WeblogicConnectionPool

public WeblogicConnectionPool()

Method Detail

setJNDIContext

public void setJNDIContext(javax.naming.Context JNDIContext)
                    throws BMPException

Inform provider of ejbContext. The implementation of this interface has have a public, default no-args constructor. The provider relies on properties in the bean's deployment descriptor as documented in a provider or Theory Center specified protocol.

Specified by:

setJNDIContext in interface SmartConnectionPool

Parameters:

ejbContext - the bean's ejbContext.

getConnection

public java.sql.Connection getConnection()
                                  throws BMPException

Returns the SQL Connection for this Transaction. The actual implementation may choose to implement connection pooling etc.

Specified by:

getConnection in interface SmartConnectionPool

Returns:

conn Connection object.

Throws:

BMPException - implementation specific exception occurred

releaseConnection

public void releaseConnection(java.sql.Connection connection)
                       throws BMPException

Releases the SQL Connection for this Transaction.

Specified by:

releaseConnection in interface SmartConnectionPool

Parameters:

conn - Connection object.

Throws:

BMPException - implementation specific exception occurred

initializePreparedStatementCache

public java.lang.Object initializePreparedStatementCache(java.lang.Object requestor,
                                                         int nInitialSize,
