Thanks Edson,

I Went throught the documentation.
I cerate  a small rule & its laod & evaluate ok.
But when I try to load a some bit large rule it stuks & thorws following
exception:

which is more than the configured time (StuckThreadMaxTime) of "600"
seconds. Stack trace:

My questions are:
i) How can I increase the time.
ii) Currently I am using some thng as follows in our drl file:

when
	#conditions	

		eval(cdaUtil.compareObservation("Blood Glucose", "82947",
"2.16.840.1.113883.6.12", "<93312000000", "", "", "", "",
"").equals("false")  )
	
					and
			
			eval(cdaUtil.compareDiagnosis("Coronary Artery Disease", "414.8",
"2.16.840.1.113883.6.2", "").equals("true")  )

:
:
:
more conditions as above. around 40 -50 with OR / AND .

Actualy we have a class which have methods such as (compareObservation,
compareDiagnosis etc) to evaluate those conditions, We were using this
methodology in Weblogic rule xml too.
We don't have a class with attributes to set & evluate.  So is the above
logic I ma using is ok or could you suggest some other drl way to evaluate
such rules.

Thanks
