help: connection pool

[Hengtai Yu]

Hi, I try to set up connection pool using one of 2 methods:both fail! 1. DMConnectionManager.java (written by Hans bergsten), when I test it, message always is :can't get connection. Both DMConnectionManager.java and example file TestServer.java pass compile. and I have put DMConnectionManager.class in classpath, why? 2. I use another one: ServletConnection.java , ConnectionPool.java (with Timer and TimerListener class) (written by Karl Moss, in book:Java Servlets) and test file FastEmployeeList1.java. Error message is:  can not load ServletConnection.class and FastEmployeeList1.class, JWS can not find them (even I can see them after compile them). Why?   I use window NT with jws1.1.3 and jdk1.2, jdsk2.0.   Thanks in advance   Hengtai
