J2EE does not allow File I/O so it may be that your app server does not allow it by default and you need to give your application permission to do it. This would generally be done in a policy file (in WebSphere it is was.policy ).

I want to call rules from session bean. I implement this by calling a utility
callss from the Session bean method.
That Utility class load the rule file as

"final Reader source = new
InputStreamReader( BaseRuleImpl.class.getResourceAsStream(rulefile));"

this gives the result as expected. But it throws an exception in the server
as follows,(Server log)

java.lang.Throwable

com.argosoftware.rules.ejb.session.LogicHandlerBean.ruleHandler(LogicHandlerBean.java:42)

I think this is because of the IO operation.
Can anybody kindly suggest a solution for this.?
