[jboss-user] [Datasource Configuration] - Wrapping to OracleConnection problem.
Hi all,
I using JBoss 4.2.3 and i need to get an OracleConnection to be able to pass an array as
parameter to a PreparedStatement. I get an exception when i cast de connection:
java.lang.ClassCastException: $Proxy1 cannot be cast to
org.jboss.resource.adapter.jdbc.WrappedConnection
I don??t know what i am doing wrong. This is my code:
DataSource ds = (DataSource)
context.lookup("MLS/SRVC/AdministrationDataSource");
Connection con = ds.getConnection();
// The exception is thow here
WrappedConnection wrappedConn = (WrappedConnection)con;
OracleConnection ocon = (OracleConnection) wrappedConn.getUnderlyingConnection();
// This is what i need to do.
ArrayDescriptor af =
ArrayDescriptor.createDescriptor("MDSYS.SDO_ORDINATE_ARRAY", con);
And this is the xml descriptor:
<no-tx-datasource>
<jndi-name>MLS/SRVC/AdministrationDataSource</jndi-name>
<use-java-context>false</use-java-context>
<connection-url>jdbc:oracle:thin:@x.x.x.x:1521:xxx</connection-url>
<driver-class>oracle.jdbc.driver.OracleDriver</driver-class>
<user-name>xxx</user-name>
xxx
<min-pool-size>3</min-pool-size>
<max-pool-size>10</max-pool-size>
<idle-timeout-minutes>3</idle-timeout-minutes>
<track-statements>true</track-statements>
<valid-connection-checker-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleValidConnectionChecker</valid-connection-checker-class-name>
<exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleExceptionSorter</exception-sorter-class-name>
<type-mapping>Oracle 9i</type-mapping>
</no-tx-datasource>
Thanks for any help or clue
