updates)

For anyone else who wants to know go to spotlight (command space) or top right hand corner type in java and the top hit should be java preferences. click on that. drag java se 6 to the top of both lists

hope that helps
