Hi Expert, I have posted a problem about the drools session persistence in StackOverflow, but have not got answer for 10 days. http://stackoverflow.com/questions/21928187/how-to-configure-to-reload-th... I would like to re-post the problem here I am using the drools server 5.5 Final with Spring to configure the knowledge session to persist to database(mysql) and expect it will reload the session when server(tomcat) restart. code snippet as below I can see it will insert the session info to Mysql when Tomcat restart each time How to configure to reload the session from Database if the session has been persisted before？ after several days searching, Finally, we happen to see the src code of KnowledgeSessionDefinitionParser which will parse the spring configuration file http://grepcode.com/file/repo1.maven.org/maven2/org.drools/drools-spring/... in the code, it will get the value of 'load' attribute and use as the sessionId to reload. so we tested to add load="sessionId" and it is ok to reload. but if config the sessionId to a number which does not exist in the DB, it will throw exception For a real application, it is impossible to know the sessionId when do the src configuration, also have not found drools have provided any way for us to pre-set the sessionId. so is it the correct solution?
