----------------------------
> Getting Exception when trying to get the PrepareStatement from Connection
> From DBCP Pool
> ----------------------------------------------------------------------------------------
>
> Key: DBCP-366
> URL: https://issues.apache.org/jira/browse/DBCP-366
> Project: Commons Dbcp
> Issue Type: Bug
> Affects Versions: 1.2.2
> Environment: Linux machine
> Reporter: saroj kumar balusu
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> Using commons-dbcp-1.2.2.jar version with Tomcat version 6.0.29.
> Getting the following exception when trying to get the
> java.sql.PrepareStatement using a Connection from DBCP Pool:
> {noformat}
> java.sql.SQLException: Connection is closed.
> at
> org.apache.commons.dbcp.PoolingDriver$PoolGuardConnectionWrapper.checkOpen(PoolingDriver.java:263)
> at
> org.apache.commons.dbcp.PoolingDriver$PoolGuardConnectionWrapper.prepareStatement(PoolingDriver.java:366)
> {noformat}
> This is the configuration we are using for creating Connection Pool from DBCP:
> {code:java}
> public static void setupDriver(String connectURI, String userName,
> String dbPassword, String maxActive, String minIdle,
> String maxWait, String poolName) throws Exception {
> GenericObjectPool.Config config = new
> GenericObjectPool.Config();
> config.maxActive = Integer.parseInt(maxActive);
> config.minIdle = Integer.parseInt(minIdle);
> config.maxWait = Integer.parseInt(maxWait);
> config.whenExhaustedAction = 2;
> config.minEvictableIdleTimeMillis = 1800000;
> config.timeBetweenEvictionRunsMillis = 1800000;
> config.numTestsPerEvictionRun = 3;
> config.testOnBorrow = true;
> config.testOnReturn = true;
> config.testWhileIdle = true;
> ObjectPool connectionPool = new GenericObjectPool(null, config);
> ConnectionFactory connectionFactory = new
> DriverManagerConnectionFactory(
> connectURI, userName, dbPassword);
> PoolableConnectionFactory poolableConnectionFactory = new
> PoolableConnectionFactory(
> connectionFactory, connectionPool, null, null,
> false, true);
> poolableConnectionFactory.setValidationQuery("select 1 from
> dual");
> driver = new PoolingDriver();
> driver.registerPool(poolName, connectionPool);
> driver.setAccessToUnderlyingConnectionAllowed(true);
> // PoolingDataSource dataSource = new
> PoolingDataSource(connectionPool);
> // return dataSource;
> }
> {code}
> The following code is used to get the Connection:
> {code:java}
> public java.sql.Connection getConnection(poolName) {
> Connection con =
> DriverManager.getConnection("jdbc:apache:commons:dbcp:"+poolName);
> return con;
> }
> {code}
> The following code is used to release the connection:
> {code:java}
> public void release(Connection conn) throws DBException {
> try {
> conn.close();
> } catch (Exception e) {
> throw new Exception(e.getMessage(), e);
> }
> }
> {code}
> Can you let us know what might be the exact reason for the following
> exception?
