Application development overview
// Iterate over the ResultSet. The example here positions the cursor on the
// first row and then iterates forward through the contents of the ResultSet.
// Appropriate get methods are then used to retrieve column values.
rSet.beforeFirst();
while ( rSet != null && rSet.next() )
{
// get the column values for the current row using the appropriate
// get methods
}
// This illustrates reverse iteration through the ResultSet
rSet.afterLast();
while ( rSet.previous() )
{
// get the column values for the current row using the appropriate
// get methods
}
// Extend the Record interface to represent an EIS-specific custom Record.
// The interface CustomerRecord supports a simple accessor/mutator design
// pattern for its field values. A development tool would generate the
// implementation class of the CustomerRecord
public interface CustomerRecord extends javax.resource.cci.Record,
javax.resource.cci.Streamable
{
public void setName( String name );
public void setId( String custId );
public void setAddress( String address );
public String getName();
public String getId();
public String getAddress();
}
// Create an empty CustomerRecord instance to hold output from
// the execution of an Interaction
CustomerRecord customer = // ... create an instance
// Create a PurchaseOrderRecord instance as an input to the Interaction
// and set properties on this instance. The PurchaseOrderRecord is another
// example of a custom Record
PurchaseOrderRecord purchaseOrder = // ... create an instance
purchaseOrder.setProductName( "..." );
purchaseOrder.setQuantity( "..." );
// ...
// Execute an Interaction that populates the output CustomerRecord instance
boolean crResponse = ix.execute( rsIxSpec, purchaseOrder, customer );
// Check the CustomerRecord
System.out.println( "Customer Name = [" + customer.getName() + "],
Customer ID = [" + customer.getId() + "],
Customer Address = [" + customer.getAddress() + "]" );
