Class Cast exceptions in Resin almost always occur because you also have an old or alternative "jsdk.jar" or "servlet.jar" in your classpath. Make sure that only the Resin one is present in the classpath you use to invoke Resin.
closing server java.lang.ClassCastException at com.caucho.server.http.ResinServer.execute(Compiled Code) at com.caucho.server.http.ResinServer.main(ResinServer.java:390) at com.caucho.server.http.RunnerServer.main(RunnerServer.java:123) this is all I get when ever I stop or Press Quit button. and i think the class path is causing the problem. But as installed as NT services it works fine. Can somebody tell me the number of concurrent connections i can make? thanks ravee.
