Return of serialize/deserialize - HashMap of Compiled Rule Bases. ----------------------------------------------------------------- Key: JBRULES-631 URL: http://jira.jboss.com/jira/browse/JBRULES-631 Project: JBoss Rules Issue Type: Bug Security Level: Public (Everyone can see) Components: All Affects Versions: 3.0.1 Environment: Websphere 6.0. Reporter: Joe Son Assigned To: Mark Proctor I'm trying to deserialize hashMap of compiled RuleBases back so that i can use it. I've tried out different ideas but this one kinda kills me as to why i am getting this error. It is compiled and serialized during the start up of the webserver (webapp). When the web app is restarted, it uses the same classloader to load the file from the disk. I get this error below: Am I getting this because of difference in classloader instances? say first time around classloader instance A does the serialization. Then when it come time for deserialization during webapp restart, classloader instance B does the desrialize. Could this cause such error below? I'm also using JANINO compiler. Please help. java.lang.ClassNotFoundException: rules.Rule_dept00004_10_0ConsequenceInvoker at java.net.URLClassLoader.findClass(URLClassLoader.java(Compiled Code)) at
