我们计划配置C3P0设置，以避免应用服务器端和Java独立应用程序的数据库连接问题。 对于服务器端应用程序，我们已经配置了AS7TransactionManagerLookup＆＃39;作为Transaction Manger和C3P0作为连接池，对于java独立应用程序，我们已经配置了＆＃39; BTMTransactionManagerLookup＆＃39;作为事务管理器，C3P0作为连接池。
在jBoss应用服务器C3P0设置正常工作。但对于独立应用程序，它不起作用。您能否建议，我可以将BTM用作事务管理器，将C3P0用作java独立的连接池吗？我已经提交了我的参考资料。
我们使用了spring版本＆＃34; 3.1.1.RELEASE＆＃34;，hibernate版本＆＃34; 3.6.9.Final＆＃34;和c3p0版本＆＃34; 0.9.5.1＆＃34;。
