Mark Thomas resolved DBCP-461.
------------------------------
Resolution: Invalid
This is nothing to do with DBCP. The OP is using Tomcat's own pooling
implementation.

> Prepared statements are not cached with XA
> ------------------------------------------
>
> Key: DBCP-461
> URL: https://issues.apache.org/jira/browse/DBCP-461
> Project: Commons DBCP
> Issue Type: Bug
> Affects Versions: 1.4
> Environment: TomEE Version : Apache Tomcat Version 7.0.63
> Reporter: Sailaja
> Priority: Major
>
> Prepared statements are not getting cached when I use XA datasource.
> Please find the below program :
> {code:java}
> public static void main(String[] args) throws Exception {
> final TransactionManager transactionManager =
> TransactionManagerFactory.getTransactionManager();
> final PoolProperties poolProperties = new PoolProperties();
> SQLServerDataSource dataSource = new
> com.microsoft.sqlserver.jdbc.SQLServerDataSource();
> dataSource.setUser("sa");
> dataSource.setPassword("$9Lserver");
>
> dataSource.setURL("jdbc:sqlserver://sdwivedi63ks022:1433;sendStringParametersAsUnicode=false");
> dataSource.setDatabaseName("himalaya");
> poolProperties.setDataSource(dataSource);
> final String jdbcInterceptors =
> "org.apache.tomcat.jdbc.pool.interceptor.StatementCache(prepared=true,callable=true)";
> poolProperties.setJdbcInterceptors(jdbcInterceptors);
> final org.apache.tomcat.jdbc.pool.DataSource pooledOracleDatasource =
> new org.apache.tomcat.jdbc.pool.XADataSource(poolProperties);
> final javax.sql.DataSource oracleDataSource = new
> org.apache.openejb.resource.jdbc.managed.xa.ManagedXADataSource(pooledOracleDatasource,
> transactionManager,
> TransactionProvider.getTransactionSynchronizationRegistry());
> Connection connection = oracleDataSource.getConnection();
> for (int i = 0; i < 50; i++) {
> PreparedStatement preparedStatement =
> connection.prepareStatement("insert into MyTableNew values (" + i + ")");
> System.out.println(preparedStatement.getClass().getName());
> preparedStatement.execute();
> preparedStatement.close();
> }
> connection.close();
> }
> {code}
> If I run the above program, the output I see is:
> com.sun.proxy.$Proxy11
> If I just change the above program to use XA datasource, i.e.
> Change the following line
> SQLServerDataSource dataSource = new
> com.microsoft.sqlserver.jdbc.SQLServerDataSource();
> To
> SQLServerXADataSource dataSource = new
> com.microsoft.sqlserver.jdbc.SQLServerXADataSource();
> The output is :
> com.microsoft.sqlserver.jdbc.SQLServerPreparedStatement
