java ee - Out of memory error in drools -


i using drools5.5 , creating knowledge bases required drls , decision tables execute rules. in that., when try load decision table(which xls has 20,000 lines) in knowledgebuilder getting out of memory exception.i have used following piece of code

knowledgebuilder knowbuilder = knowledgebuilderfactory.newknowledgebuilder(); knowbuilder.add(resourcefactory.newfileresource(filelocation),resourcetype.determineresourcetype(filelocation));

when execute this., getting java heap space error , permgen space error. there other way load large sized rulefiles in drools efficiently.

the question how big xls file in memory , how many objects being created? inserting facts session? heap size?
