Re: [rules-users] "From" clause and connection time outs - suggestion

Hi, in a load intensive operation, if a pool of JDBC connections is exausted the 'from' breaks. Ok, it should! (Not expecting magic :o) ) ,.. but I'm concerned about the trace it generates. The stack trace does not suggest the ground reality and is very abstract. Can you have an enhacement to wrap the actual exception or atleast say somewhere he "from" failed? org.mvel.MVEL.executeExpression(MVEL.java:219) org.drools.base.dataproviders.MVELDataProvider.getResults (MVELDataProvider.java:45) ... I could figure out from the following lines what was wrong, but someone else may not be able to figure it out. It's not that big a deal, but just a suggestion since I think in high load conditions this would be a common error.
