Tomcat 3.x的是不支持Connect Pool的，在Tomcat 4.x中就支持。 Tomcat (talking about version 3.x.x) is the reference implementation of the webapp part of J2EE (ie, no EJB). In this spec connection pooling is not contemplated.You can however use pooling by using the JDBC 2.0 optional package instead of JDBC 2.0 directly.For additional info see the JGuru JDBC FAQ Forum and see How do I access a database from my servlet? in the Servlets FAQ. [Also, http://www.javaexchange.com hosts a fine implementation of a JDBC Connection Pool. -Alex]
不过我发现一个问题,如果用weblogic 的jdriver for oracle,
中文出来是乱码,估计得自己解码
用orcle 自己的jdbc driver,中文出来是正确的.我用的是weblogic 6.0 sp2,oracle 8.1.6.
如果用orcle 8.1.6 的jdbc driver 来连oracle 7.3.4 的话,
得到的中文字符串会被截掉,而且我没发现有什么规律.
