Re: [rules-users] StackOverflowError when serializing KnowledgeBase

From: Andargor <andargor(a)yahoo.com&gt; Subject: StackOverflowError when serializing KnowledgeBase To: rules-users(a)lists.jboss.org Date: Thursday, July 22, 2010, 8:10 PM Hello, After adding a few hundred rules, and with the same code, KnowledgeBase serialization has started to generate StackOverflowError. I have increased the VM stack size as a workaround, but I was hoping to implement something more robust. I specifically need to serialize the KnowledgeBase, and not the session. I'm using this code:     private void dumpKnowledgeBase(String file, KnowledgeBase kbase) {            try {                FileOutputStream ostream = new FileOutputStream(file);                DroolsObjectOutputStream p = new DroolsObjectOutputStream(ostream);                p.writeObject(kbase);                p.flush();                ostream.close();            }            catch (Exception e) {                System.err.println(e);                e.printStackTrace();                System.err.println("Could not write knowledge base "+file);            }     } This is due to writeObject recursion? Any ideas? A.
