[rules-users] Extracting an boolean variable

I tried to extract a boolean variable from a class using context. The
following is my code in DSL file.

context : Context(state == START_UP) Classname(aliasname :
booleanVariableName)

When I tried to run this statement I got the following error message in DRL
file.

Error Message: Unable to Create Field Extractor for 'booleanVariableName'.

But when I tried to extract a String Variable the Error is cleared.

Can Someone explain me about this problem in Drools.

Thanks.
