spring配置sqlserver2000，出现java.sql.SQLWarning
项目中应用到spring配置sqlserver2000，用com.mchange.v2.c3p0.ComboPooledDataSource来做连接池，具体配置如下：
结果在程序中得到连接后报如下信息（各种包已经正确导入）：java.lang.AbstractMethodErrorat com.mchange.v2.c3p0.impl.NewPooledConnection.carefulCheckHoldability(NewPooledConnection.java:117)at com.mchange.v2.c3p0.impl.NewPooledConnection.<init>(NewPooledConnection.java:109)at com.mchange.v2.c3p0.WrapperConnectionPoolDataSource.getPooledConnection(WrapperConnectionPoolDataSource.java:198)at com.mchange.v2.c3p0.WrapperConnectionPoolDataSource.getPooledConnection(WrapperConnectionPoolDataSource.java:171)at com.mchange.v2.c3p0.impl.C3P0PooledConnectionPool$1PooledConnectionResourcePoolManager.acquireResource(C3P0PooledConnectionPool.java:137)at com.mchange.v2.resourcepool.BasicResourcePool.doAcquire(BasicResourcePool.java:1014)at com.mchange.v2.resourcepool.BasicResourcePool.access$800(BasicResourcePool.java:32)at com.mchange.v2.resourcepool.BasicResourcePool$AcquireTask.run(BasicResourcePool.java:1810)at com.mchange.v2.async.ThreadPoolAsynchronousRunner$PoolThread.run(ThreadPoolAsynchronousRunner.java:547)[DateTime] 2010/12/31/ 17:26:26 [PRIORITY] INFO [MDC] [THREAD] com.mchange.v2.async.ThreadPoolAsynchronousRunner$PoolThread-#1 [CATEGORY] com.mchange.v2.c3p0.SQLWarnings[MESSAGE] [Microsoft][SQLServer JDBC Driver]Database changed to fookjava.sql.SQLWarning: [Microsoft][SQLServer JDBC Driver]Database changed to fookat com.microsoft.jdbc.base.BaseWarnings.add(Unknown Source)at com.microsoft.jdbc.sqlserver.tds.TDSRequest.processEnvChange(Unknown Source)at com.microsoft.jdbc.sqlserver.tds.TDSRequest.processReplyToken(Unknown Source)at com.microsoft.jdbc.sqlserver.tds.TDSLoginRequest.processReplyToken(Unknown Source)at com.microsoft.jdbc.sqlserver.tds.TDSRequest.processReply(Unknown Source)at com.microsoft.jdbc.sqlserver.SQLServerImplConnection.open(Unknown Source)at com.microsoft.jdbc.base.BaseConnection.getNewImplConnection(Unknown Source)at com.microsoft.jdbc.base.BaseConnection.open(Unknown Source)at com.microsoft.jdbc.base.BaseDriver.connect(Unknown Source)at com.mchange.v2.c3p0.DriverManagerDataSource.getConnection(DriverManagerDataSource.java:134)at com.mchange.v2.c3p0.WrapperConnectionPoolDataSource.getPooledConnection(WrapperConnectionPoolDataSource.java:182)at com.mchange.v2.c3p0.WrapperConnectionPoolDataSource.getPooledConnection(WrapperConnectionPoolDataSource.java:171)at com.mchange.v2.c3p0.impl.C3P0PooledConnectionPool$1PooledConnectionResourcePoolManager.acquireResource(C3P0PooledConnectionPool.java:137)at com.mchange.v2.resourcepool.BasicResourcePool.doAcquire(BasicResourcePool.java:1014)at com.mchange.v2.resourcepool.BasicResourcePool.access$800(BasicResourcePool.java:32)at com.mchange.v2.resourcepool.BasicResourcePool$AcquireTask.run(BasicResourcePool.java:1810)at com.mchange.v2.async.ThreadPoolAsynchronousRunner$PoolThread.run(ThreadPoolAsynchronousRunner.java:547)java.sql.SQLWarning: [Microsoft][SQLServer JDBC Driver]Language changed to us_englishat com.microsoft.jdbc.base.BaseWarnings.add(Unknown Source)at com.microsoft.jdbc.sqlserver.tds.TDSRequest.processEnvChange(Unknown Source)at com.microsoft.jdbc.sqlserver.tds.TDSRequest.processReplyToken(Unknown Source)at com.microsoft.jdbc.sqlserver.tds.TDSLoginRequest.processReplyToken(Unknown Source)at com.microsoft.jdbc.sqlserver.tds.TDSRequest.processReply(Unknown Source)at com.microsoft.jdbc.sqlserver.SQLServerImplConnection.open(Unknown Source)at com.microsoft.jdbc.base.BaseConnection.getNewImplConnection(Unknown Source)at com.microsoft.jdbc.base.BaseConnection.open(Unknown Source)at com.microsoft.jdbc.base.BaseDriver.connect(Unknown Source)at com.mchange.v2.c3p0.DriverManagerDataSource.getConnection(DriverManagerDataSource.java:134)at com.mchange.v2.c3p0.WrapperConnectionPoolDataSource.getPooledConnection(WrapperConnectionPoolDataSource.java:182)at com.mchange.v2.c3p0.WrapperConnectionPoolDataSource.getPooledConnection(WrapperConnectionPoolDataSource.java:171)at com.mchange.v2.c3p0.impl.C3P0PooledConnectionPool$1PooledConnectionResourcePoolManager.acquireResource(C3P0PooledConnectionPool.java:137)at com.mchange.v2.resourcepool.BasicResourcePool.doAcquire(BasicResourcePool.java:1014)at com.mchange.v2.resourcepool.BasicResourcePool.access$800(BasicResourcePool.java:32)at com.mchange.v2.resourcepool.BasicResourcePool$AcquireTask.run(BasicResourcePool.java:1810)at com.mchange.v2.async.ThreadPoolAsynchronousRunner$PoolThread.run(ThreadPoolAsynchronousRunner.java:547)
应该如何解决？
