use the kstore element. You already have the various jpa settings in spring as beans. So you can retrieve those and pass them as parameters to the kstore in java code; which follows exactly the same interface as JPAKnowledgeService. Mark On 28/07/2010 15:41, tolitius wrote: > 1. If there is n

Dan, I am not aware of any memory leak in CR1. If you can provide me with a test case I will investigate this today. Please open a JIRA, attach your test case and let me know. If there is a leak, I need to fix it before final release. And it is not a problem to instantiate object

There are two other solutions if you do need the p: 1. Change your condition to be "name matches $param", this will match as a regular expressions. Your general case can then be ".*". 2. Merge your p:CProduct across two columns. Have a condition of "this != $param" for the first co

I think that Sean worries about the overhead of n*1000 calls to fireAllRules, as opposed to a single call. Also, a different heap usage/GC pattern could impact timing. A potential benefit of the second approach would be that results from first firings are available sooner than with the 1st approac

fireAllRules will only fire all the rules that where activated during the insertion phase. So basically when you call it at the end, it will only fire all those rules activated. If you insert a fact that doesn't activate any rule you don't need to call fire all rules. On Tue, Jul 27, 2010 at 1:54
