Posted by: tozx96 Posted on: 2003-09-03 17:19 我的环境是:jboss-3.2.0_tomcat-4.1.24(MS JDBC驱动程序),MSSQLServer2000数据库,Windows2000 Professional操作系统。 刚开始时系统运行时正常的,不过运行一段时间后,任何对数据库的请求都会抛出javax.resource.ResourceException: No ManagedConnections Available!异常。是不是我把一些资源用了后没有释放造成的。我对数据库的操作都是通过实体Bean(CMP)进行的。请大家帮忙,谢谢。以下是具体异常的片段: javax.resource.ResourceException: No ManagedConnections Available! at org.jboss.resource.connectionmanager.InternalManagedConnectionPool.ge tConnection(InternalManagedConnectionPool.java:183) at org.jboss.resource.connectionmanager.JBossManagedConnectionPool$OnePo ol.getConnection(JBossManagedConnectionPool.java:648) at org.jboss.resource.connectionmanager.BaseConnectionManager2.getManage dConnection(BaseConnectionManager2.java:413) at org.jboss.resource.connectionmanager.TxConnectionManager.getManagedCo nnection(TxConnectionManager.java:331) at org.jboss.resource.connectionmanager.BaseConnectionManager2.allocateC onnection(BaseConnectionManager2.java:488) at org.jboss.resource.connectionmanager.BaseConnectionManager2$Connectio nManagerProxy.allocateConnection(BaseConnectionManager2.java:798) at org.jboss.resource.adapter.jdbc.WrapperDataSource.getConnection(Wrapp erDataSource.java:102) |
